But it's not just the terminology that's at fault here, it's the concept of the 'O' when using the the kWp of an east-west system.
Good to see you back Kernel Sanders. You were right, it topped out yesterday at 0.55kW.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 -
Cheer up everyone !
Only a couple of days to go before we 'turn the corner' and we should all start seeing increased output almost every day.NE Derbyshire.4kWp S Facing 17.5deg slope (dormer roof).24kWh of Pylontech batteries with Lux controller BEV : Hyundai Ioniq50 -
Indeed. Roll on the spring !Cheer up everyone !

Yes, it makes me feel inadequate but the reality is my system comes in close to PVGIS (v5), the odd month excepted. What surprise me most is the difference between ENE and WSW (the real orientation of my panels) at this time of year. Not too bad when it is uniformly bad like yesterday but on a sunny day it is huge.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 -
Why thank you, Ken. It's just a fleeting appearance, with a reminder that if anybody wants to ask/tell me anything, they really need to PM if I've not posted for a couple of days.Good to see you back Kernel Sanders.
Size isn't everything, Ken!Yes, it makes me feel inadequate
Like Eric, I don't 'recognise' the 'O' (I produced 672 Wh today), but wouldn't it make a bit more sense if the denominator was the inverter capacity instead? (providing you don't have an overly big one
) 0 -

Unfortunately I do have an overly big one on the east roof; 3.6 kw when the most generation I have seen is about 2.5kw. Still scope for more panels on the same inverter. The west roof at 3.6kw for 4.2 kwp panels seems about right.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 -
I've just noticed 'Solaris inverters'. If you've ever actually generated more than 4 kW, then I'd have thought the achievement too infrequent to justify the expense of two inverters. In fact if you decide not to add further panels, then by the time the first inverter gives up the ghost, won't your arrays have degradated to the point where the other inverter will be able to cope with both? (assuming it has two strings, of course).Unfortunately I do have an overly big one on the east roof; 3.6 kw when the most generation I have seen is about 2.5kw.
