A Solar Water Heating System (SWHS) is a device that makes
the available thermal energy of the incident solar radiation for use
in various applications by heating the water. Hot water is essential
both in industries and domestic applications. It is required for
taking baths, washing clothes and utensils, and other domestic
purposes in both the urban and rural areas. Hot water is also
required in large quantities in hotels, hospitals, hostels, and
industries such as textile, paper and food processing, dairy, and
edible oil. The SWHS consists of solar thermal collectors, water
tanks, interconnecting pipelines, and the water, which gets circulated
in the system.
