Production factor

"Our Calabasas office building has a great location in terms of freeway access and visibility, but that also translates into heavy soiling. Washing quarterly just wasn’t keeping production up where we wanted it. With RST, we’ve witnessed over 20% increase in production so far. I plan to include it in any future solar installations."

Adler Realty Investments, Woodland Hills, CA, was looking for a way to improve solar panel production. They saw an increase in panel production after cleanings – but production quickly reverted to pre-cleaned conditions. We installed the RST CleanTech solution on one of Adler Realty Investments’ solar sections, and after only six weeks, there was an average increase in production of 26.2% on the panels with the RST system.

Impact

  • Successful PILOT: RST installed a PILOT project with Adler Realty inOctober 2019. After three months, the increase in production was over 20%. Adler installed RST on their entire rooftop system in March 2020.
  • A busy fire season in Q3 2020 saw ash build up on the roof. Nevertheless, RST kept the panels clean, although weeks of cloudy weather hurt yearly production. 
  • 1743 kWh/kW production factor in 2020 despite the fires. The Adler rooftop system has 5-degree racking at an azimuth of 150. According to the PV Watts energy model, the production factor should have been 1524 kWh/kW. That's 14.4% better production. 
  • The RST system ran twice a week at 5:00 am for the full year. The water bill is estimated to be $70 for 2020.

Why RST CleanTech?

Over 10 years ago, we set out to solve one of the biggest problems facing solar – panel soiling. We wanted to find a way to keep panels clean, maximize energy production, protect panel warranties, and increase revenue for system owners.

We knew there had to be a way to achieve our goals that didn’t entail deploying thousands of bristle-wielding workers or robots onto high voltage solar arrays across the world. When we realized there wasn’t, we created one. Enter, RST NightWash™.

RST NightWash™ is a safe, cost-effective, and eco-friendly automated solar panel cleaning solution.
