Solar panel production figures

Have a look here and plug in your details. It'll be more accurate than your installer prediction:

JRC Photovoltaic Geographical Information System (PVGIS) - European Commission

not bad. my installer was being reasonably truthful about the estimated production
was quoted 3780kwh, and JRC estimating 3630kwh

march estimated 307kwh - actual 290kwh
april estimated 414kwh - actual 209 so far

 

[d_p]

What have they predicted for the month? About 415kWh?

PVGIS predicts about 350kWh in April for your location with 3.3kW of panels pointing true south with a 35 degree roof angle.

They have said its 390 kWh for April. It says on the paperwork that the calculation is based on the standard MSC procedure but there is no evidence to back that up. My first full year was 2% above their estimate, so either it was a fluke or they have estimated it perfectly. But yeah your link says 350 kWh which is interesting. Still not going to get to that target either!

Just thought I'd compare the different estimates I have..

Actually the estimate on this link is more than my installer estimate. 3100 kWh per year vs 3171 kWh. Its just spread out differently over the months

Daily record has been broken……just waiting for a final figure pvouput is lagging behind what my growatt is saying.

So the not so welsh weather has given me a new record on the 12th and then broke it again a few days later.

Strange day of sun, rain and sleet in Shropshire. Managed 41.3 and exported 35.5. Solid day

 

[tamzzy]

20.1 today, would've probably broke a record but for the 1h of rain/hail that we had mid-afternoon

 

[Pyr0m@nI@]{]

Record for my system today too.

[PUGSS]

Record day down hear in Devon for me with 31.50 Kwh and looking at the bell for the day a good full clear day should see a lot more

Record day for me 58.6 kWh (only had the main system in a month).

Exported 36.80kWh (peaking at 8.6kW!).

Roll on the summer

We had Welsh weather in the east today. The sun didn't show itself until half 3. The NW panels did the heavy lifting with 14.9 alone.
