Dual Reference Cell Soiling Measurement Kit
Easily calculate the soiling ratio with RC22 reference cells. The clean cell should be cleaned 2-3 per week for accurate irradiance measurements. These sensors communicate via the Mobdbus RTU protocol. Power requirements are 10-30 VDC.
Mars Soiling Sensor
This sensor uses patented technology to see soiling particles on the sensor window and does not require any dust-specific calibration. The internal image processing calculates transmission loss due to soiling. This sensor is specifically designed for low-cost, maintenance-free measurement of PV soiling, with no on-site staff.
RC22 PV Reference Cell
This compact sensor is optimized for both monofacial and bifacial PV. The RC22 is accurate at low and high irradiance. The sensor communicates via Modbus over RS485. Power requirements are 10-30 VDC.
