Solar Panel Cleaning in the Central Valley

Central Valley dust cuts into production every summer. We rinse panels clean with the right water and the right tools so your system performs the way it was sized to.

Between the dry season, agricultural dust and months without rain, Valley solar arrays accumulate a film that measurably reduces output. It's a slow loss, which is why most homeowners never notice it — the monitoring app just quietly reports lower numbers than last year.

We clean panels with soft brushes and purified water, never abrasive pads, harsh chemicals or high pressure that could damage the anti-reflective coating or force water into seals and junction boxes. We work from the roof edge or from ladders with the array's mounting and wiring in mind.

The best cadence in this climate is once or twice a year — ideally in spring after the pollen drop and again mid-summer once the dust has built back up.

Common questions

Does cleaning solar panels actually increase output?
On a dusty Valley array, yes — soiling is a well-documented cause of production loss, and removing it restores what the dust was blocking.
Will cleaning void my solar warranty?
Manufacturers generally require gentle cleaning with soft tools and clean water, which is exactly the method we use.
How often should panels be cleaned here?
Once or twice a year for most Central Valley homes; homes near orchards, open fields or unpaved roads benefit from twice.
