Energy plays a vital role in socio-economic development of any country. The available conventional resources for power generation are fast depleting and will not be enough to meet the energy demand. To meet the growing demand for energy and to reduce the environmental pollution, the world has to look to the green energy sources.
Solar energy is also the most important of the non-conventional sources of energy because of non-polluting nature and therefore, helps in lessening the greenhouse effect. Solar energy is the most readily available perennial source of energy.
Solar energy is already the energy source of choice in many applications where power is used and the user does not have the option of connecting to the local electricity grid. The real challenge's for the solar energy industry is to penetrate the markets where the user has multiple options.
