Abstract The assessment of performance indices of a 3 MW utility-scale ground-mounted grid-tied solar farm located in Northern India is carried out in this work. RealTime SCADA data of energy generation and other input parameters are utilized to evaluate performance indicators like Performance Ratio, Capacity Factor, efficiencies, losses, etc. The real-time and simulation results of the considered performance indicators are presented for the period from 1st January 2018 to 31st December 2018. The values of PR, CF and energy loss obtained are 80%, 16.35% and 19.42%, respectively. Among temperature, wind speed and level of accumulation of dust particles, ambient temperature is the most influential parameter that affects the PV performance in the considered region. The performance indicators estimated using PVSYST specifically for the detailed analysis of energy loss utilizing the three-stage conversion approach. The obtained estimated results are found to be in line with the actual values. These results could serve as a guideline for the application of solar PV in the northern part of India and in other countries with similar climatic conditions.

Introduction The modernization and development of every nation are linked with the pace in bridging the gap between supply and demand of electrical energy; however, global warming concerns have reached an alarming stage. To achieve the goal of energy demand without production of greenhouse gases, renewable energy is the only solution. There are plenty of renewable energy resources available, but solar energy is widely available in abundance [1–3]. India has good potential for solar energy because of its location. It is around the equator with around 300 clear days [4]. It has around 200 MW/km2 average solar radiation; theoretically, 12.5% of the total Indian land is available for the solar energy absorption and may produce approximately 5000 trillion kWh. To harness a fraction of the available solar energy, India had planned to achieve 20GW production by
