A megawatt scale grid-connected photovoltaic power plant was commissioned on 27 December 2009 in
Yalesandra in Kolar district in Karnataka. The Yalesandra plant is one among more than 20 such Megawatt
size solar power plants in India during the past few years. The performance of this plant during its first
year of operation has been discussed. The total electrical energy generated by the Yelasandra plant during
2010 was 3.34 million kWh. Although the performance of photovoltaic modules was good, there were problems
associated with the inverters which led to reduction in energy generation. The impact of temperature
variation of modules on their performance has been highlighted
