PV Cleaning Equipment

[Ravenvalor]

Hello,

I am thinking about cleaning PV panels for my customers. Are there any commercial grade cleaning systems out there? Most of the stuff on Amazon looks cheap. Karcher has a line of brushes but am not familiar with their quality.

Thanks for the help.

How big an array are we talking about?

I would ask window washers what they use, maybe.
