For agrivoltaics steel structures, success is rarely about whether it can be built — it hinges on whether load assumptions match real service conditions and whether connection details suit the operating environment. Agronomic requirements and rack layout must be coordinated, and foundation work must not damage the arable soil layer
Agrivoltaics Steel Structures: Service Conditions Shape the Design
Elevated PV racks plus farming space; must accommodate machinery passage and daylight
That's why agrivoltaics projects can't rely on generic drawings: with the same span, different load conditions and service environments can call for entirely different structural and envelope solutions. We usually start with a requirements brief — use, span, cranes, equipment and site conditions — and then recommend a structural concept.
Recommended structural system
Elevated steel truss racks with 3-5 m clear height, in 8-20 m bay units. This is currently the best-balanced option for agrivoltaics projects in terms of cost-effectiveness and reliability — it controls steel weight while allowing fast on-site assembly.
Key parameters to confirm first
Wind uplift on racks is significant; uplift resistance and foundation pull-out must be verified against local wind pressure. Once these parameters are fixed, the steel weight and budget range are essentially locked in; the rest of the design is optimization within that framework.
Design & Construction Key Points
Agronomic requirements and rack layout must be coordinated; foundation work must not damage the arable soil layer
Our approach is to build these constraints into the design input at the concept stage rather than patching them in during construction drawings. Experience on overseas projects means we deliver calculation notes, material certificates and inspection records together with the drawings, ready for permitting, acceptance and third-party inspection.
Cost Structure & Key Drivers
The cost of agrivoltaics projects consists mainly of four parts: the primary steel structure (steel weight and fabrication), the envelope system (roof and wall panels, insulation, daylighting and ventilation), foundations and floor slabs, and shipping and installation. The primary structure typically accounts for 40%-60% and the envelope 20%-35%, with the rest going to foundations, slabs, shipping and installation.
Key cost drivers: span and column spacing (steel weight rises noticeably with each span step), crane configuration, corrosion protection class (C4-C5 required in coastal or chemical environments), and whether mezzanines or equipment platforms are included.
