Optical overheating protection

OverviewWorking principleAngular DependenceApplicationsExternal links

With all solar thermal collector systems there is a potential risk that the solar collector may reach an equilibrium or stagnation temperature higher than the maximum safe operating temperature. Various measures are taken for optical overheating protection. Stagnation temperatures are encountered under conditions of high radiation while no heat transfer fluid is flowing through the collector, for example during power failures, component failures, serv

6 FAQs about [Solar Collector Protection]

What does a solar collector do?

Solar collectors form the core of a solar thermal system. As their name suggests, they collect the sun's rays. This is then followed by conversion into usable heat, which can then be used to heat domestic hot water or as a central heating backup in the home.

Are solar thermal collectors safe?

Solar thermal collector systems have a potential risk of reaching an equilibrium or stagnation temperature higher than the maximum safe operating temperature. For optical overheating protection, various measures are taken.

What is a solar thermal collector?

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.

What type of reflector should a solar collector have?

The conventional reflector such as glass and the advanced reflector such as polymers based reflectors are discussed. The coating used in this types of Reflectors for the coatings for the protection from the dirt and corrosion are mentioned. Receiver of the solar collector should have the high specular absorbtance.

Which type of collector is used in solar power plants?

This type of collector is generally used in solar power plants. A trough-shaped parabolic reflector is used to concentrate sunlight on an insulated tube (Dewar tube) or heat pipe, placed at the focal point, containing coolant which transfers heat from the collectors to the boilers in the power station.

What is a glazed solar collector?

Glazed Solar Collectors (recirculating types that are usually used for space heating). Air typically passes along the front or back of the absorber plate while scrubbing heat directly from it. Heated air can then be distributed directly for applications such as space heating and drying or may be stored for later use.
