I have solar panels on the roof of my trailer which is 13ft 5in tall.My wife does not want me on the roof anymore. How can I keep the panels clean because it gets dirty quite quickly?
Maybe use a stepladder (or even scaffolding) and a car wash brush with a long handle, something like this (just an example of the general kind of product)?
I have a brush somewhat like that for general washing of my RV. It sure is a lot easier than a sponge or rag in the hand and a ladder for washing the sidewalls!
