Ground-Mounted Solar Systems For Farms and Commercial Sites

When roof space runs out, or a site doesn’t have roof space, a properly surveyed, correctly designed ground-mounted solar system can provide the scale for farms and large commercial sites.

A ground-mounted solar structure is a solar array built on open land rather than a roof, using ground-level steel or concrete framing to hold and angle the panels. Ground-mounted solar is often the practical option where roof space is limited, unsuitable or insufficient for the required system size.

A 4.5MWp ground-mounted installation is already live in Southern African agriculture. A genuine utility-adjacent scale, not a pilot project.

Why sites choose ground-mount over rooftop:

• Unlocks scale rooftop can't reach, ground-mounted solar panels keep scaling where roof area plateaus.
• Sized against your maximum demand charge, not just total usage, so you're not paying the full demand charge on top of the solar investment.
• Financial modelling comes with every proposal, not just a system size and sales call.
• Proven at utility-adjacent scale with a 4.5MWp installation, not a small commercial add-on.

Getting the site survey right before design starts

Land size and shape, soil and foundation conditions, access for construction, and orientation all factor into ground-mounted design. A structural and site survey are imperative and confirms feasibility before any design work starts. Ground-mounted PV also requires site-specific engineering. Eskom’s technical specification for a South African ground-mounted PV project calls for geotechnical assessment to inform foundation design and consideration of site loading, panel orientation and row spacing to minimise shading.

Ground-mount systems fall into two broad categories. Fixed-tilt structures hold panels at a set angle; they are stable, straightforward to engineer, and the more cost-effective options for most commercial sites.

Tracking systems adjust panel angle to follow the sun during the day for higher energy capture, but carry more engineering complexity, a higher upfront cost, and greater exposure to wind loading and maintenance. Fixed-tilt is the default recommendation for most agricultural and commercial ground-mount projects; tracking is a deliberate trade-off for sites where the yield gain justifies the added cost and complexity.

Proven at Multi-Megawatt Scale in Southern Africa

Our solar portfolio includes a 4.5MWp ground-mounted installation for Nottingham Estate, a citrus operation at Beit Bridge opposite Zimbabwe on the Limpopo River, demonstrating ground-mount design at genuine utility-adjacent scale, not a small commercial add-on.

Ground-Mount vs Rooftop vs Carport: Matching the structure to your site

Ground-mount typically allows larger system sizes and easier maintenance access than rooftop, at the cost of using land that might otherwise be productive.

Research from the University of Cape Town comparing rooftop and ground-mounted PV systems in the Western Cape found that the ground-mounted configuration achieved the strongest annual yield in the study. The research also identified ground mounting as a practical alternative where roof condition or structural strength makes rooftop installation unsuitable, while noting the potential higher upfront cost.

Elevated, open-air mounting also gives panels better airflow than a rooftop installation, keeping them cooler and improving efficiency. Where roof space is limited, rooftop or carport mounting are the alternatives.

Criteria	Ground-Mount	Rooftop	Carport
System size potential	Larger systems are practical and not limited by roof area.	Limited by available roof area.	Limited by available parking/canopy area.
Land / space trade-off	Uses land that could otherwise be productive (e.g. farmed).	No land trade-off as uses existing roof.	Uses parking area, adds shade as a bonus.
Maintenance access	Easier ground-level access for cleaning and servicing.	Requires roof access.	Ground-level access, similar to ground-mount.
Airflow / panel cooling	Open-air mounting improves airflow and efficiency.	Airflow can be restricted close to roof surface.
Best fit	Large agricultural and commercial sites with available open land.	Sites where roof space covers the required system size.	Sites wanting to combine solar with covered parking.

Sizing against maximum demand, not just total usage

On larger agricultural and industrial sites, maximum demand charges often trace back to a handful of heavy loads, irrigation pumps starting up, processing equipment cycling on, rather than overall consumption, as our agriculture and manufacturing clients often find. A ground-mounted system sized only for total annual usage can miss this entirely. An energy audit maps out exactly when those peaks hit, so system size, and any battery pairing, is set against the real driver of the charge rather than just the total bill.

Frequently Asked Questions

How much land do I need for a ground-mounted solar system?

Land requirements depend on system size, panel dimensions, row spacing, orientation, access requirements and site constraints. A site survey determines the practical footprint for the proposed system.

Is ground-mounted solar suitable for large-scale systems?

Ground-mount can be particularly suitable for larger agricultural and commercial sites where sufficient open land is available.

What soil or land conditions rule out ground-mounted solar?

Very poor foundation conditions or land needed for other productive use are the main constraints, most sites can be engineered around soil conditions with the right foundation design.

Fixed-tilt or tracking, which is better for a commercial ground-mount system?

Fixed-tilt is the right default for most sites with lower cost, simpler engineering, less exposure to wind damage and ongoing maintenance.

Tracking systems capture more energy but only make financial sense where that extra yield outweighs the higher upfront and maintenance cost.

Why does maximum demand matter for sizing my ground-mounted system?

Where maximum demand charges form a significant part of the electricity bill, sizing only against total annual kWh can miss an important cost driver.
