SEVEN Soiling Sensor is designed to measure the loss of energy production due to soiling caused by environmental factors on photovoltaic panels. The Soiling Sensor is used to know the production losses due to soiling. If soiling level read from the sensor is 10%, it means that there is 10% energy loss in the facility (PV Soiling = Energy Loss)
The measured Soiling Level is transferred to dataloggers and receiver units via a 2-wire RS485 bus with Modbus RTU protocol, and it is SunSpec compliant.
