Can Solar Energy Benefit You?
Solar energy does not produce any environment harming pollutants.
Currently there are two methods of harnessing solar energy; thermal conversion and photovoltaic conversion. Solar thermal conversion is a method that uses sunlight to create heat and then converts it to electrical power. 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) This method utilizes reflecting surfaces and mirrors to amplify the amount of heat that can be generated. (Thermal energy is a type of energy). If you have ever starting a magnifying glass fire, than you were using solar energy. To create a pinpoint of intense heat magnifying glass lenses are used. When using actual solar cells they use this method to produce steam by superheating liquids. The steam that is produced will turn a turbine and produce electricity.
Photovoltaic Conversion translates to light that is converted to electricity. Photovoltaic cells usually consist of panels, which contain two layers of different materials. This is accomplished when sunlight comes into contact with the two surfaces, causing each to attain an opposite charge. 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 sunlight it creates electricity.
A solar power cell’s speed of generating electricity is relative to the brightness of the sun: the brighter the faster. 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 has so many advantages including, portability when traveling or camping, and it is environmentally friendly.
As written earlier, anybody whom has used a handheld or lighted magnifying glass to get a fire going, has already put solar energy to work for them.
The tools currently on the market save more power and produce better results than previous models. The use of solar power is very promising for our use now and into the future.
