  2. Roll Out Solar Array - Wikipedia

    en.wikipedia.org/wiki/Roll_Out_Solar_Array

    Traditional solar panels used to power satellites are bulky, with heavy panels folded together using mechanical hinges. Given a space-bound payload is limited in its mass and volume by necessity, ROSA is 20 percent lighter (with a mass of 325 kg (717 lb)) [3] and one-fourth the volume of rigid panel arrays with the same performance.

  3. Solar panel - Wikipedia

    en.wikipedia.org/wiki/Solar_panel

    Solar panels are also known as solar cell panels, solar electric panels, or PV modules. Solar panels are usually arranged in groups called arrays or systems . A photovoltaic system consists of one or more solar panels, an inverter that converts DC electricity to alternating current (AC) electricity, and sometimes other components such as ...

  4. Solar-cell efficiency - Wikipedia

    en.wikipedia.org/wiki/Solar-cell_efficiency

    Usually solar panels are exposed to sunlight for longer than this in a given day, but the solar irradiance is less than 1000 W/m 2 for most of the day. A solar panel can produce more when the Sun is high in Earth's sky and produces less in cloudy conditions, or when the Sun is low in the sky. The Sun is lower in the sky in the winter.

  5. Solar cell - Wikipedia

    The price of solar panels fell steadily for 40 years, interrupted in 2004 when high subsidies in Germany drastically increased demand there and greatly increased the price of purified silicon (which is used in computer chips as well as solar panels). The recession of 2008 and the onset of Chinese manufacturing caused prices to resume their ...

  6. Solar still - Wikipedia

    en.wikipedia.org/wiki/Solar_still

    A solar still distills water with substances dissolved in it by using the heat of the Sun to evaporate water so that it may be cooled and collected, thereby purifying it. They are used in areas where drinking water is unavailable, so that clean water is obtained from dirty water or from plants by exposing them to sunlight.

  7. Solar power in China - Wikipedia

    en.wikipedia.org/wiki/Solar_power_in_China

    The solar park has an installed capacity of 2.2 GW, making it the second-largest solar plant in the world as of 2021, behind the Bhadla Solar Park in India. The solar plant is connected to the world's first ultra-high voltage power line which gets all of its power from renewable energy and is capable of transferring power over 1000 km.
