Solar collectors employ a heat-exchanging fluid to convert solar energy to thermal energy. The absorber plate of the collector captures solar energy and transfers it to the absorber fluid, increasing its internal energy, which may subsequently be used for various purposes.
Different equipment and technologies, such as photovoltaic and solar thermal collectors, can carry out this energy conversion process. Solar collectors employ a heat-exchanging fluid to convert solar energy to thermal energy.
The concentrating collector technologies increases, the heat absorption by a solar collector, wherein the parabolic reflecting surface is attached with sun tracking to focus on a smaller absorption area, which increases the radiation flux.
