Modeling of Photovoltaic Array

Day-by-day the energy demand is increasing and thus the need for a renewable source that will not harm the environment are of prime importance. Some projections state that by 2050 the energy demand will triple. Yet majority of the energy requirements is satisfied by fossil fuels but by the use of photovoltaic systems could help in supplying the energy demands. In this project we have dealt with problem that persists with the modeling of photovoltaic device. The problem that various models of photovoltaic device face is the number of unknown parameters which are not mentioned in the datasheet. Various methods have been proposed in order to determine these unknown parameters. Basically, in this project, two of the proposed methods are being studied and then compared. This can give a brief idea to the manufacturers who design power electronics products about the easy-to-use modeling methods that can be used in simulation of photovoltaic arrays
