Benefits of Solar Ready Metal Roofs:
- Standing seam metal roofs are the best choice for crystalline PV and thin-film solar panels because, unlike other materials, metal offers the longest service life, making it a solar ready roof system.
- When installing a crystalline system that typically is warranted for 25 years of power generation, a building owner is going to benefit from a roofing substrate that has a greater life expectancy than that of the solar panels.
- Standing seam panels also provide a natural platform for attaching crystalline systems without any roof penetrations. Additionally, highly reflective roofs help keep rooftop temperatures cool, resulting in better performance from solar panels.
Concealed Fastener (non-penetrating) Best Practice:
- Dutch Seam
- Colonial Seam
- 1” Field-Lok
- 1 ½” Field-Lok
- 2” Field-Lok
- 2 3/8” Field-Lok
Exposed Fastener (penetrating) Good Practice:
- Corrugated – with considerations
- Grand R
- Advanta Shingle – with considerations
Types of Rooftop Solar Electric Systems
- Crystalline Panels
- Thin-Film Laminates
Considerations
- To be field applied by others
- ATAS is not responsible for the attachment choices
- Engineering review is suggested to ensure proper compatibility
- Properly clean metal panels prior to solar application for adhesive applied system
- Applied adhesive may affect integrity of metal panel
