The electromagnetic radiation from the Sun is a vital energy source of our planet. The utilization of the solar resource by nature is phenomenal and serves as an exemplary source of inspiration. Photosynthesis feeds various biotic ecosystems by capturing the sunlight and converting it into chemical energy. It is the same energy which manifest in all sort of fossil fuels. The natural convective flows of the earth‟s atmosphere and the ocean currents were also driven by the solar inputs. Solar energy sustains life on earth by driving the water cycle. The dilute nature of the solar resource and its variability on earth surface makes it difficult to utilize by mankind. The thermal energy from the sun was harnessed by humans from time immemorial for simple applications like drying and salt production. The discovery of Photovoltaic effect paved way for direct conversion of solar radiation into electrical energy.
