Modelling & Analysis of PV-array

As per the flow of time the energy demand is increasing and thus the necessities for a renewable source that won’t harm the environment are of prime importance. Some projections state that by 2050 the energy demand will triple. Now majority of the energy requirements is satisfied by fossil fuels but by the use of PV systems could help in fulfilling the energy needs. In this project we’ve deal with problem that persists with the modelling of photovoltaic devices. The problem that many different kinds of models of photovoltaic device face is the number of unknown parameters which aren’t mentioned in the datasheet. Various methods have been proposed in order to determine these unknown parameters. Basically, in this paper, two of the proposed methods are being studied and then compared. This effort can give a brief idea to the developers & manufacturers who design power electronics products about the easy-to-use modelling methods that can be used in simulation of photovoltaic arrays.
