Covestro Shanghai Installs PU Composite PV Frames

Shanghai, China - Covestro has recently introduced a distributed photovoltaic power generation facility at its Shanghai integrated production site. The facility has utilized the company's own PU composites.

At the Shanghai site, an impressive 30,000 m2 of PV modules were successfully installed on rooftops, car parks, and unused areas. The company anticipates generating an additional 6 million kWh/year for on-site consumption, in addition to the 0.5kWh/year already produced by the existing PVs at the site. Projected carbon emission savings are estimated to be around 5000 tones.

Through a collaboration with Zhejiang Deyilong, the PV module's PU composite frames were crafted using Baydur PU resin. The company highlighted the excellent anti-corrosion performance of these products, which is especially crucial for areas with high humidity and salt spray.

“Integrating this new PV power generation facility represents another stride towards emission reduction and achieving full circularity for our site,” said Yun Chen, the site’s general manager. “While the solar power it generates contributes only a fraction to our site’s power consumption, the message is clear: we are committed to aligning all our activities with circular principles and want to contribute to the circular economy with the materials we produce.”

Because they are not made of metal, PU composite frames make panels more efficient at making electricity by lowering the damage caused by voltage. In addition, their carbon footprint is significantly reduced compared to the more common aluminum frames due to a less energy-intensive production process.
