The amount (percent) of light that is reflected by a surface relative to the amount that strikes it.

A corporation, person, agency, authority or other legal entity that owns and/or operates facilities for the generation, transmission, distribution or sale of electricity primarily for use by the public.

A solar energy concentrating technology that uses a linear receiver that tracks the focal area of a reflector or array of reflectors.

The amount of heat in a quantity of matter at a specific temperature and pressure.

A measure of the effective cooling capacity of a refrigerator, expressed in Btu per hour or in tons, where one (1) ton of capacity is equal to the heat required to melt 2,000 pounds of ice in 24 hours or 12,000 Btu per hour.

An electric current induced by radiant energy.

The generation of an electric current, when two conductors of different metals are joined at their ends to form a circuit, with the two junctions kept at different temperatures.

A unit or measure of solar radiation; 1 calorie per square meter or 3.69 Btu per square foot.

A type of cooling system that uses a charging and discharging cycle with a thermal or latent heat storage subsystem.

The difference between the total cooling effect and the dehumidifying effect.

A component of a water heating system that opens at a designated temperature or pressure to prevent a possible tank, radiator, or delivery pipe rupture.

A type of solar thermal collector in which a heat transfer fluid drips out of header pipe at the top of the collector, runs down the collector absorber and into a tray at the bottom where it drains to a storage tank.

A device or media that absorbs heat for storage for later use.

A wheel that is designed to use the weight and/or force of moving water to turn it, primarily to operate machinery or grind grain.

A device that transfers heat by the continuous evaporation and condensation of an internal fluid.

Power generated by a utility unit that operates at a very low capacity factor; generally used to meet short-lived and variable high demand periods.

Energy generated from an electromagnetic field produced by an electric current flowing through a superconducting wire kept at a specific low temperature.

A way of joining photovoltaic cells or modules by connecting positive leads together and negative leads together; such a configuration increases the current, but not the voltage.

The amount that the voltage, current, and/or power output of a solar cell changes due to a change in the cell temperature.
