Calculating Heat Transfer of Photovoltaic Panels

Click For Summary
SUMMARY

The discussion focuses on calculating the heat transfer value of photovoltaic panels, emphasizing the importance of material properties and environmental conditions. Key factors include the thermal conductivities of the materials involved and the type of heat transfer—whether it is between solids, solid to liquid, or solid to gas. The conversation highlights the necessity to consider conduction and convection processes, as well as the temperature dependence of the heat transfer coefficient.

I am doing a photovoltaic experiment and I wanted to know if anyone knew the heat transfer value of a photovoltaic panel or how to calculate it.

That depends on the materials (and their thermal conducitivies) and the environment. Is this heat transfer between solids, solid to liquid, or solid to gas (e.g. air). Then one must consider whether there is conduction or convection (solid to moving liquid or gas). The heat transfer coefficient may be temperature dependent.
