The skies varied from partly sunny to dark gray overcast from dawn until dusk. I installed two soft water line hose bibs on the roof. I placed two 50-foot garden hoses with nozzles to remain on the roof for washing the panels. Today I rinsed them with soft water, no soap, and it is about 99% compared with the full dish soap and terry mop process that I used a month ago. I need to find a couple of storage boxes for the hoses to protect them from UV damage and to prevent birds from nesting in the coils.
At one point I had rinsed more than half the panels and went down the ladder to get the second hose. While I was down, and with cool wet panels on the roof, I saw all three inverters rise above 7000 watts as the sun moved fully out from behind the clouds for a minute or two. The production meter speed was impressive. I rushed to get my video camera and recorded it. Afterward I went back to the inverters and they were all back below 5000 watts again.
Note: Saturday is all off-peak so the readings indicated we pulled 7KWH from the grid during the day due to high demand for hot water and clothes dryer... or just lack of sun-light for production at some point. The starting reading shows we pulled 24KWH from the grid during the night. I suspect this was mostly the water heater that has a timer set to run early in the morning.
Last reading from yesterday, first this morning, noon, and last for today:
