Setup Instructions
Spectral Response and Calibration
An ideal pyranometer measures the entire solar
spectrum, 280 to 2800 nm. However, about 90% of
sunlight energy is between 300 to 1100 nm. Model
SP-110 is calibrated to estimate all of the shortwave
energy from sunlight. Apogee pyranometers are
calibrated under sunlight over amultiple day period
to a heated and ventilated Kipp & Zonen model CM21
precision reference radiometer.
