Dirt, dust, and pollen rob your solar system of up to 30% efficiency. Gain Solar Cleaning restores your output fast — at the best price in San Antonio.
San Antonio's heat, dust, and pollen are brutal on solar panels. Most homeowners don't realize how much they're losing until they see the difference.
A thin layer of dust, pollen, or bird droppings is enough to significantly reduce your panels' output — and your savings.
Between the cedar pollen, summer dust storms, and bird activity, SA panels get dirty faster than almost anywhere else in Texas.
Homeowners who track their system often see a noticeable production spike the day after a professional cleaning. The numbers don't lie.
Our pricing starts at $25/panel — one cleaning can recover weeks of lost production. It's one of the highest-ROI maintenance decisions you can make.
We charge whichever is cheaper for you — $25 per panel or $350 for a full standard set of 15. Straightforward, honest pricing every time.
Perfect for small systems or partial cleanings. You only pay for what we clean.
Ideal for systems under 14 panels
