Traditional ground-mounted solar systems are set up by anchoring panels in the ground. These panels hold a large number of stacked panels. But as there are different types of foundations, anchoring to the ground is the most challenging part of these installations.
In case of clear soil with no debris, steel beams are simply driven into the soil and the racking system is attached to these beams. However, in situations where the soil is not visible and the ground is littered with boulders, anchor systems may be used, in which, helical piles and ground screws are driven into the debris.
Let’s take a look at the different types of ground-mounted solar systems.
Regular Ground-Mount System: This is a conventional setup in which the photovoltaic panels are held in place by racks or frames that are attached to ground-based mounting support. The mounting support may comprise of pole-mounts that are driven into the ground or embedded in concrete. Alternatively, foundation mounts such as concrete slabs or poured footings may be used.
Capped Landfill: This is an innovation in the solar sector wherein the ground-mounted systems are not fitted into the landfill grounds but are instead ballasted on it, just like they are on flat roofs. This is probably the best utilization of the surface of these otherwise abandoned landfills and brownfields. This kind of setup uses concrete and cast-in blocks to hold the system in place.
Tracking systems: To enhance energy output, tracking systems may be used. These are motorized ground-mounts that track the sun throughout the day exposing the panels to sunlight at all times. Single-axis tracking systems span the panels on long rows and only move them from east to west. Dual-axis tracking systems separate out tables of panels and follow the sun on a circular path. The latter ensures higher energy output. Trackers may be centralized, which have a single motor to move many rows of panels; or distributed, which have multiple motors to move the rows.
Carports and canopies: These are tall ground-mounts, erected mostly in parking lots of schools, universities and large business establishments. Interestingly, these can also be equipped with electric vehicle charging stations to plug in the vehicles parked underneath them.
Floating solar systems: Although not mounted to the ground, floating systems function exactly like panels positioned on a flat roof. These could be assembled on land and can float on water, with the addition of more panels. These are secured to shore mounts or floating anchors. Floating systems can help land and real estate, and are becoming increasingly popular in Asia and parts of Europe.
