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 maximum value of natural solar insolation.

The replacement of a non-functional or ineffective lamp with a new, more efficient lamp.

Those privately or publicly owned establishments that generate, transmit, distribute, or sell electricity.

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

An electric current induced by radiant energy.

The thermal energy used in an industrial process.

A configuration of an electrical circuit in which the positive lead is connected to the negative lead of another energy producing, conducting, or consuming device. The voltages of each device are additive, whereas the current is not.

The change in the power available in the wind due to changes in the windspeed or velocity profile; the windpower profile is proportional to the cube of the wind speed profile.

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

Any material that has a limited capacity for conducting an electric current. Certain semiconductors, including silicon, gallium arsenide, copper indium diselenide, and cadmium telluride, are uniquely suited to the photovoltaic conversion process.

A discontinuance of electric power supply.

The process of implementing measures to reduce peak power demands on a system.

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

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

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.

For valves and fittings, implies that they are suitable for working pressures between 125 to 175 pounds per square inch.

The addition of dopants to a semiconductor.

A power source/generator that operates independently of or is not connected to an electric transmission and distribution network; used to meet a load(s) physically close to the generator.

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