Fossil fuels like coal, gas, diesel etc., used for generate electrical energy are in exhaust stage and causes pollution. This necessitates alternative sources of fuels which are renewable and non-pollutant like wind, solar, tidal to generate electrical energy. These renewable fuels cannot be supplied to generate power as required like conventional fuels, as they are naturally available and depends on environmental conditions. Hence they have to be efficiently utilized when they are available. Solar energy is the electromagnetic waves in the form of light which contains packets of energy known as photons. These photons produce electrical energy by the process known photovoltaic effect. In this paper studies are made to utilization of solar energy to produce electrical energy, for this sun-earth angular relation was found using declination angle of earth based on day number, azimuth angle, altitude angle, angle of incidence for particular location i.e., Andhra university, Visakhapatnam with latitude 17.680° N and longitude 83.320° E. Collecting radiation data for the consider site and calculating actual radiation on tilt surface by applying correction to the data collected. Simulation of solar photovoltaic panel using five parameter model of cell considering top Indian manufactured Solar Panels and estimating output DC power by using location Radiation, temperature and wind as input. Comparing output of simulation with on-line simulators like PV watts and off-line software’s SAM, PVs yst. Second part of this paper is estimation of installation cost of solar power plant, cost of generations, Performance ratio, Capacity utilization Factor, LCOE, return of investment, comparing with conventional utility rates.
