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. Since the sun is an abundant energy source, 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 world^a?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. Unless you have a background in chemistry, you cannot understand fully the working of solar panels. However, each panel is a collecton of photovoltaic, in layman's terms. (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. Solar power is generated with no moving parts; therefore, the panels require no maintenance. Each of the 14 types of PV cells is made of some kind of silicon. It is now most common to 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.
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. we can take advantage of all the power the sun has to offer.
