"I’m glad that my installer recommended that we install RST. This area can get pretty dusty and manual cleaning wasn’t cutting it – the panels were just getting dirty a few days later. RST’s proactive cleaning system keeps the panels clean all the time. I highly recommend it to anyone looking to make the most of their solar investment."

“I’m more than glad that my solar installer recommended RST. Whenever I look at my panels, they’re clean. Farmers, peers, and everyone always ask how I keep my panels clean, and I tell them about RST. It’s not complicated. Cleaner panels produce more energy. Just down the road, I’ll see people manually cleaning panels without RST, a few days later and they’re already covered with dust – I never see that on mine.”

Solar Has A Dirty Secret

Your panels could be producing 30% more energy.

Panels get dirty over time, resulting in reduced energy production.

Solar is an excellent investment, that’s a fact. But the solar industry has a dirty little secret: Your solar panels could be producing up to 30% more energy.

The common narrative suggests that once solar is installed on your home or business, you don’t have to worry about upkeep for the next 25 years. Like most things that sound too good to be true, this isn’t.
