–Dust, debris, bird droppings, and other grime that obstructs a solar panel’s ability to absorb UV rays can reduce the efficiency of solar panels. You have made an expensive investment in your solar system and it only makes sense to make sure the panels continue to function at the highest rate of efficiency.
Rain is not enough to wash away accumulated grime
Using a hose to rinse away dust and grime doesn’t do the job
Not cleaning solar panels at all may void the warranty
Not using the correct equipment and cleaning solutions may damage the panels
Damaging the panels may void the warranty
