Nunes and Sons Dairy

$23,000

Additional production

Year 1

Cash-flow positive

"Our RST NightWash™ system has already paid for itself with increased production. It’s a no-brainer investment for our operation. Our solar is producing more than I have paid to RST for the system. The system really doesn’t use much water at all, which is an especially important consideration right now."

In September 2021, RST NightWash™ was installed on the 836-kilowatt (KW) solar array located on Nunes and Sons Dairy in Tulare, California. Here we look at the impact RST NightWash™ has had in the 7 months since it was installed at this location.

Impact

Increased production

The 836 kW solar array has seen $23,000 of extra production compared to the same period the year before. The system is on track to deliver over $40,000 in extra production for the year.   

Cash-flow positive first year 

The value of the extra production amounts to more than the system owner has paid through RST financing, resulting in a net positive cash flow for Nunes and Sons Dairy.

Minimal water use

RST NightWash™ is able to deliver drastic production increases with minimal water use. With three cleanings per week at this site, RST NightWash™ requires about the same water needed to irrigate a single almond tree for a year.

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.
