Modeling and Simulation of Solar Photovoltaic Module Using Matlab / Simulink

One of the major concerns in the power sector is the day-today increasing power demand but the unavailability of enough resources to meet the power demand using the conventional energy sources. Energy is the prime mover of economic growth and is vital to the sustenance of a modern economy .Future economic growth crucially depends on the long-term availability of energy from sources that are affordable , accessible and environment. Demand has increased for renewable sources of energy to be utilized along with conventional systems to meet the energy demand. Renewable sources like wind energy and solar energy are the prime energy sources which are being utilized in this regard. The continuous use of fossil fuels has caused the fossil fuel deposit to be reduced and has drastically affected the environment depleting the biosphere and cumulatively adding to global warming. Solar energy is abundantly available that has made it possible to harvest it and utilize it properly. Solar energy can be a standalone generating unit or can be a grid connected generating unit depending on the availability of a grid nearby. Thus it can be used to power rural areas where the availability of grids is very low. Another advantage of using solar energy is the portable operation whenever wherever necessary. In order to tackle the present energy crisis one has to develop an efficient manner in which power has to be extracted from the incoming solar radiation. The power conversion mechanisms have been greatly reduced in size in the past few years. The development in power electronics and material science has helped engineers to come up very small but powerful systems to withstand the high power demand. they can hardly compete in the competitive markets as a prime power generation source. The PV module represents the fundamental power conversion unit of PV generator system. The output characteristics of PV module depends on the solar radiation ,the cell temperature and output voltage of PV module. 2. PV MODULE
