Gluing the photovoltaic panel surface

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.

How do PV modules work?

PV modules are commonly mounted in aluminum frames to be mechanically attached to the supporting structure. 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.

How do you seal PV laminate?

Prime the surface to receive sealant if required. Place the PV laminate to be framed or bonded in the correct position. Care must be taken to not contaminate cleaned surfaces during any phase of production. If contamination occurs, surfaces must be cleaned again. Apply sealant into the joint cavity.

How do you use two-part PV sealants?

Two-part PV sealants from DuPont require correct pumping and mixing by the sealant user to achieve intended performance. State-of-the-art technology for the application of two-part sealants uses an appropriate pumping, metering and mixing machine with either a dynamic or static mixer. There are several different suppliers for such equipment.
