With this project in Norway, Swiss solar roofing provider Sunstyle has shown how photovoltaics can be adapted for sensitive heritage sites. The listed church in Sarpsborg is now equipped with discreet, roof-integrated solar shingles. Such approaches are key to expanding solar use across more rooftops, especially those in open and unshaded locations.

Solar modules fitted
Because conventional rooftop PV systems are too visually intrusive, they are at risk of being rejected by monument protection authorities. In such cases, solar modules must be fitted into the roof cladding so they are not visible. However, the surface itself must remain unobtrusive and integrated. In addition, the fragile construction of many historic roofs can limit the use of standard systems.
Preserving the architecture
The church in Sarpsborg, with its high glass windows, was built in the neo-Gothic style and is a landmark in Norway’s third-oldest town. After a fire in 1861, it was reconstructed on the original foundation walls and has since undergone several renovations, all without compromising its distinctive architecture.

Solar roof tiles are almost invisible
The most recent renovation continued that tradition. Rather than standard roof tiles, the town opted for solar shingles from Sunstyle. With their flush profile, the tiles blend seamlessly into the roof, thus preserving the church’s historic character while generating clean electricity.

Raising money for renovations
Solar energy can offer more than just environmental benefits for historic buildings. By reducing energy costs or even generating revenue, PV systems can support ongoing maintenance and conservation efforts. In this way, solar technology becomes a tool not only for climate action, but for protecting cultural heritage. (su/tf)
