Solar panel sealing tape

How to seal between solar panels using a silicone sealant?

Below is a step-by-step procedure of how to seal between solar panels using a silicone sealant: Clean the surface to get rid of tape or any other material before starting the sealing process. Add the silicone sealant at the point where the glass meets with the frame or whichever edge protection is present.

What is solar edge seal tape?

Trusted by PV module manufacturers for more than 20 years, this solar edge seal tape protects cells, connections and transparent conductive oxide coatings from moisture ingress, helping improve panel longevity and maximize power.

How do you seal a solar panel?

Make sure the surface is clean and free of any tape or other materials before applying silicone sealant to seal solar panels. Add some silicone at the corner of the glass where it meets with the frame or any other added edge protection. Make sure that you do not apply too much silicon since it will overflow after installing the panel back.

What is pumpable solar edge tape (PSET)?

Traditionally, the edge seal process is done with a tape that seals the components together. The tape is applied manually or automatically. While tape has traditionally been the sealant of choice, a newer technology called pumpable solar edge tape (PSET) has proven itself to be a high-quality successor for this important manufacturing step.

What is set solar edge sealant?

SET is a solar edge sealant, pre-extruded to tape dimensions specific to your module design needs. Tape packages are easier to handle and scalable from intermittent use to high-volume automation. Want to learn more?

Why is edge seal tape overlapping?

In order to ensure complete edge seal coverage around the perimeter of the solar panel, edge seal tape is often overlapped in the corners and at the start/stop position. This overlapping of the tape causes significant squeeze-out of edge seal during the lamination process.
