Energy generation is the leading factors for progress of all countries of the world and recently many countries are exploring new alternative sources of energy to minimize carbon footprint and costs . Solar energy is the best option as it can be Quickly installed and dismantled, Suitable solution for remote areas, cheapest as well as harmless. This is getting most popular and growing mean of energy in most developed countries of world. Many countries are applying solar device and start relying on it as an alternative sources of energy generation.
Surface of the Earth receives 174 petawatts (PW) from solar radiation. Approximately 30% is reflected back to space and the rest is absorbed by earth. Renewable energy is the fastest-growing energy sources in world by increasing 2.5 percent annually and solar is third most important renewable source of power generation. Photovoltaics and Solar thermal energy are two main techniques being used for producing solar power. The global photovoltaic volume reached 136 GW (+35%) by the end of 2013, enough to produce 160 TWh/year and can meet 0.85% of the power need of the entire world. According to Wikipedia, top five Countries of world on the basis of their estimated total photovoltaic peak power capacity in 2013 is shown in map.
