Your solar panels work hard every day, and to keep them running at peak performance, regular cleaning is a must. At Window Genie, we apply our proven 3-step cleaning process—backed by our streak-free guarantee—to make sure your panels stay clear and efficient. Over time, dirt, pollen, bird droppings, and other debris can build up on the surface, blocking sunlight and reducing your system’s output. In fact, the National Renewable Energy Laboratory reports that dirty panels can lose up to 25% of their energy production. Clean panels mean more power—and more savings.
