..............Going down.......0.5 followed by 0.12 O's today.. Er....without snow!Coastalwatch said:A good start with 1.18 O's today but looking at the forecast ahead it'll be the 10th before any further sunshine materialises!

Ah! That’s better. So PVGIS reckons 8000kwh, my solar quote was 7100kwh which took partial shading into account.Martyn1981 said:Yep, a biggie. PVGIS uses south as the azimuth (point of interest), so -150d would be NNE. SSW would be around +30.
Don't worry it confused all of us going back.Yesterday was 0.66 Os. Another sunny day. The yield is dropping quickly. There’s 34 minutes of daily sunshine time left to lose until the 21st.8.9kw solar. 12 panels ESE, 16 panels SSW. JA solar 320watt smart panels. Solar Edge 8KW HD wave inverter.

Don't get too excited, and I'm making no promises, but both my systems have shading, but I decided to go with the full PVGIS estimate for my comparisons, so annual totals would reflect shading losses. However, my systems with Solaredge have preformed well over a decade with annual totals ranging from 97% to 110% (average 103.5%).frozen_wastes said:

So if the shading is mild, and/or only impacts one or two panels at a time, then you may average close to the full PVGIS figure.Mart. Cardiff. 8.72 kWp PV systems (2.12 SSW 4.6 ESE & 2.0 WNW). 20kWh battery storage. Two A2A units for cleaner heating. Two BEV's for cleaner driving.

Nil poi. 😖
Another duck here thanks to more snow last night and heavy cloud all day.
At least it's turned to rain now and washed the snow off the panels.

Great the panels are now all nice and clean ready for some sunshine tomorrow.Unusually we had a sprinkling of snow here this morning as well, not enough to settle, and the odd bright spot through the gloom. A lovely pink sunset took us 0.35 O!Oh, no ducks either.
