Exactly so.

Don't PV panels get quite hot in sunshine, hotter than a glass
conservatory roof I would have thought. Maybe too hot for
algae/lichen/moss to survive on for long?


They are running at 7-800volts in strong sunlight, I haven't dared

As they are on a bungalow it would not be a great problem to clean
