  2. Solar power - Wikipedia

    en.wikipedia.org/wiki/Solar_power

    Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current . [ 2 ]

  3. Maximum power point tracking - Wikipedia

    en.wikipedia.org/wiki/Maximum_power_point_tracking

    Solar inverters convert DC power to AC power and may incorporate MPPT. The power at the MPP (P mpp) is the product of the MPP voltage (V mpp) and MPP current (I mpp). In general, the P-V curve of a partially shaded solar array can have multiple peaks, and some algorithms can get stuck in a local maximum rather than the global maximum of the ...

    en.wikipedia.org/wiki/Solar_energy

    Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current . [ 63 ]

  5. Shockley–Queisser limit - Wikipedia

    en.wikipedia.org/wiki/Shockley–Queisser_limit

    There is an optimal load resistance that will draw the most power from the solar cell at a given illumination level. Shockley and Queisser call the ratio of power extracted to I sh V oc the impedance matching factor, m. (It is also called the fill factor.) The optimum depends on the shape of the I versus V curve.

  6. Outline of solar energy - Wikipedia

    en.wikipedia.org/wiki/Outline_of_solar_energy

    Solar power tower – also known as 'central tower' power plants or 'heliostat' power plants or power towers, is a type of solar furnace using a tower to receive the focused sunlight. Solar-powered desalination unit – a device capable of harnessing energy from the sun to produce portable water from saline water through direct or indirect methods.

  7. Photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Photovoltaics

    A photovoltaic system, or solar PV system is a 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 directly convert sunlight into electricity, a solar inverter to change the electric current from DC to AC, as well as mounting ...

  8. Energy harvesting - Wikipedia

    en.wikipedia.org/wiki/Energy_harvesting

    Energy harvesting (EH) – also known as power harvesting, energy scavenging, or ambient power – is the process by which energy is derived from external sources (e.g., solar power, thermal energy, wind energy, salinity gradients, and kinetic energy, also known as ambient energy), then stored for use by small, wireless autonomous devices, like those used in wearable electronics, condition ...

  9. Theory of solar cells - Wikipedia

    en.wikipedia.org/wiki/Theory_of_solar_cells

    However, the solar frequency spectrum approximates a black body spectrum at about 5,800 K, [1] and as such, much of the solar radiation reaching the Earth is composed of photons with energies greater than the band gap of silicon (1.12eV), which is near to the ideal value for a terrestrial solar cell (1.4eV).
