ABSTRACT
In the years to come the need for energy will increase manifold while the reserve of conventional energy will deplete in rapid pace. To meet the growing demand of energy harnessing of non-conventional / renewable energy is the necessity. Among all the available non-conventional sources, solar energy is the most abundant and uniformly distributed. Solar powered car is thesystem with the efficient utilization of solar energy designs a general purpose vehicle by charging battery using solar energy and especially designed for physically challenged & senior citizens. The existing system receives maximum sun energy only from 11 am to 2 pm, because always the solar collector kept at 30 degrees and charges a small battery. A new method is developed, where sun light is tracked from morning 6 am to 6 pm by moving the solar collector along with the movement of the sun using stepper motor based on ATMEL Microcontroller and multiple batteries can be charged one after another. When this system is implemented, at least30% extra energy can be created compared with the existing system.By this SOLAR POWERED CAR FOR PHYSICALLY CHALLENGED USING EMBEDDED TECHNOLOGY, the transportation is made more simple, easy and eco-friendly. The system is the improved system to provide higher efficiency for lower cost.
