Description
- Build as solar module – easily comparable to energy yield and system performance of PV systems
- Optional cell temperature as alternative to directly measured module temperature
- Output signal: 0 … 10V for irradiance and cell temperature
Silicon irradiance sensors show a cost-effective, but rugged and reliable solution for irradiance measurement. Based on the construction of the sensor element corresponding to a PV module they are ideal as reference for 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.
