A solar energy system designed to provide heat to individual rooms in a building.

The total distribution of electromagnetic radiation emanating from the sun. The different regions of the solar spectrum are described by their wavelength range. The visible region extends from about 390 to 780 nanometers (a nanometer is one billionth of o ...

Solar energy conversion technologies that convert solar energy to electricity, by heating a working fluid to power a turbine that drives a generator. Examples of these systems include central receiver systems, parabolic dish, and solar trough.

A solar thermal technology that uses a modular mirror system that approximates a parabola and incorporates two-axis tracking to focus the sunlight onto receivers located at the focal point of each dish. The mirror system typically is made from a number of ...

Solar energy systems that collect or absorb solar energy for useful purposes. Can be used to generate high temperature heat (for electricity production and/or process heat), medium temperature heat (for process and space/water heating and electricity gene ...

The period marked by successive crossing of the earth's meridian by the sun; the hour angle of the sun at a point of observance (apparent time) is corrected to true (solar) time by taking into account the variation in the earth's orbit and rate of rotatio ...

The amount of solar energy that passes through a glazing material, expressed as a percentage.

A type of solar thermal system where sunlight is concentrated by a curved reflector onto a pipe containing a working fluid that can be used for process heat or to produce electricity. The world's largest solar thermal electric power plants use solar troug ...

Solar Two is a retrofit of the Solar One project (see above). It is demonstrating the technical feasibility and power potential of a solar power tower using advanced molten-salt technology to store energy. Solar Two retains several of the main components ...

Name sometimes used in place of pyranometer as a generic term.

A glazed structure, such as greenhouse or "sunspace."

Safety Of Life At Sea (International Convention)

Reduction in mechanical properties of a metal as a result of local penetration of solder along grain boundaries.

A wind which blows on the beam thus requiring no tacking or trimming of the sails. It will take a sailing vessel somewhere without requiring much nautical ability.

A metallic pad, usually embedded in concrete, on which the compressor feet are mounted.

An electromechanical device composed of a coil of wire wound around a cylinder containing a bar or plunger, that when a current is applied to the coil, the electromotive force causes the plunger to move; a series of coils or wires used to produce a magnet ...

An automatic valve that is opened or closed by an electromagnet.

Any fuel that is in solid form, such as wood, peat, lignite, coal, and manufactured fuels such as pulverized coal, coke, charcoal, briquettes, pellets, etc.

A single, solid, homogeneous crystalline phase containing two or more chemical species.

The occurrence of embrittlement in a material below the melting point of the embrittling species. See also liquid-metal embrittlement.
