Analysis of measured photovoltaic module performance for Florida, Oregon, and Colorado locations

Losses from AOI effects were from 2½% to 3%; losses from PV module temperature were from 2.3% to 10.8%; and low-light-level effects ranged from a loss of 7.4% for a CIGS PV module deployed in Eugene to a gain of 0.3% for a CdTe PV module deployed in Cocoa. Spectral effects also appeared to be present, with increased performance of the CdTe modules and a-Si PV module in Cocoa and decreased performance in Golden.
