What is heat transfer in a photovoltaic panel?
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.
Do Dusty PV panels have a higher heat transfer coefficient?
