Radhika Vaid, Vaibhav Maheshwary, Sharang Mittal Abstract The development of renewable energy for the generation of electric power has been a critical topic in the current century with the growing problem of global warming and other environmental issues. Recently solar power has become a practical source for the generation of electricity worldwide. However the PV cell output is relatively low for commercial purposes. Thus, Maximum Power Point Tracking (MPPT) plays a crucial role in photovoltaic systems because they increase their efficiency by increasing the power output and reduces the cost by reducing the number of PV panels required to achieve the desired power. As the output power from the solar panel is dependent on solar irradiance and temperature, so in order to increase the power extracted from the solar panel it is necessary to operate the PV panel at its Maximum Power Point (MPP). In this research paper a solar power system is implemented using DC-DC converter and MPPT algorithm to charge the lead acid batteries which is further used to drive the wheelchair.
