A V-trough PV system with polysilicon cell array and super cell array has been constructed and tested. Open-circuit voltage, short-circuit current, output power, fill factor and influence of temperature on V-trough PV concentration system have been analyzed. The results indicate that the output power of 10 pieces of polysilicon cell array is 6.198W and it is 1.21 times as that of non-concentration condition. Maximum output power of V-trough PV system with water cooling increase to 8.28W and power increment rate reach 62.67% compared with the non-concentration PV system. For the super cell array with no water cooling, the maximum output power of V-trough PV system varies from 7.834W to 14.223W. The results of this work provide some experimental support to the applications of the V-trough PV system.
