| Popis: | Continuous Solar irradiation on the photovoltaic panel causes its temperature to increase, resulting in reduced efficiency. The present paper focuses on improving the efficiency of the photovoltaic panel through the use of hybrid Photovoltaic-Thermal (PVT) system. Water is used as the coolant in the cooling channel, flowing through the copper tubing provided below the photovoltaic panel, where the temperature is maximum. The thermal energy extracted in the process can be harnessed in several ways, improving the overall efficiency of the system. A theoretical model was prepared using COMSOL® multi-physics. The results achieved in the experimental set-up are quantified. As per the experimentation carried on the photovoltaic panel, an average temperature of 303.38 K at Standard Test Condition (STC) was achieved through cooling, while the temperature of the panel without cooling rose up to 333.15 K in environmental conditions, thus, improving the efficiency of the photovoltaic panel. The paper later applies the idea to an entire solar power plant to improve the overall efficiency of the power plant, by cooling the photovoltaic panel as well as generate hot water as its by-product. |
