Solar Cells: The Route To Freedom From Foreign Oil
In Greek mythology sun deities were was known as Helios and Apollo. The sun-god Ra, was the first king of Egypt. In different manners, the sun has been worshiped throughout history and has also played a major role in some religions. The suns influence has been seen in Buddhism, Hinduism, and many of the native American tribes, to name a few. Solar energy has influenced mankind for centuries
The appearance of the sun in the sky is prominent due to the fact that it is the closet star to the our planet. The sun not only emits light, but also heat that is transformed into various forms of energy. The simple act of laundry being hung out of doors, uses the suns heat as a form of energy to dry our clothing. The suns light also enables plants to produce food. The uneaten foods would then decay and in a process that took millions of years fossil fuels such as coal, natural gas, and oil were produced. Exploding stars referred to as nova’s produce nuclear energy through the emission of uranium atoms.
The uses for the suns energy are infinite. Humankind has long made use of its properties. The 1890′s found people heating their hot water with solar energy. Cheaper than wood and coal, it was also a cleaner alternative. In the U. S. The states having the sunniest and warmest number of days emerged as the first ones to use solar energy for heating water. Solar panels to heat water were installed in thousands of homes by the 1920′s. When greater amounts of oil and gas were found and prices plummeted for these fuels, many reverted back to their use. Presently, there is concern that the demand is beginning to exceed the supply and solar energy has moved again to the forefront.
Electricity is another horizon being developed with the use of solar energy. Located in California’s Mojave Desert, one can find row upon row of solar mirrors. These mirrors are called parabolic troughs as they collect sunlight in a specific way. The suns heat becomes so intense that it can boil water and the resulting steam in turn will power a turbine to produce electricity. Other forms of power plants, some still in the experimental stage, are focusing their efforts toward greater efficiency in the production of electricity.
Sunlight can now be changed directly into electricity by the use of PV’s or photovoltaic cells. Modules of these cells now have tracking devices and can collect sunlight continuously. Once the sun hits a solar cell, electrons become loose and travel to a front surface. This in turn will create an imbalance of the surfaces which perform as a connector allowing the electricity to form a current between the sides of the positive and negative.
The immediate availability of use when implementing this direct energy form is an invaluable source of power. It can light city’s as well as individual homes. Illuminated billboards and streetlights; roadside phones; appliances and home heating are all made possible.
There is still much to be discovered with the ongoing research of solar technologists. One of the latest frontiers is the electric powered automobile. The capability of PV cells in turning the suns energy directly into electricity will enable the motor s use of the electricity to keep it running smoothly, efficiently, and cleanly. The pollution created by older methods of power will disappear with the use of the suns energy. Technology that at one time was located miles above the Earth is now literally at our fingertips.
Wind Energy Windy conditions are ideal for placement of wind turbines. Windy conditions are ideal for placement of wind turbines. The more wind there is, the more electricity can be made.
Can You Convert Your Home Into A Solar Home?
When it comes to converting your home into a solar home, there are a few alternatives, because not all homes have the same problems, the same requirements or the same potential sustainable power sources. Therefore, if you are going to try a total conversion or even get off the grid completely, you will either have to do some do research or call in an expert to make a report for you.
If you call in an expert, try to get an independent one, so that you can work out the costs of satisfying your energy requirements yourself. You will have to pay for such a survey, naturally, but you could carry out a report yourself with a bit of work on your part. In order to create a solar home, you may find the rest of this piece interesting.
There are fundamentally two types of solar design: passive and active solar energy. Passive solar energy can be used to supply heating, cooling and natural light for your home. Active solar energy is employed for powering home appliances, tools and lighting. It is the ideal blend of these two types of solar energy that you will try to achieve, if you are attempting to convert your home into a solar home.
You can use passive solar energy techniques in many ways, although they are more easily incorporated in during the actual construction phase of a new home. The largest area of glass should face south or be within 30 degrees of due south. This will collect the maximum amount of heat. This heat can then be distributed around the house by stone floors and stone walls.
The central heating ducting and furnace fan can be used to assist, if need be. If the house becomes too hot in the summer, awnings or even solar panels could be dropped down in order to put the windows in shadow. When thinking of passive solar energy, you should try to think of ways of providing warmth and coolness without using electricity. For example, a skylight at the top of the stairs will allow the warmest air in the house to escape, since hot air rises. This will cause cooler air to be sucked into the house at lower levels.
The other aspect of a solar house is the generation of electricity by the deployment of solar panels grouped into solar arrays. Solar panels make use of photovoltaic cells to convert light into energy. This energy can then be used to power ordinary electrical appliances of all kinds or some or all of it can be stored in batteries for later use. Conversion from AC (alternating current) to DC (direct current) and back again, if needed, is a straightforward matter.
Solar energy can also be used to heat water for the pool or for the home. The most usual type of system uses pipes filled with a type of anti-freeze to collect the sun’s heat and pass it on to tanks of water by means of a heat exchanger.
A solar home uses energy efficiency to minimize the necessity for heating, cooling and electricity. The use of higher grade lagging, more energy efficient windows, kitchen appliances and lighting than those utilized in traditional homes, will save you a lot of money and energy. As you can see, some of these changes, particularly the passive ones are structural, so hard to apply in many homes, but there is always something you can do to reduce your energy bills and gradually convert your home into a solar home.

Home solar panel products are occasionally fitted on top of roofs, erasing the headache of establishing the whereabouts of a suitable place for installment. Solar systems will need little or zero servicing, one of many big solar energy advantages.
Satellites revolving about our world in space, which aren’t even looked after, use the original PV cells know-how. A number of solar electric panel manufacturers give twenty five years warranty on their particular products.
Simply because most areas of the nation get plenty of sun light for the duration of the year, Photovoltaic systems may be installed anyplace. Numerous state governments in America provide tax credits and discounts to homeowners who wish to utilize a home solar panel systems. Check with your own individual individual state regarding the rate associated with these credits.
There’s yet another beneficial, and frequently overlooked solar energy advantages, coming from creating electrical power from photovoltaic panels. For electrical power companies to distribute electricity to all homes, they require products needed in building these kinds of factories, along with power lines made from electric cable and steel.
These require energy to produce, and bring about greenhouse gas air pollution levels. In situations where we can cut the requirement for electrical power plants and switch to renewable energy, we will likely in addition decrease the requirement for numerous segments and help environmental surroundings.
The rewards of using environmentally friendly energy sources, including solar and wind energy, is that it’s clean and won’t have a damaging effect on the ecosystem. It’s also renewable, which means we will never exhaust it. Should the oil fields be used up, the industry possibility, individuals and nations that have not turned to a environmentally friendly alternative power source, will discover themselves in a troublesome way.
We must all look at these solar energy facts, and consider investing in purchasing or producing our very own photovoltaic panels as an electric power source.
