Heavier buildup, however, can be more problematic. Bird droppings, stubborn grime, and debris that remains on panel surfaces may reduce the amount of light reaching the cells, which can contribute to lower energy output. For Cape Cod homeowners, seasonal pollen, windblown debris, and airborne salt in coastal areas can all contribute to accumulation on exterior surfaces.

You cannot use just any cleaning method on sensitive solar panels. Using high pressure or harsh chemicals can damage the surface coating, seals, and wiring.

Over time, dust, pollen, bird droppings, and coastal grime build up, creating a shield that blocks light from reaching the cells underneath. This build up hurts your wallet and your system's performance.
