How often should you clean solar panels?

Just like cars, solar panels need maintenance too to do their job more efficiently. The most common solar blockers are dust, leaves and water. Over the years, dust, leaves, and water can cause regular problems beyond the build up of grime. At Advanced Window Cleaning, we make solar panel cleaning affordable.
