在模拟太阳辐射强度为200 ~ 1000 W/m2、不同环境温度、自然对流和强制对流条件下，对聚光比为100 × 100的点聚焦菲涅尔透镜聚光器（FPVC）的热损失进行了广泛的室内实验研究。从实验程序中发现，太阳能电池的温度与模拟的太阳辐射的增加成比例地增加所有的实验测试，表明传导和对流传热显着大于长波辐射传热内和从FPVC系统。对于模拟的最坏情况，其中在模拟的1000 W/m2的太阳辐射强度和50°C的环境空气温度下测试FPVC系统，没有强制对流，FPVC系统中的预测硅太阳能电池效率降低到标准测试条件下的大约一半。
An extensive indoor experimental characterisation program to investigate the heat loss from a point focus Fresnel lens PV Concentrator (FPVC) with a concentration ratio of 100× was performed for a range of simulated solar radiation intensities between 200 and 1000W/m2, different ambient air temperatures, and natural and forced convection. From the experimental program it was found that the solar cell temperature increased proportionally with the increase in simulated solar radiation for all experimental tests, indicating that conductive and convective heat transfer were significantly larger than the long wave radiative heat transfer within and from the FPVC system. For the simulated worst case scenario, in which the FPVC system was tested under a simulated solar radiation intensity of 1000W/m2and ambient air temperature of 50°C with no forced convection, the predicted silicon solar cell efficiency in the FPVC system was reduced to approximately half that at standard test conditions.
