* NOTES SINCE PUBLICATION * 1. In the video I make reference to MCS, a certification scheme, normally required by energy providers before they can provide certain services like paid export. There are now other similar schemes, including FlexOrb that energy providers are accepting as well. Competition in this area is good as it will help keep the pricing of these schemes down. 2. Also in the video, I talk about the effect of shading on a single panel affecting all the other panels. In actual fact, it depends of the type of shading. If the shading is hard (for example, from a chimney or another building) then the panel is able to protect itself (via bypass diodes) without affecting any the other panels in the string. If the shading is diffuse or limited (for example, a TV antenna or cable) then this could well affect the other panels because that kind of shading is not sufficient to activate the bypass diodes in that panel. See this video for a more complete explanation: ruclips.net/video/9GvhDhCSJgo/видео.html
One of the companies I priced for Solar panels was $65,000 for my home, It would take me 36 years to pay for that at the cost of what I pay for my light bill now.
@@AnthonyAlvarado78 My light bill is around $100 a month, at a cost of $65,000, it is not feasible in any form or fashion to buy solar. Our state does not help that much to make enough of a difference. It would actually take me more than 36 years to pay that off, at the cost of what I'm paying now for my light bill.
Thanks Chris 👍🏻 yeah, there are too many Solar videos out there that are highly biased. I’ll continue to keep things neutral, especially with an upcoming video on panel shading! 😳
Thank you for clear explanation of Basic PV for homeowners! ! 🌞 re: 'Return on Investment' Time...as I have been explaining to U.S. customers for decsdes, they need to ask the utilities "When will my Electric Bill pay-off??". Of course the Answer is "Never" since buying energy monthly never has a 'pay-off' from grid suppliers & is only Renting your Energy forever!! In contrast, Your own PV system is Owning the energy Source so it Has a payback🌅🗽
Hi Gary. I've been searching through the various YT channels on this. Yours is the first one that has content I was looking for. I see you are just starting YT, and your delivery approach, the detail provided struck home for me. Thank you and I wish you the best. Great stuff!
Thanks very much for the kind words, John! Many people I've worked with over the years have told me I was pretty good at explain complex things in an easy way. And I was thinking about getting my own solar installation anyway, I thought why not share some of the knowledge I gained along the way :-) It turned out to be a lot of hard hours to put each video together, but feedback like this really makes it all worthwhile - thank you!
I third, John, just going in Solar panel (for a french installation) and your video is cristal clear with all the expected details it should be! Thanks a lot for your time and video
Really useful, and wish I had taken two different approaches when I accepted the design of my solar installation: 1. As you say, educate yourself, then get comparative quotes for the same configuration; and 2. start with desired payback period and then work backwards to select the design best suited to the design constraints. I got lucky with the second one, but got caught out on the first one as I have 3-phase supply to the home. Design would have been different if I'd known how the components worked in multiple phases. A video about multiphase installations certainly would have been useful!
Hi John, it's a tricky one eh? Just how much research should one do before taking the plunge? That's one of the reasons I starting making these videos, actually - to save people time, and to show that there is quite a bit to think about before buying an installation. It might be that you will change your setup over time, and so you can incorporate some of the benefits with 3-phase at that time - good luck! :-)
Really helpful video. I got quotes for a solar installation a couple of years ago and didn’t feel confident proceeding. I feel that after this video and others on this channel I could have another go.
OMG had to pause the video to just say "THANK YOU!" Thank you for taking time to explain this whole solar thing clearly. I can finally wrap my head around what a whole system looks like after spending hours going through other people vid.
Gary, Thank you so much for this video, I'm just starting on the solar/battery storage learning trail and I found this video remarkably comprehensive in explaining in, laymans terms, many of the questions I needed answered and the most surprising thing of all was I was expecting to find at the end of the video some sort of promotion for this or that particular equipment or that you were an installer, but no, just putting this info out there without looking for anything in return, quite a revelation in todays society, so again many thanks for your time and effort. best regards
Thanks Quintin - yeah, my driver for making the videos was primarily all about saving people tons of time wading through the minefield of information (and misinformation) about solar technology. If I can make any money on ad revenue etc. then that will go towards improving my recording setup (which is currently very basic). Feedback like this really makes it all worthwhile, so thank you for taking the time to comment! ❤️
Gary - the man of my dreams :). We had solar installed about a decade ago by a company that has subsequently gone out of business (and sold our contact details so we have been regularly approached by other companies ever since). I wish I had seen your videos back then. We had no explanation of how our system worked and how to maximise our use of it, so haven't really been using it well. We've also had a few blips - mostly with the Solar I-boost diverter - and found it stupidly hard to find help. Thanks for your empowering and professional video. Really good to see that not everyone in this field is a cowboy!
Thanks Gary. I'd like to point out one possibly helpful option -- at least here in the US. I used a Solar Co-op -- specifically Solar United Neighbors. They assembled a group of about 50 potential buyers in my city and put out a standardized RFP. We received 6 bids, which our selection committee reviewed in detail. Each installer quotes a sort of 'menu' panel/inverter/battery options, plus a schedule of possible additions (eg: long wire runs, warranty enhancements, etc). It even got into the weeds on such topics as diversity in hiring practices and community philanthropy. We had two experts from the Co-op help us evaluate the bids. It was a VERY informative process for those of us who volunteered for the selection committee. The selected vendor then visited each group member and prepared a custom proposal. The co-op experts checked the proposals to ensure that they conformed to the agreed group pricing and terms. The approach might not result in the absolute rock-bottom deal, but I think it's probably a better deal than 95% of us would have negotiated individually. And each group member is completely free to back out at any time before they sign their individual contract. Those that walked away did so with the group's negotiated price menu in hand.
This is very comprehensive..thank you for all the effort you've put into making this video. I've finally understood the difference between AC coupled and DC coupled!
Hi Afnan, it was all my pleasure! People have told me that I'm very good at explaining complex topics in a simple way (one of the reasons I started making these videos in fact), and so I'm very happy to hear my work has helped you too :-)
Wow. The perfect balance of simple and detailed. Ive done a fair bit off research and was really impressed with what ISNT in the video. Youre managed to include all the end steps of my research with out all the confusing intermediate knowledge to get there.
Hi Darren, I'm well chuffed that I've been able to help you understand solar! It's certainly a minefield topic. Thank you for watching - and I'll keep the videos coming! :-)
Gary, being in the process of "going solar" and getting quotes, I've found your video most helpful in some respects so great thanks for that. I think I prefer the idea of microinverters with an AC coupled battery (despite the potential power losses), i'm not sure the price difference from a string inverter is so pronounced anymore, particularly a string inverter with optimizers and most microinverters have a 25 year guarantee nowadays (Enphase) versus a string inverters 10 year to allay fears of inaccessible repairs. I presume this means peak power usage (without grid) is limited to ARRAY + BATTERY in daytime and BATTERY alone in the evenings. I noted the batteries in my quotes, (Give Energy, Solax, Alpha Smile B3) only have a maximum charge/discharge rate of 2.68 Kw. If my house is using (TV-300, Microwave-1000, Fridge-200, WIne Cooler-100, Lights - 150, PC-150) and I put the kettle on at 3000, will that switch seamlessly to drawing from the grid or am I likely to experience difficulties with appliances? I suspect I may be getting mixed up with off grid systems there? Do you see that level of battery discharge rate as a problem if one is desperate to not draw from the grid if possible? Are discharge rates of that magnitude standard across the industry or can you get larger, in general those figures don't appear to be a readily available from an internet search although I can find Tesla Powewall is 5Kw surging to 7.5Kw? I suspect I will be more conscious of using other high power appliances during daytime if possible but I do enjoy a cup of tea in the evening! Thanks again.
