In photovoltaic (PV) power plants, dust accumulation on solar module glass drastically diminishes power output. Our advanced DustIQ system employs cutting-edge blue light pollutant measurement technology. It is meticulously engineered for seamless installation within PV arrays, seamlessly integrating into power plant management ecosystems to guarantee improved operational efficiency. Positioned strategically on the PV panel frame, this innovative device precisely measures sunlight reduction caused by pollutants through accurate assessment of the soiling ratio (SR).
This revolutionary system empowers operations and maintenance teams to pinpoint crucial pollutant levels, enabling the timely initiation of essential cleaning procedures. Designed for maintenance-free operation with synchronized cleaning alongside surrounding components, it adheres to the rigorous IEC 61724-1 standards, offering precise multi-point measurements across vast photovoltaic parks. Compared to its predecessors, this system is extraordinarily cost-effective in terms of procurement, installation, and maintenance, making it an economically advantageous choice.
