Abstract

Abstract

To evaluate the solar radiation measurement data and instrument specifications, the new versatile laboratory test facility for solar radiation instruments has been developed. It consists of an available solar simulator and a rotating mechanism with an instrument mount. The spectral distribution is in accordance with Air Mass 1.5 global spectral conditions. Directionally, tilt and non-linearity errors of pyranometers can be tested by using this facility. Satisfactory results have been obtained according to calibration measurements of pyranometers. It is shown that the difference values of the sensitivity are within the range of ±0.6% measured in the outdoor exposure.