You'll find that your solar and battery system will seamlessly provide electricity to your appliances both with and without any grid requirement. And I don't know if you read about the latest Tesla Powerwall 3, but it's got a 11kW discharge rate, so no worries (at all) You'll be able to have that cup of tea and not draw anything from the grid :-)
I have Gary and it has a lovely £11,500 price tag and a waiting list over a year long when it eventually gets here so I'm priced right out of that one. I'm thinking about 2 x SolaX 5.8 LFP offering, I believe I've read that their lower end power output is increased if 2 batteries are wired in series together as master and slave but not sure if that's true, do you know?@@GaryDoesSolar
Am just looking at going solar and this video has been extremely useful. Many thanks for going to the trouble of putting this information together, it must have been a lot of work.
You're most welcome, Ian. Yeah, it was quite a few hours to put it together, but comments like this make it all worthwhile :-) Good luck with your solar journey!
@@GaryDoesSolar Have a survey appointment booked for early Nov, thanks to your videos I’ll be in a position where I know what questions to ask. Was already told the earliest I can get an installation would be 6-7 months away due to shortage of panels and batteries etc so plenty of time to do further research. Thanks again for the information, extremely useful. Have liked and subscribed 👍 Cheers.
A great video! It deals with many fundamental concepts that I could not find on other solar-power channels. Everything is relevant, it is well explained. Thank you!
Please, please, please keep the videos coming Gary. They are by far the best I've seen with regards to learning as much as possible about solar energy. I'm currently trying to find a sales role with a company but often they are just interested with people who have experience. Well I don't. although I have been involved with sales and marketing all my life but want now a new challenge. Maybe one of your subscribers might be able to point me in the right direction. Thanks again......
Hi, Gary. I am retired and moved from USA to the Philippines. Built a new house about 18 months ago. Regretably, I didn't give solar power a thought at the time. After about a year of experiencing what I thought were excessive monthy power bills ( USD $150 - $175), then it dawned on me that I should be using this tropical sunshine to my advantage. I am an
I am an absolute novice when it comes to solar power. So, I started checking things out on RUclips. Your site was about the fourth one I viewed. I wanted to let you know that I found your presentation very easy to follow and understand. I am looking forward to watching the rest of your videos and learning a more about solar power options. Keep up the good work, Gary.
Thanks Robert - great that you found my videos! I’m sure you won’t be a novice for long either 😎 Sounds like your move from USA to The Philippines went well - I wish you the very best, and I’ll try to keep the videos coming! 👍🏻
@@GaryDoesSolar Wow! Thanks so much for the quick reponse. I am really impressed. YOU ARE THE REAL DEAL, MATE!. So far, you are the only site to respond to my messages. It took a couple of years of researching the Philippines before l made the move. So far, regrets! The only regret is that I did not come when I was a little younger. Been here a little over 8 years already. I have wonderful wife of 8 yrs. We are in the process of adopting a 1 yr old Philippine boy. A new challenge my life. I am looking forward to seeing more of your videos. Take good care!
Well worth a watch and has given me some use full tips I am struggling to find a decent solar installer plenty of people who'll txt me a price but nothing in righting and other companies just turn up and no quotation, seems to me its a mine field just trying to find an installer. when I do ill refer to your video.
Thanks Bob - yeah, because a lot of people are trying to get solar installed, demand is very high against the number of installers available. This situation might exist for another year or so before things calm down, unfortunately. Hope you are able to find a good installer soon!
Great video thanks. I've always understood solar but never quite understood the various power ratings etc of the inverters, but this video is perfectly simplified and now I understand them too! Many thanks.
From one Gary to another, thank you so much for your impartial and clear advice. I thought I knew enough but I quickly discovered that wasn't the case! Your advice at the end about choosing an installer is top notch, all very valuable tips. I consume 20,000 kWh per year but no more than 20 panels can fit on my roof, so only 25% of the daily demand can be met by solar during the summer months. Less than 10% can be met during the winter months. Solar does seem rather pathetic in this light (pun!) but I don't know what else to do given that the Oct 2022 price increase will shove my bill up to £9K per year which pushes me closer into the growing "heat or eat" group.
Hi Gary, there are not enough of us Gary’s 🤣 Wow - 20MWh per annum! That’s about 3x my own use. Ok, so for my own (impending) installation, I’m looking at 19 x 400W panels and 2x9.5kWh batteries. This should cover my daily use of between 10-30kWh (the days with higher usage is mainly washing machines and tumble dryers - which could be load shifted). I’m building a spreadsheet for my next video which allows you try out various solar/battery configurations. I’m not sure it can solve your situation, but I’d be more than happy to send you a copy in advance for you to play around with? Just let me know…
Great video again, Gary. Something I've found when shopping for quotes is that MCS is now rivalled by FlexiOrb accreditation. They are the same standards, but I've been told by an installer that FlexiOrb charge an annual rate compared to MCS charging per install, so some installers prefer one over the other depending on volume. Not sure of the details on that as it's just what I've heard from a FlexiOrb-accredited installer. Perhaps unsurprisingly, all the MCS-accredited ones I've spoken to insist that MCS is the only accreditation worth anything. Crucially, Energy suppliers such as Octopus, British Gas, EON, Scottish Power, OVO and UW are now accepting FlexiOrb accreditation for SEG tariffs. Might be worth an update to the description, or even a short video explaining the new accreditation and certification standards. Cheers!
Thanks - this is a good point. And a welcome situation because it’s typically always detrimental to the consumer if there is a gate controlled by a single supplier (in this case, MCS). Competition drives better quality and price.
For this 2nd "Primer Video" you have indeed covered the major basic points which took me about 5 days to learn from scratch. Budget will always govern most installations (but shouldn't) as in my case, the front of my house is SW facing so I have 3 roof areas pointing in different directions all with clear views and good sunlight in morning/ afternoon/ evening that can be used (I'm changing my roof so going for in-roof system) and that puts me into optimised/ micro inverter category. Jury is still out on having a battery due to space (pointless having a small one) and Im not having it on view outside as thieves can easily isolate and steal them.
Great to hear that I’m covering the right topics 😀 your house situation does sound like a challenge, but from what you’re saying, you’ve got a promising solution! In-roof Solar sounds like a good plan - I think I’d probably do the same, but I’ve got quite a few velux windows to skirt around. I totally agree with you on the battery front - the biggest you can afford is likely the best way, and installing it inside the house would certainly not give any passer by reason to steal it! Hope all goes well with your setup, and if there are any topics you’d like me to consider for future videos, just let me know 👍🏻
I'm thinking about putting my battery (if I get one) in the unused chimney! I live in a Victorian terraced house so no real space to use but both chimneys are not used and the batteries are IP certified so should be fine in the chimney! Hopefully?
Thanks Gary I’m looking and you’ve given me so much info…always say INFORMATION IS KEY…nothing worse than looking for something and not knowing a bit info and being pushed into buying what you don’t want or need ..
I’m really surprised that there hasn’t been more talk of this on the tv..and I know you can get grants if your on some sort of benefits unlike most people out there .. But there needs to be a option or insensitive for working people ..
Totally agree, and I’m thinking that with energy now being on the forefront of everyone’s (including the government’s) mind, we can expect to see some positive changes in policy 👍🏻
You're very welcome, Rick - and all the best with your solar journey. I have other videos looking into the different aspects, which may be of help too :-)
Your videos are brilliant, so detailed, I believe ,after watching anything that people are unsure of are definitely made a lot clearer, your knowledge is priceless, you should start up your own solar company, you have the know how , you just need to employ people to install that With reference to quotes I’ve had a few and except for one ,they seem to quote for 4kw ,I suspect it’s because it’s the easiest option
Hiya. Thanks for the very kind words. My main activities are in mobile space, would love to have more time so I could get more involved in the energy sector, as it's such an interesting space! If you're in the UK, then the 4kW quotes are a lot easier for installers as they only require G98 certification, which is far easier to complete than G99...
A little correction, microinverters should not be the more expensive option, it should be the same as a system that use optimizers, let says is buy a 10kw String inverter for £2.000 (SolarEdge) and you install 27 panels (370w each) for a 9,9kW system array, when you divide 2.000/27= $75, then an optimizer will cost you around $60 (or more) each, the total is around £135+ per panel, which is very similar to a microinverter like Enphase IQ7A, £160 each (and now cheaper with the new IQ8 series). This is just an example, the String Inverter + Optimizers is more expensive when you install a smaller array system, because a 5kW won't cost you half price of a 10kW S. Inverter, so the cost per panel is a little higher, and keep in mind when you use that setup, you have 3 points of failure (panel/optimizer/inverter), while with a microinverter you only have 2, besides Enphase provide a 25 years of warranty.
