The electrical and thermal energy generated by a Photo-voltaic (PV) module is based on the amount of the solar radiation directed on the PV module. In this study, a Photo-voltaic Thermal (PVT) system is constructed to maximize the electrical energy generation through the fast removal of heat through a new phase layered topology. The combinations of aluminum plate and heatsinks are used to transfer heat generated by sunlight radiation on PV modules to heat transfer thermal container. The aluminum plate is attached beneath the PV module and heatsinks welded beneath the alumni plate making it as a phase layered heat removal. The heat transfer on each layer of the photovoltaic thermal system is investigated with the phase changing topology and also investigated for its performance with a heat removal agent. In both cases, with and without water as coolant in the thermal container, the experimental outcome is analysed for performance analysis. It is found the PV temperature reduced by about 10 degrees which is cirtical for the PV performance reducing the wasted thermal energy and thereby increases the electrical energy conversion.

Photovoltaic Thermal System

This study developed a thermal model of a photovoltaic thermal collector (PVT) to predict the performance and outlet temperature of the system. The PVT consisted of a polycrystalline photovoltaic module, a polymer collector–type sheet in a tube, and an insulator. The motivation of the present work is that the polymer materials are flexible, low cost and lightweight which are for the PVT applications. The outlet temperature of the PVT increased with the decreasing rate of mass flow into the riser because the water had sufficient time for thermal heating. One unit of polymer collector can achieve an outlet temperature of 69 °C at 500 W/m2 at a mass flow rate of 0.0063 kg/s.

Future Work

Solar energy is a viable renewable energy source, and photovoltaic technology has mature significantly in recent years. To maintain the operating efficiency of photovoltaic system, heat must be remove from its surface, thus lead to development of photovoltaic/thermal system. This paper identify several key design criteria as well as heat transfer enhancement methods that is currently existed, and some future work is proposed to optimize the system.
