Solar Panel Cleaning with Powerhouse Northwest
Solar panel cleaning is a specialized maintenance service that removes dirt, dust, bird droppings, pollen, moss, algae, lichen, and other debris from photovoltaic panels using gentle, safe methods—typically chemical free, deionized or purified water, soft brushes, and low-to-no pressure (often pure water systems or soft washing techniques) to avoid scratching glass surfaces or damaging seals.
In the Pacific Northwest's wet, moss-prone climate, buildup can reduce efficiency by 15-30%, lowering energy output and ROI on your solar investment. Regular professional cleaning restores peak performance, boosts electricity production, prevents long-term damage or hot spots, extends panel lifespan, and helps maintain warranties.
