Dust on solar panels can reduce energy output by up to 25% in desert regions and up to 100% during dust storm events. Our patent-pending, self-cleaning technology removes dust from solar panels and regains up to 98% of lost energy. The technology is based on proprietary electrodes that generate electric fields to sweep away dust from solar panels.

After conducting 180+ customer interviews we found that the current solution of using manual labor and water to clean solar panels is inefficient, expensive, and unsustainable. There is an urgent need for fully automated, scalable, and waterless cleaning technology. Based on theoretical calculations and experimental results the proposed new generation of Electrodynamic Shield (EDS) builds upon NASA’s heritage EDS technology recognized by the R&D 100 Award. Inspired by NASA and develop on its heritage EDS technology, we advanced it to terrestrial applications. SuperClean Glass Inc. has developed novel highly transparent (99%) electrodes, which use 10X less power and exhibit negligible light losses as compared to previous generations of EDS technology. Our target market is utility-scale solar installations in desert regions, where water is a scarce resource. The technology is projected to save $72 million in energy and cleaning cost, and 38 million gallons of potable water over the 25-year lifetime of a solar panel for the 100MW utility-scale solar installation. The technology is based on electrostatic force, which repels dust from the solar panel. More specifically, when a voltage is applied to the electrode, a strong electric field charges the dust particles and then repel them away from the electrodes. The efficiency of cleaning is proportional to the charge acquired by the particles and the intensity of the electric field generated by the electrodes. In addition to the solar industry, our technology is relevant to architectural, automotive, aerospace and military applications.
