Waterless Soiling Monitoring Stations for Solar Photovoltaic Plants
Waterless Soiling Monitoring Stations for Solar Photovoltaic PlantsSI Case #M17-153P BackgroundSoiling is a phenomenon that occurs when dust and other particles stick to the active surfaces of solar cells. This decreases the amount of sunlight contacting the cells, which reduces the amount of current and resultant power reaching the power plant. Soiling is a major issue occurring in many climatic regions, especially in desert areas where rainfall occurs less often. In addition to reductions in performance, soiling in solar power plants is considered a major operations and maintenance expense by power plant owners. Therefore, there is a need for an efficient technology for monitoring the amount of energy loss due to soiling of the cells. Invention DescriptionResearchers at Arizona State University have developed a leading-edge monitoring station for calculating the soiling rate and energy loss for solar cells. This breakthrough station uses multiple sensors for comparison to one another, to gather data and diagnose soiling losses with increased accuracy regardless of location, tilt-angle, or installation style. Additionally, this highly efficient station requires no water or electrical connections. This clever monitoring station is also able to develop a custom cleaning schedule fully autonomously.
