Lightweight 560W Solar Modules for Commercial Roofs: Key Design Considerations
Two 560W configurations
| Configuration | Published size | Published weight |
|---|---|---|
| Frameless flexible | 2260 × 1200 × 2.7 mm | 8.4 kg; approx. 3.1 kg/m² |
| Framed lightweight | 2260 × 1245 × 25 mm | 13.5 kg; approx. 4.8 kg/m² |
Roof suitability comes first
Verify roof drawings and actual condition, substrate and coating, slope or curvature, corrosion, waterproofing, drainage, fire paths and maintenance access. Lightweight does not automatically make a weak or damaged roof suitable.
Select the mounting concept
Adhesive bonding may be considered only for a validated substrate, surface preparation, adhesive system and environmental exposure. Framed modules may use compatible rails or clamps. Fixing density and edge-zone design must follow project wind requirements.
Respect curvature and handling limits
The flexible configuration’s published 0.5 m minimum bending radius is an installation boundary, not permission to fold or repeatedly flex the module. Support, handling and installation sequence should prevent creasing, local stress and damage.
Review the complete system
Include modules, fixing, cables, inverters, walkways and temporary installation loads. Confirm wind, snow, electrical, grounding, waterproofing and maintenance requirements under applicable local rules.
Use evidence within its scope
X-SOLAR reports a completed and grid-connected 2.5 MW Tangshan Jinzhou Steel Plant project using flexible modules and adhesive fixing on a continuous curved industrial metal roof. It is supplier-published project evidence, not proof that the same method suits every roof.
