Solar collectors are trying to save energy wasted in daytime electric lighting, which "represents the single largest consumer of electricity in commercial and residential buildings." Artificial lights are inefficient not just in the way they produce light from electricity (only a fraction of the electricity they take in emerges as light), but because they often squander the light they make with shades, fittings, dimmers, diffusers, and so on.
Today, people use solar energy to heat buildings and water and to generate electricity. Solar energy accounts for a very small percentage of U.S. energyâ€"less than one percent. Solar energy is mostly used by residences and to generate electricity.
A solar powered lighting system provides a lighting element assembly having a lighting element and a diffuser that secures near the upper end of a support. A collector unit contains a solar cell and a coupler such as a clip-on clamp which allows the collector unit to be selectively attached to the desired support.
The lighting system includes a battery electrically coupled to the solar cell of the collector unit and to the lighting element assembly using a wire such that the portion of the wire that extends from the collector unit to the lighting element assembly is of sufficient length to allow the collector unit to be selectively positioned on or remotely from the support.
Solar collector efficiency is influenced by several factors like heat gain, surface area, the conversion factor and heat loss through conduction and convection. Low-temperature solar collector models operate at high-efficiency levels when the temperature difference is between 5 and 30°C (41 and 86°F) and medium-temperature models operate when the temperature difference is between 15 and 200°C (59 and 392°F).
However, there is a barrage of cheap solar collectors 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 solar collectors made by American manufacturers. The Flag Company Inc specialized in flags and flagpole lightings offered a special edition of solar-powered collectors to provide innovative solutions for individual projects.
