A Bright Future for Solar Energy-an Alternative Energy Source

I used to be introduced to solar energy within the movie, Race the Sun with James Belushi and Halley Berry in the lead 1e. It was definitely a story about low-income and reach under to the Hawaiian students encouraged by their teacher Solar Car race. In the film, a car like a cockroach shaped and lined with solar panels used rays of the Sun as an alternative energy supply the car run.

Solar panels are created by a combination of silicon with alternative elements that positive or negative cost. Solar panels are not light weight and the roof must be strong enough to demand that their weight, especially if the Panel is placed on top of existing tiles.

Solar panels are arrays of photovoltaic cells that represent an environmentally safe and clean method to take advantage of the Sun's energy and use it as a source of energy. Solar panels are composed of several individual solar cells which are themselves composed of layers of silicon, phosphorus and boron (which the negative charge), (which the positive charge).

Solar panels are widely used in rural areas that are not maintained by the utility grid. Solar panels are wired together in a PV array, and the electricity they produce is powered by an inverter that the direct current (DC) to alternating current (AC) changes, making it suitable for homes and businesses, and are compatible with the electricity grid.

Photovoltaic cells that are used to convert the light into electricity used silicon and even some waste producing. There are also large solar thermal farms and moreover these farms could be harmful to the atmosphere and desert ecosystems if not well managed.

Solar energy can be used on different aspects. Solar energy will be used in agriculture. Serres (which completely differs from greenhouse gas) converting solar light-weight to heat to be maximized in improving the growth of plants and crops. Serres is around since Roman times and modern greenhouses were built in Europe in the sixteenth century. Serres today are still an important part of horticulture

Daylight systems are also used to maximize the energy released by the Sun. It is used for the production of Interior lights replaced the synthetic lighting. Daylight systems include sawtooth roofs, lightweight shelf, skylights and light tube. Daylight systems once they are properly implemented can reduce lighting-related energy consumption by 25 percent.

Solar energy can even be developed in solar thermal energy that can be used for heating of water, house heating, area cooling and heat generation method. Solar energy can even be used to distill water and salt or brackish water potable or drinkable.

The solar water disinfection, or SODIS water-filled plastic polyethylene terephthalate is exposed or PET bottles. This process takes a very long time, because the exposure time depends on the weather conditions. It requires a minimum of six hours to two days during the days with overcast conditions. Currently there are two million people in the development of ages use SODIS for his or her daily drinking water needs.

Daylight will also be converted into electricity using photovoltaics or PV. PV is primarily used to power small and medium-sized things like a calculator powered by a single solar cell. There are homes powered by solar energy. Using solar energy for water and house heating is the most general application of solar energy use. Whereas solar air heating and ventilation also grows in popularity.

There are 3 ways in which the use of solar energy. Most way of use and change of solar energy is using the solar cells. Solar cells convert light-weight directly in electricity. Solar cells are also referred to as photovoltaic or photo-electric cells.

Meanwhile, solar furnaces use a huge range of mirrors to focus on energy from the Sun in a very small area and terribly high temperatures. Solar ovens are also known as "solar cookers". A solar cooker will be used in hot countries to cook food.

With all the benefits like using solar energy, there is still a drawback for this alternative energy source. It does not work during the night. The value of setting up solar stations is expensive, but the advantage of using solar energy is accumulated when more so far.
