Why Solar Panel Cleaning Matters

25%

Lost Efficiency

Dirty panels can lose up to 25% of their energy output. That’s like paying for solar and not using a quarter of it.

$$$

Money Left on the Roof

A typical Bay Area system loses $200–$600 per year in production from dirty panels. Cleaning pays for itself.

10+

Years of Protection

Regular cleaning prevents permanent etching from bird droppings and mineral deposits, extending panel life.

Why You Shouldn’t DIY Solar Panel Cleaning

We get it — it seems simple. But there are real risks homeowners don’t think about:

Tap water leaves mineral deposits that bake onto panels in the sun, permanently reducing output
Abrasive tools scratch the coating — once scratched, panels lose efficiency and warranty coverage
Walking on your roof is dangerous — falls are the #1 cause of home maintenance injuries
Wrong cleaning solutions void warranties — most manufacturers require deionized water only

We use deionized, purified water and soft brushes specifically designed for solar panels. No chemicals. No scratching. No risk to your warranty.

Our Solar Panel Cleaning Process

System Inspection

We check your panel layout, wiring, mounting hardware, and overall condition before touching anything.

Deionized Water Wash

Using our water-fed pole system with purified, deionized water, we gently remove all buildup without ever stepping on your roof or touching the panels with harsh tools.

Spot Treatment

Stubborn bird droppings, tree sap, and mineral deposits get individual attention with panel-safe soft brushes.

Final Rinse & Report

Every panel gets a final rinse for a streak-free finish. We photograph before and after so you can see exactly what we did — and track your production improvement.
