This paper focuses on the energy aspect of photovoltaic (PV) modules. The distribution of radiative energy, temperature, and the thermal potential across the different layers of the PV modules are determined to carry out the comparative analysis of the modules. Based on these parameters, qualitative as well as quantitative evaluation of the PV modules are performed. The objective of this study is to examine the current technologies and suggest some methods based on the energy analysis on how to make the PV modules thermally effective. Results show that the glass made (non-framed) modules are more susceptible to thermal potential rather than the framed modules. The fluctuation of the cell temperature is marginally high for the amorphous silicon module surface. In contrast, the polycrystalline silicon module is, to a moderate extent, dormant to the thermal potential of the juxtaposed surfaces. Without taking any reservation, the smaller modules pose significant surface resistance to the incoming radiation. Unlike the framed modules, the dissipation of heat is relatively low in the glass nonframe modules. The heat received by the cells is significantly high in the glass non-framed modules (Duna Solar and Solar Watt), although it can be mitigated by increasing the thickness of EVA. It is assumed that the energy transport between the layers of the modules is through heat radiation rather than only conduction.
