Solar thermal collectors are devices that absorb solar radiation and convert it into heat. Then, the generated heat is transferred by a HTF to provide the heat demand of a specific application . A comprehensive description of solar thermal collectors is provided by Kalogirou . Fig. 2.4 shows a classification of solar thermal collectors.
Solar thermal collectors can be divided into four categories as per their applicability in the range of temperatures: (i) Flat plate collectors (FPCs), (ii) Evacuated tube collectors (ETCs), (iii) Concentrating collectors, (iv) Hybrid (combination of two technological advancements) collectors .
The main parts of a collector include a see-through cover, an absorbing plate, and insulation. These components work together to increase the collection of solar heat. What are the main applications of solar collectors? Solar collectors are used in a variety of ways, from heating water at home to producing power in large plants.
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.
As solar energy in an active solar system is typically collected at a location remote from the spaces requiring heat, solar collectors are normally associated with central systems. Solar water-heating collectors may also provide heated water that can be used for space cooling in conjunction with an absorption refrigeration system.
A study by the International Renewable Energy Agency (IRENA) indicates that solar thermal collector systems can cover between 50% and 80% of the hot water needs in a typical home depending on the geographic location and the efficiency of the system.
