  2. Solar panel - Wikipedia

    en.wikipedia.org/wiki/Solar_panel

    Solar panel. Solar array mounted on a rooftop. 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 ...

  3. 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] Concentrated solar power systems use lenses or mirrors and solar ...

    en.wikipedia.org/wiki/Solar_energy

    Electricity production. 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. Photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Photovoltaics

    Solar panels on the International Space Station. Photovoltaics ( PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors .

  6. Solar power in the United States - Wikipedia

    In 2023, utility-scale solar power generated 164.5 terawatt-hours (TWh), or 3.9% of electricity in the United States. Total solar generation that year, including estimated small-scale photovoltaic generation, was 238 TWh. [2] As of the end of 2023, the United States had 179 gigawatts (GW) of installed photovoltaic (utility and small scale) and ...

  7. Solar cell - Wikipedia

    en.wikipedia.org/wiki/Solar_cell

    Solar cell. A conventional crystalline silicon solar cell (as of 2005). Electrical contacts made from busbars (the larger silver-colored strips) and fingers (the smaller ones) are printed on the silicon wafer. Symbol of a Photovoltaic cell. A solar cell or photovoltaic cell ( PV cell) is an electronic device that converts the energy of light ...
