SOLAR POWER IN CARS

September 10, 2011

solar-auto-carsSolar energy is one of the many renewable sources of energy that is used for fueling vehicles, running consumer products and for the efficient running of homes and business establishments. Solar power is harnessed with the help of solar cells and solar panels which are placed in the item that has to be powered.

The solar car is something that is envisioned to materialize in the future, with some countries already having solar cars racing across countries.
With this, it is proven that it is viable to indeed produce and manufacture solar power cars in bulk, in the near future so that everyone will soon own a solar power car.

Of course, once solar power cars are manufactured, it does not implicate that all other fuel sources for cars on highways will be removed. All that is done in solar power cars is the supplementation of traditional fuel with solar energy so that you save not only on your economy, but also save the environment in more ways than one every year.

The solar power cars that are used in races today run only on solar power, and thus look odd in appearance. This is because these cars are designed in such a way that they can collect maximum solar energy with which it is possible for the car to gain the required speed and desired efficiency.

The solar cells used in solar power cars are large, and usually cover the entire vehicle. However in case of commercial uses, solar cells are much smaller and designed so that the vehicle not only looks attractive, but is also efficient in its functioning. Solar cars can be used for short commutes in town as these cars can work only on solar energy.

The batteries found in the vehicle stores excess solar power so that this power can be used when solar power is not available on demand like on cloudy days and at nighttime. The engines found in these solar power cars are very much like the engines found in electric cars found today. In addition to this, the cars are lightweight, so that solar power can be used more efficiently.

At present, there are many types of solar power cars in the development stage today, which are also available for sale. However as these cars are in the developmental stage, the car is not available to the general public. With so many benefits found in solar power cars, its cost will not be much higher than the cost of the traditionally powered vehicles of today.

Another benefit of solar power cars is there is no hassle of stopping at gas stations for gas nor is there the need of getting worried of rising gasoline costs. With a solar power car, you save on the money that you would have otherwise have needed for buying fuel to run your car. In addition to this, with solar power cars you will be doing your bit in stopping global warming problems as there are no fuel emissions from solar power cars.

WIRING A HOME FOR SOLAR ELECTRIC POWER

September 10, 2011

wiring-homeSolar energy is one of the more sought after sources of energy in the market today.

With solar energy, air pollution is reduced as there are no fumes that are emitted while working with solar energy. Moreover, solar energy is available for free; where you only have to pay for the solar energy system, its installation and wiring.

The wiring of a home that is to run on solar electric power has to be done by a skilled person, and with care to ensure that electric devices and appliances in the solar powered home are used safely.

However if you intend to plan or design a solar home, it is better to do so after understanding the process of getting solar power from the solar cells and panels to the outlets and appliances found in your house.

Though homes with solar power and homes with fossil fuel generated power sources use 120 volt alternating current, there are differences in the wiring and additional equipment that is usually used in the expensive electric power grid.

Though you will have to pay some initial expenditure for installing your solar energy power system, this investment pays for itself over a period of years where you in fact, end up saving money you would have spent paying for the costs of increasing traditional power rates.

It is important to insulate your home well when planning a solar home. Buy windows that are not only well sealed, but also double paned. They have to be installed so that there is no seepage of drafts around the window frames and door jams. You also have to be specific about attic and ceiling insulation as the less the amount of heat and cool air that is lost to the outside, the les is the energy required to replace comfort controlled air. With this, there is less demand made on your solar electric power system.

Your solar power generator needs a battery meter and a start-stop switch. You need more electric outlets here than in a non-solar home so that task areas are lighted and not entire rooms. Place a few low voltage outlets to save money in devices using little energy like telephone answering machine, fan and others.

Don’t forget to place a few electric outlets outside so that the solar electric power system can be used for powering tools and for any outside activities. Remember that you get lots of extra free power in summer where you can think of using an electric lawn mower or fountain pump. You could also consider providing lighting for a shed or garage for power tools and emergency battery charger to start your car with.

You could also install special 12 volt DC motion sensor lights at the entrance of your home so that it lights up even if the inverter is in idle mode. Remember that solar powered homed don’t allow for 220 volt AC appliances operating from 240 volt AC section of wiring.

If you need such appliances, you will have to depend on traditional power to use them. However it is better to buy appliances using 120 volt models as most equipment are available this way. With this, you will be able to use all your equipment with solar power in your solar power home and thus save lots of money in the fuel costs of your home.
