At present lots of research is being carried out to run the cars, and other vehicles like motorcycles on the solar energy by using photovoltaic cells. There are two options for using solar energy, an important form of the renewable energy source, as the fuel to run the cars. These are given below:
1) Cars running entirely on the solar energy using photovoltaic cars: These cars are similar to the electrical vehicles. In electrical vehicles the battery is used to run the motor, which is connected to the wheels of the vehicle. As the motor runs the vehicle also runs. In the electrical vehicles (EVs) the battery has to be charged from the electrical point on regular basis, thus it consumes electricity and one has to pay for these electricity bills.
In the vehicles running on the solar energy, the arrays of photovoltaic cells are mounted usually on the top. These cells convert solar energy directly into the electrical energy, which charges the battery installed in the car. Thus instead of the charging the battery from external electric point, in solar cars the battery is charged by the solar energy, which is collected by the photovoltaic cells. The solar energy is freely available so we don’t have to bear the cost of the fuel.
The electrical vehicle running entirely on the solar energy has number of advantages including being noiseless, and pollution free.
