Abstract
Background: In this article, the potential applications of the solar photovoltaic thermal system have been discussed. The increasing cost and rapid depletion of conventional energy, researchers are optimizing the use of solar energy in residential and commercial purposes—the scope of solar energy, providing an alternative for residential and commercial power requirements. The average power requirement of a residential house is calculated with the help of power ratings. Hourly, daily, and monthly power requirement is calculated for designing the optimum size of solar photo voltaic thermal.Results: A stand-alone solar photovoltaic thermal system has been designed. For the sizing of the solar photovoltaic thermal system, meteorological data are collected through Synergy Enviro and PVWatts Calculator. The mathematical calculation and simulation study has been performed to estimate the expected power generation from the PVT. The cash flow and payback period of PVT are calculated. The total cost of installation was rupees 114450/- and the payback period was 9 years approximately.Conclusions: The forecasted output of solar photovoltaic thermal has been calculated based on solar radiation value obtained from different sources. The significant finding of the present study are: The maximum and the minimum electrical load was approximately 7.7 kWh per day in summer and about 2.5 kWh per day in winter. The maximum and minimum solar radiation at the installed site was 7.08 kWh / m 2 / day and 3.32 kWh / m 2 / day. The maximum electrical power calculated by installed solar module is 2466 kWh per year.
