Solar Panel Cleaning in San Antonio
Dust, oak pollen, sprinkler overspray, and construction dust build up on solar panels across San Antonio faster than most homeowners expect. Texas Window Washing LLC cleans solar panels for homes and businesses throughout San Antonio and the surrounding Hill Country using purified water and professional water-fed equipment — the same detail-first standard we bring to every window we wash.
Why Panels in San Antonio Get Dirty So Fast
Live oak pollen in spring, blowing dust, water spots from sprinkler overspray, and construction dust in fast-growing neighborhoods all leave film and residue on panel glass. Dirt and film block sunlight from reaching the cells — and clear glass is the whole point of a solar panel.
Our Solar Panel Cleaning Process
We clean panels the gentle way: purified water fed through professional water-fed poles with soft brushes designed for solar glass. No pressure washers on panels and no abrasive scrubbing. Purified water dries without leaving mineral residue behind.
Every roofline and panel layout is different, so we assess your setup during the estimate and explain exactly what the job involves before anything is scheduled.
Solar Screens: Washing, Removal & Custom Fabrication
We also take care of the screens that shade your windows: solar screen washing, removal and reinstallation, and custom solar screen fabrication and installation. If your screens are dusty, sagging, or missing, just add them to your estimate.
How Often Should Solar Panels Be Cleaned?
It depends on your surroundings — dust, nearby trees, construction activity, and bird traffic all play a part. Many of our San Antonio customers schedule panel cleaning once or twice a year, often alongside an annual window cleaning. We give an honest recommendation with your estimate based on what we actually see on your roof.
