Pyranometers are sensors that measure solar irradiance. There are two types depending on the operating principle:
- Thermopile Pyranometers: detect that portion of the solar spectrum corresponding to the range of 300 – 3000nm. They are more suitable for meteorological uses.
- Photovoltaic Pyranometers cell (Silicon Irradiance sensors or PV reference cell): detects the portion of the solar spectrum in a range of 350 – 1150nm. Pyrometers with photovoltaic cell allow to calculate a P.R (Performance Ratio) of PV systems more accurately than the thermopile.
We manufacture both types of pyranometers; the description of each sensor indicates the class it belongs to (A, B or C) as required by the ISO 9060 and IEC 61724-1 standards.
