Calibration of pyrheliometers and pyranometers for testing photovoltaic devices
Technical Report
·
OSTI ID:5612928
The status of pyranometer and pyrheliometer calibration techniques was reviewed. The intercomparison of absolute cavity pyrheliometers is discussed. A round robin experiment performed to isolate various aspects of calibration methods suggests that a much more rigorous approach is required for calibrations of pyranometers to be employed in solar device testing. Tilt effects, however small, deviation from cosine law, and temperature related responsivity, can cause errors in the assessment of efficiency of solar devices. The importance of absolute cavity pyrheliometer intercomparisons, is demonstrated.
