Do you remember that first time when you asked yourself: What is the solar energy exactly? The answer is very simple, anyone can understand it. It is the energy that the sun produces in the form of heat and light. This is the most renewable and one of the most easily available source of the energy. What makes it one of the far-out sources of energy? The fact that it is free and there is plenty of it. Solar energy isn’t a brand new term. As a matter of fact, ancient people have been using quite simple magnifying glasses to concentrate the light of the sun into beams. These beams were so hot that the wood could easily catch a fire.
In modern world, solar power is either being converted into the electricity or into heat energy. Solar energy can be converted into electricity through of solar thermo energy and photovoltaic. With the help of solar photovoltaic (PV) modules, solar radiation gets converted into electricity directly. People use this energy to power solar calculators, watches, and even traffic signals. They’re usually at places where there’s no option to be connected to the electricity grid. Sun power can be used to heat water and space heating which means heating the space inside the building. While it does sound fantastic, it is pure truth.
Active and Passive Solar Energy
So, there are two types of such energy. It just depends on how it is being captured and then utilized. Active solar energy is considered to be the one when it is used special equipment to convert solar energy into heat. A person will need to use mechanical equipment such as PV modules, solar thermal collectors or pumps and fans for catching the solar energy.
As for the passive one, there is no need in any mechanical equipment. There are these passive solar technologies that trap and keep the heat. They are: walls, building placements, windows, trees and many others. Remember what usually happens to your car on a hot summer day? Well, this is a great example of how passive solar energy actually works.
Impact on Environment
The first and the most important is that solar energy doesn’t pollute our air while converting to electricity with the help of solar panels. It is, indeed, the cleanest source of energy among today’s available sources. However, it does have some impact. Silicon and some waste products are required to produce solar cells. Ill-usage of these materials may result in dangerous exposure to people and the environment in general. Be careful when choosing solar panels company. Nevertheless, solar panels at SolarPanelsCompany.com have zero impact on global warming. The more people choose to use solar energy, the better ecology we will have.
Solar Energy and the Future
Solar power has a tremendous potential. Thanks to new developments, solar energy now plays even larger role in our future. It goes without saying that an average household will always be looking for ways of reducing his monthly electricity bills. The market expects millions of new households to try out sun power as an alternative source of electrical power in the next couple of years. On top of that, everyone is very worried about global warming which is basically caused by humans producing too much of unnatural power. This will all change very soon. We are capable of making this world a better place.
