The PV/T hybrid system is a combined system consisting of PV panel behind which heat exchanger with fins are embedded. The PV/T system consists of PV panels with a battery bank, inverter etc., and the thermal system consists of a hot water storage tank, pump and differential thermostats. In the present work, the modeling and simulation of a Solar Photovoltaic/Thermal (PV/T) hybrid system is carried out for 5 kWp using TRNSYS for electrical energy and thermal energy for domestic hot water applications. The prominent parameters used for determining the electrical efficiency, thermal efficiency, overall thermal efficiency, electrical thermal efficiency and exergy efficiency are the solar radiation, voltage, current, ambient temperature, mass flow rate of water, area of the PV module etc. The simulated results of the Solar PV/T hybrid system are analyzed for the optimum water flow rate of 25 kg/hr. The electrical efficiency, thermal efficiency, overall thermal efficiency, equivalent thermal efficiency, exergy efficiency are found to be 10%, 34%, 60%, 35% and 13% respectively. The average tank temperature is found to be 50°C.

The energy yield of the photovoltaic (PV) system is reduced to a greater extent under shaded conditions. Reconfiguration and repositioning techniques demand more number of sensors, switches, and an efficient control algorithm and are well suited for rapidly changing shade conditions. However, for fixed shading that is common in urban rooftop installations, where the shading is partial and usually caused by nearby structures, a simple, yet effective technique is necessary. This paper addresses the issue by grouping the panels based on shade intensity and the merits of asymmetrical multilevel inverter (AMLI) are utilized as the working voltage of each group is different.
