  2. Photovoltaic mounting system - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_mounting_system

    Solar panels can be mounted on elevated racking so they can share space with other land uses, such as parking lots. These can provide shade for cars and reduce additional land use, but considerably more expensive than conventional ground-mounted systems due to the more extensive steel posts, footings and racks, as well as additional labor costs.

  3. Reflective surfaces (climate engineering) - Wikipedia

    en.wikipedia.org/wiki/Reflective_surfaces...

    The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).

    en.wikipedia.org/wiki/Ecliptic_coordinate_system

    In astronomy, the ecliptic coordinate system is a celestial coordinate system commonly used for representing the apparent positions, orbits, and pole orientations [1] of Solar System objects. Because most planets (except Mercury ) and many small Solar System bodies have orbits with only slight inclinations to the ecliptic , using it as the ...

    en.wikipedia.org/wiki/Circumzenithal_arc

    The CZA radius varies between 32.2° and 0°, getting smaller with rising solar altitude. It is best observed with solar altitudes of about 15°-25°; towards either extreme, it is vanishingly faint. When the Sun is observed above 32.2°, light exits the crystals through the bottom face instead, contributing to the almost colorless parhelic circle.
