Solar Home Systems as the Basis for Bottom-Up Grids

Abstract

People living in India's rural areas still have no access to electricity. According to the ministry of new and renewable energy (MNRE); this count is more than 400 million people (47.5%). While there are still more than 2.3 billion people in the world without reliable access to electricity. Due to remoteness of these places; it is not possible to give the supply from the central grid. Many area are hilly or forest or deep forest. It is not feasible as well as economical to lay the lines in such areas. The environment constraint of polluted air and water are on the verge of explosion. To avoid all the mentioned constrain the renewable energy sources are the most appropriate. These sources are environmental friendly as well as easy to erect. This paper present the DC operated system model for standalone application with and without battery. The analysis has been made for excess energy produced by solar PV system.
