ï»¿Solar energy was first used in the 1800s. 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. The use of home solar power experienced fits and starts in the last century, especially whenever the U.S. experienced oil crises or embargos. But its proliferation has not yet been accomplished, mainly due to its cost.
As we begin a new century, replenishable energy sources are a big topic once more. 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.
Solar Panels in just 4 percent of the worldâ??s desert area is sufficient to provide electricity for the whole universe.
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. In layman's terms, however, each panel is a collection of photovoltaic (PV) cells. Each PV cell is made of highly-purified silicon. Silicon acts both as an insulator as well as a metal. The light from the sun is captured by the PV cells, and creates solar power by producing electricity.
Electrons come away from the panel when sunlight makes contact with it. An electrical current is created, which can either be used immediately or stored for later use. Since the sun is intermittent, and since PV cells do not store energy, the excess power can be stored in deep-cycle rechargeable batteries.
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.
Solar panels can be built right into your building's roof or its windows. You may think of facades and canopies also.
New kinds of solar panels are now being researched. The goals are increased effectiveness in harnessing solar power, as well as reducing its cost. we can take advantage of all the power the sun has to offer.
