What is a polyurethane composite solar panel frame?

The polyurethane composite solar panel frame developed by Covestro and its partners has demonstrated excellent material performance. As a non-metal material, polyurethane composite frames also reduce the overall price and increase energy efficiency for solar panel module manufacturers over traditional metal aluminum frames.

Is BASF's new polyurethane-based PV module frame sustainable?

Aiming towards a more sustainable plastic use in future BASF and Worldlight’s new polyurethane-based PV module frame is the newest addition in the industry. With better efficiency, the new frame offers huge reductions in emissions as compared to aluminum frames.

What is Covestro polyurethane coating?

Covestro has developed the two component waterborne polyurethane coating technology for its PU composite frames to protect solar panel frames that are exposed in outdoor environments for years. The major binders in the formulation are Bayhydrol A and Bayhydur series products.

Is Covestro Pu composite a good choice for photovoltaic modules?

Photovoltaic module systems with Covestro’s PU composite frames have been certified by TÜV Rheinland in 2021, showing that this new material can meet the stringent requirements of the renewable energy sector while providing a low-carbon emission, high-quality solution to development needs.

What are the advantages of Pu composite solar panels?

The volume resistivity of PU composites can reach 1×10 14 Ω-cm. If a solar PV module is packaged with a non-metal frame, the possibility of forming a leakage circuit is greatly reduced, helping reduce occurrences of Potential-Induced Degradation (PID) .The harm of the PID effect results in power attenuation and a decrease in power generation.
