Every day, the sun radiates (sends out) an enormous amount of energyâ€"called solar energy. It radiates more energy in one day than the world uses in one year. This energy comes from within the sun itself. Like most stars, the sun is a big gas ball made up mostly of hydrogen and helium gas. The sun makes energy in its inner core in a process called nuclear fusion.
The heart of a solar collector is the absorber, which is usually composed of several narrow metal strips. The carrier fluid for heat transfer flows through a heat-carrying pipe, which is connected to the absorber strip. In plate-type absorbers, two sheets are sandwiched together allowing the medium to flow between the two sheets. Absorbers are typically made of copper or aluminum.
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.
If used correctly solar day and night lighting can provide free, high-quality lighting, and do it with less heat generation inside the house than conventional electric lighting.
The efficiency of the solar collectors is measured by the amount of sunlight hitting them, which in turn gets converted into electricity. Solar collectors with the small surface area are highly efficient.
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.
