In Glendale, CA, dust, pollen, and hard water mineral deposits settle on rooftop solar arrays and quietly cut into energy production, a challenge made worse by dense retail traffic, vehicle exhaust, and the dry Santa Ana winds that sweep down from the surrounding hills near the Americana at Brand, Glendale Galleria, and the hillside neighborhoods of Adams Hill and Verdugo Woodlands. Empire Pressure Washing uses purified water and soft brush techniques so panels come out clean without any risk of scratching the glass or voiding the manufacturer warranty. Regular cleaning keeps Glendale, CA solar systems producing at full capacity so homeowners get the energy savings they invested in, and every visit is backed by our licensed, insured, satisfaction guaranteed service.
