Because of global warming and other environmental issues, tragedies, natural calamities and terrible events are very rampant and are happening in almost any part of the world. This has resulted into other major concerns like food scarcity and increasing price of goods and services. Every person’s need for practicality has surfaced in the effort to lessen the daily expenses. For a more practical and environment friendly option, people even opted to use alternative energy resources. To those who are well informed of its benefits still prefer this. Examples of these resources are solar energy, biomass energy, wind energy, hydrogen, hydropower energy, and geothermal energy. Solar energy technologies that are used today have begun almost 40 or 50 years ago. The energy emanated from the sun is absorbed by solar electric panels and then converts it into electricity using Photovoltaic cells or PV cells. Solar energy is the most commonly used among the alternative energy resources available because of its practical use and renew ability.
These can be classified into four different types. Polycrystalline SE Panel is the most common type; it is composed of chunks of silicon that has many tiny crystals. Although this is less efficient when compared to single crystal, the watts per square foot power it releases may match the single type if they are assembled closely together in a frame. Amorphous Solar Electric Panel is identified as ‘thin film’, since it uses large plates similar to stainless steels where the silicon is stretched out to gather solar power. Vaporware Solar Electric Panel is said to lessen power expenses. Some claimed this to be the future of solar energy (no major production yet) and it works by spraying plastic over the solar cells. Monocrystalline SE Panel is also called ‘single crystal’, as this is taken from a large brick of crystal. This is a better choice in terms of its efficiency, but is considered the most costly type. In choosing the type of solar electric panels that you need, you must consider where it will be placed, the amount of space you got and the amount of power you need. No matter what type it may be, they have the same purpose, and that is to convert solar power into electricity.
Today’s technology is more directed into optimizing the use of solar electric panel to maximize the benefits of using solar energy. Nowadays, it is used for heating and cooling water and air, and provides electricity for home and business use. Some inventions that use solar energy include calculator, cars, chargers, flashlights and many others. It is believed and expected to provide more uses and become a major breakthrough in the future.
