The facts of solar energy

Most power plants in the United States and around the world use fossil fuels to produce electricity and exploitation. Have been used as an energy source while the man has learned to produce energy. These traditional energy sources have existed for centuries and where people began to use energy sources such person if the consequences. Fossil fuels will eventually run out and there will be a shortage of it in the near future. This shortages will impact on our industry alive and varied. Today, we see some of these keys and the prices of electricity and the consciousness is becoming more expensive. Although these fuels are more alert, the need is still there and will not diminish in the near future. To address this shortage, we must consider other possibilities for our energy demand.

Fortunately, alternative energy sources are becoming more interested. For example, places experiencing high water falls in the construction of a dam that is a success. Other places with high wind speed to use some wind power plants can convert the wind energy into electricity. Also, the thermal energy and tidal energy are good choices.

Solar energy is also one of energy sources is gaining interest. This form of energy has been steadily increasing. It is now widely used in the United States and elsewhere and benefits are numerous. Our solar energy source, the sun, your life is estimated at another 4.5 million years. It is fair to say that this energy source is almost endless.

Sol Energy price

Solar radiation reaches a certain unit area in space near the Earth's orbit and is estimated at 1,400 watts per square meter. In this, photovoltaic cells (also known as solar cells) can capture 19-56 watts per square meter (Efficiency 15%) or the equivalent of 0.45 to 1.35 kilowatt hours (kWh) in an annual day and midnight.

Therefore, if a larger area to be covered by several solar panels, these panels can produce a little more energy in the form of electricity that is currently available from oil, gas and other sources total energy (assuming that 8% efficient solar cells).

The solar energy conversion

There are two ways of converting energy solar. The first direct solar energy, which makes a conversion into a usable form. For example:

* The light from the sun reaches the solar cell conversion into electricity. * Sunlight hits the surface of the absorber of a solar thermal energy conversion heat can be used to heat homes during the season cold.

The second is the indirect solar energy is more than one conversion in a useable form. For example:

* Use plants in photosynthesis to convert solar energy into chemical energy that can be burned later as fuel to generate electricity (also known as bio-fuel technology).

* The hydroelectric and wind turbines are indirectly supplied by solar energy through its interaction with the air.

Solar Energy Advantages and Disadvantages

Like any other energy resources, this energy source has its advantages and disadvantages.

Advantage

* No pollution. * Solar installations can be performed with little maintenance. * There is abundant. As mentioned above, most populated areas on Earth can be reached by sunlight.

Disadvantages:

* While there is abundant, some areas receive little sunshine. Thus, the power to be produced in these places is a minimum. * Only available during the day, therefore a need to store energy for use in night. * Photovoltaic cells generate direct current technologies (CC), which is converted into alternating current (AC) used in distribution networks.

Once the massive development of solar energy use materializes, it is expected that each household or industry in the world now will be powered by energy Dom This is not just a dream, a dream will come true.
