Welcome to the latest video in a series about our solar panel and battery installation in the south east of the UK.
With the amount of cloud and rain that we've had in the south-east of the UK in November 2022, how has that impacted our solar generation?
And what is the impact of our Batteries having to be turned off due to our comms issue?

Just got my solar system installed - not completed till next week but Solis cloud is up and batteries are charging. Looking forward to your video on how you track all this data.

Here in Norfolk UK, November '22, usually get c. 3,600 kWh per year from a 4kW array. Panels are 10deg South of East (so at about 100deg). On best day exported 5.1 kWh. Exported 50.34 kWh for the month.

Thanks for posting your videos which I've watched with interest. Like you, we had our solar system installed in September 2022 & also like you, we have a slightly off kilter, East-West facing roof. We have 8 x 395W JA Solar panels on our West facing roof (the East side being somewhat compromised). TBH, I have been very disappointed by the performance of the system so far. I have come to realise that if you are, in the base case, a low power consuming house (we were using 2,137 kWh/year) solar is simply uneconomical. Far from being the 'no brainer' it's touted as, it will take 15+ years for us to recoup the £8.7k the system cost. I have taken your solar generation numbers & compared them to mine. Adjusting for array size (our 3.16kWp to your 6.16kWp), our array is only giving about 83% of what you see. Why? I have no idea as the roof is not shaded in any way. Our December solar generation has averaged a pathetic 1kWh/day. IMHO, spending so much dosh to save 34p/day is self-evidently ridiculous!

Thank's for your comments - glad the channel is useful! In terms of our setup - we do have panels on both East and West - the way I read your comment is that you have the west facing only? That may be part of the difference? In terms of performance - our peak generation in December has been 5.60kWh on 2 separate dates - we are averaging about 2.75kWh a day. This is significantly lower than September and October, but the solar day is short and where the sun rises and sets is not optimum at this time of year. The sun is barely above 12 degrees above the horizon at noon, so the strength of the solar, and the angle it is hitting the panels is compromised. As such my savings are also minimal this month (about £0.80 a day), but come the late spring and summer I should get days when I need no grid import (subject to the battery issue being resolved). That's when I'm expecting the payback to start really taking effect.

@@East2WestSolar Yes. My panels are exclusively on the West facing roof. I did contemplate putting panels on both sides of the roof but when a single side of scaffolding is a £700 on-cost, it's hard to justify relative to what you might save. There are lots of things you only realise once you've lived with a solar system for a while. The thing I wish I'd understood beforehand is the misalignment of supply & demand. My leccy demand is high in winter (40% of my annual use is in the four winter months) when solar is low to non-existent & low in the 8 months when solar is in abundance.

@MrButuz Год назад

Well if your gonna do east/west you really need to do both as your system is not gonna do any generation in the morning at all (maybe a couple of hundred watts ambient) so you're basically wasting half the day? Not an ideal system Also 8.7k seems really expensive given that 8 x panels and an inverter runs to about £2500?

@MrSensible2 Год назад

@@MrButuz My 3.3kWh battery adds £2.5k, the 4 X Tigo optimisers another £500 & where I live, £700 for a side of scaffolding is cheap. I probably jumped on the solar bandwagon at the wrong time, in August 2022, when predicted power (& gas) costs were going through the roof & Boris & our f*****g useless government had abdicated any responsibility for the imminent shitshow. The whole world & his dog wanted solar asap. My big problem was finding anyone a) to give me a quote & b) to do the job before February 2023! So yes, I probably overpaid but sometimes you have to make a decision, at speed, on incomplete data C'est la vie!

@MrButuz Год назад

Yes it's been a bad one - so much rain and cloud and very little winter sun. My mini 2kw array that I was very pleased with in the summer - has underperformed spectacularly this winter and has struggled to cover the base loads of the house - zero meaningful power put into the battery since november the 2nd :(

@jebeda Год назад

"Daylight savings time" is in the summer. The UK is currently on "standard", non-shifted, time. GMT.

@East2WestSolar Год назад

Yes - good point - I knew what I meant to say and got it the wrong way round!

