Day-by-day the energy demand is increasing and thus the need for a renewable source that will not harm the environment are of major importance. Some projections state that by 2050 the energy requirement 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 power demands. In this paper we have dealt with problem that persists with the modeling of photovoltaic device. The disputed point where various models of photovoltaic device face is the number of unknown parameters which are not mentioned in the datasheet. Various methodologies have been proposed in order to determine these unknown parameters. Basically, in this work, two of the proposed methods are being studied and then related. 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. © Research India Publications.

Environmentally friendly technologies such as photovoltaic’s and fuel cells are DC sources. In the current power infrastructure, this necessitates converting the power supplied by these devices into AC for transmission and distribution which adds losses and complexity. Now-a-days, due to power failure, there is a great used for UPS systems in our homes or in workplaces and also the amount of DC loads in our buildings is ever-increasing with computers, televisions, and other electronics entering our workplaces. This forces another conversion of the AC power to DC, adding further low power ratings, losses and complexity. Due to low power rating of the system, it is very important to reduce number of converter stages and use the generated energy efficiently. Therefore, instead of using different dedicated converters from various uni-directional renewable sources, this paper proposes a single stage boost converter with multiple inputs that can efficiently decimate generated energy. The proposed converter works under various operating modes which are discussed in this paper. This paper proposes the use of a DC distribution system. © Research India Publications.
