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 panel is composed of a package of photovoltaic cells. It can be used in a larger photovoltaic system for generating and supplying electric energy to residents and other commercial applications. Solar radiation that falls directly on the solar panel is converted into direct current. The electric energy output of each panel varies from 100 to 320 W.
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.
In the dark depths of winter, there's nothing like a sunny day to set your spirits soaring. Trees and flowers reach for the sky, cats bask in the warm sunlight, and even humans take a time to sit in gardens or stroll along the beach. The message is clear: everything living loves natural light! So wouldn't it be great if we could use more of it in our buildings instead of the sterile, artificial electric light we usually have to put up with?
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.
