- In this video we guide you through the smallest solar PV system we have ever completed!
During this video we go through how we have installed this in roof Viridian Solar PV system with SolarEdge optimisation and monitoring.
Solar doesn't always have to be installed on a large scale to make a difference. This garage is a perfect little spot for some solar to help remove the base consumption from this house.

This panel can put out close to 100 watts ruclips.net/user/postUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.
So jealous. I've just had solar panels installed along with a new roof - all contractors just didn't care and have just thrown the lot up. Love people who offer attention to detail and neatness
One of the most rounded descriptions of a solar system, I’ve found, much appreciated.
Thanks very much!
I was watching this video to ask about mounting board, perfect timing. Thank you 😁
😂
Great presentation and also great work. Your install looked very neat and professional and the builders who built the garage did a good job too. Well done.
Thank you very much!
This is great and shows that matching PV size to house use works best. Too many installers throw as much on the roof as possible without the consideration for capital cost and daily usage.
Thanks for watching!
Very interesting, thanks for that! I have a small but unobstructed south-facing roof on a terraced property that i think i could squeeze five, maybe six panels onto, so it's reassuring to hear about similar-sized installs that can make a difference.
Yes sounds like this setup would be a good one for you
Great little system well explained 👍 getting the kit is the only problem for the rest of the year😀
Thanks very much. Yes stock is a pain at the minute
Excellent. I am watching for tips as I am going to fit myself but I must admit if I was looking for someone to supply and fit you come across great i would not hesitate to use you👍
Thanks very much for the comment. I hope your install goes well
Beautiful job lads - looks the business.
Thanks very much!
Excellent video, cheers lads 👍
Thanks!
Cracking video again 🔥🔥
Thanks!
great video keep them coming
Thank you very much!
Great job.
Thanks!
Great video, great explanation, would love to get into this type of work myself
Thanks very much!
Great video, all the extra explanation on the build is appreciated. In the video I also noticed that the SolarEdge modbus has to be within a certain range of the Inverter, in this case it uses the RS-485 standard, which in it's self is not bad, but for case where there is either zero cabling or distance is still an issue... it appears this can easily be transported over regular Ethernet infrastructure with converters... since the majority of these installs also require Ethernet links to the internet, it stands to reason this may help solve communications issues where all the kit does not happen to be in the same place.
Thanks Ben
Great video and explanations
Thank you!
Superb video
Thanks Mike!
Bet they'll want a bigger system in the future though 🤦♂great video though Sam 👌
Great video again and very informative. Where is the best place to get yourself the knowledge you need to start selling and installing Solar PV
I like that 1.5KW SolarEdge.....👍👍👍👍👍
It’s great!
@@OvalRenewables how much is the cost/price of that 1.5KW Solaredge?
@@rds0009 I've seen the inverter with optimiser online for around £750
Nice job @oval renewables
Thank you!
Can you use multiples of that optimiser on a larger setup, I like the idea of having the optimiser in the roof for maintenance?
Loving the videos thanks.
I have dormer windows on a south facing roof so have limited roof area for panels. I had 6 x 375watt panels fitted plus a 5 kw Puredrive battery. In 6 months since install made 1700kW. 700kW has come from the battery storage. I am sure I will out perform the quoted generation estimate 2250kW. So far the panels are delivering 60% of house usage. I have a 2000 gallon pond that use 2.5 to 3 kW a day. Very happy with results. Pay back will be about 5 years at 52p electricity fixed rate
Great figures!
Great video and really helpful as I'm looking to install an in-roof system on my own property. Just wanted to know how you were getting your cables into the loft to each optimiser? We have used Dektite Multicable lead flashing kits to bring cables through, but doing this for each panel seems a faff so wondered how you did this as its not in the video, but totally agree that having the optimisers on the inside makes life much easier should they fail.
Love your vids. Been trying to find out how the power from the solar is controlled to supply the house power over the grid, assuming it’s voltage control?
The amount of arguements I've had over the years regarding the need for a DC isolator is mad, too many seem to think that the DC switch on the inverter is enough, no way I'm having that.
Hi, I have an older system which has four sections of panels (250W) 2x 3 & 2 x 2, 10 in total could I have an optimiser fitted, I have two inverters a Solax and a Solis any ideas please.
my yearly usage is around 5500,6000kwh, so how big of a system would i need to completely remove this?
Would love to know what sort of money this would be with battery storage?
What suction cups do you use?
Hello What size are those panels please and where to get them ? I got excited at a small off grid system from my garage roof.Hit full stop and market silence : Can you advise any information on a manual grid/solar power transfer switch Understood it was possible to select some existing house circuits: Switch them to solar as and when ? Many commercial manual power transfer devices in USA but UK appears silent ? Ms O
What other in roof systems would you recommend Sam?
How much was this install roughly as I’m looking at almost an identical install to this?
