Hard Water Stain Removal for Solar Panels in Santa Clara
Remove sprinkler overspray and hard-water scale from panel glass without scratching, recovering efficiency.
Get Rid of Baked-On Water Spots
Sprinkler overspray and Santa Clara Valley’s hard water leave a chalky mineral film on panel glass that regular rinsing will not remove. Over time it bakes on in the sun, blocks light, and drags down output — and it only gets harder to remove the longer it sits.
We use professional mineral-dissolving treatments and soft pads to lift hard-water scale without scratching the glass or damaging the anti-reflective coating, then finish with a pure deionized-water rinse so nothing is left behind.

Frequently Asked Questions
Why do my panels have white spots?
Those are mineral deposits from hard water — usually sprinkler overspray. They bake on in the sun and block light. Regular cleaning will not remove them, but our stain-removal treatment will.
Can hard water permanently damage panels?
Left long enough, mineral etching can become permanent. The sooner it is removed, the more likely we can fully restore the glass.
How do I prevent it coming back?
Aim sprinklers away from the array and schedule periodic cleaning. We can advise on both during the visit.
