I reckon I get about a 10% increase in output when I clean. My panels are only 2 degrees off flat, so the base, where the water pools, get's very dirty. And there's always a few panels with big bird droppings.
I guess in theory if I cleaned them every day, I could get infinite output ....
Thanks Tom. Having just watched 2 magpies this morning drop huge amounts on 2 panels,and then getting up and cleaning them (the panels, not the magpies, ..lol ) reminded me of the need to have some form of deterrent.
Bird repellers - Some are turned on all the time, and some are only turned on by a motion sensor. Battery powered and solar powered. It seems the pulse is either sonic or ultrasonic.
Has anyone used bird repellers ?