Use the inline trays,the roof panels sit on them,then flashings on the side, you can see some fixings but doesnt look offensive,go for a tesla battery power bank 2, and with a 4kw solar array,you can qualify for 12p per kwh import and export
That is certainly one option, however I prefer this system over the GSE plastic trays.
Really beautiful attention to aesthetics here! Any concern on heat dissipation? Maybe not an issue in the UK, but it's come to my understanding that heat reduces cell efficiency. Would be cool, ( pun intended) if those channels created by the lumber strips underneath could act as an airflow somehow.
Thanks very much, there will be a slight loss on the hottest days but not anything too major.
Nice clear description of the instal, is there a video of how a diverter is installed
Thanks for watching! We are waiting on stock for the SE diverter but will be doing one when we get them. 👍
Smart. As its effectively a new build you save on the cost of tiling underneath the PV modules. #solar
And as of now building materials are so expensive I think the panels are cheaper for coverage than the tiles
Yes it helps to reduce the cost in total when looking at buying roofing materials
@@haldo691 JUst need to be mindful that if a panel does go "phut" in a few years time - will replacement panels (the company that produced them) still be available (exist).
Great video 👍 quick question is there a reason why the optimizer can't be installed next to the inverter like would it be possible to extend the solar panel cables or is there a reason against this just curious . Thanks
We do this sometimes when it’s an inroof system that has a good loft. You can’t do this on a normal system as we can’t extend the connection between the panel and optimiser.
Can't beleive you are asked where you buy the document holders. Seriously, if people can't work something like that out they shouldn't leave the house in the morning unattended...Great content as usual! Lovely little job
😂😂
Can’t believe that you don’t know how to spell believe 🤷🏻♂️
@@Haymarket47 damn these sausage fingas
Given how unreliable SE optimisers are (I've got about 20 warranty replacements sat here waiting to be fitted), putting the single optimiser somewhere accessible seems like a good idea.
Although I can't help feeling you might have been better off just fitting a regular string inverter!
20% of our systems and 90% of our problems are SE. An entirely functional SE system does perform a percent or two better than a non optimised system but most of our systems have faults. Something like 1 optimiser failure per 50kW per year.
I've got a box of failed optimisers awaiting replacement too. Really not delighted with them.
This is quite surprising, I dont believe we have ever had a SE optimiser fail yet! However I am aware that one day it will happen.
Well when they are in the overcast weather 90% of their life, they last a long time!
SE stuff is great when it works but like you say it's the worst when it goes wrong and it does.
Hi, love your content! A comment though about the Viridian system. I’m looking at this myself but I’m staggered at the cost of the flashings. They’re up there with the price of the panels themselves, which considering the materials and technology of each, seems nothing less than a rip off. I’ve made the same comment on Viridian’s own channel, but funnily enough, they haven’t addressed it. Any thoughts?
Hi Paul, thanks for the message. We aren't directly affiliated with any brand so happy to comment on things like this. The viridian system is not the cheapest system on the market. However it is the best looking in roof system in our opinion, this does mean the system is sold at a premium price. A cheaper system would be the GSE option.
@@OvalRenewables Thanks for your reply! I agree that it looks the business but still contend that the price of the flashings compared to the panels themselves is still taking the mick. I suppose, like everything else in this world, it's going to take volume and competition to force them to drive their price down. ATB.
It would be worth getting a battery and charging at low EV night time tariffs surely regardless of the small solar PV.
A small project of 5 panels of 340w to help remove the basic needs?
I live completely off-grid and run my house and small business on 1200w of solar.
Sometimes it is not just the supply side that needs attention. The best energy saved it the energy not consumed.
Absolutely
Can the Solar Edge ModBus be installed as an independent energy monitor ahead of the installation of a P.V. system or does it need the connection of the inverter to work?
It would have to be installed as part of a full system as it links to the inverter to send the info to the portal 👍
Great installation Sam . I have 10 x 410 solar panels with 3.68 SolarEdge system recently fitted and they never advised me about a Modbus meter. I would like to update to include a Modbus is this an easy/simple upgrade to do? I am about to have my Consumer unit replaced (RCBO's & SPD) by my local Electrician and was wondering if the Modbus could be fitted on the din rails within the Consumer unit? ( is this allowed? ) of course I would ensure there was space for this to be installed. many thanks.
Thank you very much, we find that the Modbus doesn't sit too well in a DB. You are better off mounting it in an adaptable box next to the DB. There are some other videos on our channel that show this setup. Your electrician could install the wiring but I would advise you get a trained SolarEdge engineer to carry out the programming and commissioning.
@@OvalRenewables Many thank Sam
Also have a look at the Shelly EM unit. Compare the functionality & costs. Have a look at this UTube Vid. ruclips.net/video/pgJDla8sWiw/видео.html
Great Content - Quality workmanship also.
