Energy harvesting using the renewable energy sources has been an area of research for more than 3 decades. Extensive work has been done on the techniques and methodologies to increase the output levels of various sources of energy like wind, Geothermal, and PV. The work presented here contains the analysis and the design of Inverters, Boost converter and the MPPT. Furthermore an extensive survey of the Solar array manufacturers has been given for the economical analysis of a photovoltaic system for a load of 4 kW. The present scenario of renewable energy usage in Pakistan is also discussed in the light of present energy crisis in the country.
