Abstract: The population of whole world is increasing, so the requirement of electricity is also increasing, that’s why we have to produce more electricity. But the whole world is looking for clean environment and sustainable development and it is need also because of this we are going towards renewable energy sources for generation of electricity. Use of solar PV system is increasing in all over the world, because of its potential to reduce the energy consumption form traditional sources and to decrease the air pollution. Life cycle assessment (LCA) it is a study of impact on environment by technology or product in its whole life (form beginning to end of life). In this paper we did LCA on 100kw rooftop solar PV system. It is placed in MITS Gwalior (M.P.). We find out Embodied energy, energy payback time (EPBT). Total annual energy.

Keywords: LCA, (EPBT), Embodied Energy, Energy analysis, Annual energy.