Am I correct in thinking that where the panels are there are no roof-tiles underneath?
It's just battens and Felt/membrane to the gutters - with tiles put around the edges against the Solar panels?
Thanks
Terry
Yes the panels don't have tiles underneath so you also save on buying tiles
@@haldo691 Thanks - Looking at replacing my roof next year from old red tiles to new black/grey slate - This looks like a perfect solution and as you say, would save on some costs.
Yes as the other comment mentions it saves on roof tiles
I have replaced loads of the lower flashings as they slip out because not fixings.
Add more silicon CT1 under the lower flashings. Good luck guys.
Thanks for the tip
Thanks for all the info. Can you fit these panels on top of existing roof tiles?
No problem. They are designed to go in roof so your tiles would have to be removed for these ones to fit.
@@OvalRenewables thanks for the reply.
I wish you did Lancashire !
We do! We will be reopening soon
I've been looking to get a small system on my garage roof East/West with the very same solaredge inverter probably 7 panels. What is the orientation of this roof..
Cool, I think it was south
I’ve got a garage with a supply to it and board ,do i need another cable going back to the house .?
Hi there it depends on the size of the cable but possibly if it’s a big system and a small cable. We also need to make sure the volt drop calculations work out. Best thing to do is to arrange a survey
I'm considering solar panels but I live in an end terrace house with minimal internal space other than the loft,roof is south east facing. Would a system be worth installing, are there grants available?🤔 Thanks👍
Hi Rob. It depends on the size of the roof but anything that you install will make a difference!
The panels are retained on the sides, but how do you stop them from sliding down?
If you have another watch there are also clips at the top and bottom. 10 fixings per panels
Interesting that the big disconnector/isolator is in the garage. Building regulations here require them to be outside and clearly labelled, so the fire brigade can easily turn them off for extra safety in case of fire.
Is this in America?
@@OvalRenewables No in Finland. The actual requirement is a well indicated and freely accessible location for emergency services and power companies. Which in practice means it gets installed on an outside wall (as otherwise you need to leave the door unlocked).
Great video!!! The excess Energy that goes back to the grip!! Is It just lost energy to the home ?? Or does it come off on the energy you then use from the grid?
Thanks
If the customer is registered for SEG payments they will be paid for it but depending on supplier could be as little as 4p pkwh
Yes the other comment is correct. The customer is registered for SEG payments but is only receiving around 4p per Kwh
If you have old type meter (mechanical) you are better off
@@OvalRenewables don't know how they get away with paying so little my average was 30p pkwh last month on octopus agile outgoing
Great video. What would the basic cost of this system of 5 panel's?
I believe this one was about 3k
What likey cost of rail mounted 5 kW set
Very interesting, cheers for this - just wondering but I've heard from people with less experience and knowledge than you, that recessed panels can be at risk of overheating and producing less power. Is there any truth in that? I'm more keen on recessed personally, less space for birds and insects to hide, and where a new roof is being built, no pointless tiles. Of course that could be a downer if for some reason the panels are removed. Cheers 👍
Thanks for the comment. You do sacrifice a slight loss on the hottest days due to airflow but for me the look of them outweighs the losses.
@@OvalRenewables You're very welcome. Thanks for answering, I'd have to agree with you, especially considering how many actual hot days we get. All the best
Yo your flying half done lol
Haha the trousers broke that day!
21:32 Wonky mounting 🤮 I can’t unsee that!
Does the modbus have to be hardwired to the inverter? Looking at a similar install but running a new cat6 would be challenging...
Thanks for the comment. I believe SE have a new meter that is available that can connect wirelessly. We haven't fitted any yet so can't say for sure at this point.
@@OvalRenewables interesting... Do you have a part number?
Modbus is a protocol over RS485 rather than an item. The energy meter in this video uses Modbus, but there is no wireless version yet.
If the price/kwh for electricity goes to 50p and export is 5-7p then it would make sense to add a battery. That would seem to be on the AC side since the inverter does not have a battery input or when the customer gets their EV to really make use of excess solar during the middle of the day.
Yes as the import rate increases during the day then a battery starts to make more sense as it can be charged during the night.
That ship has sailed. The new standard tariff is already 50p per KW/h (Varies by region from ~47p to 52p, but average of 50p). However, based on continually rising wholesale prices, some analysts are predicting it could hit ~£1 per KW/h by mid 2023. Which is bonkers.
@@Haawser Lets hope Lizz has got a solution.
@@Haawser Far from it, its curently capped at 28.34p kw/hr, next month October goes UP to 34p kw/hr. Adds about £209 a year to an above average user. Then knock off the £400 handout, most will be £190 better off than at current.
I wouldnt listen to the scaremongering media, it sells a story - without a story no income!
