  2. Solar tracker - Wikipedia

    en.wikipedia.org/wiki/Solar_tracker

    A solar tracker is a device that orients a payload toward the Sun. Payloads are usually solar panels , parabolic troughs , Fresnel reflectors , lenses , or the mirrors of a heliostat . For flat-panel photovoltaic systems , trackers are used to minimize the angle of incidence between the incoming sunlight and a photovoltaic panel , sometimes ...

  3. Sun sensor - Wikipedia

    en.wikipedia.org/wiki/Sun_sensor

    Analog and digital Sun sensors, in contrast, indicate the angle of the Sun by continuous and discrete signal outputs, respectively. [2] In typical Sun sensors, a thin slit at the top of a rectangular chamber allows a line of light to fall on an array of photodetector cells at the bottom of the chamber. A voltage is induced in these cells, which ...

    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 ...

  5. Altazimuth mount - Wikipedia

    en.wikipedia.org/wiki/Altazimuth_mount

    In the largest telescopes, the mass and cost of an equatorial mount is prohibitive and they have been superseded by computer-controlled altazimuth mounts. [5] The simple structure of an altazimuth mount allows significant cost reductions, in spite of the additional cost associated with the more complex tracking and image-orienting mechanisms. [6]

  7. Solar street light - Wikipedia

    en.wikipedia.org/wiki/Solar_street_light

    The solar panel is one of the most important parts of a solar street light, as the solar panel can convert solar energy into electricity that the lamps can use. There are two types of solar panels commonly used in solar street lights: monocrystalline and polycrystalline. The conversion rate of mono-crystalline solar panels is much higher than ...
