Abstract –   The solar energy conversion into electricity is a very promising technique, knowing that the source is free, clean and abundant in several countries. With a strong commitment to increase the renewable sources based energy capacity to 175 GW by 2022, India has a target to install 100 GW of solar energy capacity. Of this 40 GW would be the share of grid connected solar PV rooftop. In this paper the performance of a Typical Domestic Rooftop Photovoltaic (RTPV) System through an experimental setup of 1.5kW RTPV installation in the subtropical climate of North India has been shown. Experimental setup was on the  hourly electrical readings taken over the different months of year 2021, it has been exhibited that the use of MPPT Technique along with a domestic PV installation, not only reduces the Energy Pay Back Time (EPBT) of the system, but it also increases the Electrical Production Factor (EPF) and Life Cycle Conversion Efficiency (LCCE) significantly.

A SIMULINK model of 780W RTPV system is also being designed and simulated to show the significance of MPPT Technique implemented by Perturb & Observe (P&O) algorithm; in terms of consistent power generation over a long operational time, which in turn reduces EPBT as well. This paper is written with an attempt to blow off economical barriers for the potential customers in North Indian market by integrating MPPT technique with a Conventional, Clean & Renewable Energy Generating system which lowers the EPBT period, allowing access to free and clean energy source in remote or/and rural areas of India in the smallest possible time after the installation.
