Analyzing the on-field performance of a 1-megawatt-grid-tied PV system in South India

In the near future, the power scenario across countries worldwide is expected to impact substantially on the solar photovoltaic system. This paper demonstrates the design and performance analysis of a 1000-kilowatt (kW)-grid-tied solar photovoltaic plant (PVP). The PVP is partitioned into four small solar PVPs of 250kW each, consisting of an inverter and a combination of solar panels arranged in series and parallel. For better characterisation of overall plant performance, the power-generating system (solar PVP) is analysed by considering several parameters. After monitoring the plant over a span of one year, the data-based information is compiled by adding some final conditions and relative results on the PVP efficiency. Results show the annual performance ratio average was 0.77.
