Silicon Irradiance Sensor

Stop of production since 30. June 2017

The production of the SiS sensor was stopped on 30. June 2017. Please use our Si sensors.

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.

We have been manufacturing various types of Si sensors since 1994. So far, we have sold several 10,000 sensors worldwide.
