The conventional energy sources like coal, petroleum and fossil fuels are limited in nature. About 55% of energy is produced by fossil fuels in India. And fossil fuels are limited in nature and are not long lasting. With the increase in demand of electrical energy, the alternative non- conventional energy generation technique is required. The generation of electrical energy through Sun is the best option. The day and night is periodic in nature. So, one can extract unlimited amount of energy from sun. The energy generated from the sun is called solar energy. The solar energy is generated with the help of photovoltaic cell which is also called PV Cells. The photovoltaic cell converts the light into electrical energy directly without any intermediate conversion step. Now days the solar energy is preferred over conventional fossil fuels generators. The solar energy is considered as green energy as it doesn’t create pollution and no mechanical parts are used in solar photovoltaic system. The solar photovoltaic system is 90% efficient for the first ten years and 80% efficient for the coming five years. The solar systems are equipped with battery sources to supply the load in night. In this way, if there is sunshine for seven to eight hours, the load can be supplied for complete 24 hours. To promote power system security or to avoid outage the solar systems are used. The Grid Tied solar system can also be designed, where in absence of sun; the power can be taken from grid. The wind speed, temperature, sunlight inclination are some of the parameters which decides the solar energy conversion efficiency. This project is focused on the case study of 8 KW solar photovoltaic system designing. Here, we focused on the location, environment, Solar Cell type, connection, protection and commissioning of the system. If wireless power transmission scheme will be developed in future, then solar panels will be installed in space that provides 24 hour unlimited green energy. The complete designing is done as per criteria decided by MNRE and CREDA.
