摘要
Abstract
Power generation costs of photovoltaic (PV) systems and area of solar photovoltaic materials were reduced with concentrating a large amount of sunlight onto the area of solar photovoltaic materials to generate electricity by using a low concentrator. The double V-trough low concentrator PV systems were designed. By using the sun-tracking system and the data acquisition system, the characteristics of conventional single silicon sun PV modules such as short-circuit current, open-circuit voltage, maximum power were investigated under different working conditions. The temperature rising of PV modules was resolved by installing the radiator under PV modules. The experimental results show that with the double V-trough concentrator the output power from PV modules is increased by 27% ; the short-circuit current is increased by 25% ; the open circuit voltage and fill facto are little changed; the surface temperature of PV modules is elevated to 44. 8 t. The power output of PV modules can be increased by using double V-trough low concentrator PV systems, which provides an effective method to reduce costs of PV systems by using simple and reliable concentrators.关键词
