2.2 Types and Elements of Concentrating Collectors
2.2 Types and Elements of Concentrating Collectors. Any general setup for the conversion of the solar energy includes a receiver - a device that is able to convert the solar radiation into a different kind of energy. This can be either a heat absorber (to harvest thermal energy) or a photovoltaic cell (to convert light to electric energy).
Solar Heating and Cooling Technologies
Evacuated tube solar collectors; Concentrating solar systems; In addition to the solar thermal technologies above, ... Transpired solar air collectors typically consist of a dark-colored, perforated metal cladding material mounted on an existing wall on the south side of a building.
