用于太阳能光电水泵的菲涅耳透镜聚光收集器

报道了具有第二级Ｖ形槽聚光器的玻璃直纹菲涅尔透镜与ＬＧＢＧ高效太阳电池组成的低倍聚光收集器的试验结果。宽度为３０ｍｍ、长度为１．５８ｍ的太阳电池组件，经聚光后峰值功率从７Ｗ增大到４４Ｗ，比常规太阳电池费用减少６０％，系统总费用降低４０％。

FRESNEL LENS CONCENTRATING COLLECTOR FOR SOLAR PHOTOVOLTAIC WATER PUMPING

his paper presents the experimental results of a low concentrating ratio collector consisting of Fresnel lens concentrator system with second stage V-trough concentrator and high efficiency LGBG cells. It is reported that the peak power output of solar cell module with 30mm in width and l.58m in length increases from 7W of flat plate PV module to 44W of concentrating PV system. The cost of the concentrating solar cells decreases by a factor of 0.6 and the total cost of solar PV power system decreases by a factor of 0.4 comparing with normal flat plale solar PV power.
