Performance analysis of grid interactive solar photovoltaic plant in India

Solar Photovoltaic systems are widely accepted as alternate energy sources across the world. Grid Tied PV (GTPV) and Grid Interactive (GIPV) PV systems are the two configurations in which PV generation is integrated with Grid. Later is more complex due to inclusion of battery as storage and connected load, along with Grid import/export. In this paper, performance of a 40 kWp GIPV system, installed in India, is presented. The system under study comprises of PV, Grid, and Battery bank and connected load. Performance parameters like reference yield, array yield, final yield, performance ratio, and capacity factor are derived using standards IEC 61724. Also presented is Annual energy yield of the plant and Annual efficiencies of PV array, inverter and system. The effect of temperature on PV array and inverter performance is also evaluated. All these parameters are evaluated from real time annual data.
