N2 - Outdoor I-V curve measurements have been made on all 189 Solarex SX-146 modules that were operated for five years in a mirror-enhanced, grid-connected photovoltaic system in the Negev desert of Israel. The modules have taken on a distinct yellow-brown coloration colpared to their original "blue" appearance, a phenomenon that has been observed in systems in other parts of the world. Although no original performance figures are available for comparison purposes, some indirect measurements are reported which enable one to conclude that the power output of this ensemble of browned modules has probably degraded at an average rate of about 1% per year.
