COMPARATIVE STUDY OF MAXIMUM POWER POINT IN BOTH FULL SUN RAYS AND CLOUDY WEATHER CONDITION BY MATLAB SIMULATION

Renewable energy is the alternative source of energy corresponds to the conventional energies to mitigate the power demand for large population in the world. Fuels available in the world are constant. After a few decades it will be unavailable for mitigating the large demand. On the other hand conventional energy is much more harmful for polluting the environment. So the world is concern with on alternative energy sources which are nonconventional energy such as wind energy, geothermal energy, tidal energy, hydro energy and solar energy. All of indicated sources of energies are more environmental friendly and infinite. However, this paper deals with the solar energy. In previous study, latest information on about solar energy conversion efficiency is only about 16%. So if it is possible to increase this efficiency to as high as possible then it will be more expected to all. For this reason the focus on this paper is to extract maximum power from the solar panel in different temperature condition. Here PV system is modeled and simulate to track maximum power point available from the system. This research work has been carried out with the modeling of solar panel and makes its approximation in both full sun rays and partial cloudy weather condition and simulate it using MATLAB coding. Finally the outcome of this work is mostly satisfactory and encouraging.
