With the recent rise in energy costs, many people have been looking for alternative sources of energy. One of the greatest energy sources (our sun) is readily available for the taking. We just need to be able to harness its power.
Photovoltaics are devices that use what is known as the photovoltaic effect to generate electricity from sunlight. Knowledge around this phenomenon has only been around for about two centuries, which is why the history of solar cells (photovoltaics) begins in the middle of the article.
Historians claim that Archimedes, a Greek inventor, put solar energy to use already in the 3rd Century BC. He destroyed enemy ships with fire during the Siege of Syracuse with a “heat rayâ€, which supposedly was a collection of mirrors that concentrated sunlight onto the ships. Whether or not Archimedes’ invention has any root, in reality, is uncertain. Several experiments have been carried out to verify or bust the story, most of which concluded in the phenomena being possible, but highly unlikely.
Recently new technology has given us solar powered lightings. These lightings have proved to be the best solutions for flagpole lightings. Solar panel manufacturers are now playing a key role in the solar power industry.
The U.S. Code states that: "It is the universal custom to display the flag only from sunrise to sunset on buildings and on stationary flagstaffs in the open. However, when a patriotic effect is desired, the flag may be displayed twenty-four hours a day if properly illuminated during the hours of darkness." Flagpole Lighting is ideal for lighting up flag poles so there is no longer the need to lower your flag at dusk anymore. You can install the light and panel at the bottom of the flag pole.
There is a barrage of cheap solar powered flagpole lightings being imported and sold, that do not comply with the flag statute. This is bad for a number of reasons. Imported stuff is cheaply made and more importantly, the designs, materials, colors, and methods do not compare well with the better quality, longer-lasting, and correctly designed flagpole lightings made by American manufacturers. The Flag Company Inc specialized in flags and flagpole lightings offered a special edition of solar powered flagpole lightings to provide innovative solutions for individual projects.
