@derek-m I didn’t get the chance yet and don’t have great access. I did though spray the panels with the hose to cool them down and short a short spike so I do suspect they were just losing a bit from being too hot.

@editor splendid.

196 for me for the past 7 days. Today is a bit slow though. Been cloudy.

Solar power is seriously awesome, isn't it? I mean, the idea of turning sunlight into electricity still blows my mind. About the performance, I've heard a lot of good stuff from different solar companies. It seems like they’ve really stepped up their game recently.

@matenateson it's good. Welcome on board! We have a modest 3.6kW 9 panel array on a house which one company dismissed as 'not suitable for solar PV' based on a 10 second Google aerial picture look at our roof. We get 24kWh on a sunny day this time of year. Even on an overcast hazy day like today, oh and most of last week, we get 6-10kWh. It provides for all our daily needs, including daily ASHP hot water generation. It tops up our 13kW battery storage, and provides a little export at 15p/kWh - more than enough export to pay the £200 yearly standing charge. The solar batteries come into their own in the winter heating season when they are schedule charged twice a day at low rate periods on Octopus Agile tariff. Stored energy provides 85% of our needs at low rate to run our ASHP heating low'n'slow all day long. We save big money doing that, £500+ over the heating season, with free energy over the summer season. Renewable heating and energy just works for us 🙂

@matenateson Our PV installation took place in July/August 2022; the system had been planned and budgeted for in late 2021 and ordered in early 2022. We chose our panels from the Sunpower range and ensured our installers were on their approved list of installers. About May/June time, we were informed that the Sunpower PV panels were no longer available and the replacements would not be imported until 2023 so we were offered REC panels. I then enquired about availability of these panels (slightly lower output and not-so-good spec or guarantee) I was reassured ‘No problem, we have loads of them in our warehouse’, I accepted the substitute. Within weeks, the REC panels were ‘out of stock Sir’ and I was offered Canadian Solar; byn this time, our 21 panel installation had lost more than .5 kWp and a shorter guarantee! When it came to the installation, there were numerous further hold ups due to the mounting hardware not being ‘in stock’ too.

Throughout all this messing about, I was told that this was all due to shortages, import restrictions, Covid … blah de blah. I had also ordered a Tesla Powerwall to be installed at the same time but of course, they were in short supply too and eventually one was fitted in November 2022. I was offered a second Powerwall if I paid 25% deposit then and would have to wait until at least February 2024!

I really hope that the suppliers and installers have managed to organise their feathered aquatic friends into a straight line by now as I felt the situation was quite shambolic for me!

I did not take the installers up on the invitation to pay them about £2,500 and wait over a year for the second Powerwall; in fact, one was installed about April 2023 by the installers of our ASHP .. and at about 70% of the price! I think supplies may be easier now for most equipment - well at least I hope so. 

Regards, Toodles.

In terms of getting the most out of your panels, it's all about location, angle, and keeping them clean. Regular maintenance is key. Also, tech is constantly improving, so newer panels are getting more efficient.

If you’re thinking about getting solar, I'd say go for it. It's good for the planet and your wallet in the long run. Just make sure you do your homework and pick a reputable company.

@matenateson OK, it is a rather late response to this topic but I thought that this might be relevant to some degree.

I have 8.1 kWp of solar PV at less than optimal orientation and do suffer from some shading due to a chimney and also from neighbour’s trees in autumn before the leaves drop. I have 21 panels spread around as four arrays including 10 garden mounted. All panels have Enphase IQ7 microinverters.

I tend to export my solar production as I use a TOU tariff and can buy in cheaper than the export rate. My system was installed in Aug. 2022 and in those 25 months, the dedicated meter informs me I have produced 16,347 kWh’s. At 15 pence per kWh, this amounts to some £2,452, in my opinion, well worth doing.

Of course I need to deduct the cost of the nightcaps that all 21 panels seemed to be wearing at present… hardly enough production to butter a few parsnips! We seem to have a love affair with some very thick nasty grey clouds that are reluctant to move on…🤨 Regrets, Toodles.

Further to my previous posting, here are December’s and just part of Jan. 25’s solar production - I’m hoping this is a hint of things to come! Regards, Toodles.

I normally see a steady increase in the sunny day peaks as January progresses. There's a link to my data below but I would note that my winter solar generation is hampered by trees so there's a relatively short period when there's unimpeded sunshine (when the sun condescends to shine). December 2024 had by far the worst generation in my 8 years of data.

https://monitoringpublic.solaredge.com/solaredge-web/p/site/public?name=Liden#/dashboard

108 kW/h solar produced for the whole of December. 

10 days of January so far and up to 62 kW/h.

The negative in January is it's been almost constant minus outside temperatures so heat pump usage gone up substantially, mainly due to hourly defrost restarts.

Here's mine from 6kWp split across 2 roofs.

I have shadow from a chimney in the morning but not noticeable from the plot below (microinverters) and also have trouble with trees in the afternoon at this time of year.

@ianmk13 It wouldn’t be fair to start another thread on the theme of actual solar production as such so, with apologies, I’ll append my mini-rant / bemoanful writing to this existing one if I may.

I have observed that solar production has been appreciably lower in October ‘24 to end of January ‘25 than the corresponding months in ‘23 to ‘24. I have also been shaking my fist at the thick grey clouds that seem to have taken up almost permanent residence in my neck of the woods in SE England. I’m beginning to wonder if there is possibly a connection with the ‘global warming’ effects we are seeing in other aspects of our weather. I would be interested to hear from others as to whether their weather has been disappointing in terms of solar production over this time please. Regrets Toodles.
