Solar power is one of the current leading renewable energy sources with the potential to change power grids large and small. Solar energy collection can lead to high operation temperatures which can be detrimental to the performance of the solar cells. A current area of study explores methods of recovering the heat dissipated by these modules. Phase change materials (PCMs) offer additional energy capture through latent heat storage. These substances can be incorporated into a number of heating and cooling applications. In this study, beeswax and coconut oil were chosen as the PCM because they are sustainable materials and their composite offers suitable thermal properties for solar panel application. A heat exchanger with a PCM layer was built and placed between two simulated solar panels, a geometry that has not yet been explored in literature. This system was compared to an alternate method with a simple water to water heat exchanger. The heat transfer to the water reservoir with the PCM heat exchanger did not show a significant improvement in heat recovered with respect to the water to water system. Further iterations of this design with a smaller volume of wax may produce a more desirable melting profile due to a decrease in thermal resistance caused by the wax. While the wax composite displayed a capacity for latent heat storage, the shear volume of wax needed for this geometry likely overpowered these effects. However, this experimental design is a promising arrangement for heat recovery from two solar panels simultaneously.
