Overview

The RC22 is a compact PV reference cell optimized for accurate irradiance measurement in both monofacial and bifacial PV systems. It supports dual calibration at 1000 W/m² (STC) and 135 W/m² (BSTC), with auto-ranging high and low scales to ensure reliable front- and rear-side irradiance measurements.

Designed for easy installation, the RC22 features integrated mounting options for front or rear array mounting and a glass-to-edge design that improves water roll-off and reduces soiling. It uses an M12 five-pin connector with Modbus RTU communication over RS485 and is available with overmolded cables in multiple lengths. The IP67-rated enclosure ensures robust performance in outdoor environments.
