Do solar panels need to be edge sealed?

Solar panel manufacturing is complex and challenging. One challenge involves the need to seal the panel against the weather elements to which it will be exposed. The process of edge sealing the panels can make or break the quality of the panel when it is exposed to weather elements.

What is solar panel edge tape (PSET)?

The liquid edge seal is applied in a continuous bead all the way around the perimeter of the solar panel. For solar panel manufacturing, long-term success hinges on developing and perfecting the right process. Shifting from edge tape to pumpable solar panel edge tape (PSET) can improve your manufacturing efficiency and product quality.

Why do solar panels need a pset process?

A reliable trend for solar panel manufacturing, switching to PSET processes has benefitted companies in many ways. The PSET liquid edge seal is applied in a continuous bead all the way around the perimeter of the solar panel.

Why do solar panels need to be sealed?

Simply put, moisture is the enemy of solar panels. Moisture ingress into the panel causes poor performance and premature failure, so properly sealing the panel against moisture is of utmost importance. Because of this importance, much time and effort are spent on this step of the manufacturing process.

What is edge sealing?

Edge sealing using tape has historically been the go-to for manufacturers, who apply the tape manually or with automated equipment. However, inefficiencies in time, material waste, and a lack of dimensional flexibility led to the industry looking to new, more versatile solutions.
