"I'm thoroughly impressed by these production results. Before installing RST NightWash™, I was convinced that cleaning my panels twice a year would sufficiently address soiling losses. This was far from the truth. Now that my system is optimized with RST, I get to enjoy 23 years of increased production, while avoiding all the logistical headaches of manual panel cleaning."
