Residential Irradiance Sensor

The Low-Cost Irradiance Sensor is designed to measure irradiance for residential, rooftop, or small-scale PV projects. While industrial, commercial, and utility-scale PV systems require advanced features and high-accuracy meteorological sensors, these demands are less critical for residential and small-scale applications. The cost of the sensor should align with the scale of the PV system, and SEVEN has accomplished this with the Low-Cost Irradiance Sensor. The measured irradiance data is transmitted to monitoring devices, data loggers, and other receiving units via the RS485 serial interface using the MODBUS RTU protocol.
