Seven Sensor 3S-SMS-MB Automatic Soiling Sensor
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, which is suitable for commercial, utility, industrial and rooftop projects, notifies the user of production losses due to soiling. If soiling ratio read from the sensor is 10%, it means that there is 10% energy loss in the facility.
