Estimation of system efficiency and utilisation factor of a mirror integrated solar PV system

Abstract

This study presents the investigation of benefits obtained in a mirror integrated standalone photovoltaic (PV) test system of 0.3 kW capacity. The enhancement of energy extraction is possible only through fixing the mirror at an optimal angle facing towards the PV panel. Hence, the optimal condition for the maximum energy extraction in a year at a specific location is derived and presented considering the total irradiation falling on the panel. A detailed estimation on performance indices and feasibility analysis for the mirror integrated solar PV system (MISPVS) is carried out for one year from May 2018 to April 2019 for the test system with and without mirror arrangement. The total energy generated from the MISPVS during the monitoring period is found to increase from 359.10 kWh to 468.10 kWh which is around 130.3% when compared with the traditional solar PV system (TSPVS). Finally, the experimental results show that the system efficiency and capacity utilisation factor of the proposed system is enhanced to 13.09 and 17.81%, respectively.

“…Another experimental investigation was recently carried out in India on a mirror integrated PV system (MIPVS). It is concluded that the MIPVS system produces a 30.3% enhancement in yearly energy output compared to the conventional PV system (Odungat et al 2020). Amanlou et al investigated theoretically using CFD, an air-cooled LCPV/T system with a new design concave-side walls diffuser.…”
