Impact of Spectral Irradiance Distribution and Temperature on Concentrator Photovoltaic System

Article Preview

Abstract:

The output characteristics of concentrator photovoltaic (CPV) system were analyzed in the data period of a year from November 2010 to October 2011. Characteristics of CPV are more sensitive to environmental factors as compared to flat-plate PV system. Especially, solar spectrum distribution has considerable influence on the output of CPV because CPV uses multi-junction solar cells. In this study, we analyzed the influence of environmental factors using average photon energy (APE) and temperature of solar cell (Tcell). Most frequent condition during operation was APE = 1.87 ± 0.005 eV and Tcell = 65 ± 2.5 °C. Performance ratio at the most frequent condition was 83.9%. These results indicated the importance of the understanding of the behavior of the outdoor performance and the accurate data of environmental conditions where the PV systems were installed.
