It is possible to harness the energy from the sun and convert it into either electricity or heat using PV (photo-voltaic) or ST (solar thermal) technologies respectively. Solar collectors transform solar radiation into heat and transfer that heat to a medium (water, solar fluid, or air). Then solar heat can be used for heating water, backup heating systems or for heating swimming pools.
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 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.