Thank you Gary as this video is very helpful especially when like me knowing nothing about solar panels and batteries, can't thank you enough for your knowledge on this subject as its going to be a BIG help in knowing the right questions to ask .
Thanks Susan - it took me many, many hours to make these videos and your feedback alone has made it all worthwhile. Good luck with your solar journey! 😀
Morning Gary. Well that an excellent explanation you have given us, will pass this video on to someone who is considering this. I have had solar for 7 years best thing we ever did, got our money back in under 5 years, now charging two cars and heating / cooling our house via Solaredge and Solax battery. Thanks Bob Blood Kent England.
Thanks for the great feedback, Bob! I'm very jealous because I'm still waiting to get my installation done (long story about a supplier that let me down) and you've not only got your installation, but you're already past the breakeven point! Well done! Are you considering any additional components or do you think your system is complete now?
Thanks Craig. Now, with regard to Scottish companies - are you sure they don't require to be registered to Companies House? See this link: www.mygov.scot/contact-companies-house
Hi Gary - just looking through more of your videos and getting the info for micro inverters - all great info - I need to store on DC batteries too so that makes it a bit more of an issue with another standalone inverter - I'll get there ....... As far as companies house - every LTD company needs registered and I was told every VAT registered business in England needs to register but for some reason not Scotland - My company for 12 years has not needed to register and I am VAT registered (So - many smaller businesses may chose not to register - most of the bigger businesses are LTD and there for find it compulsory) @@GaryDoesSolar
@@craigstewart1878 Ah ok - I was referring to LTD companies - they need to be registered. If you're working as a sole trader or partnership, maybe you don't need to register.
Hi Gary. Like many I imagine, I am new to solar prompted by the expected increase in electricity and gas bills. I've watched umpteen videos and read tens of thousands of words. I could have saved myself loads of time and effort and just watched your videos instead. They provide clarity in the midst of confusion. Many thanks for taking the time to do this.
Hello Gary, thank you for such a clear video. Until I discovered it I had been floundering around in the dark. I recently 'expressed an interest in a local authority group buying scheme. The winning bid by the solar/battery provider will be the cheapest I suspect. My concern with this is that I would have limited input in what they want to supply to me (solar panels/inverter/battery). You have given me some idea of how to consider whether their offering is right for me. Exactly what I needed at the right time.
Really helpful and thought- provoking for me. The other topics I'd love to know more about are - 'add-on' roof panels vs built-in (I'm needing to grt some roof work done as my tiled roof in old and not felted). I wonder if combining the work would be better and having 'inbuilt' panels ? - what other mods are needed to the house ? Eg will in need a new consumer unit as it's adding a new circuit? (And plastic ones now verboten on upgrades (even though 90% of us have them) - where can and can't the equipment (inverter, battery etc) be located- my garage is detached and too far away) - can solar set-ups be put on out-buildings and 'piped back' into the house ? (Eg my detached garage)
Comprehensive video. Regarding shading at the13.00 minute mark, there was no mention of module internal by pass diodes that help elevate power loss when shading occurs. This is an adequate solution more often than not so it is not always necessary to install optimisers to solve shading issues. Well presented video Gary, very good.
Hi Craig, thanks very much for the kind words. And yes - a good spot! As it happened, I wasn't aware of bypass diodes when I made the video. I thought I should investigate deeply when I had some comments about the claims of the optimiser/microinverter manufacturers. This resulted in a dedicated video on shading.
Thanks, Gary, really informative, we are just starting to gather the information we have a flat roof above our flats with E7 off-peak heating supply, so are looking at solar supply in the day and E7 charge of batteries at night. Thanks for your channel you have a great presentation and keep it simple.
Hi Stephen, thanks very much for your kind words - and I wish you the best with your solar/battery plans. I do like the fact that Economy 7 tariffs are coming back into fashion. If you're wish Octopus, you might also want to look at their new Flux tariff - I'm creating a video on that tariff at the moment...
Very useful, informative and professionally-produced video, Gary. Thanks so much. I've had a 3kw 12-panel system for 9 years now. It's great to have such a detailed explanation of what I have had running all this time and interesting to see how the hardware has changed over the years. Mine are discontinued 250w panels at 15.4% efficiency. Not great now but good at the time. Still, they'll last another 15 years so not worth changing them. Great advice on how to spot a dependable EV installer. I need one for support as my inverter is nearing the end of its expected life and my accredited supplier told me about the optimisers now available. They weren't included in my setup so I'm having them retrofitted. At least I now know, independently what they're for and how they work. I'll send them the link to this video so they can recommend it to their prospective and existing customers as a useful independent reference work. You should be mandatory viewing for everyone in the market for solar! Thanks so much!
Thanks Gary - that's very kind of you to say - and great that I've been able to add to your knowledge. I wish I'd got into solar 9 years ago like you did! :-)
@@GaryDoesSolar So G98 application is always acceptable and there is no rejection as it's less than 3.68Kw (AC-power) but there is chance of rejection in G99 , is that what you are saying ? Kindly guide in more detail please , thanks.
I got a 55w panel on my east facing balkony. And, well it seems worth the price. Even with the ecoflow rover solar generator included. For the current price of electricity here. I may save its worth in a couple years already for the hours i get. In scandinavian summer where the sun never sets. Does not work in the evening. What i measured from the panel is under one amp of current, so two panels might get it to charge with that. I need to find proper places for the panels before i get another, so not happening too soon. Has definitely been worth it for the exitement. I got it mainly out of interest rather than economics, but yea it sort of makes sense moneywise too. Plus. The ecoflow is just about enough to keep my fridge running through a night of outage. Haven't tested that though, may need more startup watts..
great video.your deep explaination just gave me a great knowledge and understanding about solar and it installation.watching you from ghana west africa
Really useful video. What is apparent is that a large part of the cost involved is not related to physical equipment but to istallation costs and the overheads and marketing costs of the installing company. Then there are certification costs if you want the system to be connected to the grid. I have been thinking about an alternative route; a DIY installation with no export to the grid.The only bit I haven't got my head around is connecting to the house that isn't Heath Robinson!! My House faces East West but I have a south facing shed and will soon have a carport with similar orientation and reckon between them they would support an array of about 4KW. DIY would cut the cost by around 40% or more. Even more if I built the battery myself.
Great video Gary! Great to see you are still explaining complex things in a straight forward way! I've been on the solar journey for 2 years now and still learning!
Hey Mark! You found me on RUclips! Who'd have thought, eh? :-) Thanks for the kind words - great to hear I can still do it! I'll text you early next week if that's ok. Would love to catch up with you :-)
Gary, For those in USA, or anyone else that can verify whether PVwatts is the only available tool for measuring each plane for rooftop mounted solar array? Thx 👍 Keep up the great attention to detail on the content🙌
Thanks for your very kind words about my videos! :-) Worth watching this video I made about Google's Solar API: ruclips.net/video/LFiV--uzjh8/видео.html
Thank you for producing an excellent video which I found to be very clear and simple to understand. Like many others I am starting to think seriously about installing solar and your explanations have given me a basic grasp of the components used, their functions and various options. It will also enable me to have some rather more informed discussions with potential installers.
Very informative and clear explanation helping very much with my research into solar pv options for our home. Thankyou - ‘A’ level physics just about starting to come back to me…..
Great video, after checking hundreds on them, well laid out with clear understandable information, please make more videos with info on your installation if you have one and how much electricity is generated from Nov to feb in uk thank you.
