- 2. C.G.P.I.T Summary A solar car is a solar vehicle used for land transport. Solar cars combine technology typically used in the aerospace, bicycle , alternative energy and automotive industries. The design of a solar vehicle is severely limited by the amount of energy input into the car. Solar cars depend on photovoltaic cells to convert sunlight into electricity. Unlike solar thermal energy which converts solar energy to heat for either household purposes, industrial purposes or to be converted to electricity.
- 3. C.G.P.I.T Intro In today's climate of growing energy needs and increasing environmental concern, alternatives to the use of non-renewable and polluting fossil fuels have to be investigated. One such alternative is solar energy. Solar energy is quite simply the energy produced directly by the sun and collected elsewhere, normally the Earth. Only a very small fraction of the total radiation produced reaches the Earth. Much of the world's required energy can be supplied directly by solar power. Methods of collecting and storing solar energy vary depending on the uses planned for the solar generator. In general, there are three types of collectors and many forms of storage units. The three types of collectors are flat-plate collectors, focusing collectors, and passive collectors. We are using hear flat-plate collector which are commonly known as solar array.
- 4. C.G.P.I.T Background of solar energy The history of photovoltaic energy (solar cells) started way back in 1876. William Grylls Adams along with a student of his, Richard Day, discovered that when selenium was exposed to light, it produced electricity. An electricity expert, Werner von Siemens, stated that the discovery was "scientifically of the most far-reaching importance". The selenium cells were not efficient, but it was proved that light, without heat or moving parts, could be converted into electricity. In 1953, Calvin Fuller, Gerald Pearson, and Daryl Chapin, discovered the silicon solar cell. This cell actually produced enough electricity and was efficient enough to run small electrical devices. The New York Times stated that this discovery was "the beginning of a new era, leading eventually to the realization of harnessing the almost limitless energy of the sun for the uses of civilization."

- 8. C.G.P.I.T Design Explanation At first we made a normal car. After that we attach a gear in the motor and in the tyres too. After that we connect a solar array to the motor. Solar array catch the sun light & transfer it into electricity which runs the motor as well as the car. If you want to save energy you can attach rechargeable battery to the solar array and then after connect motor to the battery.

- 11. C.G.P.I.T How it Works. Solar cars are powered by the sun's energy. The main component of a solar car is its solar array, which collect the energy from the sun and converts it into usable electrical energy. The solar cells collect a portion of the sun's energy and stores it into the batteries of the solar car. Before that happens, power trackers converts the energy collected from the solar array to the proper system voltage, so that the batteries and the motor can use it. After the energy is stored in the batteries, it is available for use by the motor & motor controller to drive the car. The motor controller adjusts the amount of energy that flows to the motor to correspond to the throttle. The motor uses that energy to drive the wheels.
- 12. C.G.P.I.T Conclusion Solar energy and more specifically solar cars would be an amazing advancement in future car technology. They would allow for free travel and nearly unlimited accessibility. But solar cars are not suceessful at all places like Antarctica which see the sun rarely. If the hurdles can be passed then for sure solar cars will be the wave of the future.
