With cooled solar PV, the highest efficiency is about 7.32%, which took place at around 21 °C (surface temperature). Comparing two conditions between cooled solar panel and non-cooled solar panel with both under about 24 °C of ambient temperature, the efficiency increase rate is (7.32%–4.98%)/4.98% = 47%.
In this review study, the effect of cooling on the performance of PV/T solar panels has been categorized by assessment of the available literature. This review study is restricted to the cooling of PV/T solar panels.
The photovoltaic panel cooled by a water flowing is commonly used in the study of solar cell to generate the electrical and thermal power outputs of the photovoltaic module. A practical method is therefore required for predicting the distributions of temperature and photovoltaic panel powers over time.
