The unit of measure that indicates how much electricity flows through a conductor. It is like using cubic feet per second to measure the flow of water. For example, a 1,200-wat [..]

A collection of electrically connected photovoltaic (PV) modules.

Horizontal angle measured clockwise from true north; 180° is true south.

Batteries are often sold with a PV system. The primary purpose is to store the electricity not immediately used, which could be used at some later time. With net metering, the [..]

Building Integrated Photovoltaics; A term for the design and integration of PV into the building envelope, typically replacing conventional building materials. This integration [..]

A device that produces electricity from light. Cells are the building block for modules.

One or more conductors through which electricity flows.

The flow of electric charge in a conductor between two points having a difference in potential (voltage).

The amount of power your site uses. Load may be expressed in kilowatts (capacity) or kilowatt-hours (energy). A site's peak kilowatts generally refers to when electric [..]

The discharge and subsequent charge of a battery.