@steveperkins3215 Год назад

Just looking out of our window I guessed November to be a poor generating month. Early December here in the North West seems to be very much brighter. Interested to see your December stats and very interested in your Excel template, we use 'Numbers' and wonder if it will be compatible or convertible. Just month to go to our install and at 35.6p KWH I am not expecting our Heat Pump installation to be that economical at least in the early months of the year. Time will tell! Thanks again for your update.

@East2WestSolar Год назад

Thanks Steve. I'm not familiar with Numbers as software - but from experience the other spreadsheet solutions offer compatibility with Excel. Good luck with the install!

@sacks7544 Год назад

This is great to compare daily generation with my DIY 6x380w south facing installation. For the month i averaged about 39% of your generation. I only installed mine at the start of sept this year after the heatwave so i have little data available to me. I dont have batteries and as this was DIY anything surplus trickles back into the grid unpaid. I am considering more, i have huge roof space like yours, east/west to consider or I could build "man cave" at the end of my garden (i have no close neighbours). This would likely be a battery system. Can i ask, why were your east facing panels placed low down on the roof, surely they could have gone higher to get more sun

@johannappel9582 Год назад

Hi Keith. Thanks for the video, which was very useful. I've had my solar and battery system installed in November. I also have a Solis inverter. We use a lot of electricity as we don't have gas and all our heating runs of electricity. I charge my battery overnight on the Octopus Go tariff and use it during the day alongside any generated solar. I've noticed that the inverter exports small amount of power to the grid, even when the battery isn't fully charged - do you have the same issue? I wonder if that is normal.

@East2WestSolar Год назад

Thanks' Johann. With regards to the Inverter sending power to the grid when not charged - I believe it's to do with how much can go to the batteries at a given rate. If you have more energy than the battery can support in terms of charge rate - the excess will go to the grid.

@EXSKIN Год назад

Made 50Kwh in November only had it installed since Oct 28th(only logging from 09/11 as Solis sent the wrong part on install and 1 day the system was off line had to reset data logger ) east/west 410w 10 panel 5kw Battery. 3/12 is the best day so far, made a whopping 3Kwh North East England.

@russellstewart5194 Год назад

Hi Keith. Thanks for the video. The information you provide is very interesting and useful. I hope you get the battery issue solved soon. I am assume this is being done free of charge? I note you mention the Agile tariff. I too would like to move to this once I get solar but I had a look at the daily costs and it look like the cheapest was higher than the 34p on a variable tariff. I am not sure if I am 100% correct but if so it’s probably worth asking them for recent figures. Also do you know if going on the agile tariff locks you in for 1 year or can you leave at any time? Great video keep them up. Thanks

@racingrob108 Год назад

I have also considered this but have noticed that the cheapest rate is very rarely lower than 34p. I am looking at going into an economy 7 tariff

@East2WestSolar Год назад

Thanks Russell. The Battery issue is all under warranty - so worst case scenario if they need replacing then my warranty will cover that (and I've got email confirmation of that from the installer). With Octopus I believe you can move tariffs at any time. But I can see from their page around the agile pricing algorithm that they have introduced a minimum around when the government cap can be applied - so I think you might be right that it's not a lot cheaper than now (I pay £0.38 per unit, and looks like to your point it will only reduce to £0.34).

@jamesnolan3697 Год назад

Hi keith.ive thanks for the video.what direction does your east roof face .I've got a 4 kw system facing sw and I'm thinking ofth getting a 5.5 kw system instald on the NE and 19 KW give energy battery .the roof is facing NE abouts 55 degrees.do you think it's worth doing thanks jim

@East2WestSolar Год назад

No Problem James. Our East facing roof is facing about 85 degrees off of north, so about 5 degrees north of due east. I can't give you a recommendation as I'm not a certified installer; however there is a very good website provided by the EU that allows you to calculate the potential output. As RU-vid won't allow links - do google "PHOTOVOLTAIC GEOGRAPHICAL INFORMATION SYSTEM". This site allows you to input your roof pitch angle, the orientation of the roof and the proposed panels that you wish to install. I'd also consider the surrounding environment. Although we have our neighbours house relatively close, I knew by our orientation that at the height of summer, the east roof would be in sunlight very early in the day; and that is borne out by our september data.
