Solar panels: Elastomers and solar coatings solutions ensure reliable production and long service life

Solar panels must work efficiently for decades while withstanding harsh environments. Specialist materials such as our polyurethane (PU) elastomers can be used to achieve this by enabling precision manufacturing. Our coatings also improve the levelized cost of energy (LCOE) for solar panels by decreasing the amount of reflected light and reducing the amount of cleaning effort.

Our Anti-Reflective Coatings for solar glass and Retrofit Coating Service for solar parks boost solar performance worldwide

We expect solar energy to become the standard in energy, and have a bright future. At Covestro we are determined to play a key role in realizing this future through in-depth research and applied technology development to create new Anti-Reflective Coatings and Retrofit Coating Service that continue to extend the product life cycle of solar panels.

Our elastomers ensure reliable production and long operational life

Power Producers need to ensure safe and reliable production of their solar assets. To achieve this, they rely on our high-performance Desmodur® elastomer coating materials which play a key role in the manufacturing of solar panels. The cutting of silicon wafers for solar panel cells is performed with steel or diamond wires guided through pulleys or rollers made with Desmodur® elastomers. These rollers are then robust enough to resist cutting by the wire saw. It also has high tear-resistance and hydrolysis-resistance that translates to a long product lifecycle with low maintenance costs.