Thanks for the kind words. My own solar journey has been a nightmare. All being well, it’ll be installed in January. I’ll maybe make a video about it 👍🏻
Excellent first two videos. Gary, hope you will do some more. . You are the right person , with the right channel at the right time to be offering potential individual household solutions on the energy crisis. Good luck with it
Hi Dennis, thanks very much - wow! It's a lot of work, but if I can help even just a few people make the leap and cut their energy bills over time, I'll be well happy! Next video out very soon...
Hi Gary, As with everyone else who've watched your videos, I am so grateful to you for providing this extremely well-presented information at exactly the right time for me. It was amazing that, as I watched, a question would come into my mind only for you to cover it almost immediately! I'm on the brink of making the important decisions, so these videos are perfect. Thanks again.
Hi Phil, thanks for taking the time to make this comment - wow! I’m humbled. And glad to have got round to it all in time for you! 😀 I’ve just published my next video which you might find useful too 👍🏻
Brilliant video, could you do a video on the survey process and the software used by installers to build the system on your roof? Like open solar and easy pv etc..
Gary, I've been looking for a vid that brings together all of the key points, this is it. Comprehensive and with appropriate level of detail I have all of the building blocks to enable me to give my solar project the green light. Many thanks
Thank you Gary, this is the most basic and very very useful video I have found online for installing solar panel. Now I know what to look for and what questions to ask when I go ahead with my project. Thanks ever so much. I have given you a thumbs up and subscribed.
Gary! What a sensational video, love seeing a thought leader break down solar and explain it as if we were all 5 years old. This is the exact type of content that needs to be readily available before people decide to invest in solar. I would love to hear your thoughts on some brand-new software we've just created. Gary, could you reach out to me as I have an opportunity for you which I think you'll be very excited about.
Hi Harry, thanks for the kind words. Sorry though, I’m not in the market for lead generation software - that’s not what my channel is about. All the best as you market it to others.
@@GaryDoesSolar Thanks Gary, apologies, I am not trying to sell you software. I wanted to gather your feedback on it seeing as you're a thought leader. Let me know if you'd like to hear a bit more to see if it fits with your values.
It took quite a few hours to put it all together (really, rally hard work) but comments like this make it all worthwhile - thanks Mike! :-) All the best with your solar journey - I'd love to hear how you get on. My own journey is actually only just starting...
@@GaryDoesSolar your research is something I would of done and spent weeks and weeks doing, so really appreciated. Yes when I do go ahead I let you know 👍
Black Belt Barrister on RUclips nearly got his finger burnt chosing a roof panel solar system. Well worth a visit, especially if you're considering a home presentation. The same applies if you're considering double glazing windows.
Thank you sir for this very information and thorough presentation on Solar Energy Generation. You covered almost everything in professional details. I liked your channel and I appreciate your sharing with the general public. Thank you very much.
Great video. One question though and not covered is the integration of battery storage in a grid tied existing system on a FIT. I imagine an AC coupled inverter is the only choice unless the existing string inverter is swapped out for a hybrid and then, metering will need to be checked so as not to effect the FIT readings.
Now, I don't have a FiT setup myself, so I'm only going on what I've heard from others. My understanding is that so long as you don't alter your FiT setup (e.g. do not swap out your inverter for another), then provided to you inform the FiT scheme of the changes (specifically only additions) you're making to your home, everything should be fine. For example, you can add a battery, but it must be AC-coupled with it's own inverter (built-in or otherwise). You can also add more panels, but they must be on a separate inverter to the existing panels.

1. In the video I make reference to MCS, a certification scheme, normally required by energy providers before they can provide certain services like paid export. There are now other similar schemes, including FlexOrb that energy providers are accepting as well. Competition in this area is good as it will help keep the pricing of these schemes down.
2. Also in the video, I talk about the effect of shading on a single panel affecting all the other panels. In actual fact, it depends of the type of shading. If the shading is hard (for example, from a chimney or another building) then the panel is able to protect itself (via bypass diodes) without affecting any the other panels in the string. If the shading is diffuse or limited (for example, a TV antenna or cable) then this could well affect the other panels because that kind of shading is not sufficient to activate the bypass diodes in that panel. See this video for a more complete explanation: ruclips.net/video/9GvhDhCSJgo/видео.html
Thanks for the clarification. Can I suggest you pin this comment to the top?
One of the companies I priced for Solar panels was $65,000 for my home, It would take me 36 years to pay for that at the cost of what I pay for my light bill now.
@docbrown6550 most states have rebates and SRECs available to reduce that burden. Most of my analysis came back at a 5 year pay for itself cost.
@@AnthonyAlvarado78 My light bill is around $100 a month, at a cost of $65,000, it is not feasible in any form or fashion to buy solar. Our state does not help that much to make enough of a difference. It would actually take me more than 36 years to pay that off, at the cost of what I'm paying now for my light bill.
That's not true anymore. Modern technology limits it to the one panel
This is the best ‘introduction to Solar’ video I’ve seen by far. Thanks for all the useful info!
Thanks Marios - that's very kind of you to say :-)
Clear-headed, logical with no axe to grind. Thank you, Gary
Thanks Chris 👍🏻 yeah, there are too many Solar videos out there that are highly biased. I’ll continue to keep things neutral, especially with an upcoming video on panel shading! 😳
Thank you for clear explanation of Basic PV for homeowners! ! 🌞 re: 'Return on Investment' Time...as I have been explaining to U.S. customers for decsdes, they need to ask the utilities "When will my Electric Bill pay-off??". Of course the Answer is "Never" since buying energy monthly never has a 'pay-off' from grid suppliers & is only Renting your Energy forever!! In contrast, Your own PV system is Owning the energy Source so it Has a payback🌅🗽
Love it! :-)
Hi Gary. I've been searching through the various YT channels on this. Yours is the first one that has content I was looking for. I see you are just starting YT, and your delivery approach, the detail provided struck home for me. Thank you and I wish you the best. Great stuff!
Thanks very much for the kind words, John! Many people I've worked with over the years have told me I was pretty good at explain complex things in an easy way. And I was thinking about getting my own solar installation anyway, I thought why not share some of the knowledge I gained along the way :-) It turned out to be a lot of hard hours to put each video together, but feedback like this really makes it all worthwhile - thank you!
I second John, one of the best solar information video focus on UK market
I third, John, just going in Solar panel (for a french installation) and your video is cristal clear with all the expected details it should be! Thanks a lot for your time and video
I agree
The best videos on solar PV RUclips -so far
I am currently looking at Solar and your videos are providing a great source of information.
Thanks Gary, for taking the time to comment - that's really great to hear :-) All the best with your plans!
Really useful, and wish I had taken two different approaches when I accepted the design of my solar installation: 1. As you say, educate yourself, then get comparative quotes for the same configuration; and 2. start with desired payback period and then work backwards to select the design best suited to the design constraints. I got lucky with the second one, but got caught out on the first one as I have 3-phase supply to the home.
Design would have been different if I'd known how the components worked in multiple phases. A video about multiphase installations certainly would have been useful!
Hi John, it's a tricky one eh? Just how much research should one do before taking the plunge? That's one of the reasons I starting making these videos, actually - to save people time, and to show that there is quite a bit to think about before buying an installation. It might be that you will change your setup over time, and so you can incorporate some of the benefits with 3-phase at that time - good luck! :-)
Really helpful video. I got quotes for a solar installation a couple of years ago and didn’t feel confident proceeding. I feel that after this video and others on this channel I could have another go.
Cheers - and it's comments like this that tell me I'm doing something really worthwhile - thank you! :-)
Comprehensive and great analysis on pros and cons. Clear and simple language. That's all I needed
Thanks for this great feedback, George 😀👍🏻
OMG had to pause the video to just say "THANK YOU!"
Thank you for taking time to explain this whole solar thing clearly. I can finally wrap my head around what a whole system looks like after spending hours going through other people vid.
