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.

Thermal conversion and photovoltaic conversion are the two methods of solar energy used today. Using the heat of the sun to make electricity is known as solar conversion. Specialized material that can directly turn sunlight into electricity is involved in photovoltaic conversion.

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.

The efficiency of a single solar cell is determined by its exposure to direct sunlight. Both time and intensity of sunlight will play a factor.

Solar cells are used to generate electricity for a variety of things, such as cell phones and entire communities. Solar power has the advantage of portability while traveling or camping, not to mention it also very environmentally friendly.

As stated earlier, anytime someone uses a handheld or lighted magnifying glass to get a fire going, have used solar energy.

The devices offered today are more efficient and effective then ever before. The use of solar power is very promising for our use now and into the future.
