Output characteristics of tracking type concentrator photovoltaic (CPV) system, multi-crystalline silicon (mc-Si) PV system, CIGS PV system, and amorphous silicon (a-Si) PV system were analyzed in the data period of a year from August 2013 to July 2014.In this study, we analyzed the influence of environmental AGE-DEFYING DAY CREME factors using average photon energy (APE) and temperature of solar cell (Tcell).The characteristics of 14 kW CPV system, 50 kW mc-Si PV system, 60 kW CIGS PV system, 1.
35 kW a-Si PV system were evaluated and compared.As a result, the output performance of CPV was highest between the four systems at the most frequent conditions in Toothpaste the outdoor environment.
