    A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...

  6. Electricity generation - Wikipedia

    en.wikipedia.org/wiki/Electricity_generation

    Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery ( transmission, distribution, etc.) to end users or its storage, using for example, the pumped-storage method.

  7. History of operating systems - Wikipedia

    en.wikipedia.org/wiki/History_of_operating_systems

    Computer operating systems (OSes) provide a set of functions needed and used by most application programs on a computer, and the links needed to control and synchronize computer hardware. On the first computers, with no operating system, every program needed the full hardware specification to run correctly and perform standard tasks, and its ...

  8. Distributed generation - Wikipedia

    en.wikipedia.org/wiki/Distributed_generation

    Distributed energy resource ( DER) systems are small-scale power generation or storage technologies (typically in the range of 1 kW to 10,000 kW) [18] used to provide an alternative to or an enhancement of the traditional electric power system. DER systems typically are characterized by high initial capital costs per kilowatt. [19]
