A Numerical Analogy of Improving Efficiency for the PVT System in Bangladesh

Mathematical modeling of a three-dimensional PVT system is considered and solved using the FEM. Numerical simulation applied to explore influence solar irradiance on thermal energy, electrical power, total efficiency this system. Water HTF. The irradiance, inlet fluid mass flow rate, ambient temperature, partial shading are all chosen in range 200-500 W/m2, 30-180 L/h, 10-37 °C, 0-30%, accordingly based weather condition Bangladesh. effects temperatures cell output fluid, power efficiency-thermal efficiency, examined. results show that increasing each 100 W/m2 enhances outlet energy by 2.17 0.54 °C 20.7 113.3 W, respectively, devalues electrical, thermal, overall efficiencies approximately 0.17, 0.67, 0.83%, respectively. water temperature reduce almost 0.6 0.83 respectively; rise 0.30 3.07 escalate about 0.04, 0.4, 0.44% for every 10 L/h rate increment. Due increment increase 1.7 0.05 decreases 0.9 increases 9.89 reduces 0.1%.
