A pyranometer is a sensor that converts the global solar radiation it receives into an electrical signal that can be measured. ... Instead, a pyrgeometer is used to measure long-wave radiation (4 to 100 µm). Pyranometers must also account for the angle of the solar radiation, which is referred to as the cosine response.
Why do use pyranometer and its uses?
A pyranometer is a type of actinometer used for measuring solar irradiance on a planar surface and it is designed to measure the solar radiation flux density (W/m2) from the hemisphere above within a wavelength range 0.3 μm to 3 μm. ... A typical pyranometer does not require any power to operate.
What is a pyranometer used for?
In the solar energy industry pyranometers are used to monitor the performance of photovoltaic (PV) power plants. By comparing the actual power output from the PV power plant to the expected output based on a pyranometer reading the efficiency of the PV power plant can be determined.
