Abstract - Generation of electricity by conventional sources
created a lot of pollution and it strained our natural resources like coal, etc. World’s main focus is to somehow find an alternative to these conventional sources. There are numerous methods to extract energy from non-conventional sources like sunlight, wind, biomass, water and geothermal etc., but power generation from Sunlight has emerged as one of the most successful programs in the renewable energy sector and has started making meaningful contributions to the overall power requirements of some states. Solar power is good renewable, clean and free source of energy of power production. In this work, our main objective is to do the cost analysis of solar energy system and its feasibility to produce required quantity of electricity for GZSCCET Campus. The whole GZSCCET Campus like Boys hostel, girls hostel, cafeteria, lecture halls, workshops, labs etc. have been surveyed and the data of electrical utilities and electricity consumption per month is collected. Hence GZSCCET can produce its own electricity for its whole campus and can become a bold example in India’s campaign for clean energy and development.
Key Words: Solar Power, Sustainable Development, Location Selection, Solar Panels, Rooftop solar power plant.

INTRODUCTION
The prime requirement to do any work is Energy. Till late 90’s the world had been using conventional or nonrenewable resource like coal, petroleum, etc., to fulfill their energy needs. But these resources posed a serious threat on the environment. The second drawback of conventional resources is that they may get extinct in a short time. So the only choice we are left with is to find an alternative. The substitution to the non-renewable resources is the promotion of renewable resources like solar energy. Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaic cells, solar thermal energy, and artificial photosynthesis. Solar techniques used now a day’s includes the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy of sunlight .Solar energy is an important renewable energy source for the country, both in the generation of PV electricity and as heat. Therefore, it is necessary to quantify the solar potential of an area, but to achieve this goal © 2017, IRJET

requires an adequate estimation of solar radiation incident on the Earth's surface. Generally, the spatial variability of solar radiation is determined by the interplay of chronological, geographical, atmospheric and surface conditions [1]. However, there are simple geometric formulas that allow a relatively reliable estimation, so the spatial modeling of this variable is crucial to quantify the availability of energy per area unit for its potential use. The solar radiation modeling has shown significant progress in recent decades, reaching at present integration in geographic information systems that allow quantification at its spatial distribution [2]. Solar power is set to play an increasingly significant part in future energy system of India. Solar energy is a free, renewable resource. So, no matter how much of it is used today, there will be still the same supply in the future. Solar energy is also a source of clean, non-polluting electricity. Unlike conventional power plants, solar plants emit no pollutants or green house gases. So today government as well as private sectors also prefers to produce large amount of electricity with its solar plants. Energy is a major input for overall socio-economic development. Use of fossil fuels is expected to raise the level of economic development process of a majority of the world population during the next two decades. However, up to 2020-2050, fossil fuels are likely to reach their maximum optimal potential, and the price of these fossil fuels will become too high than other renewable energy as they are limited and exhaustible energy resources. Therefore, renewable sources are expected to play a major role in accelerating sustainable growth and development in the second half of the next century, accounting 50-60% of the total global supply then. Solar plants are used for their mechanical power, solar power as an alternative to fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation, and uses little land. Sunlight is an inexpensive source of electricity, competitive with or in many places cheaper than coal or gas plants.
1.1 SOLAR POWER SYSTEM STRUCTURE AND WORKING PRINCIPLE We can change sunlight directly to electricity using solar cells. The sunlight hit solar panels on the roof with photons (particles of sunlight). The solar panel converts those photons into electrons of direct current ("DC") electricity. The electrons flow out of the solar panels and into an ISO 9001:2008 Certified Journal
