RK210-03 Dust Monitoring System for Solar Panel-Soiling Monitoring System
PRODUCT DESCRIPTION
The soiling on the glass of solar modules is the main factor affecting the power generation efficiency of PV power plants. The soiling monitoring device using blue light pollutant measurement technology can be easily installed in the PV array and integrated into the power plant management system. The device is installed on the frame of the PV panel and calculates the reduction in sunlight reaching the solar modules by measuring the proportion of pollutants (SR).
This allows operation and maintenance personnel to know when pollutants reach the critical point and decide whether it is necessary to start the cleaning process. The product does not require maintenance, only cleaning surrounding components in the same way. Due to the varying pollution rates of large photovoltaic power plants throughout the entire park, the IEC 61724-1 standard requires multi-point measurement. Compared to traditional products, it has much lower procurement, installation, and maintenance costs, making it more economical.
