  2. Stand-alone power system - Wikipedia

    en.wikipedia.org/wiki/Stand-alone_power_system

    A stand-alone power system ( SAPS or SPS ), also known as remote area power supply ( RAPS ), is an off-the-grid electricity system for locations that are not fitted with an electricity distribution system. Typical SAPS include one or more methods of electricity generation, energy storage, and regulation. Electricity is typically generated by ...

  3. Solar panel - Wikipedia

    en.wikipedia.org/wiki/Solar_panel

    A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.

  4. Distributed generation - Wikipedia

    en.wikipedia.org/wiki/Distributed_generation

    Distributed generation and storage enables the collection of energy from many sources and may lower environmental impacts and improve the security of supply. One of the major issues with the integration of the DER such as solar power, wind power, etc. is the uncertain nature of such electricity resources.

  5. Solar wind - Wikipedia

    en.wikipedia.org/wiki/Solar_wind

    The solar wind is observed to exist in two fundamental states, termed the slow solar wind and the fast solar wind, though their differences extend well beyond their speeds. In near-Earth space, the slow solar wind is observed to have a velocity of 300–500 km/s, a temperature of ~100 MK and a composition that is a close match to the corona.

  6. Variable renewable energy - Wikipedia

    en.wikipedia.org/wiki/Variable_renewable_energy

    For intermittent power sources, such as wind and solar, nameplate power is the source's output under ideal conditions, such as maximum usable wind or high sun on a clear summer day. Capacity factor , average capacity factor , or load factor is the ratio of actual electrical generation over a given period of time, usually a year, to actual ...

  7. Utility pole - Wikipedia

    en.wikipedia.org/wiki/Utility_pole

    A pole route (or pole line in the US) is a telephone link or electrical power line between two or more locations by way of multiple uninsulated wires suspended between wooden utility poles. This method of link is common especially in rural areas where burying the cables would be expensive.