You're most welcome, and so great to hear feedback like this. You've made my day! :-)
Gary, Thank you so much for this video, I'm just starting on the solar/battery storage learning trail and I found this video remarkably comprehensive in explaining in, laymans terms, many of the questions I needed answered and the most surprising thing of all was I was expecting to find at the end of the video some sort of promotion for this or that particular equipment or that you were an installer, but no, just putting this info out there without looking for anything in return, quite a revelation in todays society, so again many thanks for your time and effort. best regards
Thanks Quintin - yeah, my driver for making the videos was primarily all about saving people tons of time wading through the minefield of information (and misinformation) about solar technology. If I can make any money on ad revenue etc. then that will go towards improving my recording setup (which is currently very basic). Feedback like this really makes it all worthwhile, so thank you for taking the time to comment! ❤️
Gary - the man of my dreams :). We had solar installed about a decade ago by a company that has subsequently gone out of business (and sold our contact details so we have been regularly approached by other companies ever since). I wish I had seen your videos back then. We had no explanation of how our system worked and how to maximise our use of it, so haven't really been using it well. We've also had a few blips - mostly with the Solar I-boost diverter - and found it stupidly hard to find help. Thanks for your empowering and professional video. Really good to see that not everyone in this field is a cowboy!
Hi Clare, I wish I had got into Solar years before as well! Thanks for the very kind words 😀 I’ll keep the videos coming…
Thanks Gary. I'd like to point out one possibly helpful option -- at least here in the US. I used a Solar Co-op -- specifically Solar United Neighbors. They assembled a group of about 50 potential buyers in my city and put out a standardized RFP. We received 6 bids, which our selection committee reviewed in detail. Each installer quotes a sort of 'menu' panel/inverter/battery options, plus a schedule of possible additions (eg: long wire runs, warranty enhancements, etc). It even got into the weeds on such topics as diversity in hiring practices and community philanthropy. We had two experts from the Co-op help us evaluate the bids. It was a VERY informative process for those of us who volunteered for the selection committee. The selected vendor then visited each group member and prepared a custom proposal. The co-op experts checked the proposals to ensure that they conformed to the agreed group pricing and terms.
The approach might not result in the absolute rock-bottom deal, but I think it's probably a better deal than 95% of us would have negotiated individually. And each group member is completely free to back out at any time before they sign their individual contract. Those that walked away did so with the group's negotiated price menu in hand.
Hi Barry, thanks for taking the time to comment - that’s a great outcome and I’d like to see other communities doing the same! 😀
The most informative, clear and succinct video on Solar power I have seen. Well done Gary.
Thanks very much for this great feedback! :-)
Highly informative, communicated very well in a very easy to understand language. Well done and thank you Gary.
That's praise indeed - thank you! And you're most welcome :-)
This is very comprehensive..thank you for all the effort you've put into making this video. I've finally understood the difference between AC coupled and DC coupled!
Hi Afnan, it was all my pleasure! People have told me that I'm very good at explaining complex topics in a simple way (one of the reasons I started making these videos in fact), and so I'm very happy to hear my work has helped you too :-)
@@GaryDoesSolar Helped me too! Thanks Gary
Wow. The perfect balance of simple and detailed.
Ive done a fair bit off research and was really impressed with what ISNT in the video.
Youre managed to include all the end steps of my research with out all the confusing intermediate knowledge to get there.
Ok, that's praise indeed! Thank you, Simon :-)
I've been watching videos all day on this subject and FINALLY, someone who's explained clearly and concisely, thank you so much for making this video
Hi Darren, I'm well chuffed that I've been able to help you understand solar! It's certainly a minefield topic. Thank you for watching - and I'll keep the videos coming! :-)
Gary, being in the process of "going solar" and getting quotes, I've found your video most helpful in some respects so great thanks for that. I think I prefer the idea of microinverters with an AC coupled battery (despite the potential power losses), i'm not sure the price difference from a string inverter is so pronounced anymore, particularly a string inverter with optimizers and most microinverters have a 25 year guarantee nowadays (Enphase) versus a string inverters 10 year to allay fears of inaccessible repairs. I presume this means peak power usage (without grid) is limited to ARRAY + BATTERY in daytime and BATTERY alone in the evenings. I noted the batteries in my quotes, (Give Energy, Solax, Alpha Smile B3) only have a maximum charge/discharge rate of 2.68 Kw. If my house is using (TV-300, Microwave-1000, Fridge-200, WIne Cooler-100, Lights - 150, PC-150) and I put the kettle on at 3000, will that switch seamlessly to drawing from the grid or am I likely to experience difficulties with appliances? I suspect I may be getting mixed up with off grid systems there? Do you see that level of battery discharge rate as a problem if one is desperate to not draw from the grid if possible? Are discharge rates of that magnitude standard across the industry or can you get larger, in general those figures don't appear to be a readily available from an internet search although I can find Tesla Powewall is 5Kw surging to 7.5Kw? I suspect I will be more conscious of using other high power appliances during daytime if possible but I do enjoy a cup of tea in the evening! Thanks again.
You'll find that your solar and battery system will seamlessly provide electricity to your appliances both with and without any grid requirement. And I don't know if you read about the latest Tesla Powerwall 3, but it's got a 11kW discharge rate, so no worries (at all) You'll be able to have that cup of tea and not draw anything from the grid :-)
I have Gary and it has a lovely £11,500 price tag and a waiting list over a year long when it eventually gets here so I'm priced right out of that one. I'm thinking about 2 x SolaX 5.8 LFP offering, I believe I've read that their lower end power output is increased if 2 batteries are wired in series together as master and slave but not sure if that's true, do you know?@@GaryDoesSolar
Buying solar this year, this info just armed me for my upcoming quotes. You’ve earned my sub, even if I never need your videos again.
That’s praise indeed - thank you! I hope through these quotations you get the great setup for a great price 👍🏻
The best material about solar panels in RUclips. Very informative. Thanks Gary
Thanks very much for the great feedback. I'll keep the videos coming :-)
A good example of a no bs video about solar, you covered all areas without getting nerdy. thanks a lot for sharing from Mexico
Hi Leander, thank you for this feedback - it means a lot to me! Glad you're enjoying the videos
Fantastic video. This should be highlighted as the first video to watch, as it explains so much stuff. Thanks, Gary!
Hi Steven, that's high praise indeed - thank you! I'll look into that... :-)
Your video was a great insight into how solar works and it's helped me to understand how I will benefit from the installation. Thank you.
Cheers Stuart - that’s great feedback! 🙏
As an interested party, in this subject, may I comment positively on your excellent video. Great!
Hi Robert, thank for taking the time to comment. You are most welcome! I’ll keep the videos coming 👍🏻
Am just looking at going solar and this video has been extremely useful. Many thanks for going to the trouble of putting this information together, it must have been a lot of work.
You're most welcome, Ian. Yeah, it was quite a few hours to put it together, but comments like this make it all worthwhile :-) Good luck with your solar journey!
@@GaryDoesSolar Have a survey appointment booked for early Nov, thanks to your videos I’ll be in a position where I know what questions to ask. Was already told the earliest I can get an installation would be 6-7 months away due to shortage of panels and batteries etc so plenty of time to do further research. Thanks again for the information, extremely useful. Have liked and subscribed 👍 Cheers.
Excellent guide in simple language, think we are on-track with our installer so far!
That’s great to hear, Mike! Thank you 🙏
A great video! It deals with many fundamental concepts that I could not find on other solar-power channels. Everything is relevant, it is well explained. Thank you!
That's really kind of you to say, Niko - thank you! Please spread the word :-)
Please, please, please keep the videos coming Gary. They are by far the best I've seen with regards to learning as much as possible about solar energy. I'm currently trying to find a sales role with a company but often they are just interested with people who have experience. Well I don't. although I have been involved with sales and marketing all my life but want now a new challenge. Maybe one of your subscribers might be able to point me in the right direction. Thanks again......
Thanks Keith - I’ll keep the videos coming. And hopefully someone will read your comment and contact you. Good luck with your career plans! 👍🏻
Hi, Gary. I am retired and moved from USA to the Philippines. Built a new house about 18 months ago. Regretably, I didn't give solar power a thought at the time. After about a year of experiencing what I thought were excessive monthy power bills ( USD $150 - $175), then it dawned on me that I should be using this tropical sunshine to my advantage. I am an
I am an absolute novice when it comes to solar power. So, I started checking things out on RUclips. Your site was about the fourth one I viewed. I wanted to let you know that I found your presentation very easy to follow and understand. I am looking forward to watching the rest of your videos and learning a more about solar power options. Keep up the good work, Gary.
