The paper shows a detailed analysis of the thermal performance of concentrating solar panels and the temperature increase due to concentrated solar radiation. This work proposes a configuration to reduce temperature rise, maintain good panel efficiency, and increase output power. The configuration is based on a sandwich structure including a phase change material (PCM), which absorbs the thermal energy excess generated by the concentrated solar radiation onto the PV panel. The PCM incorporates a heat exchanger consisting of metallic fins that distribute the absorbed heat into the PCM homogeneously, avoiding thermal gradients and the hot point creation. The new configuration shows promising results according to experimental tests for solar radiation above the standard maximum value of 1000 W/m2. A carried-out modeling process results in adjusting algorithms to the parameters involved in the study, which allows the prediction of PV module performance under variable concentrated solar radiation.

Keywords: Thermal performance, heat exchange, phase change material, solar radiation concentration
