Performance Analysis of a Grid-connected High Concentrating Photovoltaic System under Practical Operation Conditions

High concentrating photovoltaic (HCPV) is a promising technique for the practical commercial utilization of solar energy. However, the performance of a HCPV system is significantly influenced by environmental parameters such as solar direct normal irradiance (DNI) level and environmental temperature...
