dc.description.abstractPhotovoltaic (PV) cells have the capacity to absorb up to 80% of incoming solar radiation, converting a part of this radiation into electricity. The power output of PV panels are rated at 25 C and an increase over this nominal operating cell temperature causes a decrease in the energy conversion efficiency of PV panels when compared to the rated power. With photovoltaic thermal (PVT) systems, it is possible to reduce the panel temperature and thus increase the electrical efficiency, and simultaneously obtain electrical and thermal energy. Various thermal collector designs used in PVTs have been studied experimentally and numerically in the literature. In the present study, a detailed literature review for such thermal collector designs was carried out and then a novel cooler design that is different from the designs existing in the literature was developed, manufactured and tested. The effect of the present design on the efficiency of the PVT system was analyzed experimentally and statistically. Experiments were designed by factorial design approach and carried out in laboratory conditions. Furthermore, a mathematical model was developed for the electrical and thermal efficiencies of the PVT system presently studied. Experiments were carried out at volumetric flow rates of 0.55 L/min, 1.1 L/min and 1.65 L/min and radiation values of 300 W/m(2), 600 W/m(2), and 900 W/m(2). The highest electrical efficiency of the PVT system was 17.69% at 900 W/m(2) and 1.65 L/min and the thermal efficiency 58.5% at 900 W/m(2) and 0.55 L/min. When compared with the electrical efficiency of the conventional PV panel at 900 W/m(2) radiation, it was observed that the electrical efficiency of the novel design increased by 4.67%. In addition, it was observed that the electrical efficiency decreased and the thermal efficiency increased with the increase of the panel temperature.en_US
