An agricultural solar mounting system for an agrivoltaic project must support photovoltaic modules while preserving the space, access, and operating conditions needed for farming. We recommend beginning with the agricultural plan—not a standard solar layout—then coordinating crop requirements, machinery movement, site conditions, electrical design, and structural loads. The right system may use elevated, fixed-tilt, or adjustable structures, depending on the farm operation and project objectives. This guide explains the main design choices and what to prepare before requesting a supplier proposal.

This guide is for developers, EPC contractors, agricultural operators, and project purchasers evaluating solar mounting structures for farmland. It is also useful when an existing solar concept needs to be adapted for crop production, livestock management, or routine farm access. The recommendations are a planning framework, not a substitute for site-specific engineering or local permitting review.
At Winture, we work with buyers on solar mounting and structural steel requirements, including cast and forged components where the design calls for them. We use project inputs to discuss feasible configurations and manufacturing scope. Final structural dimensions and connection details should be confirmed by the project’s qualified engineer against applicable codes and verified site data.
A conventional ground-mounted array is typically laid out around electrical yield, construction access, and land constraints. In an agrivoltaic project, the mounting design must also account for how people, crops, animals, and equipment will use the space. That can affect support-post locations, row spacing, structure height, module orientation, and maintenance routes.
There is no single layout that suits every crop or farm. Crop light needs vary by species, growth stage, climate, and management practice, while machinery dimensions and turning requirements depend on the operation. The agricultural operator should therefore help define the layout before the mounting system is finalized.
Start by documenting what must continue beneath and between the arrays. Record the intended crops or livestock, seasonal work schedule, equipment widths and heights, access routes, irrigation or drainage features, and any areas that must remain unobstructed. These requirements provide practical design constraints that a solar-only layout may not capture.
Use measured site information wherever possible. For example, if the tallest planned machine requires 3.5 m of unobstructed clearance, treat that as a project input to check against structural depth, cable routing, and construction tolerances—not as a universal agrivoltaic standard. The final clearance must be established with the operator and design team.
Fixed-tilt systems hold modules at a set orientation and angle. They can be suitable where a consistent layout supports both farm access and the project’s energy objectives. Elevated systems raise modules to provide more working space below, but greater height can change structural demands, foundation requirements, and installation logistics.
For initial coordination, a designer might compare a 20° module tilt with other project-specific options. This is an illustrative design value, not a recommended angle for every location. The appropriate orientation and tilt depend on site latitude, shading, energy objectives, row spacing, and the agricultural use beneath the array.
Adjustable structures can change module position, while tracking systems move modules during operation. Depending on the design, movement may help manage shading or energy production, but it also introduces mechanical components, controls, operating requirements, and maintenance considerations. Evaluate these systems against the farm’s access needs and the project’s ability to maintain moving equipment.
Material selection should reflect the structural design, exposure conditions, fabrication requirements, and expected maintenance plan. Steel components may be specified with protective finishes suited to the project environment, but the coating system and preparation should be defined by the engineer and purchaser rather than assumed from a generic product description. Connections, fasteners, posts, and brackets should be evaluated as part of the complete assembly.
Cast or forged parts may be appropriate for particular connection or load-transfer requirements, depending on geometry, quantities, and manufacturing feasibility. They are not automatically necessary for every mounting system. We recommend sharing drawings or interface requirements early so Winture can review the requested component scope and manufacturing options.

List the equipment that must pass beneath or alongside the structure, including its operating height, working width, turning path, and seasonal use. Confirm where planting, harvesting, irrigation, livestock movement, and worker access take place. If the farm plan is still evolving, identify assumptions clearly so the mounting concept can be reviewed before those assumptions become embedded in the design.
Provide the project location, topographic information, geotechnical data when available, environmental exposure, and applicable design criteria. Structural engineers use these inputs to assess wind, snow, seismic, and foundation conditions as relevant to the site. Do not select pile dimensions or embedment depth from a generic example; foundation design depends on the ground conditions and calculated loads.
As a planning example only, a concept model might test a 1.5 m foundation embedment to understand layout coordination. That figure is not a design recommendation or confirmation of capacity. A qualified engineer must determine actual foundation dimensions and installation requirements using project-specific data.
Review module dimensions, row pitch, support spacing, cable routing, inverter locations, and maintenance access together. A change in row spacing can affect both farming movement and shading, while support placement can conflict with equipment paths or irrigation lines. Include electrical and construction teams in layout reviews so that the mounting arrangement can be built and serviced as intended.
Ask each supplier to identify what is included: primary steel, secondary members, connections, fasteners, coatings, fabrication drawings, packing, and installation guidance. Check whether quoted quantities and assumptions match the latest layout and loading criteria. A low initial price may not be comparable if engineering responsibilities, finishes, or connection components differ.
Agrivoltaic mounting costs vary with structure height, steel quantity, foundation approach, material specification, finish, component complexity, order volume, and shipping destination. Custom geometry or cast and forged components may require additional design coordination and tooling review, depending on the requested part and production method. We avoid offering a universal price or lead time without reviewing the project scope.
Minimum order quantities and production schedules are likewise supplier- and product-specific. To obtain a useful quotation, provide the expected quantity, drawings or preliminary layout, technical specifications, destination, required delivery window, and any inspection or documentation requirements. If the design is not final, label the inquiry as budgetary and list the assumptions that may change.
Before choosing a supplier, check whether the team can review project drawings, clarify manufacturing boundaries, and identify missing technical inputs. Ask how the supplier handles revisions, component traceability where required, coating specifications, packaging, and export documentation. Confirm which party is responsible for structural engineering, local code compliance, foundation design, and installation supervision.
Request a quotation that clearly states the design basis and exclusions. For custom parts, confirm material requirements, tolerances, interfaces, inspection expectations, and the status of drawings before production. These steps help reduce avoidable changes after fabrication begins.
A successful agricultural solar mounting system is designed around both energy production and continued farm use. Begin with the agricultural operating plan, then coordinate structure type, clearance, row spacing, materials, foundations, and electrical access using project-specific engineering inputs. Illustrative dimensions in early discussions should never be treated as final design values.
To move from concept to a supplier discussion, prepare the site location, preliminary layout, agricultural requirements, module information, structural criteria, estimated quantity, and delivery target. We at Winture can review the manufacturing scope for solar mounting structures and relevant cast or forged components, then clarify the information needed for a project quotation. Contact our team with your drawings or preliminary requirements to discuss a suitable next step.
