Pyranometer calibration: leveling errors and cosine effect
Conference
·
OSTI ID:7310865
The solar monitoring system for the Sandia Total Energy Systems Test Facility consists of a fixed, horizontal pyranometer and a tracking pyranometer and pyrheliometer. Readout uses a scanned A-D converter with recording via print-out, magnetic tape, or disk. The Eppley pyrheliometer is calibrated by direct comparison with a Kendall electrically-calibrated radiometer. The pyranometers, model PSP, also from Eppley, are calibrated against the pyrheliometer using shading techniques; and the parameters affecting that calibration are the subject of this summary.
