It's at least 37C in the shade, so the perfect time to clean the PV with a watering can and pole. I clambered up there as it's a shallow pitch.
I'd held off cleaning them as a bit of dust will reduce generation and thus lessen the amount of power I burn off (not allowed to give my surplus away) However, when running the air con, power is king!
1630 CET The southern array output rose by nearly 10%. The eastern array 8%, but it's starting to lose the sun.
If you do clean your panels whilst on the roof be aware that if you wet the tiles they may become slippery, particularly on the east/north faces.
