Maybe it is me and I am doing something wrong but I have tried planning a route in northern France. Total distance is 354 miles in my MG5 EV (range 185-200) and it wants me to stop for charging 6 times.

I have a long bungalow where the length is faing east/west. I'm looking at 18 panels split over the east /west roof with only 3 facing south :( Octopus seem to think that it will be a good ROI so let's see...

Just before watching the video, I noticed some discolouration on some of your modules. Are you worried at all about that? Back to viewing now 🙏

DeScript is what you need to not have to worry about changing your words on the video not syncing with your lips. Failing that 11 labs.

Hi there I have had my heat pump since 2007 then the cost was £5 300 plus 5% vat I've got no complaints about it my hot water is at 60° and my radiators are 58° got a hot water tank perfect set

Great summary, and thanks for sharing your journey. You may remember I also used Dorset Solar Solutions and have been blown away by the quality and service they offer, lovely couple too. For years we thought our SE roof was non optimal but 18 panels have outperformed the forecast in all months bar November (and probably December) thanks to persistent cloud. Interestingly my neighbour had a similar 12 panel array and slightly smaller inverter which performs better than mine on dull winter days. Keep up the great work!

It’s interesting that your generation exceeded expectations even when it was generally considered a bad solar year. A good year would absolutely smash it! 🎉 Great summary as always. 👍

HORSESHIT....

I’m still out on the North for me financially, got some quotes for my garage for solar and wow 4 panels 1.76kW and a 1.5kW Solis inverter south facing shade as between two houses but detached from the house, all the AC side of the install was already done AC isolators and cable so was just a case of all the DC stuff inverter panels and frame. I got two quotes first a National company £3,700 the second a local company £4000 when I told the local company it was too much that was cut to £3500 and a ten year warranty put on the inverter, I forgot to mention it’s a flat roof and 8 foot high from the ground. Glad I tasked myself with the job in the end cost me about £1500 including me reinforcing the roof getting Doncaster Cable not the cheapest but by far the best external design and then the water weighted ballast feet for the panels that was the most expensive thing and good pair of crimps and MC4 connectors bare in mind I had to pay vat. From what I’m seeing from generation in the winter poor generation even with the bi facial starting to think bifacial is a bit of fab, I’ve placed fire clad white sheet on the roof guess will have to wait for summer. As winter generation is really poor I’ve now doubled down for summer and DNO approval to up it to 3kW inverter waiting on solar tech to catchup at the panel level which seems to be on a fast pace and as the panels are only 8foot from the ground won’t take anytime to change them out. Estimated about two to three years to get really high watt panels more or less standard size. In the end wish I opted for a 3kW inverter in the beginning but the the house inverter was only able to handle 5kW for whole house backup now I’ve got a 10kW whole house backup so don’t have that issue if the grid went down it would be able to handle the solar generation. As for batteries do your calculations on use and double it, im now looking at doubling my stack this winter sun has not been grate so the current stack runs low with washing drying cooking all off of the batteries think 34kWh will be enough for me 😂

For detailed breakdown there. Your COPs are really impressive, especially in the winter months. The Valiant doesn’t seem to be struggling through the cold ambient temps and inevitable defrost cycles. Did your rad sizes go up by much?

I have a 48v pack from a forklift. It gives me 70kwh of storage. Yes it’s slightly bulky, but it’s not sitting in my living room at the end of the day. Connected to a Sunsynk 5.5kw, keeps me off grid for 8 months of the year, and off peak for the remaining. Minimal maintenance, and no worries about cold weather like the lithium. At £28per kWh of capacity you will not find better 👌🏻

Maybe I’m misunderstanding auto-blip, but I thought it was the electronic control for rev matching when using the quick shifter and going downward through the gearbox. In that case the clutch is not engaged so wouldn’t be affected by the switch on the clutch control. Makes more sense to me that the switch disengages cruise control when you pull in the clutch, which is what happens when I pull in the clutch on my bike. So glad you got rid of that ugly wing!

Hi there I'm thinking of getting panels (just got a heat pump) but afraid that any changes in the export prices in the UK will decimate the payback period. In fact, all online calculators quote 2/3 of the ROI as coming from the export rather than domestic use. This is calculated on the 15p/kWh by Octopus. Any thoughts of this? How likely is the UK to eventually fall into the same export price trap as California?

Looking at your system may have been better to only have the north and spent the money from not doing the south panels and bought a battery, better control and quicker payback hindsight is a wonderful thing.

Give us the exact orientation. Or are they exactly NW? I guess a big difference between NNW & WNW

Like you I went with Option B. Size over orientation. I maxed out the WSW facing roof with 12 panels and the ENE roof with 7 panels due to gable issues. 5Mwh for the year, very happy with that. Payback is looking at year 7. Interested to know how you calculate your cost benefit, there are so many ways I have seen of doing it, i'm just plain confused !Gave up in the end and just used Gary Waites spreadsheet from his channel.

