SOLARBRUSH is a robotic cleaning system for solar power plants. Cleaning of solar panels is important as they lose efficiency due to deposits, such as sand and dust. Huge layers of sand on the panels lower the output in many regions, according to studies about 30% of energy is lost in a single month in arid regions. The same problem applies to mirrors used in solar towers CSP technology. The SOLABRUSH robot walks on solar panels with a high inclination of up to 35 degrees. The robot is light weight and wireless as it carries a rechargeable and replaceable battery. Either one or more robots can be placed on separate arrays to clean the solar panels as they have the capability to move from one panel to another.
