Ever thought how cheap will travel become once cars use sun as the fuel? Are you also wondering about a fuel that is cost free and is abundantly available? Wait no more! A concept which was once unimaginable has been picking up progress as people have started realizing solar energy’s benefits. They have realized the importance of saving the environment and truly understood sustainable development. This is the only reason why people have been trying to invent a solar car for so long now. From 1970s itself, people have been trying to build a solar car. The ability of human mind is fully depicted when we talk about solar cars.

Solar energy is a renewable source of energy and it shall never end. Hence, it must be fully exploited. Solar cars in one way protect non-renewable resources like fossil fuels which will help the environment grow.

A solar car is a car which runs on sun’s energy. Photovoltaic cells (PVC) are used in cars to harness sun’s energy. These cells come in direct contact with the sunlight and store the energy which they receive from the sun. A semiconductor, known as silicon, is used to trap or absorb energy from the sun. Then there is a flow of electrons which generates electricity. This stored energy can be later used to run vehicles. It depends on the size and type of photovoltaic cells that how long the car will run. The more expensive the cells, more energy will they store. One very important thing about them is that they can be used with unnatural light. However, when used with unnatural light, the speed and the mileage will be very low as compared to solar energy.

The work done so far on PVC is considerable. However, even as of now they are very bulky and a bit unreliable. Car’s mileage is also dependent on the weight of the car. More the weight less shall be the mileage. So, it is of due importance that solar cells are designed in such a manner that they are not heavy, yet they are efficient.

The solar cars are definitely going to be in high demand due to rising prices of petrol and gas. Petrol and gas are also very difficult to be extracted from land. They are also non-renewable sources of energy and will definitely finish some or the other day. Solar cars are in their nascent stages and need a lot of work to be done to use solar cars in an efficient and effective way. With new and upgraded solar cells being produced, there is a complete assurance that solar cars will replace the traditional cars.

The future of such cars seems bright and in years to come, almost everyone will use solar cars because of their benefits. There are certainly some disadvantages but as the concept grows, better ideas will plunge in to remove the disadvantages. Not only will it help to reduce dependence on fossil fuels in the present but also provide resources to our coming generations.