Thanks Robert - great that you found my videos! I’m sure you won’t be a novice for long either 😎 Sounds like your move from USA to The Philippines went well - I wish you the very best, and I’ll try to keep the videos coming! 👍🏻
@@GaryDoesSolar Wow! Thanks so much for the quick reponse. I am really impressed. YOU ARE THE REAL DEAL, MATE!. So far, you are the only site to respond to my messages.
It took a couple of years of researching the Philippines before l made the move. So far, regrets! The only regret is that I did not come when I was a little younger. Been here a little over 8 years already. I have wonderful wife of 8 yrs. We are in the process of adopting a 1 yr old Philippine boy. A new challenge my life.
I am looking forward to seeing more of your videos. Take good care!
I'm been doing a lot of research before taking the plunge. It's reassuring to have this information!
Thank you! And all the best in your solar journey! 😀👍🏻
Well worth a watch and has given me some use full tips I am struggling to find a decent solar installer plenty of people who'll txt me a price but nothing in righting and other companies just turn up and no quotation, seems to me its a mine field just trying to find an installer. when I do ill refer to your video.
Thanks Bob - yeah, because a lot of people are trying to get solar installed, demand is very high against the number of installers available. This situation might exist for another year or so before things calm down, unfortunately. Hope you are able to find a good installer soon!
Professor Gary! A really valuable video, your delivery is excellent. Thank you.
Thanks and you’re most welcome! 😀😀😀
Great video thanks.
I've always understood solar but never quite understood the various power ratings etc of the inverters, but this video is perfectly simplified and now I understand them too! Many thanks.
Great to hear that my videos are helping you with your understanding! Thanks for letting me know :-)
good brief of the battery hookup methods - dc coupled or ac coupled
Thanks Dougie! :-)
From one Gary to another, thank you so much for your impartial and clear advice. I thought I knew enough but I quickly discovered that wasn't the case! Your advice at the end about choosing an installer is top notch, all very valuable tips.
I consume 20,000 kWh per year but no more than 20 panels can fit on my roof, so only 25% of the daily demand can be met by solar during the summer months. Less than 10% can be met during the winter months. Solar does seem rather pathetic in this light (pun!) but I don't know what else to do given that the Oct 2022 price increase will shove my bill up to £9K per year which pushes me closer into the growing "heat or eat" group.
Hi Gary, there are not enough of us Gary’s 🤣
Wow - 20MWh per annum! That’s about 3x my own use. Ok, so for my own (impending) installation, I’m looking at 19 x 400W panels and 2x9.5kWh batteries. This should cover my daily use of between 10-30kWh (the days with higher usage is mainly washing machines and tumble dryers - which could be load shifted).
I’m building a spreadsheet for my next video which allows you try out various solar/battery configurations. I’m not sure it can solve your situation, but I’d be more than happy to send you a copy in advance for you to play around with? Just let me know…
Excellent video the link to the EU website was just what I was looking for to get a handle on what output I could expect from various options.
Cheers Peter, you might also like this utility I made then: garydoessolar.com/utilities/dailymodellingutility/
Great video again, Gary. Something I've found when shopping for quotes is that MCS is now rivalled by FlexiOrb accreditation. They are the same standards, but I've been told by an installer that FlexiOrb charge an annual rate compared to MCS charging per install, so some installers prefer one over the other depending on volume. Not sure of the details on that as it's just what I've heard from a FlexiOrb-accredited installer. Perhaps unsurprisingly, all the MCS-accredited ones I've spoken to insist that MCS is the only accreditation worth anything.
Crucially, Energy suppliers such as Octopus, British Gas, EON, Scottish Power, OVO and UW are now accepting FlexiOrb accreditation for SEG tariffs. Might be worth an update to the description, or even a short video explaining the new accreditation and certification standards. Cheers!
Thanks - this is a good point. And a welcome situation because it’s typically always detrimental to the consumer if there is a gate controlled by a single supplier (in this case, MCS). Competition drives better quality and price.
Great video. As I’m having solar installed later this year, it really helped answer some questions I didn’t know I had 😂. Thanks
That's so great to hear - thanks for taking the time to let me know :-)
And all the best with your solar journey!
Wise man’s words for all, thank you .
Thanks Tim! :-)
For this 2nd "Primer Video" you have indeed covered the major basic points which took me about 5 days to learn from scratch. Budget will always govern most installations (but shouldn't) as in my case, the front of my house is SW facing so I have 3 roof areas pointing in different directions all with clear views and good sunlight in morning/ afternoon/ evening that can be used (I'm changing my roof so going for in-roof system) and that puts me into optimised/ micro inverter category. Jury is still out on having a battery due to space (pointless having a small one) and Im not having it on view outside as thieves can easily isolate and steal them.
Great to hear that I’m covering the right topics 😀 your house situation does sound like a challenge, but from what you’re saying, you’ve got a promising solution! In-roof Solar sounds like a good plan - I think I’d probably do the same, but I’ve got quite a few velux windows to skirt around. I totally agree with you on the battery front - the biggest you can afford is likely the best way, and installing it inside the house would certainly not give any passer by reason to steal it! Hope all goes well with your setup, and if there are any topics you’d like me to consider for future videos, just let me know 👍🏻
I'm thinking about putting my battery (if I get one) in the unused chimney! I live in a Victorian terraced house so no real space to use but both chimneys are not used and the batteries are IP certified so should be fine in the chimney! Hopefully?
Thanks Gary I’m looking and you’ve given me so much info…always say INFORMATION IS KEY…nothing worse than looking for something and not knowing a bit info and being pushed into buying what you don’t want or need ..
Hi Darren, thanks for the great feedback. I totally agree with you and hope my videos are 100% information, 0% filler 😀
I’m really surprised that there hasn’t been more talk of this on the tv..and I know you can get grants if your on some sort of benefits unlike most people out there ..
But there needs to be a option or insensitive for working people ..
Totally agree, and I’m thinking that with energy now being on the forefront of everyone’s (including the government’s) mind, we can expect to see some positive changes in policy 👍🏻
Special thanks for this video - we are at the beginning of the process so getting some coaching and advice on system design and installers is timely.
You're very welcome, Rick - and all the best with your solar journey. I have other videos looking into the different aspects, which may be of help too :-)
Your videos are brilliant, so detailed, I believe ,after watching anything that people are unsure of are definitely made a lot clearer, your knowledge is priceless, you should start up your own solar company, you have the know how , you just need to employ people to install that
With reference to quotes I’ve had a few and except for one ,they seem to quote for 4kw ,I suspect it’s because it’s the easiest option
Hiya. Thanks for the very kind words. My main activities are in mobile space, would love to have more time so I could get more involved in the energy sector, as it's such an interesting space! If you're in the UK, then the 4kW quotes are a lot easier for installers as they only require G98 certification, which is far easier to complete than G99...
Excellent explanation, answered questions that other videos left me scratching my head!
Thanks Dave - that’s so great to hear 😀👍🏻
A little correction, microinverters should not be the more expensive option, it should be the same as a system that use optimizers, let says is buy a 10kw String inverter for £2.000 (SolarEdge) and you install 27 panels (370w each) for a 9,9kW system array, when you divide 2.000/27= $75, then an optimizer will cost you around $60 (or more) each, the total is around £135+ per panel, which is very similar to a microinverter like Enphase IQ7A, £160 each (and now cheaper with the new IQ8 series).
This is just an example, the String Inverter + Optimizers is more expensive when you install a smaller array system, because a 5kW won't cost you half price of a 10kW S. Inverter, so the cost per panel is a little higher, and keep in mind when you use that setup, you have 3 points of failure (panel/optimizer/inverter), while with a microinverter you only have 2, besides Enphase provide a 25 years of warranty.
