Great video well done guys💪💪

Is it too heavy to do windows?

This brush is very effective....... Depending on the amount of soiling .. you need to pace yourself when confronted with heavildy soiled panels especially with those that have algie and moss around the sides.......... In many cases there will be a lot of algie and moss around the edges.... If the person goving the contract wants these cleaned perfectly make sure you offer hem 2 different prices quotes for he solar panel cleaning..... 1 for a basic going over which removes the surface soiling and the second one to remove the moss and algie But beware it takes a lot more time if they want it it perfect so make sure you price it right . Me personally i Aim to sell the the basic clean because if there is a large build up of moss around the edges it is because the customer does not want them cleaned on a regualr basis ( once yearly ) . Better to a apply a slow even pace under control through the whole contract...
