Peel Me off the Ceiling

Inter-Layer adhesion is critical to the performance and long term weather ability of solar panels exposed to the harsh environment of sun, rain, wind and abuse. We use an in-house developed peel tester that conforms to the ASTM D903 – 98 (2017) Standard Test Method for Peel or Stripping Strength of Adhesive Bonds.
