In the 1800s, solar energy was first used. As a source of power for the home, solar energy hasn't proliferated as it has with calculators and wristwatches. Solar power got off to a rough start in the previous century.S. experienced oil crises or embargos. But its proliferation has not yet been accomplished, mainly due to its cost.
Here in the 21st century, renewable energy has once again become a hot topic. Steps are needed to save our planet, including using fewer fossil fuels. We need only to harness a portion of its solar power to meet our present energy demands.
In fact, if just 4 percent of the earth's entire desert area contained solar panels, it would supply all of the electricity the world needs.
We can harness the power of the sun with the use of solar panels. To fully comprehend how solar panels work requires a background in chemistry. However, each panel is a collecton of photovoltaic, in layman's terms. (PV) cells. The inner content of each PV cell is highly-purified silicon. Silicon has properties that act as both a metal and an insulator.
The light from the sun is captured by the PV cells, and creates solar power by producing electricity. When sunlight hits the panel, electrons are dislodged. This creates an electrical current that can be used or stored. Storing excess power is a problem with solar energy because the sun does not shine all the time and PV cells do not store power. The solution is deep cycle rechargable batteries, which can store power harnessed from the sun.
Solar panels work quietly and do not produce radiation. Since the parts don't move while generating solar power the panels rarely brake down. Presently there are 14 types of PV cells, each made of varying kinds of silicon. use solar panels as a supplemental energy source for utility customers, rather than as their sole energy source.
Your building's roof or its windows can have solar panels built right in. Facades and canopies are also suitable applications.
New kinds of solar panels are now being researched. The objective is to increase efficiency and lower costs associated with using solar energy. we can take advantage of all the power the sun has to offer.
