Utilization of Solar Energy to make RF Based Remote Control Chair for Handicapped

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. In cities of India one of the major medium of transportation is auto rickshaws, which is producing a huge amount of air pollution as well as greenhouse gases like CO2. Fuel, which is used, is a non-renewable source and also which costs high as a result of that transportation charges increases. It would also affect the economy. Thus they should go for a reliable source as know that current trend of using the reliable source like solar which is available in plenty in country like India. This car using the solar panel, controller and DC motor setup to convert the light energy as an electrical energy which is fed to the DC motor to obtain mechanical motion. The system is the improved system to provide higher efficiency for lower cost. Solar powered car is the system with the efficient utilization of solar energy designs a general purpose vehicle by charging battery using solar energy and especially designed for physically challenged. 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.
