Deciphering Solar Potential and Sustainability-A Comparative Study of Indian Subcontinent

India is experiencing an energy crisis due to the constraints of its current coal-based power plants. Considering the increasing demand for power, India needs to develop new and sustainable techniques for generating electricity. Many researchers are working to find alternative approaches of producing electricity without distressing the environment. Solar energy represents a potential solution to this enigma. Indian subcontinent is largely blessed with solar energy. The average value of solar irradiation incident is around 5,000 trillion kWh per year energy. One such method to extract this energy is to mount roof-mounted solar panels on the open roof tops of significant structures. Motivated by the increasing penetration of SPV plants, this paper illustrates the design of solar based DG according to the load requirement and SPV injection into the grid at four different locations of the Indian subcontinent. A comprehensive comparative analysis of the incurred loss percentage and performance ratio of the proposed SPV model at each geographic location has been detailed.
