Solar thermal collector
OverviewHeating waterHeating airGenerating electricityGeneral principles of operationStandardsSee alsoExternal links
A solar thermal collector collects heat by absorbing sunlight. The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non-water heating devices such as solar cookers or solar air heaters. Solar thermal collectors are either non-concentrating or concentrating. In non-…

What is a natural circulation solar hot water system?
Obviously, when the temperature difference of Δr = r 2-r 1 is constant, the thermosiphon pressure head HT depends on the value of h. Only when the H T value is large enough to overcome the total head loss of the system, the natural circulation or thermosiphon phenomenon will occur. In other words, whether the natural circulation …
