By This SolarTidy customer from Oceanside, CA lives in a region where’s there’s a lot of nearby construction. In the before picture, we noticed a thick film of dust and residue on the panels that were definitely impeding solar output. After our ProPlus Di-Ionized cleaning treatment, the panels shined with brand-new clarity. In fact, this treatment will last 10 times longer than traditional cleaning methods and allow your panels to operate at their maximum capacity, optimizing their efficiency so you can receive the most financial benefits from your investment.
