INTRODUCTION orldwide, power sector provides 18,000 terawatt-hours of electric energy every year, around 40% of world’s total energy use. In doing this it produces more than 10 gigatonnes of carbon dioxide every year, the largest sector contribution of humanity’s fossil-fuel derived emissions [1]. Obviously, the easiest way to cut the carbon released by electricity generation is to increase efficiency of electric appliances and electric systems. But there are limits to such gains, and there is the familiar paradox that greater energy efficiency can lead to greater energy consumption. Thus, the response to reduce emissions released by electricity generation and reduction of climate change must involve a move to decarbonizing power sector and using carbon-free sources of electricity. This requires serious thinking about the extensive use of new and renewable energy sources and technologies such as solar and wind. . II. SOLAR ENERGY Solar energy is a vast and largely untapped resource. The World Energy Council estimates the earth’s surface, on average, has the potential to capture around 5.4 GJ (1.5 MWh) of solar energy every year. Solar energy accounted for 0.1% of the world’s total primary energy consumption in 2007, although its use has increased significantly in recent years [2]. By end of 2012 the cumulative installed capacity of solar PV system exceeded 102000 MW in IEA member countries alone [8]. This was about 1400 MW at the end of 2000. This has been shown in Fig. 1. According to this figure, installation of solar PV system has been growing at an annual average of more than 25% since 2000. Fig. 1 Cumulative PV Capacity MW Solar PV technology converts sunlight directly into electricity using photovoltaic phenomena. PV systems can be installed on rooftops, integrated into building designs, or scaled up to megawatt scale power plants. PV systems can also be used in conjunction with concentrating mirrors or lenses for large scale centralised power. The amount of solar energy incident on the world’s land area far exceeds total world energy demand. Solar energy thus has the potential to make a major contribution to the world’s energy needs. However, large scale solar energy production is currently limited by its high capital cost. The cost issues related to solar energy has always been a major negative point for solar energy in general and solar photovoltaic in particular. Increasing manufacturing capacity has led to remarkable reduction in cost of solar PV electricity, but the PV electricity production cost is still far above the electricity price from conventional energy technologies. This price difference is very high particularly in those countries, where price of electricity from conventional power plants is relatively low. Government policies investment costs and risks are projected to be the main factors underpinning future growth in world solar energy use [2]. Solar energy, although expensive but it has the potential to play a crucial role in the world’s energy supply, now and in the future. The last five years has been a period when PV energy changed from being a small-scale contributor to energy supply to being a more substantial one, and the next five years look like being a period when the technology could have an even more substantial impact. Cost calculations show that even in sunniest place it is impossible for PV to be able to compete with conventional electricity without reasonable government subsidies or reasonable fee-in tariff. Solar radiation is intermittent because of daily and seasonal variations. However, the correlation between solar radiation and daytime peak electricity demand means that solar energy has the potential to provide electricity during peak demand times. Photovoltaic systems are well suited to off-grid electricity generation applications, and where costs of electricity generation from other sources are high (such as in remote communities). Relatively high capital costs and risks remain the primary limitation to more widespread use of solar energy.
