13 Aug Renewable Energy Integration & Heavy Steel Support Structures
Malaysia’s industrial sector is actively adopting green energy solutions to reduce grid power costs and meet national decarbonization goals under the National Energy Transition Roadmap (NETR). Manufacturing plants, warehouses, and logistics hubs possess expansive roof surfaces ideal for large-scale commercial and industrial (C&I) solar photovoltaic (PV) systems.
However, mounting hundreds of solar panels onto industrial factory roofs requires rigorous structural evaluation and custom-engineered steel support framing. Ensuring that sub-structures can withstand tropical storm wind loads without compromising roof integrity is vital for long-term operational safety.
Structural Engineering for Industrial Solar Installations
Retrofitting solar equipment onto existing factory buildings adds dead loads (equipment weight) and dynamic wind uplift forces to the building framework. A thorough structural audit must be conducted prior to installation.
Key structural engineering requirements include:
- Structural Roof Load Calculations: Evaluating existing roof purlins, rafters, and primary steel columns to confirm capacity for secondary solar mounting frames
- Hot-Dip Galvanized Sub-Framing: Fabricating mounting trusses using hot-dip galvanized structural steel to resist atmospheric corrosion in humid environments for 25+ years
- Utility Interconnection Compliance: Aligning structural and electrical interconnections with technical standards set by Tenaga Nasional Berhad (TNB) and SEDA Malaysia
- Precision Off-Site Prefabrication: Manufacturing pre-drilled, custom steel mounting members for rapid site assembly with minimal operational disruption to plant activities
Ground-Mounted & Elevated Solar Steel Structures
In addition to rooftop systems, manufacturing facilities with unused land frequently install ground-mounted solar arrays or elevated solar carports. These structures require driven steel pile foundations, heavy structural steel legs, and inclined steel purlins engineered to handle extreme lateral wind loads during tropical storms.

FAQs
What structural checks are needed before installing rooftop solar on a factory?
A structural review should assess the added equipment dead load, wind uplift forces, and the capacity of existing roof purlins, rafters, primary steel framing, and connections before secondary solar support structures are installed.
Why is galvanized steel commonly used for industrial solar support structures?
Hot-dip galvanized structural steel provides durable corrosion protection for support members exposed to humid outdoor conditions. This makes it well suited to rooftop, ground-mounted, and elevated solar structures designed for long service life.
