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. This heated air is then ducted to the building space or to the process area where the heated air is used for space heating or process heating needs. Functioning in a similar manner as a conve

The solar collector efficiency depends on factors such as the optical characteristics of the collector, incident solar radiation, and thermal losses. In the present study, the efficiency values were highest during peak solar hours, suggesting that the Ni-Co coating was effective in capturing and converting solar radiation into heat energy.

Solar Collector

These collectors focus solar radiation on a line focus where the absorber is located. A reflecting spherical or paraboloidal bowl is used when temperatures on the order of 250 to 500°C are needed. For extremely high temperatures, a large field of tracking mirrors (called heliostats) is used to concentrate solar radiation on a receiver that is

Application of solar thermal collectors for energy consumption in

Solar collectors are energy harvesting devices that convert solar radiation into heat energy and transport the generated heat via a working fluid (heat transfer fluid) in a riser pipe to a storage tank [21], [22].The solar energy transported by the working fluid can also be utilised directly for space heating, equipment conditioning and other thermomechanical applications [23].
