Out of many renewable energy resources, solar energy is one of the conspicuous sources of energy which can supply the increasing demand of energy. As of May 2014, India has an installed PV capacity of 2.5 GW. The solar photovoltaic project includes power electronics with high quality performance devices, incorporated with smart energy management principles. Power electronics is used to improve the energy efficiency of apparatus, and help the generation of environmentally clean energy. In this article the explanation of role of power electronics and the discussion about similar and future concepts in solar photovoltaic systems related to reliability and advancement of each technology in India has been presented.
Today we are facing with various problems such as global warming, climate change, pollution, formation of greenhouse gases, increase in temperature, decrease in water table, water scarcity, and depletion of ozone layer. The price of fuel is also increasing simultaneously, that is why it becomes very difficult to generate power from conventional energy sources. Due to its pollution and greenhouse gas emission, the use of traditional energy resources such as fossils fuel is not justifiable. Energy demand is increasing rapidly. So there is a mismatch between generation and requirement, leading to load shedding problems in many parts of the world. To fight against this situation, we have to focus our attention on use of renewable energy sources. The integration of power electronics with renewable energy sources such as solar and wind has a vast potential to meet the energy scarcity of India. In its endeavor to promote the use of renewable energy, Ministry of Renewable Energy, Government of India is providing the subsidy for installation of renewable energy projects.
Most of the industries and corporate houses are coming forward to install more and more solar photovoltaic and wind power plants to meet their electricity requirement. Solar photovoltaic systems are becoming more popular compared to wind power plants due to availability of abundant solar irradiation throughout the year and decreasing cost of PV panels. In renewable energy projects, use of power electronics devices plays an important role. This paper discusses about the various solar photovoltaic systems integrated with power electronics, in India.
