Ground mounted photovoltaic system
Ground mounted photovoltaic system are usually large, utility-scale solar power plants. Their solar modules
are held in place by racks or frames that are attached to ground based mounting supports. Ground based
mounting supports include:
Pole mounts, which are driven directly into the ground or embedded in concrete.
Foundation mounts, such as concrete slabs or poured footings
Ballasted footing mounts, such as concrete or steel bases that use weight to secure the solar module
system in position and do not require ground penetration. This type of mounting system is well suited for
sites where excavation is not possible such as capped landfills and simplifies decommissioning or
relocation of solar module systems.
