Solar energy collectors are crucial for converting solar radiation into usable forms like heat or electricity. There are two main types of collectors: non-concentration and concentrating collectors. In non-concentration collectors, the collector area and absorber area are the same.
Solar thermal collectors work on the principle of converting sunlight into heat energy. The collector absorbs sunlight using a heat-absorbing material, which then heats up and transfers the heat to a fluid circulating within the collector.
A simple solar air collector consists of an absorber material, sometimes having a selective surface, to capture radiation from the sun and transfers this thermal energy to air via conduction heat transfer.
In a flat solar collector, the absorber plate is exposed to the sun and is heated by absorbing solar radiation. The heat transfer fluid, which circulates through tubes on the back of the plate, absorbs the heat from the plate. The hot fluid is transported to the storage system so that it can be used when required to heat water or air.
Residential panels for heat collection are referred to as flat plate solar collectors. Solar collectors are special kind of heat exchangers that transform solar radiation energy into internal energy of the transport medium.
This type of collector is generally used in solar power plants. A trough-shaped parabolic reflector is used to concentrate sunlight on an insulated tube (Dewar tube) or heat pipe, placed at the focal point, containing coolant which transfers heat from the collectors to the boilers in the power station.
