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 solar power 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 solar/ photovoltaic (PV) panels required to achieve the desired power. The output power from the solar panel is dependent on solar irradiance and temperature. In order to extract more power from the solar panel it is necessary to operate the PV panel at its Maximum Power Point (MPP). In this paper a solar power based lead acid battery charging is implemented using DC-DC converter and MPPT algorithm. This may be useful to drive the wheelchair at outdoor by harnessing the solar energy. © Research India Publications.
