Adler Realty Investments

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.
