Performance Investigation of V-trough Concentrating PV System

设计制作了V型槽聚光PV系统,基于此系统对多晶硅电池阵列和空间太阳电池阵列进行实验研究。结果表明,V型槽聚光下多晶硅电池阵列的最大输出功率为6.198W,是非聚光下的1.21倍。空间太阳电池阵列的最大输出功率由未聚光时的7.834W增至聚光后的14.223W,提高了近一倍。采用通水冷却方法,研究了V型槽聚光下电池工作温度对电池阵列开路电压、短路电流、输出功率和填充因子的影响。聚光水冷后多晶硅电池阵列最大输出功率增加到8.28W,比普通光照下提高了62.67%.

The V-trough concentrating PV system has been designed.Experimental investigations of system performance with the polysilicon solar cell array and the Super cell array have been carried out.The results indicate that the maximum output power of 10 pieces of the polysilicon solar cell array is 6.198W,which is 1.21 times as that of non-concentrating condition.The maximum output power of the Super cell array is 14.223W which is nearly double to 7.834W.The influences of the open-circuit voltage,short-circuit current,output power and Fill Factor with cell temperature of the polysilicon solar cell array based on the V-trough concentrating system under water cooling condition have been analyzed.The maximum output power of the polysilicon solar cell array increases from 6.198W to 8.28W with growth rate 62.67%.
