The utilities network of conductors, substations and equipment that distributes electricity from multiple generation points to the consumer.
A device that converts electricity from Direct Current (DC) to Alternating Current (AC).
Unit of energy used to perform work (energy and work are equivalent in units, energy being the potential value and work the achieved value).<br><br>

Thermal Unit: 1 kWh = 3,400 BTU. Can be compared to 860 calories (food value)
Refers to equipment that is powered by electricity. Usually expressed in terms of amperes or watts. In an electrical circuit, any device or appliance that uses power (such as a light bulb or water pump).
The measurement of electricity produced by a solar generator at noon on a sunny day, under predetermined standard conditions.
The actual (physical) particle unit of light, as the electron is of electric charge and the atom and molecule are of matter. Light has both wave properties and particle properties. Violet light has a relatively short wavelength and higher energy in its photons; red light has a longer wavelength, lower-energy photons. The wavelength and/or energy spectrum of the sun extends in both directions beyond the visible range of light, and the silicon module solar cell can capture some energy in both of these invisible zones. Photons not captured by the cell are either reflected or converted to heat in the solar array.
A device composed of specially prepared semiconductor material or material combinations exhibiting the ability to convert incident solar energy directly into electrical energy.
The electrical equipment used to convert power from a photovoltaic array into a form suitable for subsequent use. Loosely, a collective term for inverter, transformer, voltage regulator and other power controls.
An instrument used to measure broadband solar intensity on a surface measured in watts per meter squared (w/m<sup>2</sup>).
