The elements and compounds that result from the combustion of a fuel.

Category:Energy Terms

The angle between the sun's apparent position in the sky and true south, as measured on a horizontal plane.

Category:Energy Terms

See Solar Module.

Category:Energy Terms

Energy available due to position.

Category:Energy Terms

The apparent angle of the sun north or south of the eath's equatorial plane. The earth's rotation on its axis causes a daily change in the declination.

Category:Energy Terms

A curve illustrating the variation or spectral irradiance with wavelength.

Category:Energy Terms

The process of modifying the characteristics of electrical power (for e.g., inverting dc to AC).

Category:Energy Terms

The structure (in a residential heating appliance, industrial furnace, or power plant) into which combustion gases flow and are contained until they are emitted to the atmosphere.

Category:Energy Terms

A federally funded institute, created by the Solar Energy Research, Development and Demonstration Act of 1974, that conducted research and development of solar energy technologies. Became the National Renewable Energy Laboratory (NREL) in 1991.

Category:Energy Terms

A connection or link between power systems that enables them to draw on each other's reserve capacity in time of need.

Category:Energy Terms

A device used to collect, absorb, and transfer solar energy to a working fluid.

Category:Energy Terms

A solar photovoltaic device that produces a specified power output under defined test conditions, usually composed of groups of solar cells connected in series, in parallel, or in series-parallel combinations.

Category:Energy Terms

The process of distributing electricity; usually defines that portion of an electrical utility's power lines between a utility's power pole and transformer and a customer's point of connection/meter.

Category:Energy Terms

A device that achieves very high temperatures by the use of reflectors to focus and concentrate sunlight onto a small receiver.

Category:Energy Terms

The amount of solar radiation, both direct and diffuse, received at any location.

Category:Energy Terms

The ratio of energy reflected from a surface in a given waveband to the energy incident in that waveband.

Category:Energy Terms

An interior or exterior movable panel that operates on hinges or slides into place, used to protect windows or provide privacy.

Category:Energy Terms

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.

Category:Energy Terms

An apparatus that replicates the solar spectrum, and used for testing solar energy conversion devices.

Category:Energy Terms

The gas resulting from the combustion of a fuel that is emitted to the flue.
