The Process By Which Solar Energy Produces Electricity

In the 1800s, solar energy was first used. Although it is common for calcators and wristwatches to operate with solar energy, its proliferation as a source of power for the home is not as common. Solar power got off to a rough start in the previous century.S. underwent periods of oil shortages and 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. Not only is it important for our nation to become less dependent on fossil fuels, we also need to take steps to help save our environment. We need only to harness a portion of its solar power to meet our present energy demands.

solar panels in just 4 percent of the worldâ??s desert area is sufficient to provide electricity for the whole universe. By utilizing solar panels, it is possible to tap into the sun's energy source. To fully comprehend how solar panels work requires a background in chemistry. In layman's terms, however, each panel is a collection of photovoltaic (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 PV cells create solar power by converting sunlight to electricity. Electrons come away from the panel when sunlight makes contact with it. 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.

PV cells perform the electric conversion silently and without pollution, and the solar panels do not emit any radiation. Since the parts don't move while generating residential 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.

Solar panels can be built right into your building's roof or its windows. You may think of facades and canopies also.

At the present time, research is being conducted to develop newer types of solar panels. The goals are increased effectiveness in harnessing solar power, as well as reducing its cost. When that time comes, we can take advantage of all the power the sun has to offer.
