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.
In 1839 Alexandre Edmond Becquerel discovered the photovoltaic effect which explains how electricity can be generated from sunlight. He claimed that “shining a light on an electrode submerged in a conductive solution would create an electric current.†However, even after much research and development subsequent to the discovery, photovoltaic power continued to be very inefficient and solar cells were used mainly for the purposes of measuring light.
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.
