Deionized water, zero spotting or residue Warranty-safe soft-bristle equipment Roof crews trained on fall protection Production reporting before and after "We manage several properties in Fremont and AG has been reliable on every one. They work after hours and always send photos so we know the job was done right." Verified Google Review AG Windows and Gutters cleans commercial solar arrays for warehouses, office buildings, schools, agricultural sites, apartment communities, and solar carports across Fremont and the South Bay. We use deionized water and soft-bristle brushes that protect panel warranties while restoring output lost to dust, pollen, and bird droppings. ![Cleaning a rooftop solar array](/__l5e/assets-v1/f564ef2d-750d-46f4-93c1-92f3f15443e3/photo-solar-panel-roof-new.jpg) ![Solar panels after professional cleaning](/__l5e/assets-v1/18f0bbe2-7ccc-4ced-8859-a2d0f01d6eca/photo-solar-panel-after.jpg) ## Soiling Is a Line Item on Your Energy Bill Commercial arrays sit still for years while dust, pollen, agricultural drift, and bird droppings build a haze across the glass. Soiling losses of 10–25% are common in the South Bay, and on a large system that is thousands of dollars of production each year. Cleaning is one of the few maintenance items that pays for itself directly. We clean with deionized water and soft brushes, never detergents or high-pressure spray that can compromise seals and void manufacturer warranties. Crews are trained on rooftop fall protection and never walk on panels. ## Systems We Service Flat-roof commercial arrays, pitched rooftop systems, ground mounts, solar carports, and multifamily rooftop installations. We coordinate with facility managers and O&M providers on access and shutdown requirements. ## What's Included - Deionized-water rinse across the full array - Soft-bristle brushing for bonded soiling and droppings - Inspection for cracked glass, hot spots, and loose mounts - Removal of debris from racking and roof surface - Photo documentation of the array before and after - Scheduled recurring cleanings tied to your production data ## How It Works 1 ### Free Walkthrough & Quote Send us the property details or schedule a quick walkthrough.
