Solar Panel Cleaning in Austin

Deionised-water cleaning that restores lost production without scratching glass or voiding a panel warranty. No soaps, no abrasives, no pressure washers.

Top Four Reasons Panels Get Dirty

  • Central Texas Dust and Cedar PollenBetween the dust, the cedar and the oak pollen, Hill Country arrays build a film that a light rain does not touch. Soiling costs more production here than most owners expect.
  • Sprinkler Overspray Leaves Mineral DepositsHard water hitting hot glass dries into scale that will not wash off. Irrigation aimed anywhere near an array is one of the worst things for it.
  • Birds, Bats and What They Leave BehindDroppings do not rinse off, and a spot dense enough to shade a cell can drag down a whole string through the bypass diodes.
  • Debris Collects at the Frame EdgeThe bottom rail of every panel catches a line of grit that holds moisture against the seal and shades the lowest row of cells first.

Top Four Solutions to This Problem

  • Measure Before and AfterWe record production around the clean so you can see what it actually recovered, instead of taking our word that it was worth it.
  • Deionized Water and Soft Brushes OnlyNo detergents, no pressure washers, no abrasives. The anti-reflective coating on modern glass is easy to ruin and impossible to put back.
  • Inspect the Array While We Are Up ThereA cleaning visit is the best look anyone gets at your roof. We check for damaged glass, loose clamps, chewed wire and critter activity while we work.
  • Set a Cadence That Fits Your SiteA house under oaks needs a different schedule than an open lot. We tell you what yours actually needs rather than selling everyone the same plan.
