"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.”
