General information on solar energy

Solar energy is renewable, clean energy already thousands of years, in one way or another. The following is an overview of the solar energy.

General information about solar energy

Solar energy it all comes down to using solar energy to produce energy.Sun rain enough solar energy on Earth in power, all energy needs in the world for one year Solar energy is considered to be a source of renewable energy, as it will exist as long as our Sun, it is estimated that another 4.5 billion years. Solar energy is also considered to be environmentally friendly energy because it does not produce any contaminants and by-products that are harmful to the environment.

Solar energy was the first source energy used by mankind. use limited to drying and heating caused by direct contact, but it was using. In modern times solar energy power supply since the early 1950s, but is not widely used because of technological problems, which made the source energy inefficient and expensive. With advances in solar energy moves to the fore as a potential alternative to fossil fuels.

In the future, really bright solar energy as new solar nanotechnology close to create solar platforms that Boggle the mind. For example, several companies are trying to create solar quantum dots, which are merged in the paint you use for your home. Yes, you actually will draw on panels solar energy that power your home

At present mainly through the use of solar panels, solar photovoltaic cells are energy.This process works by putting cells in direct sunlight. Sun hits cells, causing a chemical reaction that produces an electric current. Current became electricity. The problem with these cells, they are only around 15% efficiency.

Solar energy are usually classified in two ways, passive and active solar solar. Both approaches solar energy, but very different ways

Passive solar exactly what it sounds like she is not related to the systems or other moving machinery for the production of solar energy. Instead, passive solar includes planning structures in such a way as to take power Sun windowing, tanks and so on. These systems can be used to heat homes, water, etc.

Active solar energy systems typically include solar panels in one form or another.The target for maximum exposure to the Sun.Depending on the system tray will then either convert sunlight directly to electricity, which is then converted from a DC current electricity energy alternatives and stored in batteries or the grid system of local utility.Active systems are more expensive and complicated.

Solar energy has many advantages over other renewable energy.This produces no pollution, requires little maintenance, and comes with significant financial incentives in the form of tax deductions, tax exemptions and rebates from manufacturers.In most States solar energy can also be sold on the concept known as pure this reduces the need for batteries, while significantly reducing utility costs.

Unfortunately solar energy has some drawbacks, the initial cost of acquisition and installation can be expensive. second problematic areas with limited sunlight. Thirdly, solar energy clearly cannot be carried out at night. Despite these shortcomings solar energy is thriving platform energy.

The largest producers of solar energy worldwide were Germany, Japan and USA California Solar Initiative, recently is dedicated to promoting the use of solar energy residents in more than three billion dollars as shown in this review, the platform solar energy coming on strong.
