This comprehensive assessment findings show that a Paraffin-based phase change material cooling approach can cope with a greater drop in solar photovoltaic module temperature ranging from 3 to 26.6 °C, which stimulates an increase in module electrical efficiency ranging from 1 to 56 %.

By utilizing nanofluids for cooling PV modules, the heat dissipation capabilities can be significantly improved, leading to lower operating temperatures, increased energy production, and prolonged lifespan of the modules.

In the present research, to improve the photoelectric conversion efficiency of PV panels, RT25 paraffin wax was used as the cooling PCM, and the effect of adding fins to strengthen PCM heat transfer on the heat-dissipation performance of the PV/PCM system was investigated.

PCM possesses the unique ability to store and release thermal energy during phase transitions, effectively dissipating heat and preventing excessive temperature rise in the PV panels. By implementing PCM panels, the overall solar energy conversion efficiency of the PV system can be significantly enhanced. 9–11.
