New Pyranometer Comes with 99 Years of Experience

Eppley Laboratory Inc (USA) has been providing custom-built precision solar measurement solutions since 1917. Recently, they launched their new GPP Pyranometer.

Pyranometers are used to measure the total energy from the sun. When levelled in the horizontal plane, this is called global horizontal irradiance (GHI); when positioned in a plane of a PV array, it is called total irradiance in the plane of array (TPA). Inverted, a pyranometer is used to measure the reflected or albedo irradiance (ALBEDO). A pyranometer can also be shaded from the direct beam of the sun to measure the diffuse horizontal irradiance (DHI).

With the same performance characteristics as the ISO 9060 Secondary Standard SPP Pyranometer, the GPP was custom built for the PV industry to provide an ideal solution to include in your weather station measurements at a fraction of the cost.
