SOLAR ENERGY UTILIZATION IN INDIA

UTILIZATION OF SOLAR ENERGY:                        

Solar energy is most economic in low power application. It has many advantages like Eco friendly and abundantly available energy source in nature. It can be converted into useful electrical energy in cost effective manner. In recent year our government also focused for renewable energy sources in India. Solar energy is one of the most important green energy is on focus due to the increasing price of crude oil in International market, and environment point of view.

India is such a country in which there are such a remote and under-developed area, where it is nearly impossible to give grid connection due to many reason. So, there are only photovoltaic inverter system is only the most economic way to fulfilled their energy requirement and make like simpler and convenient.

Taking this view with mind we are going to design and built model of solar inverter, using light dependent relay. This is the system which can give power in day and night without any difficulties. It also additionally gives the provision for charging external battery. Solar panel harnessing the solar energy from Sun. And the battery is used to store the energy. Since most of the application is run on AC power. So, inverter circuit is required to convert the DC power to AC power.

Finally we design a modified square wave inverter, which gives Square wave as output from inverter circuit. Then by using filter circuit we modified square wave into Trapezoidal wave, which reduces the harmonics than that of square wave. Relay driver circuit is used for the smooth operation of the solar inverter. It can supply power 24 X 7. Really driver circuit connect the battery and inverter circuit directly from solar Panel for both charging the battery and power output from the inverter. In night time when solar panel stop working it cuts the connection from solar panel and battery is connected to the inverter that it can give continuous power in night time also without any difficulties. At last we combine the both circuit and solar panel as a source and as a whole it becomes a solar inverter. Output of the inverter is 12 volt AC 50 Hz, so we used a step up transformer to up the voltage to 230 volt
