Time has shown us that solar powered products are proven in the field for use in our space satellites and space stations where dependable power is absolutely required in critical situations. They are also excellent products for use here on Earth. Many, many of the products we already know and use are currently available in solar powered versions. These products include battery chargers, cellular telephones, computers, fans, flashlights, fountains, garden lights, generators, gifts, hats, lanterns, lamps, lamp post lights, mobile displays, motion detector lights, personal computers, pumps, radios, security lights, signs, sports bottles, toys, ventilators, visors, wells, and the list goes on and on. In fact, any product that can be powered by DC voltage is a potential candidate for a solar power system and there are a host of manufacturers producing high quality products solar ready.
Solar energy is nearly free energy.
Think about it, solar light energy rains upon the surface of the Earth from the Sun every day of the year. Utility companies must dislike this deceptively simple and natural system because the even the basic component used in solar power is made from the most simple of all materials - sand. The photovoltaic solar power cell is made from silica sand and is doped with other materials in a manufacturing process. This right combination of materials is actually sensitive to intense light energy. The Sun, and intense incandescent lights can also excite a solar cell.
