The massive potential of solar energy is almost too hard to grasp, which is why harnessing this Sun’s energy for useful purposes has sparked the interest of many scientists for thousands of years. This article consists of a timeline of milestone historic events around human’s efforts to extract solar energy.
The history of photovoltaic energy (aka. solar cells) started way back in 1876. William Grylls Adams along with a student of his, Richard Day, discovered that when selenium was exposed to light, it produced electricity. An electricity expert, Werner von Siemens, stated that the discovery was "scientifically of the most far-reaching importance". The selenium cells were not efficient, but it was proved that light, without heat or moving parts, could be converted into electricity.
Solar power is a rapidly developing energy source in Australia and around the world. The potential for using the sun to directly supply our power needs is huge. Solar panels can generate electricity without any waste or pollution, or dependence on the Earths natural resources once they are constructed. They have no moving parts so modules are very reliable and have a long lifespan. Solar panels are relatively easy to install and are very low maintenance.
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.
