Types of solar collectors3.2.1. Flat plate collectors. A flat plate collector is a type of solar collector that is commonly used in SWHSs, achieving water temperatures ranging from 40 °C up to 70 °C. It is designed to harness both direct and scattered sunlight, making it highly efficient.
Solar energy is an inexhaustible and sustainable resource with a good potential to power several applications, one of which is water heating. While several kinds of devices are used for harnessing solar energy, flat plate solar collectors are well-developed and generally more commonly used for residential and small commercial water heating …

The flat-plate systems normally operate and reach the maximum efficiency within the temperature range from 30 to 80 o C (Kalogirou, 2009), however, some new types of collectors that employ vacuum insulation can achieve …
Solar thermal collectors. 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 …
During the discharging process, the PCM freezes, transferring the stored energy to the HTF. Flat plate phase change thermal storage unit (PCTSU) is one of the popular configurations currently in use and it has been studied by many researchers (Morrison and Abdel-Khalik, 1978, Ismail et al., 1999a, Zalba et al., 2004, Saman et al., …
