IMT Solar Irradiance Sensor

IMT Solar Irradiance Sensor
Irradiance Sensor (Si Series)
Irradiance Sensor (Si Series)
•Silicon irradiance sensors (Si sensor) show a cost-effective, but rugged
and reliable solution for the measurement of solar irradiance, especially
for the monitoring of Photovoltaic (PV) systems.
•Based on the construction of the sensor element corresponding to a PV module they are ideal as reference for the monitoring of PV systems.
•Especially the spectral response comparable to PV modules as well as the similar inclination error (incident angle modifier) allow an exact analysis of PV energy yields using Si sensor data.!

 

Advantages
• Built completely as a solar module, therefore extremely good comparability to energy yields and system performance of PV systems, temperature compensation for higher accuracy
• The optional cell temperature is a very good alternative to directly measured module temperature and leads to a higher accuracy in yield forecasting.
