The favorable climate conditions of the place called Belakavadi of Mandya district in the state of Karnataka and the recent legislation for utilization of renewable energy sources provide a substantial incentive for installation of photovoltaic power plants. In this paper, the grid connected solar photovoltaic power plant established by Karnataka Power Corporation Limited, is presented, and its performance is evaluated. The photovoltaic power plant has asolar radiation of 5.26 kWh/sq.mt/day spread over 25 Acres of land. Operating module temperature varies from 15 to 40 degree centigrade, with a tilt angle of module 15 degree and guaranteed energy generated is 8.3224MU/Annum with 19% CUF. The plant has been in operation since 2012. The power plant is suitably monitored during 7 Months, and the performance ratio and the various power losses (temperature, soiling, internal, network, power electronics, grid availability and interconnection) are calculated. The final yield (YF) ranged from 1.96 to 5.07 h/d, and the performance ratio (PR) ranged from 58 to 73%, giving an annual PR of 67.36%.
