Rain X on Solar panel
Was wondering if putting an application of Rain X or similar water repellent on the solar panel would help in keeping the panel cleaner. Any thoughts on this idea appreciated. Thank you.

The only problem I see if the solar panel is laid flat level on the roof, any type of waxy oily protectant will cause water drops to group together. When the sun comes out, those water drops can become magnifying before they dry up. I don't know if that would cause any damage to the underlying solar grid, just a thought.
