Seven weeks ago, I reported our sunniest day ever, as measured by our solar PV production. Well, this Sunday was better:
The horizontal time axis runs from 3:00am to 9:00pm GMT. The vertical axis runs from zero to 8kW.
More than half a kWh better! And given the lower peak value, and the cloud-caused dips in the generation, this extra is clearly due to the longer day in June than in April.
Last June was a bit rubbish for sun.