@@jhareng The cost WAS going to be 50p per KW/h, but I wrote that before the govt stepped in. If they hadn't the £1 per KWh was also very likely.
Hello, I am looking to buy used solar panels in a very large quantities, do you know where I can get them in Australia?
Sorry unfortuanlty not
Just watched a Vlog from Blackbeltbarister, think he needs your expert help!
haha I haven't seen it.
I take it you realise you showed the properties full address in that video, despite going out of your way to cover up the serial number in the monitoring app...
We do our best, sometimes bits can slip through
Would this system be capable of charging an EV or would storage need to be added
This system only generates at a low rate so would struggle to fully charge an EV. It is really only there to cover the base load of the home.
@@OvalRenewables Thanks, unfortunately I only have room for the system covered in the video
I have 6 😁
Great!
What is the model number for the optimiser?
I believe it is an M2640
Hi, one question: Without any air circulation underneath the modules, will they not get really hot, reducing the efficiency on hot summer days?
There will be a slight effect with it being in roof however it shouldn't be a major issue.
Key question from me, what did it cost please?
I believe it was around £4K
is the solar generation meter required per regs ?
Yes under MCS rules. We are unable to generate an MCS certificate without it.
@@OvalRenewables hmmm .....makes me think they will start taxing the sun
Was interested to see a video from a a channel I'd not seen before, but immediately turned off after the drone footage at the beginning, showed an installer chancing it by shoving a length of metal trim, upwards directly on a panel. Shoddy work practice that.
Thanks for the comment. I fear you may be slightly over reacting to that. Hopefully one of our other videos will interest you 👍
Can you provide a rough cost for this specific install? I imagine it might be "cheaper" as you had such nice access to the roof, and roofspace, due to it being built at the time.
But would be nice to know how much a basic solar system would cost to install.
Use £10k as a basic figure with battery storage without battery’s around £6k
For a basic install from us you would be looking around 6-8k which includes SolarEdge and then about another 8-10k for battery storage.
@@OvalRenewables fantastic vid as always. Would this price be for. 5kW system or a small one like here? Cheers
Just a heads up, you can see the Reg Plate on that car if you stop the video in the right place.
Thanks for pointing it out
Laminate or make those One Line Diagrams and procedures into stickers . They are not going to last over time. If the owner sells the house it’s gonna be a pain for the next owner. Build things to be able to used 30 years from now without any intervention.
They are laminated 👍
Ive been trying to get a small system just to reduce costs even something. Instaler told me dont waste your time.
Its disapointing for small users they want you to take larger systems.
Sorry to hear that. Maybe try a different installer.
Same, installers dont want to take on small systems.
Struggling to get anyone here in Swindon to take on a 1.5kw install to cover baseloads.
Bugs me to give anything back to the grid
I wanted these fitted to my house but viridian said they were not taking on domestic costumers
Thanks for the message. You may be best speaking to a solar installer first.
@@OvalRenewables I actually phoned one off your list to be greeted with what! And he then complain you have not got hia permission to put his name on the list
How much would a system like this cost?
That's a key data point which is missing from this presentation. Rather pointless video seeing as it omits any information on the return on investment.
@@cyclemoto8744 I've been looking at something similar size-wise with added storage for my own home.
Thanks for watching, not all of our videos cover the cost as it can be a personal thing for the customer. I appreciate that it may be an important point to you however the cost of a similar size system may be vastly different for someone else as the installation factors may be completely different.
I personally don't think it makes the video pointless haha
@@OvalRenewables Can you give me a ballpark to the nearest £1k?
They are going to overheat with no ventilation behind them, reducing their efficiency!
The cement board on a brick wall is a bit of a waste of cement board, even if it looks nicer. Cement manufacture is terrible for the environment.
The time saving for fitting the equipment and clipping cables covers the cost of the board
I disagree as it makes fixing equipment nice and easy.
So the system needs an Internet connection, otherwise it's all guess work. Why can't the system have a visual display on site. Without the input of a third party the system could be rendered next to useless.
They removed the screen on the inverter a little while ago now. You don’t absolutely need an internet connection but it does mean the system can be monitored and updated.
bypass your meter its cheaper 😅
Haha this is the best legal way 😂
@@OvalRenewables I'm just on with getting everything together for my install not sure of the legality of installing it myself but gonna do as much as I can to keep the cost down.
@@axgtsimi Up to a 3.6Kw system you can install yourself except for attaching to the grid which requires an electrician. Once complete email a G98 (i think) form to your local electricity board eg. Norweb and you're done.
Use concrete and make better houses 🙏🏼
Sorry, but it doesn't look neater on the scruffy looking fire resistant board at all. Installing it all on that dirty looking board would irritate me if I were a customer.
Personal preference I suppose. Looks better than the wall in my opinion
Straight into adverts just so you know . RUclips sucks
Sorry to hear that
That tune is appalling and had me stop the video.
