Hiya Oscar. Hand on heart I hadn't noticed that. I guess I'm so used to seeing everything expressed in kWhs per kWp (O's to you and me) that it just goes over my head these days - even if we are regularly informed that it's made up or meaningless! :laugh:
Mart.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.
For general PV advice please see the PV FAQ thread on the Green & Ethical Board.0 -
Afraid there have been days when I've generated nothing at all - in which case it doesn't matter if you call it 0 kWh or any other silly unit you care to substitute !
Come on Eric, why is an intelligent man like yourself calling kWp a silly unit ? :rotfl::rotfl::rotfl: 2.5 kWp PV system, SSW facing, 45 Deg Roof. ABB Inverter, Monitor: 'Wattson'.

Even on a day when you generate nothing at all, your system kWp remains fixed (and is not something you might substitute for kWh).NE Derbyshire.4kWp S Facing 17.5deg slope (dormer roof).24kWh of Pylontech batteries with Lux controller BEV : Hyundai Ioniq50 -

On 3/4/14 I had 2 O`s......should I expect even less than this some days, maybe in the depths of winter?
What`s the lowest anyone`s seen?
Or in cold hard cash terms....£0.00p

I've made more today already than I did in the whole of yesterday!3.924kWp (12X327Wp SunPower). SolarEdge SE3500 inverter.

Well, this will probably be the last ever time it happens, but today was my best ever day with my panels, whilst yesterday was my worst. Though I've only had them three weeks. I anticipate having many good days over summer and bad days over winter so I doubt anything like that will happen again.
Goes no way to making up the PVGIS shortfall for April so far though.
So that's over 20kWh today, and a HAWAII! Despite a fair amount of cloud.3.924kWp (12X327Wp SunPower). SolarEdge SE3500 inverter.

Phew-eee. Weather spokespeople got it right for a change.
WNW 7.2kWh
ESE 8.6kWh
SSW 8.75kWh
Combined 24.55kWh(3.77 O's)
And the wife still didn't manage to do all the washing
