Ground-Mounted Solar Power for Factories and Industrial Facilities

Ground-mounted solar power is an option for industrial facilities where suitable land is available, and the factory roof presents structural, operational, or expansion constraints. The plant is installed on dedicated mounting structures at ground level and designed around the site's electrical load, land conditions, and grid connection requirements.

Why factories choose ground-mounted solar power over rooftop systems

For an industrial user, the choice between ground-mounted and rooftop begins with site conditions.An existing factory roof may have load limitations that restrict the installation of modules and supporting structures. Roof age is another consideration, particularly where repairs or replacement may be required during the operating life of the solar plant.Future expansion also matters. A manufacturer planning additional production blocks, utilities or warehouse space may prefer to keep roof areas available for operational changes.Where suitable land is available within or near the industrial site, ground mounting can provide greater flexibility in plant layout, module orientation, access and future site planning.

Land Requirement Per MW and Layout Considerations

Ground-mounted solar typically requires between 4 and 5 acres per MW, though the exact figure depends on module and tracker technology, row spacing and site topography  Layout affects land efficiency directly. Row spacing must account for inter-row shading as the sun angle changes through the day and across seasons, so tighter spacing increases land utilisation but can reduce annual generation if shading losses rise. Site shape, access roads and setback requirements also reduce the usable area within a plot.

Mounting structures and foundation selection

The mounting arrangement determines module orientation and influences land use, energy generation profile, and mechanical design.

Fixed tilt

Fixed tilt structures hold modules at a predetermined angle. The arrangement has no routine tracking movement and is designed around site orientation, solar resource, and structural requirements.

Seasonal tilt

Seasonal tilt systems allow the module angle to be adjusted at selected intervals. Their suitability depends on the operating strategy, structure design and maintenance requirements of the project.

Single-axis tracking

Single-axis tracking changes module orientation during the day along one axis. Site geometry, terrain, operating requirements and mechanical complexity must be considered before selecting this arrangement.

Single-axis trackingRequires layout suitable for moving structuresTerrain, spacing, drive system and maintenance access

Foundation Types and Soil Conditions

The foundation anchoring the mounting structure is selected based on soil conditions at the site. Common foundation types include driven piles, where steel posts are driven directly into the ground, and are typically suited to softer soils with good load-bearing depth. Concrete footings, cast in place or precast, suit sites with harder or rockier ground where piling is impractical. Ballasted foundations, which use weighted concrete blocks rather than penetrating the ground, are used where excavation is restricted, such as sites with underground utilities or contamination concerns. A geotechnical assessment during the feasibility stage determines which foundation type applies.

How the factory load profile determines system sizing

Solar for factory applications should be sized against the facility's actual electrical demand rather than available land alone.Engineers assess the load profile to understand when electricity is consumed during operating hours. Daytime demand, operating shifts, seasonal production changes, and planned capacity expansion all influence the appropriate system size.The design must also consider how much generation the facility can consume directly and how the proposed grid connection arrangement will handle generation under different operating conditions.

Grid connection options for industrial solar

A Behind-the-Meter (BTM) system connects on the consumer side of the electrical connection and primarily serves on-site demand.Net metering allows eligible exported generation and imported electricity to be accounted for under the applicable regulatory framework. Eligibility and treatment depend on prevailing regulations.Open access is another route for supplying solar electricity through the grid. Its commercial and regulatory structure requires separate evaluation.

What an EPC Scope Covers

An EPC contract for ground-mounted solar typically spans several stages. Design covers site layout, structural and electrical engineering, and yield estimation. Procurement covers sourcing of modules, inverters, mounting structures, and balance-of-system components. Civil works cover site preparation, foundation installation, and access infrastructure. Electrical works cover module mounting, wiring, inverter installation, and connection to the switchyard or substation. Commissioning covers testing, grid synchronisation, and handover documentation. Advait Greenergy has delivered more than 2500 MWp of solar under this scope, including projects for clients such as Adani and KP Group.

Typical Timeline for a Ground-Mounted Solar Project 

The project schedule depends on site readiness, engineering requirements, equipment availability, approval processes, and grid connectivity.A typical sequence is:Feasibility and site assessment → engineering and design → approvals and procurement → civil and structural works → electrical installation → testing → grid connection → commissioning.Timeline varies with system size and site conditions, and utility-scale projects extend this further with grid approval processes. Advait Greenergy works on commercial, industrial, and utility-scale solar projects starting at roughly 100 kW, has delivered more than 2050 MWp of solar with clients including Adani and KP Group