Hi Federico, thanks for the extra analysis. Great to see that microinverters fare better against other solutions than I thought :-)
Great video. Will watch again when I do the cost calculation.
Great stuff! My next video (out in a week or two) will cover cost calculations and the like
Best video for new solar costumes I have seen. Very good and practical advice. 👏 👏👏
You’re most welcome! Thanks for the kind words 😀👍🏻
Thank you Gary as this video is very helpful especially when like me knowing nothing about solar panels and batteries, can't thank you enough for your knowledge on this subject as its going to be a BIG help in knowing the right questions to ask .
Thanks Susan - it took me many, many hours to make these videos and your feedback alone has made it all worthwhile. Good luck with your solar journey! 😀
Morning Gary. Well that an excellent explanation you have given us, will pass this video on to someone who is considering this. I have had solar for 7 years best thing we ever did, got our money back in under 5 years, now charging two cars and heating / cooling our house via Solaredge and Solax battery. Thanks Bob Blood Kent England.
Thanks for the great feedback, Bob! I'm very jealous because I'm still waiting to get my installation done (long story about a supplier that let me down) and you've not only got your installation, but you're already past the breakeven point! Well done! Are you considering any additional components or do you think your system is complete now?
Clear and concise, thank you for making this very useful video. At least now I know what are the important questions to ask when getting a quotation.
Hi Ken, you're most welcome. Happy to help you out! :-)
Great video and helpful - Only one thing about Companies House - Its different in Scotland and a company is not required to be registered with CH
Thanks Craig. Now, with regard to Scottish companies - are you sure they don't require to be registered to Companies House? See this link: www.mygov.scot/contact-companies-house
Hi Gary - just looking through more of your videos and getting the info for micro inverters - all great info - I need to store on DC batteries too so that makes it a bit more of an issue with another standalone inverter - I'll get there ....... As far as companies house - every LTD company needs registered and I was told every VAT registered business in England needs to register but for some reason not Scotland - My company for 12 years has not needed to register and I am VAT registered (So - many smaller businesses may chose not to register - most of the bigger businesses are LTD and there for find it compulsory) @@GaryDoesSolar
@@craigstewart1878 Ah ok - I was referring to LTD companies - they need to be registered. If you're working as a sole trader or partnership, maybe you don't need to register.
Top quality video, thank you for this one, Gary.
You’re most welcome - thanks for the great feedback!
Hi Gary. Like many I imagine, I am new to solar prompted by the expected increase in electricity and gas bills. I've watched umpteen videos and read tens of thousands of words. I could have saved myself loads of time and effort and just watched your videos instead. They provide clarity in the midst of confusion. Many thanks for taking the time to do this.
Hi Gordon, you're very welcome! This was my aim, so it's great to get feedback like this :-)
Supremely clear and comprehensive. Thank you indeed!!
Really great feedback - thank you! I’ll keep the videos coming… 😀👍🏻
Hello Gary, thank you for such a clear video. Until I discovered it I had been floundering around in the dark. I recently 'expressed an interest in a local authority group buying scheme. The winning bid by the solar/battery provider will be the cheapest I suspect. My concern with this is that I would have limited input in what they want to supply to me (solar panels/inverter/battery). You have given me some idea of how to consider whether their offering is right for me. Exactly what I needed at the right time.
My pleasure, Jane - very happy to have helped you 😀 and all the best with your solar journey 👍🏻
Really helpful and thought- provoking for me.
The other topics I'd love to know more about are
- 'add-on' roof panels vs built-in (I'm needing to grt some roof work done as my tiled roof in old and not felted). I wonder if combining the work would be better and having 'inbuilt' panels ?
- what other mods are needed to the house ? Eg will in need a new consumer unit as it's adding a new circuit? (And plastic ones now verboten on upgrades (even though 90% of us have them)
- where can and can't the equipment (inverter, battery etc) be located- my garage is detached and too far away)
- can solar set-ups be put on out-buildings and 'piped back' into the house ? (Eg my detached garage)
Thanks for the topic suggestions, Peter - I've made a note and will keep these in mind...
Comprehensive video. Regarding shading at the13.00 minute mark, there was no mention of module internal by pass diodes that help elevate power loss when shading occurs. This is an adequate solution more often than not so it is not always necessary to install optimisers to solve shading issues. Well presented video Gary, very good.
Hi Craig, thanks very much for the kind words. And yes - a good spot! As it happened, I wasn't aware of bypass diodes when I made the video. I thought I should investigate deeply when I had some comments about the claims of the optimiser/microinverter manufacturers. This resulted in a dedicated video on shading.
@@GaryDoesSolar I'll take a look Gary, good stuff
Thanks, Gary, really informative, we are just starting to gather the information we have a flat roof above our flats with E7 off-peak heating supply, so are looking at solar supply in the day and E7 charge of batteries at night. Thanks for your channel you have a great presentation and keep it simple.
Hi Stephen, thanks very much for your kind words - and I wish you the best with your solar/battery plans. I do like the fact that Economy 7 tariffs are coming back into fashion. If you're wish Octopus, you might also want to look at their new Flux tariff - I'm creating a video on that tariff at the moment...
Very useful, informative and professionally-produced video, Gary. Thanks so much. I've had a 3kw 12-panel system for 9 years now. It's great to have such a detailed explanation of what I have had running all this time and interesting to see how the hardware has changed over the years. Mine are discontinued 250w panels at 15.4% efficiency. Not great now but good at the time. Still, they'll last another 15 years so not worth changing them. Great advice on how to spot a dependable EV installer. I need one for support as my inverter is nearing the end of its expected life and my accredited supplier told me about the optimisers now available. They weren't included in my setup so I'm having them retrofitted. At least I now know, independently what they're for and how they work. I'll send them the link to this video so they can recommend it to their prospective and existing customers as a useful independent reference work. You should be mandatory viewing for everyone in the market for solar! Thanks so much!
Thanks Gary - that's very kind of you to say - and great that I've been able to add to your knowledge. I wish I'd got into solar 9 years ago like you did! :-)
@@GaryDoesSolar So G98 application is always acceptable and there is no rejection as it's less than 3.68Kw (AC-power) but there is chance of rejection in G99 , is that what you are saying ? Kindly guide in more detail please , thanks.
@@fahadmukhtar1124 That's correct, yes. And every DNO will have their own acceptance/rejection criteria for G99 applications.
@@GaryDoesSolar Thanks a lot for information !!!
I got a 55w panel on my east facing balkony. And, well it seems worth the price. Even with the ecoflow rover solar generator included. For the current price of electricity here. I may save its worth in a couple years already for the hours i get. In scandinavian summer where the sun never sets. Does not work in the evening. What i measured from the panel is under one amp of current, so two panels might get it to charge with that. I need to find proper places for the panels before i get another, so not happening too soon.
Has definitely been worth it for the exitement. I got it mainly out of interest rather than economics, but yea it sort of makes sense moneywise too.
Plus. The ecoflow is just about enough to keep my fridge running through a night of outage. Haven't tested that though, may need more startup watts..
Sounds like a great little setup. I can imagine you'll be wanting to expand it soon as well :-)
great video.your deep explaination just gave me a great knowledge and understanding about solar and it installation.watching you from ghana west africa
Fantastic to hear this feedback - thank you! :-) All the best!
Excellent content and presentation 👍👍👍
Thank you, Andrew! Great to get this feedback ❤️😀
Really useful video. What is apparent is that a large part of the cost involved is not related to physical equipment but to istallation costs and the overheads and marketing costs of the installing company. Then there are certification costs if you want the system to be connected to the grid.
I have been thinking about an alternative route; a DIY installation with no export to the grid.The only bit I haven't got my head around is connecting to the house that isn't Heath Robinson!! My House faces East West but I have a south facing shed and will soon have a carport with similar orientation and reckon between them they would support an array of about 4KW. DIY would cut the cost by around 40% or more. Even more if I built the battery myself.

Many thanks, David! So great to get feedback like this :-)
Thank you so much for sharing your knowledge, Gary. This is highly useful information for me!
