Solar Panel Cleaning
Professional solar panel cleaning using reverse osmosis and deionized water. Restore efficiency lost to dust, pollen, and bird droppings.
Dirty solar panels lose up to 30% of their charging efficiency. Dust, pollen, bird droppings, and hard water deposits build up on the glass and block sunlight from reaching the cells. You are paying for a solar system that is not producing what it should.
How we clean
We use reverse osmosis and deionized water to clean your panels. No soap, no chemicals, no scrubbing that could scratch the glass or void your warranty. The purified water breaks down dirt and rinses it away, leaving panels spotless with zero residue.
Why RO/DI water matters
Regular tap water in the Central Valley is hard. It leaves mineral deposits on your panels that are almost as bad as the dirt you just washed off. Our RO/DI system removes those minerals before the water touches your panels. When it dries, nothing is left behind. Just clean glass that lets maximum sunlight through.
How often to clean
In the Stockton area, dust, agricultural particulates, and pollen accumulate quickly. Most homeowners benefit from cleaning twice a year: once in spring before peak production season and once in fall after the dry, dusty summer. We offer a 12-month subscription plan with a 20% discount for regular customers.
Safe for your system
We do not use pressure washers on solar panels. High pressure can crack cells and damage seals. Our soft-wash system with purified water is the manufacturer-recommended cleaning method. Your warranty stays intact.
