This project report presents a numerical analysis of heat transfer in a photovoltaic panel. The temperature which a PV module works is equilibrium between the heat generated by the PV module and the heat loss to the surrounding environment. The different mechanisms of heat loss are conduction, convection and radiation.
In the present investigation, the effect of the inlet velocity of coolant air and the heat flux exerted on the panel are considered to evaluate their effects on the heat transfer coefficient and temperature of the backside of the photovoltaic panel is studied.
The results showed that the convective heat transfer coefficient of PV panels first increases and then decreases with the increase of dust accumulation density. And the average heat transfer coefficient of dusty PV modules is slightly higher than that of clean PV panels by 4.13%.
Since cooling has a great influence on the efficiency of solar panels, the convective heat transfer through this type of solar panel is investigated at the present study. Consequently, investigations on the thermal behavior of such designs are of importance.
This paper evaluates the photovoltaic (PV) module operating temperature’s relation to efficiency via a numerical heat transfer model. The literature reports that higher PV module operating temperatures impact PV module efficiency. There are dozens of explicit and implicit equations used to determine the PV module operating temperature.
The effect of different outdoor air temperatures on the rear-panel heat transfer is minimal. When the air velocity was 5 m/s and the outdoor air temperature was 10–40 °C, the heat transfer in the Poly Crystal Solar panel was calculated as 11.6 W/m2 K.
