Performance analysis of a 11.2 kWp roof top grid-connected PV system in Eastern India

TLDR

Rooftop solar installations are increasingly common worldwide, and this study examines an 11.2 kWp system on a 25‑metre building in Bhubaneswar, India. The paper reports the performance of this grid‑connected photovoltaic system during its first year of operation from September 2014 to August 2015. The system, tilted at 21°, was fed into the state grid and its performance was evaluated by measuring PV module efficiency, array yield, final yield, inverter efficiency, and performance ratio. Over the monitored period it produced 14.960 MWh, with a module efficiency of 13.42 %, inverter efficiency of 89.83 %, and a performance ratio of 0.78.

Abstract

Barren land and roof tops of buildings are being increasingly used worldwide to install solar panels for generating electricity. One such step has been taken by Siksha 'O'Anusandhan University, Bhubaneswar (Latitude 20.24° N and Longitude 80.85° E) by installing a 11.2 kWp grid connected solar power system during February, 2014. This PV system is tilted at an angle of 21° on the top floor of a 25 metre height building. This system was installed This paper presents the results of this grid connected photovoltaic system which was monitored between September 2014 to August 2015. The entire electricity generated by the system was fed into the state grid. The different parameters of the system studied include PV module efficiency, array yield, final yield, inverter efficiency and performance ratio of the system. The total energy generated during this period was found to be 14.960 MWh and the PV module efficiency, inverter efficiency and performance ratio were found to be 13.42%, 89.83% and 0.78 respectively.
