Solar collectors are special kind of heat exchangers that transform solar radiation energy into internal energy of the transport medium. Residential panels for heat collection are referred to as flat plate solar collectors.
Performance improvement of the solar thermal power generation systems can be improved by the choosing the suitable materials and the coatings of the reflectors and receiver. The conventional reflector such as glass and the advanced reflector such as polymers based reflectors are discussed.
A flat plate solar collector consists of an absorber plate fabricated from a material which will rapidly both absorb and transfer heat from sun to the heat transfer fluid. This is usually covered with one or more sheets of glass or a plastic film. The collector lies on a bed of thermal insulation to minimise back heat loss from the plate ...
