Solar Panel Cleaning

Arizona is one of the best states in the country for solar energy, and thousands of homeowners across Greater Phoenix and the East Valley rely on rooftop solar panels to reduce their electricity bills and lower their carbon footprint. But solar panels only work at peak efficiency when they are clean. Dust, pollen, bird droppings, hard water spots, and storm debris accumulate on panel surfaces over time, blocking sunlight and reducing energy output by as much as 20-30%. At Runyon Construction Group, we provide professional solar panel cleaning and washing services for residential and commercial properties throughout Maricopa and Pinal counties. Our trained crews use purified, deionized water and soft-bristle tools to safely remove buildup from your panels without scratching the glass or damaging the protective coatings. We never use harsh chemicals or abrasive materials that could void your manufacturer’s warranty. Arizona’s desert environment is particularly hard on solar panels. Fine desert dust settles on panel surfaces daily, and monsoon storms leave behind mud and debris that bakes onto the glass in the summer heat. Bird droppings are another common issue, especially for homes near parks, canals, or agricultural areas. Even a small amount of shading from dirt or droppings can significantly reduce the output of an entire panel string due to the way solar cells are wired in series. We recommend cleaning your solar panels at least twice a year for most Arizona homeowners, and quarterly for properties in areas with heavy dust, nearby construction, or significant bird activity. Our team inspects each panel during every cleaning visit, checking for physical damage, loose connections, and signs of wear that could affect performance. Our solar panel cleaning process is straightforward and designed to protect your investment. We start by rinsing the panels with purified water to loosen surface debris. Next, we gently scrub each panel with non-abrasive pads to remove stubborn spots. A final rinse with deionized water ensures a streak-free finish that lets maximum sunlight reach the photovoltaic cells. We also clean the panel frames and mounting hardware, and we clear any debris that has accumulated beneath the array. Safety is a top priority on every job. Our crews are experienced working on rooftops of all pitches and materials, and we carry full liability insurance for your protection. We use proper fall-protection equipment and follow OSHA guidelines for all rooftop work. We serve homeowners and businesses across Chandler, Gilbert, Mesa, Tempe, Scottsdale, Queen Creek, San Tan Valley, Apache Junction, Casa Grande, Maricopa, and surrounding communities. Whether you have a small residential system or a large commercial array, we have the equipment and expertise to get your panels producing at their best. Clean solar panels are not just about energy savings. They also protect the longevity of your system by preventing buildup that can cause hot spots and premature cell degradation. Regular maintenance helps ensure your panels deliver reliable performance for their full 25-30 year lifespan. Contact Runyon Construction Group today for a free estimate on solar panel cleaning.
