Solar cells, also called photovoltaic (PV) cells by scientists, convert sunlight directly into electricity. PV gets its name from the process of converting light (photons) to electricity (voltage), which is called the PV effect. The PV effect was discovered in 1954 when scientists at Bell Telephone discovered that silicon (an element found in sand) created an electric charge when exposed to sunlight.
Solar collectors, in particular, flat panel solar collectors, are well-known devices which are used to absorb and transfer solar energy into a collection fluid. Principally, solar collectors consist of a blackened absorbing cylinder or plate contained in a housing which is frontally closed by a transparent window panel.
Another important feature of these solar collectors is they capture both direct and diffuse sunlight. It is generally assumed that flat collectors are only suitable for low-temperature applications.
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.
