Solar PV mounting structure calculation
PV mounting structures are light but large; wind tries to lift them. We calculate roof and ground systems for wind, snow and connections.
Why it matters
Inclined arrays act like wings, with high uplift at edges and corners. Roof systems are governed by added load and fixings, ground systems by foundations and stability.
We check rails, posts, clamps and screws, sliding and overturning for ballasted systems, and state the loads transferred to the roof.
Systems
- Trapezoidal and sandwich panel roofs
- Ballasted flat roof systems
- Ground-mounted fixed tilt
- Carport structures
- Building-integrated PV
Standards
- EN 1991-1-4
- EN 1991-1-3
- EN 1999-1-1
- EN 1993-1-1

Solar Mounting Structures
Do you check the existing roof as well?
We report the mounting structure and the loads transferred to the roof. The adequacy of the existing building structure needs a separate assessment, which we state clearly when required.
