There is a pressing need to accelerate the development of advanced clean energy technologies in order to address the global challenges of energy security, climate change and sustainable development. Solar Photovoltaic is a key technology option to realize the shift to a decarbonised energy supply and is projected to emerge as an attractive alternate electricity source in the future. Globally, the solar PV grid connected capacity has increased from 7.6 GW in 2007 to 13.5 GW in 2008 and was 21 GW at the end of 2009. Similarly, annual solar PV production also jumped from 3.7 GW in 2007 to 10.7 GW in 20091 . The growth trend is continuing and is likely to explode once the grid parity is achieved.
