An extra day in the month, especially one like today, makes a difference for anyone using solar panels to produce electricity. February 29 was the “best” day on the month for our installation: almost 9% of the total energy production for the whole month was generated on that single day.
Looking up the numbers for 2012 seems to confirm that special relation between leap years and higher than average electricity production. Indeed, in 2012 we had the highest production numbers for all months of February in the existence of our installation. But that was not not because of the extra day, but simply because the whole month was relatively sunny from day one on – the 29th then was in fact one of worst days of the month!
Anyway, even without that 29th day we would have surpassed the average production for this February, so all in all the year has started off well enough, at least for our panels.
