Keeping Solar Modules Clean Is Easy
It's a good idea to keep solar modules clean of major obstructions like bird droppings and heavy pollen loads. They will still perform well when dirty but if these obstructions accumulate over time, a decline in performance will result. Solar modules should never be washed with harsh chemicals or a pressure washer. Liquid dish soap in a bucket of warm water with a squeegee is all you need. You can do this yourself or have a window washer take care of them. Here's Tim and Stu cleaning windows and ready to tackle solar modules as well.
