Solar energy does not pollute the environment because it is a clean form of energy.
At the present time, photovoltaic and thermal conversion are the only two ways to harnessing solar energy. 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, has proved by science that its power is effective not costly. It uses properties of reflection to create intense heat. (Thermal energy is a type of energy). The method used to start fires with a magnifying glass is called solar thermal conversion. The magnifying glass lens concentrates the suns rays to create a pinpoint of intense heat. 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 electrity.
Electricity is generated using Photovoltaic Conversion, which transforms sunlight into electricity. Photovoltaic cells usually consist of panels, which contain two layers of different materials. When light hits these two layers, one becomes positively charged while the other becomes negatively charged. When a wire connects the two ends of a battery it produces an electric current. When the two layers of material in a solar cell are exposed to light, an electric current is created.
Just one solar cell will of course work better when the sun is shining. The longer, more intense and most direct sunlight will produce the best results.
These days you can find many different products that are solar powered. Solar power has the advantage of portability while traveling or camping, not to mention it also very environmentally friendly. As mentioned earlier, if you have ever used a handheld magnifying glass to start a campfire, you have used solar energy. The devices offered today are more efficient and effective then ever before. Solar power has a bright present and a promising future.
