COMPARISON OF VARIOUS TYPES OF ROOFTOP GRID CONNECTED SOLAR PLANTS: A CASE STUDY
Journal Title: International Journal of Electrical and Electronics Engineering Research (IJEEER) - Year 2017, Vol 7, Issue 2
Abstract
The growing electrical energy demand in developing countries like India has triggered the scientists and engineers to think of new and innovative methods in the field of renewable energy sources especially solar energy. Grid connected PV systems have become the best alternative to bulk electrical power consumers like industries and other institutions. In this paper 280kWp Photovoltaic grid connected power plant commissioned at CVR College of Engineering is taken for research study. This plant uses three mechanisms to trap the solar energy from the sun to produce electrical energy from the solar array. Out of three mechanisms, Single axis Polar tracking, Single axis tracking power plants produce more amount of electrical energy compared to seasonal tilt power plant. The energy outputs of Single Axis Polar tracking power plant and Single axis tracking power plant are compared from May '15 to September '16. After observing the energy outputs from each power plant, the entire 12 months of time in a year is divided into two time frames viz. from October to March and other from April to September. In one time frame Single Axis Polar tracking power plant is giving better performance whereas in other time frame Single axis tracking power plant is giving better output.
