Swish Solar

Solar panels lose up to 60% of their efficiency from sand and snow buildup. Current cleaning methods are expensive, water-intensive, and often ineffective, wasting billions of liters of water every year. Most solar farms are still cleaned on fixed schedules rather than when it’s actually needed, leading to millions in lost potential revenue and unnecessary operating costs. Swish Solar is building the ecosystem for efficient and sustainable solar. Our Swish film is a self cleaning nanotech film that removes sand and snow without water or moving parts, restoring lost efficiency. Paired with SwishOS, our AI platform that analyzes soiling and determines the optimal cleaning schedule, we help solar operators maximize energy yield and revenue. We are making solar energy smarter, cleaner, and truly sustainable, unlocking the full potential of renewable energy worldwide.
