Silicon Irradiance Sensors
With Integrated Cell Temperature Measurement
Solar Irradiance Sensors offer a cost effective possibility to
control the energy yield of PV plants. Measuring the current
irradiance beside the energy production allows easily indication
of component failures.
Properties / Advantages
Behaviour like PV Module
Irradiance measurement matches well to PV
power production
Sensor element: Crystalline solar cell, 20 mm x
34 mm
Measurement range irradiance: 0 - 1400 W/m
High Accuracy by Temperature Compensation
Error of max. 8 % (FSR) at vertical light beam
and under standard test condition (STC)
