Brush Size, Solar Panels Large Commercial Glass


#1

When we are cleaning solar panels using a small brush it cleans it but hell of lot of strokes.
Also when comes to do large commercial glass.
So question regarding the above WHICH SIZE WOULD YOU LIKE/ WANT OR DO YOU USE? (BRUSH)


#2

My general go to is a 12" for everything except large commercial. In my area solar panels tend to be pretty baked on so a 12" boars hair along with a gods scrub pad comes in handy.
