Inaventa Solar has developed the BI70 solar collector where metals have been replaced with polymers. The use of polymers is said to make the collectors more cost-effective, while also introducing a greater degree of flexibility and resulting in higher environmental values.
Most solar collectors are still made out of metals, produced individually and in fixed sizes. By switching to polymer materials – the production process becomes more efficient, while also enables a higher degree of customisation. Polymer collectors are also more lightweight than their metal counterparts, and are therefore easer to transport and handle at the construction site.
The BI70 solar collector uses Solvay’s Ryton PPS1 to replace metal. The product therefore benefits from long-term heat resistance up to 160°C and excellent hydrolytic resistance. Its resulting light weight means the solar panels save energy even before they are installed, and make life easer for installers. The polymer also helps architects achieve a more seamless and aesthetic integration of the solar collectors into the roofs and façades of buildings.
“The main reason for replacing metals with polymers in our business is linked to the goal of making solar collectors with a lower carbon footprint,” explains John Rekstad, CEO of Inaventa Solar. “The smooth and efficient collaboration with Solvay has resulted in a material solution that meets all key design and manufacturing requirements of our new solar collector.”
