What Is the Minimum Bending Radius of a Flexible Solar Module? XSFM-560-T2 Curved-Roof Guide

Direct answer: The published minimum bending radius of the XSFM-560-T2 560W frameless flexible configuration is 0.5 m. This is an installation curvature limit under suitable project conditions—not permission to fold, crease or repeatedly bend the module.

What Minimum Bending Radius Means

The value describes the tightest smooth curve that may be evaluated during installation. A larger radius is gentler. The roof must have a continuous profile without abrupt folds, local steps or unsupported areas that would introduce abnormal stress.

What It Does Not Mean

  • The module is not designed to be folded.
  • It is not intended for repeated or cyclic bending.
  • A 0.5 m radius does not prove compatibility with every curved roof.
  • The value does not replace structural, wind, substrate or fixing-system assessment.

Curved-Roof Design Checks

  1. Measure the actual roof radius and profile continuity.
  2. Check roof sheets, purlins, structural capacity and local weak areas.
  3. Confirm substrate condition and compatibility with the proposed fixing system.
  4. Review wind suction at roof edges and corners, plus local snow conditions.
  5. Coordinate drainage, waterproofing, cable routes and maintenance access.

Project Evidence

The completed and grid-connected 2.5 MW Tangshan Jinzhou Steel Plant project uses X-SOLAR flexible modules with an adhesive fixing system on a continuous curved industrial metal roof. It provides a real project reference, but every new roof still requires independent assessment.
