External wall photovoltaic glue board parameters

Why do PV modules need a good thickness?

Proper thickness facilitates the installation of the sealant and allows reduced sealant stress from differential thermal movement between the PV laminate and the supporting structure. The structural bite requirement is directly proportional to the wind load on the PV module and the dimensions of the module.

Does PV laminate have a structural bonding function?

The edges of the PV laminate (glass/backsheet or glass/glass) are inserted into the cavity of a U-profile. A silicone sealant is used for fixing the laminate inside the frame and ensuring water tightness. In this case, the silicone sealant does not have a structural bonding function.

Do PV modules need to be validated?

All frame designs require validation by the module manufacturers via appropriate technical qualification tests (as detailed in the section about quality control). PV modules are commonly mounted in aluminum frames to be mechanically attached to the supporting structure.

What is the design stress for pv-8030 adhesive?

The Allowable Design Stress for Snow Load is 40,000 Pa (0.04 MPa) for FortasunTM PV-8030 Adhesive and FortasunTM PV-8303 Ultra Fast Cure Sealant and 50,000 (0.05 MPa) for FortasunTM PV-8301 Fast Cure Sealant. The Allowable Design Stress for Dead Load (DL) for FortasunTM PV-8030 Adhesive is 7,000 Pa.
