The LP Silicon-PYRA 04. pyranometer measures the global solar radiation (W/

m2) by using a silicon photodiode (400nm-1100nm).

The special geometry and the diffuser allow to have a pyranometer field of view

of 180 degrees according to cosine law.

The pyranometer is suitable for the measurement of natural sunlight. Under

conditions of overcast sky or measures reflected light is recommended to use a

thermopile pyranometer (model LP PYRA 03 or LP PYRA 02).

The LP Silicon-PYRA 04 pyranometer can be used in measurements of solar

radiation in the field of renewable energies such as solar thermal and solar

photovoltaic.
