Another mixed day yesterday with 3.97 O's
Should make Estimate but his will be my worst August out of five years. Still 27 O's behind my lowest total.3.795 kWp Solar PV System. Capital of the Wolds0 -

That’s reassuring, so it isn’t just me then. Yesterday I was getting a real complex with blue skies in every direction while sitting under my own personal black cloud for over 30 mins in the afternoon. I was even thinking of moving north of the Humber.
I am at 80% of my PVGIS estimate with 81% of the month gone although I estimate I have lost about a day's production due to outages. That is 69 Os so far. I don’t expect to be a star performer with my E/W system.
The PVGIS annual estimate equates to 734 Os for me. How does that compare with others, particularly those with split systems?
It is looking as though it will be a low power day today. Will we even make an Oscar?
As a general rule should we expect to exceed PVGIS over the year as a whole?Northern Lincolnshire. 7.8 kWp system, (4.2 kw west facing panels , 3.6 kw east facing), Solis inverters, Solar IBoost water heater, Mitsubishi SRK35ZS-S and SRK20ZS-S Wall Mounted Inverter Heat Pumps, ex Nissan Leaf owner)0 -
Mine (not split) is 941 Os. I usually come close but rarely exceed it. I think many others do rather better.The PVGIS annual estimate equates to 734 Os for me. How does that compare with others, particularly those with split systems?2kWp Solar PV - 10*200W Kioto, SMA Sunny Boy 2000HF, SSE facing, some shading in winter, 37° pitch, installed Jun-2011, inverter replaced Sep-2017 AND Feb-2022.0 -

Over 6 years I've averaged 793.5kWhs/kWp, but my system has a size bias to the ESE, and ESE is slightly better than E or W.
Couldn't stop there, so went back and did the calcs per system, and got:
718.5kWh/kWp for the WNW and
835.4kWh/kWp for the ESE
possibly the WNW should be 733 O's to account for one PO being down for most of a year before I noticed (shame on me).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.
