太阳能的集中增加了光伏（PV）表面上的照射通量，因此需要较少的PV材料。一种新型的非对称复合抛物面光伏聚光器已被实验表征与类似的非聚光系统。不同数量的光伏串连接在系统内进行了分析，并测量了1.62的功率比相比，类似的非聚光光伏板具有相同的电池面积。非聚光板和聚光系统分别实现了8.6%和6.8%的太阳能到电力转换效率。聚光系统中光伏的测量平均太阳能电池温度仅比具有相同电池面积的类似非聚光系统高12°C。
Concentration of solar energy increases the illuminated flux on the photovoltaic (PV) surface thus less PV material is required. A novel asymmetric compound parabolic photovoltaic concentrator has been characterised experimentally with a similar non-concentrating system. Different numbers of PV strings connected within the system have been analysed and a power ratio of 1.62 measured compared to a similar non-concentrating PV panel with the same cell area. The solar to electrical conversion efficiency of 8.6% and 6.8% was achieved for the non-concentrating panel the concentrating system, respectively. The measured average solar cell temperature of the PV in the concentrator system was only 12°C higher than that of the similar non-concentrating system with same cell area.
