A pyrheliometer mounted on a solar tracker is used to measure the Direct Normal Solar Irradiance (DNI) from the sun. Historically, the preferred field of view for Pyrheliometers was based on a 10:1 ratio which equated to approximately 5.7º. Due in part to the commercialization of the Eppley AHF Cavity Radiometer as a Primary Standard ...
  • Spectral Range: 250 - 3500 nm
  • Sensitivity: 8 μV / Wm^-2
Data Sheet
A pyranometer is used to measure the total energy from the sun. When leveled in the horizontal plane, this is called the Global Shortwave Irradiance (GLOBAL) and when positioned in a plane of PV Array, it is called the Total Irradiance in the Plane of Array (TPA). Inverted, a pyranometer is used to measure the Reflected or Albedo ...