You mention start up is better for the NW panels. Could you explain that some more, like how much earlier do the NW panels start up? This might be worth making a separate video about. If I understand it correctly, you have 16 panels on one string (facing NW) and 6 panels on the other string (facing SE). I am not sure I understand why the start-up voltage would matter so much. The way I understand it, the voltage produced by the panels depends on how much current you draw from them and the temperature of the panels. If your panels get hot, the voltage drops and you want to have a string size that does not get below the start up voltage. E.g. if your Voc is 28 V, and the operating range is 65-450 V, start-up voltage 120 V, 6 panels will start up at 168 V and 16 panels at 448 V. The voltage will get lower at high temperatures and when the panels produce power, the MPPT will draw current and find a lower voltage point where it can get the most power out of the panels. Note that I think this also means that the NW facing panels might not be able to operate in very low temperatures as the Voc would be more than 28 V and so the string voltage would be above 450 V. To avoid such problems you might consider making two strings of 11 panels, since you have optimizers which can compensate for the difference in orientation. If there really is so much difference in start-up time for the different strings, I would love to see some examples. You should have the data for that.

You're right R290 is an environmentally better way That's all

It is interesting, back in 2018 I had to search quite a bit to get an installer who would put panels on an east west roof as they stated the payback would not be good. 6 years on and the 10 east and 10 west panels yield about 10% more than our 16 south panels. The useful aspect of the east west array is the seasonal yield which follows the seasons. Payback wise, I believe we are now evens after 6 years, but it depends on how you calculate things and the variable nature of electricity prices. Really my conclusion is with the way panels have advanced, if a location has a good surface area (aka startup voltage) then put panels on !

Enjoyed your presentation and was surprised the total cost was as low as it was. My only caveat is the way you allocated costs tonthe NW section adding £1k from the SE which was fine for your circumstance given the 2 phases of installation, however if you were to install panels on as a single installation how might your experiment have looked as thats my most likely route? As conventional wisdom only states S facing panels give the optimum return but hardly anyone has a house with the ideal orientation.

Having my East and West roof covered in January, with an 11KWH battery. Really looking forward to doing my little bit to help the planet, never have a power cut and saving more than the £200 per year that the money is earning in interest in the bank❤❤.

Maybe the sum is max number of panels with min amount spent on scaffolding?

8:30 A or B ? I'd go for option B. Fit as many panels as you can. I live in the lucky country. 30 panels 13.2kw with a 10kw inverter. In six months it has just produced 9MWh😯 (only just - I'm really pleased). Almost exported twice as much as we've used. The drawback is our feed in tariff is 8 cents kwh. Compared to our peak rate of 55c per kWh (feed in 7kwh to get 1 kwh at night - no net metering here). My cost of production is 0.6cents per kwh for 9 years. I expect the system to last longer that thou. I intend to get a battery next year which will increase my production costs but my energy resilience will get me close to independence. My next water bill will be more than my power. All the best for your journey.

Will you be posting the results for the whole month of December when they come in which I'd like to compare with mine? I had my installation - East/West - just a week ago and so far the results have been dismal (about 0.26 KWHr per Kwp per day).

Option C, do as many roofs as possible, ideally all at the same time. I will be interested to see your choice of battery, and size. I've swapped to Go, first day my electric costs including SC was 2p, I expect the second day will be similar, that was yesterday. That's extremely low for December. I've been on Flux since April 2023, last year and this year my total cost for gas and electric has been negative, I've calculated that running the entire year on Go I'll be a further £300 negative.

I should be doing something similar soon, and i had similar feedback from installers saying it is going to be a waste of time. This makes me comfortable with my decision. The only difference will be some 20 or 30kwh of batteries on top as the price seems to be fairly good.

NW not N - makes a difference. You put the panels on NW because that's what you had available. I have SW roof and that gives 6000kWh/y. Also depends on technology. Maybe new stuff better. Mine is 8 years old. On a sunny day in autumn the generation can drop from 5kW to 1kW as soon as the shadow from next door's roof touches the bottom of the strings in the afternoon. The other side of roof NE only gets a small amount or direct sun around mid June when the sun is low in the sky early and late in the day and when you don't need it. I guess SEG has changed this financial calculation as well. I was on deemed export via the original FIT for most of the time as I had no smart meter.

Our 5 floor office building is kept at 21 C easily by 2 ground source heat pumps, but a colleague who WfH has an air source pump and is always on calls with her woolly hat on.

