New buildings should be designed to optimise solar energy generation so that photovoltaic and solar thermal can be integrated without costly structural changes later.
With building rules across the EU are tightening around solar-readiness, here’s a quick checklist to help you move your solar projects forward faster (and avoid late-stage redesigns):
☑️ Load path clarity: confirm the roof build-up and structural capacity early, including wind and snow actions.
☑️ Waterproofing strategy: decide upfront how you’ll manage penetrations, cable routes and roof detailing.
☑️ Fire and access: coordinate fire planning and safe maintenance access routes with the wider roof package.
☑️ Standardisation: reduce component variety where possible so installation teams can work faster and with fewer surprises.
☑️ Documentation: keep calculations, plans and bills of materials consistent from concept to procurement.
If you’re planning 2026-27 pipelines, now is the moment to align roof design, mounting approach and documentation so that solar can be deployed on programme.
