flat-plate systems

Output characteristics of tracking type concentrator photovoltaic (CPV) system, multi-crystallin e silicon (mc-Si) PV system, and CIGS 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 factors using average photon energy (APE) and temperature of solar cell (Teell ). T he characteristics of 14 kW CPV system, 50 kW multi-crystallin e silicon PV system, 60 kW CIGS PV system were evaluated and compared. As a result, the output performance of CPV was highest between the three systems at the most frequent conditions of outdoor environ ment.
