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.

Unusual Solar - Renewable and Reused Materials

Mostly, solar panels are made up of nonrenewable, artificially derived components. Virgin plastic, carbon fiber, petrochemical resins. However, can you make a solar panel from renewable and re-purposed materials? We did some tests to find out.

It turns out that the properties that make the plastic good for dog food packaging is very good for the mid-layer in our proprietary SSP panel. And it looks cool.

Certainly, more testing is required to determine the permeability and performance of these materials, but there’s a lot of potential to reduce the embodied energy and environmental footprint of the ingredients to go into solar panels.

Preliminary calculations show that using these materials can reduce the embodied energy (a measure of the overall effort and environmental ingredients that goes into a manufactured product) can be reduced significantly – possibly 25%.
