  2. Maximum power point tracking - Wikipedia

    en.wikipedia.org/wiki/Maximum_power_point_tracking

    Maximum power point tracking (MPPT), [1][2] or sometimes just power point tracking (PPT), [3][4] is a technique used with variable power sources to maximize energy extraction as conditions vary [5]. The technique is most commonly used with photovoltaic (PV) solar systems but can also be used with wind turbines, optical power transmission and ...

  3. Work (physics) - Wikipedia

    en.wikipedia.org/wiki/Work_(physics)

    In science, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled. A force is said to do positive work if it has a component in the ...

  4. Power transmission - Wikipedia

    en.wikipedia.org/wiki/Power_transmission

    Power transmission is usually performed with overhead lines as this is the most economical way to do so. Underground transmission by high-voltage cables is chosen in crowded urban areas and in high-voltage direct-current (HVDC) submarine connections. Power might also be transmitted by changing electromagnetic fields or by radio waves; microwave ...

  5. Power (physics) - Wikipedia

    en.wikipedia.org/wiki/Power_(physics)

    t. e. Power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. Power is a scalar quantity. Specifying power in particular systems may require attention to other quantities; for example, the power involved in moving a ground vehicle ...

  6. Wireless power transfer - Wikipedia

    en.wikipedia.org/wiki/Wireless_power_transfer

    Generic block diagram of a wireless power system. Wireless power transfer (WPT; also wireless energy transmission or WET) is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, an electrically powered transmitter device generates a time-varying electromagnetic field that transmits ...

  7. Energy transformation - Wikipedia

    en.wikipedia.org/wiki/Energy_transformation

    Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. [1] In physics, energy is a quantity that provides the capacity to perform work or moving (e.g. lifting an object) or provides heat. In addition to being converted, according to the law of conservation of energy, energy is ...

  8. Exergy - Wikipedia

    en.wikipedia.org/wiki/Exergy

    Exergy, often referred to as "available energy " or "useful work potential", is a fundamental concept in the field of thermodynamics and engineering. It plays a crucial role in understanding and quantifying the quality of energy within a system and its potential to perform useful work. Exergy analysis has widespread applications in various ...

  9. Photovoltaic system - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_system

    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 ...
