The solar industry
has a dirty little secret...

...Your solar panels could be producing up to 30% more energy.

The good news is that it is possible to reclaim that lost energy (and profit) by minimizing soiling losses with our automated solar panel cleaning system.

RST NightWash™ is the first cost-effective technology to 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.

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

When modeling future solar performance, solar professionals account for several losses – the most severe being soiling losses (panels + dirt = lower energy production). Solar analysts don’t typically discuss soiling losses because they are seen as inevitable.

But ignoring dirt on your solar panels is like ignoring rain on your windshield – it is downright irresponsible. Hence why we deem it the “dirty little secret” of the solar industry.

But, the secret out: It is possible to minimize soiling losses and get up to 30% more energy production out of your panels – and RST NightWash™ is the solution. RST NightWash™ is the first technology to economically minimize soiling losses and improve production. Don’t let dirt mess with your solar panels anymore.

"We have had RST on our solar panels for over a year now. Our roof is steep, and previous cleaners were tearing up the shingles. The cleaners also made me nervous with unnecessary risks – I don't want anyone to get injured at my house. And because of the steep roof, our neighbors can easily see our panels. I love that my panels are always a clean black, especially since we are next to the freeway. The neighbors ask how I keep them so clean! Best of all, our true-up bill has basically been eliminated due to RST. I would highly recommend RST."

"My electrical load has increased over the years since getting several electric cars, and my true-up bill was getting larger and larger. The RST system really increased my production! Not only did it offset the additional electrical usage from charging, it also lowered my true-up bill. We are happy with the RST system."
Rick Deckman
"We have seen our monthly electricity bill drop a lot. My true-up bill will be much smaller this year because of RST. I am glad RST is protecting the panel warranty while also keeping people off my spanish tile roof. And being near a open grassland area, it feels good that I can run RST to ward off wildfires if needed."
Paul Teagle
"The RST system was more effective than we originally thought. We have had it operating for 4 months now – we were surprised how clean it has kept the panels with zero effort or hassle for us. It has required no maintenance and we can control the entire system from our phone. It has been great to see our panels looking clean and productive everyday."
