    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. These electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.

    Solar panels produce carbon free electricity when irradiated with sunlight. Often made of silicon, solar panels are made of smaller solar cells which typically have six cells per panel. Multiple solar panels strung together make up a solar array. Solar panels are generally protected by tempered glass and secured with an aluminum frame. [11] The ...

  7. Photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Photovoltaics

    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.
