Ok so in the Northeast it becoming more and more common to find solar panels on one side of a roof. As I was driving by a future potential clients house yesterday thinking how I would clean the front half it dawned on me if I shot it all from the gutter it gonna go over and hit the panels. Cape Cod with very steep pitch.
I am new to roof cleaning and was wondering if the chems are going to harm the panels or wiring??
I know tsp can etch glass so I guess I can't use that. Any thoughts
there is no need to use tsp anyway. It is really bad for the enviroment and does not improve the results. What i have done is spray from the gutter and then go to the back and rinse the panels down with water. Its pretty easy.
