3M Anti-Soiling Technology Helps Increase Power Output in Photovoltaic Modules

3M will introduce an innovative new coating for photovoltaic (PV) modules and concentrated solar power (CSP) mirrors at Solar Power International, September 10-13 in Orlando, Fla. 3M™ Anti-Soiling Liquid is an easy-to-apply coating designed for aftermarket use that helps solar modules stay cleaner, longer. The product significantly reduces dry dust accumulation that often occurs on sun-facing surfaces. This helps increase light transmission to the photovoltaic cells and improve overall power output. Data has shown that modules coated with the 3M Anti-Soiling Liquid generate five to ten percent more energy than uncoated modules.

Designed for use during regular cleaning and maintenance operations, the liquid is easily applied with hand tools, is water-based, and is safe for both the environment and for workers with recommended application techniques.

“3M has performed extensive testing on this product — not just in the lab, but in the field as well. Customers will see that it delivers results in real-world conditions,” said Dr. Dan Chen, business development manager, 3M Renewable Energy Division. “We are proud to offer this pioneering product to the solar industry.”
