4 FAQs about Requirements for seamless pressing of photovoltaic panels

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.

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.

Does PV laminate need a structural sealant?

Structural bonding of the PV laminate on supporting rails or pads with structural silicone sealant is recommended based on the proven performance of silicone sealant in the construction industry for structural glazing applications.

What is PV laminate thickness?

Thickness is the distance from the PV laminate to the supporting structure (i.e., frame, rail or pad). 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.
