I know that PV panels are not 100% efficient at converting light

square metre was the average figure used for that solar farm.

And so surely I've done something wrong.

Thanks again.


I have a 4Kw setup. I do an average of 4000Kwh/year.


So 456W average.... How many square metres doe you panels cover?
