My system did an average of 3.51 O's but it becomes more realistic than a comparison of 246.3 kWh to 400 kWh....
Think you are very correct, for a simple soul.....:D 2.5 kWp PV system, SSW facing, 45 Deg Roof. ABB Inverter, Monitor: 'Wattson'.

5 Ps and 3 Qs for me yesterday, but then I never did mind them.

No, this sentence specifically excludes them :-but you'd need to be absolutely certain that it was a valid comparison - if the other set of panels were pointing in different directions or subject to a different degree of local shading the comparison would be no help at allNE Derbyshire.4kWp S Facing 17.5deg slope (dormer roof).24kWh of Pylontech batteries with Lux controller BEV : Hyundai Ioniq50 -
1kWh so far today. I'm more used to having 13 by this time. This is bound to be my worst day ever.3.924kWp (12X327Wp SunPower). SolarEdge SE3500 inverter.

Me too.
Heavy showers followed by torrential rain...no sun (or O's) whatsoever.
Today = 2.6kWh:(
At least my panels are clean:rotfl:16 Sanyo Hit 250s.4kWp SMA 3.8kWp inverter. SW roof. 28° pitch. Minimal shade. Nov 2011 install. Hybrid car. Ripple Kirk Hill. N.E Lincs Coast.0 -
2.7 kWh here. Perhaps a tad disappointing but it's still earning more than the cost of keeping system in place. And I'm quietly confident that we'll have a lot of better days between now & November.
Very little rain here today - but just enough to ensure that tanks are all 100% fullNE Derbyshire.4kWp S Facing 17.5deg slope (dormer roof).24kWh of Pylontech batteries with Lux controller BEV : Hyundai Ioniq50 -
2.7kWh here today as well.
Forecast is for much the same over the next few days:mad:
Ah well, at least the panels are getting a regular clean.4kw (16X250w Sharp). Samil Solar River 3680 TL inverter.
