As you can see on the graph above, it was a cloudy day all day yesterday. The sun’s photons did reach the panels all day, mostly between 11 am and 1 pm. The solar panels still generated over 9 kWh of power yesterday. If you compare graphs from early September with yesterday, the time the panels start picking up photons is later, after 6 am and stop at 5 pm, not 6 or 7 like before. The Fall is here! I wonder what the kWh would be on a larger system yesterday, more panels more power of course. I will ask Robert what his smaller system, 2.9 kw made yesterday or maybe he can leave a comment here.
