SOLAR PANEL CLEANING IN HOLLISTER

Dirty solar panels in Hollister can lose 15–25% of their energy output. San Benito Valley agricultural dust, valley winds, and bird droppings build up fast — and your inverter won't tell you why your bills are climbing. From $99.

Why Clean Solar Panels Matter

Even a thin layer of dust cuts panel efficiency significantly. In Hollister, agricultural dust from San Benito Valley farms and valley winds coat panels consistently — especially during harvest season (July–October). Studies show regular cleaning can restore 15–25% lost output — paying for itself in reduced electricity bills within months.

Our Cleaning Method

ORS Clean uses deionized (pure) water and soft brush techniques — no harsh chemicals, no abrasives, nothing that could scratch anti-reflective coatings or void your panel warranty. We work safely on rooftops and document condition before and after every clean.

How Often Should Panels Be Cleaned?

Hollister's agricultural surroundings and valley winds mean panels typically need cleaning 2 times per year. Homes near active farm operations or in windier corridors may benefit from more frequent cleaning during harvest season.

FAQ

SOLAR PANEL CLEANING HOLLISTER — COMMON QUESTIONS

Why do solar panels get dirty so fast in Hollister?+

Hollister sits in the San Benito Valley surrounded by active agricultural land. Fine dust from vegetable, grain, and hay operations is carried by valley winds and settles on solar panels consistently — especially during the July–October harvest season. Unlike rain-washable dust, this fine agricultural particulate bakes onto panels in Hollister's summer heat and requires deionized water and soft brushing to remove. Panels can lose 15–25% efficiency within a single season.

How much does solar panel cleaning cost in Hollister?+

Pricing depends on system size and roof access. Text (408) 476-3891 with your address and number of panels for a free quote within 30 minutes.

Will cleaning void my solar panel warranty?+

No. We use deionized water and soft brushes — the manufacturer-recommended cleaning method that won't scratch coatings or void warranties.

How much output will I recover?+

Most customers see a noticeable improvement within a billing cycle. Panels heavily coated with bird droppings or pollen can recover 15–25% of lost production.
