DAkkS Calibration of Solar Irradiance Sensor as Reference Cell for PV Monitoring

Silicon Irradiance Sensor Precise Sensor with Higher Accuracy

Silicon solar irradiation sensors (Si sensors) offer an economical but robust and reliable solution for measuring solar irradiance levels, particularly for monitoring photovoltaic systems. The design of the sensor element, which corresponds to that of a photovoltaic module, make these sensors ideally suited as a reference for monitoring photovoltaic systems. The spectral sensitivity, which corresponds to that of photovoltaic modules, and the very similar incident angle modifier, enable a precise analysis of photovoltaic yields using measured values from the sensor.
Our precise Si sensors are the best choice for applications requiring a high degree of accuracy (utility-scale systems, PR guarantee, R&D).
Each sensor can be delivered with an ISFH standard calibration including DAkkS certificate .
