No. When fixing solar panel brackets, the ISOLINE® sheets must be treated as waterproofing components only, not as a structural component. Structural components (like PV brackets) must always fix to rafters.
How to waterproof at this section:
To integrate solar panels into the ISOLINE® LOW LINE roof structure, follow the below steps:
Use Hanger Bolt fixing or similar
Use a suitable length depending on the PV bracket and type of tile
Screw in the bolt until the seal has made good contact with the ISOLINE® sheet. (Do not over tighten or force the sheet corrugations to collapse).Only penetrate the ISOLINE® sheet at the top of the corrugations.
Always fix structural components to rafters. If you need to fix where a rafter is not present, you must add a structural component (rafter or similar).
Note: When fixing solar panel brackets you must treat the ISOLINE® sheets as waterproofing components only, not as a structural component.
Rafters will typically be the main structural components of a pitched roof.
IMPORTANT NOTE:
This guide is for waterproofing purposes only.
For structural considerations please consult a PV Specialist / Structural Engineer
All fixings/brackets are by others.
