Increase income, reduce damage, extend lifespan The equation is quite simple. Less dirt means more yield. Those who clean regularly save real money! Losses in energy production due to dirt of approximately 3% - 20% are not uncommon. Regular cleaning maximizes the yield of your solar system and thus secures your refinancing. Extend lifespan Not only maximize yield but also lifespan. Many types of dirt are material aggressive and have a quality-reducing effect on the photovoltaic system. Dirt that affects the module for several years, becomes moist at night and hot during the day, attacks the solar glass and the seal much more strongly. Long-term dirt leads to material fatigue, glass corrosion, and deteriorated glass coating.