You’re very welcome - so glad to have been able to help you out 😀👍🏻
Good summary and well worth watching for anyone to gain an understanding of the solar requirements initially - thank you Gary
Thanks very much for this feedback. This was my primary objective and so it’s great to hear that my efforts have been worthwhile ❤️👍🏻
Gary This is most honest and informative video about solar you will ever get. Thanks
Hi Saber, thanks very much! That’s praise indeed 😀👍🏻
This is awesome. So much information that no one else seems to know/share on their channels!
Thank you - that means a lot to me!
Loved your video, Gary! Could you please make a video on installation specific to using solar powered EV charger installation steps
Cheers! 😀 I’ll add to my list, but it’s getting to be a BIG list!
Great video Gary! Great to see you are still explaining complex things in a straight forward way! I've been on the solar journey for 2 years now and still learning!
Hey Mark! You found me on RUclips! Who'd have thought, eh? :-) Thanks for the kind words - great to hear I can still do it!
I'll text you early next week if that's ok. Would love to catch up with you :-)
Gary, For those in USA, or anyone else that can verify whether PVwatts is the only available tool for measuring each plane for rooftop mounted solar array? Thx 👍
Keep up the great attention to detail on the content🙌
Thanks for your very kind words about my videos! :-) Worth watching this video I made about Google's Solar API: ruclips.net/video/LFiV--uzjh8/видео.html
Thank you for producing an excellent video which I found to be very clear and simple to understand.
Like many others I am starting to think seriously about installing solar and your explanations have given me a basic grasp of the components used, their functions and various options. It will also enable me to have some rather more informed discussions with potential installers.
Thank you so much for this feedback, John. My next video on calculating the payback period should be ready in a week or so. Hope you enjoy!
thanks Gary , well done.
Cheers William - thanks for taking the time to watch :-)
Very informative and clear explanation helping very much with my research into solar pv options for our home. Thankyou - ‘A’ level physics just about starting to come back to me…..
Thanks Kirsty - very kind of you to say! My next video will likely be explaining some of the terms, e.g. kW, kWh, kWp, volts, amps, frequency etc.
Great video, after checking hundreds on them, well laid out with clear understandable information, please make more videos with info on your installation if you have one and how much electricity is generated from Nov to feb in uk thank you.
Thanks for the kind words. My own solar journey has been a nightmare. All being well, it’ll be installed in January. I’ll maybe make a video about it 👍🏻
Absolutely EXCELLENT detailed information. 👌
Thanks Tayari - great to hear! :-)
Excellent first two videos. Gary, hope you will do some more. . You are the right person , with the right channel at the right time to be offering potential individual household solutions on the energy crisis. Good luck with it
Hi Dennis, thanks very much - wow!
It's a lot of work, but if I can help even just a few people make the leap and cut their energy bills over time, I'll be well happy! Next video out very soon...
@@GaryDoesSolar Sounds good😀
Hi Gary, As with everyone else who've watched your videos, I am so grateful to you for providing this extremely well-presented information at exactly the right time for me. It was amazing that, as I watched, a question would come into my mind only for you to cover it almost immediately!
I'm on the brink of making the important decisions, so these videos are perfect. Thanks again.
Hi Phil, thanks for taking the time to make this comment - wow! I’m humbled. And glad to have got round to it all in time for you! 😀 I’ve just published my next video which you might find useful too 👍🏻
@@GaryDoesSolar Thanks Gary, I'll watch it now. Best wishes, Phil
lovely, mate, extremely concise and helpful; many thanks.
Thanks for the great feedback - much appreciated! :-)
One of the best vids I've seen regarding solar ;) I've actually learned something even after watching similar vids for months
That is so great to hear, Vlad! Thank you 🙏 😀
Brilliant video, could you do a video on the survey process and the software used by installers to build the system on your roof? Like open solar and easy pv etc..
Thanks for the great feedback! I cover a little on OpenPV in this video, if you’re interested: ruclips.net/video/MdpQci4vTLU/видео.html
Gary, I've been looking for a vid that brings together all of the key points, this is it. Comprehensive and with appropriate level of detail I have all of the building blocks to enable me to give my solar project the green light.
Many thanks
That's great news, David! Very happy to have helped you out on your solar journey :-)
Cracking video Gary. You've explained this so clearly. Now I know what to ask when the solar guy comes around next week.
Thanks Paul - I'm very glad to help you out :-)
Thank you Gary!
My pleasure, Kathy - glad you found the video useful 😀
Thank you Gary, this is the most basic and very very useful video I have found online for installing solar panel. Now I know what to look for and what questions to ask when I go ahead with my project. Thanks ever so much. I have given you a thumbs up and subscribed.
Thank you so much for this great feedback! :-)
Very useful information. Thanks for sharing, Gary
My pleasure! Thanks for watching :-)
Gary! What a sensational video, love seeing a thought leader break down solar and explain it as if we were all 5 years old. This is the exact type of content that needs to be readily available before people decide to invest in solar. I would love to hear your thoughts on some brand-new software we've just created. Gary, could you reach out to me as I have an opportunity for you which I think you'll be very excited about.
Hi Harry, thanks for the kind words. Sorry though, I’m not in the market for lead generation software - that’s not what my channel is about. All the best as you market it to others.
@@GaryDoesSolar Thanks Gary, apologies, I am not trying to sell you software. I wanted to gather your feedback on it seeing as you're a thought leader. Let me know if you'd like to hear a bit more to see if it fits with your values.
Your videos are amazing! I love the practical, understandable advice.
Thank you for the very kind words, Jason 😀👍🏻
Thanks for this video and especially the calculator link! Very helpful.
My pleasure, Bruce - thanks for watching! :-)
These videos are outstanding! Many thanks
Hi Mike, that’s high praise - thank you! 🙏 I’ll keep the videos coming…
Magnificent video. Excellent explanation.
That's very kind of you to say - thank you! :-)
Brilliant videos Gary. Really informative and helping me make an informed choice. Can't wait for the next video. Thanks Mike
It took quite a few hours to put it all together (really, rally hard work) but comments like this make it all worthwhile - thanks Mike! :-) All the best with your solar journey - I'd love to hear how you get on. My own journey is actually only just starting...
@@GaryDoesSolar your research is something I would of done and spent weeks and weeks doing, so really appreciated. Yes when I do go ahead I let you know 👍
Another really helpful video. Thanks for taking the time to give us such useful information.
You’re most welcome, Charlotte. I’m really happy to hear that you’re getting a lot from the videos 😀 I’ll keep them coming!
Black Belt Barrister on RUclips nearly got his finger burnt chosing a roof panel solar system.
Well worth a visit, especially if you're considering a home presentation.
The same applies if you're considering double glazing windows.
Yeah, if he can get caught out, then pretty much anyone can. I'm hoping to do my part to help with this in time...
Thank you sir for this very information and thorough presentation on Solar Energy Generation. You covered almost everything in professional details. I liked your channel and I appreciate your sharing with the general public. Thank you very much.
You are most welcome, Shaider 🙏 thanks for watching 👍🏻
superb attention to detail Gary and another very well explained video, thank you!
Hi David, thanks very kind of you to say - I do pride myself on being detailed :-)
Great video. One question though and not covered is the integration of battery storage in a grid tied existing system on a FIT. I imagine an AC coupled inverter is the only choice unless the existing string inverter is swapped out for a hybrid and then, metering will need to be checked so as not to effect the FIT readings.
Now, I don't have a FiT setup myself, so I'm only going on what I've heard from others. My understanding is that so long as you don't alter your FiT setup (e.g. do not swap out your inverter for another), then provided to you inform the FiT scheme of the changes (specifically only additions) you're making to your home, everything should be fine.
For example, you can add a battery, but it must be AC-coupled with it's own inverter (built-in or otherwise). You can also add more panels, but they must be on a separate inverter to the existing panels.
very informative video thanks i can now make informed decisions about solar
Great stuff 👍🏻 😀
Excellent, thank you for the video, I thought it was very informative.
You're very welcome, and thanks for taking the time to let me know! :-)
