Does cleaning solar panels really make a difference?
Yes. Dirt, dust, and debris can reduce energy output. Cleaning helps restore efficiency and ensures you are getting the expected performance from your system.

How long does solar panel cleaning take?
Most residential systems can be cleaned within 1 to 3 hours, depending on size, access, and level of buildup.

In most cases, no action is required from the homeowner. We follow safe procedures when working around your system.
What are signs my solar panels need cleaning?
