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 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 we have 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 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 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.

Measure the impact soiling has on your solar panel production

The RST Cleantech Solution works on solar systems of all sizes.


Over 1 million panels every day. That's over 800 solar panels every minute – or over 13 solar panels every second.


The only cost-effective solution to panel soiling. Maximizes panel production and minimizes operational costs.

The RST Cleantech Solution is an automated solar panel cleaning system designed to increase solar energy production and preserve your panel warranty. The system uses filtering technologies and advanced water engineering to treat water scaling and corrosion found in water sources around the world. It is designed and developed in accordance with the solar panel manufacturers’ warranties and maintenance guidelines – and it is one of the only solar panel cleaning systems in the world that is completely green. We don't add chemicals and avoid all chemical by-products.

Increases Production

Minimize soiling losses through weekly cleaning. Improve your solar production significantly.


The system is fully automated – no more people on roofs or property.


Our patented system is based on tried and tested drip irrigation technology – almost no moving parts.

Protects Warranties

Soft, pure water cleans at night to avoid thermal stress on panels. No chemicals, abrasives or high pressure.

Proven Technology

Launched in 2011 and now installed on more than 2,000 projects worldwide.

Remotely Controlled

For commercial systems, you can control when your panels are cleaned via the RST CleanTech App on your smartphone.
