Roof-mounted PV systems can be impractical for some people (such as homeowners whose roofs don’t get optimal sun exposure, or renters who can’t modify their roofs). This is where ground-mounted PV systems come in. As the name suggests, rather than being mounted on a roof, ground-mounted PV systems are located at ground level.
Free from the space and weight limitations of roofs, ground-mounted PV systems can be larger and more complex than roof-mounted systems. Some of them even use motors or hydraulics to adjust the angle of the solar panels, following the sun throughout the day to catch as much sunlight as possible. “Solar gardens” consist of ground-mounted PV arrays that are shared by residents of a neighborhood or used by farmers to supplement their income. Ground-mounted PV systems can also be found in public spaces, such as along highways.
