Covestro in Solar: Retrofit Anti-Reflective Coating Service

Improve your solar park energy conversion efficiency with a power boost of up to 3% – and payback time of less than three years – with our acclaimed Anti-Reflective (AR) Coating. We can now retrofit your modules with this technology, fast, and cost efficiently.

Today, our AR Coating is used in some 300 million photovoltaics (PV) modules (totaling 100GWp) worldwide – and counting. By covering the surface of the solar glass, this patented technology prevents more sunlight from being reflected away – delivering a potential 3% solar efficiency gain in the field.   

Now, we can retrofit this AR Coating for older PV modules in existing solar parks – without you having to replace the panels. Our experienced technical team simply sprays the coating onto your solar panels at a rate of around 10,000 panels per day. And that is it.

Proven solar power boosting technology

Our Retrofit AR Coating has already been extensively piloted by several well-known industry players. 
One of Europe’s largest PV park owners, Enerparc, recently unveiled the results of a two-year pilot program with this technology – and they are now set to extend this even further. The Covestro Retrofit AR Coating achieved a power gain of between 2-3% across some eight different power plants in Germany and Italy. 
Meanwhile, the solar asset management specialist WiseEnergy  has benefited from a 2-3% power gain in the field at one of the Italian solar parks it operates. “Covestro came in and applied their AR Coating very fast and efficiently on the existing solar panels,” said Diego Molina, Innovation Manager at WiseEnergy. “This was key because we need to balance the value of potential increased performance with the cost of installation.” 
The bottom line: this technology can improve the performance of older solar parks today by unlocking additional value, boosting internal rate of return (IRR) – and achieving payback time within three years.

Better together in solar

There is no innovation without collaboration, which is why at Covestro we are always looking for new partners. Our network of collaborators helps develop, test and launch solar solutions into the marketplace faster – whether it is leading institutes like Fraunhofer or CPVT, or the young innovators of tomorrow taking part in our SunRISE Challenge.  
The list of our partners is long, but some of the key ones include: Flat Glass Group, Wuxi Suntech, Fraunhofer ISE, CPVT, Greentown Labs and Apricum, as well as research partnerships with Technical Universities of Delft and Eindhoven, and Oxford University.

Here is a brief flavor of the work we are doing.
