Kipp & Zonen - DustIQ the novel soiling monitoring solution for solar panels

Soiling of the panel glass is one of the major problems in the rapidly expanding solar energy market, with the attendant loss of efficiency and reduction in performance ratios. Now, there's a new, simple and very cost-effective alternative. Based on Kipp & Zonen's unique Optical Soiling Measurement (OSM) technology, DustIQ can be easily added to new or existing solar arrays and integrated into plant management systems. The unit is mounted to the frame of a PV panel and does not need sunlight to operate. It continuously measures the transmission loss through glass caused by soiling, so that the reduction in light reaching the solar cells can be calculated.
