Solar power is not a new concept by any means. It has been used for many years in such things as calculators and even by swimming pools for heating the water. But the use of solar power for automobiles is still a relatively new method of study. Solar power is a natural means of energy that is given off everyday. If it could somehow be utilized in the proper way, it may prove to be an efficient source of power. The race to discover the best fuel alternative is on as science continues to seek a better way.

Solar power is really nothing more than the energy that is given off by the sun. The key is finding the right means of trapping it and making it useful for other purposes. Solar powered grids are often used to attract the sunlight and absorb the sun's energy. It can then be transmitted to the object that needs to be powered.

It may come as a surprise to some consumers to learn that science has been studying solar powered vehicle options for years already. Many solar powered cars are very small and not ideal for today's market. But with increasing amounts of study this possibility might become a reality sooner than we think. Scientists have even been racing their solar powered creations in order to see how they hold up.

Solar powered options have been considered for today's current vehicles. Mazda once created a sunroof that was solar powered. It was designed to keep the inside of the car warm when it was not running and the temperature outside grew cold. These innovations are just a hint of what might be right around the corner.

One of the most obvious concerns regarding a solar powered car is what one would do if the clouds cover the sun. Normally, that would result in the loss of power and the car would come to a stop. And that certainly is not realistic in rush hour morning traffic. To fix this problem, a backup battery is included to automatically take over when the sun is absent.

For using a solar powered car, the energy from the sun would have to be diverted to both the backup battery as well as running the car. Otherwise, there wouldn't be enough energy to cover both facets. This could be seen as a serious disadvantage of a solar powered car.

Another drawback of using solar power as a fuel alternative is that it has to be converted after it comes from the sun. It just cannot be done direct. This might include added costs just to obtain the energy needed to power both the car and backup battery.

The solar cars that are currently in use by science for study are nothing like today's cars. You cannot get in them and they are very low to the ground. It is virtually improbable to see this get on the market. However, if the idea behind this model could be upgraded to fit the cars of today, it may be a worthy possibility.

Environmental concerns are leading to new trends in the automotive market. Some of these changing trends are currently under study and being put into practice. Solar powered cars are not new ideas but the changing technology and evolution of the idea is. Solar power can be used for energy in many things and cars is just another of them. Though many people feel that solar power is a great solution for the current fossil fuel problems, there are disadvantages to using it. Like with any energy source, it will have both positive and negative points.

Currently, it is not all that simple for science to discover a way to effectively draw and use solar energy. Solar panels are often required, similar to the ones found on a calculator. However, it is not really all that realistic to line the outside of your car with solar panels. It is not efficient and most drivers would laugh at the idea. Switching away from fossil fuels should be easier than that if it is to appeal to drivers in mass amounts. If it is difficult then people will not be likely to make the switch.

Solar cars would also need to be fully equipped with special gauges that measure the amount of energy, how much is being consumed by the car and how much is remaining. Drivers would have to be able to understand these gauges and utilize them. It could be possible to have a solar powered car that does not have many gauges but that would require an entirely different set up. The solar cars that are currently in production have only three wheels which is not something that is going to be acceptable on the current cars of today.

Science is currently testing many types of solar powered cars by racing them. This is a great way to test the limits and functionality of using solar power. Solar powered bicycles are already being produced and used. Perhaps this is a better place to start since cars do not seem ready to become solar powered machines. Though it is a great idea, it is not yet ready for the North American public. Solar cars that are currently in production are very small and can usually only hold one person, which is the driver. This type of car would not be approved in the United States based on the current safety standards required.

It is quite obvious that one negative aspect of solar energy is being able to use it when the sun is not shining or during an overcast day. Many improvements need to be made for this to be a viable alternative to fossil fuels. Having solar cells on the vehicle will not be all that convenient for drivers either. Having a solar powered vehicle would be a great option if it was ready to be released in mass quantities. However, at this stage in the development it just is not a conceivable idea. Solar energy is a fantastic natural resource. With further study, hopefully it can soon be a realistic petroleum alternative.

Years ago, no one ever thought that solar powered vehicles are even possible. There are solar-powered calculators or solar batteries that can run small devices but as for solar-powered car engines, many have remained skeptical until they finally saw actual vehicles that run on the energy of the sun created for exhibits in various science and technology fairs. These days, many are already considering on the possibility that, in the next couple of years, mass-market solar powered vehicles will be available to consumers in replacement for the ones that run on oil fuel.

These days, one can see solar powered vehicles in engineering demonstrations and solar car race events.

Cost-efficient

Solar-powered vehicles are, without a doubt, more cost-efficient than the typical cars that run on oil fuel. After all, these cars harness energy from something that is abundant ' the energy from the sun. So long as the sun shines, these cars should be able to run just as efficiently as any other type of vehicle. Because they run on solar power, these vehicles will also enjoy higher mileage and longer life spans according to most experts. Solar powered vehicles offer a lot of benefits to the potential consumers who would be willing to invest on such cars.

While solar powered vehicles are not yet practical day-to-day transportation devices, it's only a matter of time before they actually get introduced into the market.

How they work

Solar powered vehicles literally run on the energy coming from the sun. They follow the same idea as that of other solar-powered devices such as calculators or batteries. The surface of the car has solar panels that collect solar energy. Photovoltaic cells installed in the vehicle work to convert this energy into electrical energy that the engine will need to run the car. In theory, solar powered vehicles will only run when the sun is present. However, numerous studies are now being conducted with regards to the creation of energy trapping components that will enable the car to store enough energy for it to run even at night.

Design

The design of solar powered vehicles is largely limited by solar batteries that are installed in it. Most cars that run on the sun's energy are designed to be lightweight. Every component shouldn't weigh as much as the ones that you would typically find in conventional cars. They do have practically the same basic parts that traditional vehicles have. You will find brakes and accelerators in them. Some even come with cruise control.

Challenges

With solar powered vehicles, the current challenge is to create a process or a mechanism that is capable of harnessing solar energy efficiently even on places with a relatively smaller surface area such as cars roofs. Solar cells are usually effective on buildings because they are always exposed to the sun's heat. Cars will warrant more attention on this area to create efficient solar powered vehicles that can be used just like cars that run on oil fuel.
