Introduction to Sensor
The PV Soiling Monitoring Sensor is designed to monitor dust and pollutant accumulation on solar panel surfaces and assess their impact on PV power generation efficiency. Using blue-light pollutant measurement technology, the device measures the proportion of soiling and estimates the reduction in sunlight reaching the solar modules.
