Can Solar Energy Benefit You And Your Lifestyle?
November 13th, 2009
Solar energy is a clean form of energy production, which does not pollute the environment. The promise of cleaner energy and advancements in green technology has allowed solar energy research and production to take a front seat in modern energy production.
Currently there are two methods of harnessing solar energy; thermal conversion and photovoltaic conversion. Another way to generate electric power is using sunlight to create heat. This method is known as solar thermal conversion. Photovoltaic conversion uses sheets of a specialized material that can create electricity directly from the sun.
As you would expect, sunlight is required to use solar thermal conversion to generate electricity. Solar energy is a type of energy This method utilizes reflecting surfaces and mirrors to amplify the amount of heat that can be generated. (thermal). If you have ever starting a magnifying glass fire, than you were using solar energy. You are able to create a very small space of very intense heat using a magnifying glass. Actual solar cells used to store heat use this method to superheat liquids that produce steam. Steam is created, which in turn moves a turbine that converts the energy into electricity.
Photovoltaic Conversion essentially means light that is converted to electricity. Photovoltaic cells usually consist of panels, which contain two layers of different materials. One layer becomes positively charged and the other negatively when light hits them. Very much like a regular battery, which has a positive end and a negative end, when a wire connects the two ends, they produce an electric current. When you expose the two layers inside a solar panel to direct sunlight, electricity is created.
Just one solar cell will of course work better when the sun is shining. You can derive the maximum benefits by their exposure for a longer duration to direct and scorching sun.
Solar cells are used today to power anything from small personal devices, such as cell phones, to large communities. Solar power offers many benefits including the fact that it can be portable, and that it protects the earth.
As written earlier, if you have ever used a hand held or lighted magnifying glass to light a fire|to spark a flame, you have used solar energy.
The tools currently on the market save more power and produce better results than previous models. Solar power has a bright present and a promising future.
