Electricity in and out

Time to do the calculations again after almost 2 years of operation of the solar PV.

We’ve written to our suppliers to ask why last year’s output (1.5Mw from the top 16 panels) is 20% down on what they projected/promised.

What’s also puzzling, as you can see from this reading, is that even at noon on a day of full sun in August, the best panel is only producing 148w, rather than the specified output of 180.
