Title: Use of Pyranometers to Estimate PV Module Degradation Rates in the Field: Preprint

This paper describes a methodology that uses relative measurements to estimate the degradation rates of PV modules in the field. The importance of calibration and cleaning is illustrated. The number of years of field measurements needed to measure degradation rates with data from the field is cut in half using relative comparisons.
