    The solar industry’s dirty little secret. Your solar panels could be producing up to 30% more energy

    What happens to the panels after they are installed? And how do you optimize solar panel performance? Those topics are often merely an afterthought in the solar industry – but they shouldn’t be.

    When modelling future solar performance, solar professionals account for several losses – the most severe being soiling losses (when dirt accumulates on the panels and lowers production). Designers often accept soiling losses as inevitable and see no reason to discuss it. It is the dirty little secret of the solar industry.

    We are here to let the secret out: It is possible to minimize soiling losses and get up to 30% more energy production out of your panels – and our solar panel cleaning service system is the solution.

    RST CleanTech is the first technology to economically minimize soiling losses and improve production. The secret is out! There is no need to let dirt on your solar panels waste your money anymore. Want to know more about panel soiling?

    Find out how much your PV system is affected by soiling

    If you want to know exactly how much production your solar power system is losing due to soiling – and learn when the most cost-effective time to clean your solar panels is – check out Fracsun’s ARES Soiling Measurement Station.

    Fracsun is the industry leader in solar operational efficiency, and their ARES Soiling Measurement Station measures the effects of soiling loss on PV systems in order to optimize performance.