Your videos are incredibly useful. I have a NE roof (+ large SW area). From your data the NE seems very useful on high generation months for maximising production. How is it in lower generation months - how much does it help when there is little generated on the SE?

This summer i was in my garden looking up my almost exactly N facing roof and the sun was shining full on the roof (no panels though) so i can see exactly where you're coming from. As you said seems this years weather has helped, the more diffuse the light eg cloudy then the direction is less relevant and Oct-Dec has been miserable weather wise.. I did , in effect what you did re your N vs S, to explain, I have a S facing garage roof which isn't worth installing by itself due to shading during mornings and afternoon, however the incremental cost when i3w as getting the house roof done made it a no brainer, as i effectively just paid for the panels.

The recent announcement from Ofgem regarding standing charge free tariffs may make people want to reconsider having the meter removed. Its probably better to keep the meter even if its not connected to anything if there is no standing charge.

Had my gas meter capped off and recently recieved a letter saying there are works in my road to replace the gas pipework. I've written to them to ask them not to connect up my property on the pipe replacement and they agreed. Bit niche but interesting nonetheless.

Heat pumps are a total scam like all green net zero garbage. They dont tell you that your electricity bill will go through the roof.

I'm in Australia and had my gas disconnected 2 years ago. Fully electric house with solar, and EV and it's been fantastic. Saving $4500 per year in energy (elec, gas and fuel).

Even if I save a ton of co2, when I look at the big picture humans put 34 billion tons of the stuff up there in 2023.

You can't really say in UK a heat pump uses solar power. Perhaps a few with panels and batteries could claim to. But for me, it's mostly dark in the heating season and seeing as only 0.5% power came from solar midday it's of no value. So, I reckon my ashp is either powered by gas or wind. Look at biomass, it produces more co2 per kWh than coal. Look at the subsidies Drax has raked in. They are due a load more too! Even nuclear has it's downsides. More than half the heat goes directly into the environment. Then the billions that are going to be needed to do the clear ups. Wind power, when the wind isn't blowing have to be supplied with power (grid diesel?) Then when it is windy, the consumer pays hundreds of millions to turn it off. So, electricity being 4x the price of gas is realistic, taking all the inputs and wastage into account.

We disconnected from gas just before the big price hike. Meter removed and pipe sealed by Octopus, subsequently inspected by SGN a while later. BUT: A year down the line they came back, not to check the work, but because they were required by law, after a year, to cut the domestic supply pipe at the Gas Main supply pipe. As records from the seventies were crap, (plans had a pavement where my drive is, and the Gas Main runs under said non-existent walkway), they had to dig 2 huge holes to find the Gas Main. This was done at no cost to me, and I am happy with what they had to do, but a pain non the less. Do not be surprised if they come back to do the same to you. This must have cost well over a Thousand, over multiple visits, with holes open for over a week. They did it because they were REQUIRED to. While the situation may have changed since mine was done, I somehow doubt it!

What's to (hypothetically) stop you from now connecting a safety compliant yet unmetetred valve assembly / pipes and enjoying free gas?

I would like to make people aware that these items give these companies implied rights off access, you may think "well yes ofcourse in case of an emergency, ", but when they break into your home & use this as an excuse for whatever they wish. You may feel differently.

What I don't like is the way I think I am misled over co2 emissions. I think that the figure I see on the charts is the amount of co2 at the generation plant. We have to look at "Life Cycle Assessment" to get a proper understanding. For example, my car is quoted at 150 grams a mile but if I do my actual co2 its 220 grams a mile. If that's not bad enough, the real amount of co2 per mile is found by doing a "Well to Wheel Assessment" I did the sums.in the past and I think it came out at 36% more.

Our gas meter is being removed in mid January. That'll be a bit more contribution to the overall payback! It should be easy like yours. The induction hob is ready to be fitted.

BG over projected your usage so they could over-inflate your monthly DD

Oh dear lol

Shite

Do have one figure. How much you finally electric bill , including standing charge for gas and electric. Without all the extra charts just a final bill.

Yes they save in all sorts of ways and the thing is that as the grid gets greener all the electric powered devices become greener to use. Gas is gas and will always be bad.

I had my meter removed over two years ago, I have had 3 visits to look at the gas. 3 to look at the electricity meter. It was the same chap every time Octopus obviously didn't believe I have running the whole house without paying them anything, only the money i left in from the summers Solar panel payment.

I would be looking at the max kWh daily usage and trying to get close to that with battery storage so you can charge up on cheap, green electrons and discharge when it’s expensive and dirty. If this seems like too much, make sure the batteries can force-discharge onto the grid because then you can discharge just before off peak starts and make more money exporting than you paid for the power in the first place. You’re then helping to balance the grid and making a tidy profit to boot!

Just got our Gas meter removed yesterday.

Living thee dream.😃
