Sun-X secures patent for PV sensor that measures soiling, yield loss

Germany-based Sun-X says it has patented a soiling sensor for PV modules that accurately measures dirt levels, determines yield loss, and assesses optimal cleaning times. From pv magazine Germany Germany-based Sun-X has secured a patent from the European Patent Office for a sensor that detects soiling levels on PV modules. The Sunsoric sensor uses a light source that shines over the PV module's surface. Dust and dirt particles on the glass reflect light differently compared to a clean pane, and a receiver diode captures this difference for calculation. According to Sun-X, the sensor's algorithm ...
