The active solar energy harvesting techniques by using the Photovoltaic cells, which converts the solar energy directly into the Electric Energy. The energy harvesting from the Sun is required so that maximum utilization can be taken. In this paper, a model which extract the maximum power of photovoltaic module and increases the efficiency of the overall system in terms of power generated by the photovoltaic module is compared with previously proposed models. All the techniques and concept required and used to design the model are explained and the results are shown in comparative form. The comparison of results shows that a model designed by using dc-dc boost converter with incremental conductance algorithm have maximum power.
