Commercial roofs often provide ideal space
Warehouses usually have large, unobstructed roof areas, making them attractive for solar installations. However, size alone does not confirm suitability.
Structure and load capacity
The roof structure is key. Many warehouses use lightweight steel frames or long-span trusses, which may limit load capacity. Panels, mounting systems, and ballast must be accounted for.
Access and maintenance considerations
Installation must consider safe access for maintenance, as well as how panels might affect existing equipment, ventilation or roof features.
Wind and exposure factors
Warehouse roofs can be exposed to strong winds. Panels must be fixed to withstand uplift forces, especially near edges and corners.
Orientation and layout
Maximising electricity generation requires considering roof orientation, slope, and shading. Rows of panels must be spaced appropriately to avoid shading between arrays.
Survey is essential
Even with a seemingly suitable roof, assumptions about capacity can be misleading. A structural survey evaluates load-bearing capability, condition, and safety. It is usually the only reliable way to confirm suitability for a solar installation on a warehouse roof.
