[quote=moneymaker]svelte you are comparing output on different days. I am talking about a more scientific way to measure output.If my neighbors output was 19.1 on Wednesday and 27.4 on Thursday and my output was 26.95 on Wednesday then assuming the same clouds and weather for 2 people in the same neighborhood then my output should be 38.66, but if after cleaning them in the morning I get 41.4 then I got 7.1% more electricity than if I had not cleaned them that morning. The way you are talking you are comparing day x1 with day x2 which involves too many variables. The number of panels or type or age do not even come into play with my way. By the way if I were to maintain that output over the summer it would save me $100.[/quote]
Wait, what?
You compare different roofs and think that is more scientific?
I don’t know what to say. Except maybe you own or plan to own a panel cleaning company.
