Advantages of Concentrator Photovoltaic System in High Solar Radiation Region

摘要

Concentrator photovoltaic (CPV) systems are promising power generation systems for their high outputs per module active area and rated power compared with crystalline silicon photovoltaic (Si-PV) systems. In a field test conducted in Morocco, where solar radiation is high, our CPV system demonstrated approximately 2.5 times higher output power per module active area and 1.3 times higher output power per rated power than a Si-PV system under the condition of direct normal irradiation of 7.9 kWh/m2/day. We have developed a tracker that faces the ground during the night, thus preventing soil or sand from accumulating on the glass surface of the CPV module and contributing to high power generation.
