Solar Roofs for Historic Buildings

Imagine a world where every rooftop could harness the power of the sun even those atop our most treasured, centuries-old buildings. Thanks to advances in solar technology, this is no longer just a dream.

At SunStyle, we believe heritage and innovation can go hand in hand. Our building-integrated photovoltaic (BIPV) systems make it possible to generate clean energy without compromising the architectural integrity of historically significant buildings.

When renovating heritage buildings, respecting their original design is key. Standard solar panels often clash with these aesthetics and can even be rejected by preservation authorities due to their bulk and appearance.

SunStyle solar roof tiles offer a discreet alternative. With their sleek, tile-like form, they seamlessly integrate into rooftops even on structures with historical or cultural value. And because our tiles are lightweight, they’re a safer option for fragile or aging rooftops.

To assess solar potential, urban planners and architects now use advanced 3D modeling based on publicly available satellite imagery. These tools map out roof surfaces and identify optimal locations for PV installation even across entire towns or heritage zones.

This technology accelerates decision-making and helps ensure that renovations, especially for protected buildings, are handled with precision and care.

One remarkable example lies in the city of Sarpsborg, Norway. The neo-Gothic church at its center is a symbol of the city’s identity with soaring glass windows and a storied history dating back to its reconstruction in 1861 after a devastating fire.

When the roof was renovated in 2019, Sarpsborg made a bold choice: preserving history while embracing the future. SunStyle’s solar roof tiles were chosen for their flat, architectural look and ability to blend into the historic character of the building all while generating renewable energy for the community.

Historic buildings often have expansive, underutilized rooftops an opportunity for clean energy that shouldn’t be overlooked. Yet many such buildings rely on public funds, foundations, or municipalities for maintenance, without expecting financial returns.

By integrating solar energy into these renovation projects, decision-makers can unlock new funding sources, lower energy costs, and reduce carbon emissions all while preserving cultural heritage.

Projects like Sarpsborg are more than technical achievements. They are visible proof that it’s possible to combine tradition and sustainability. They inspire communities, inform policymakers, and set a precedent for future renovations whether for churches, castles, or old townhouses.

Another noteworthy example is the Löwenscheune in Grosshöchstetten, Switzerland, a centuries-old barn structure listed as a protected historic building. During its recent renovation, maintaining the authentic appearance of the roof was non-negotiable. Thanks to SunStyle’s integrated solar tiles, the project achieved both heritage preservation and energy efficiency. The discreet design of the tiles complemented the traditional architecture, enabling a seamless blend of old and new. Today, the Löwenscheune not only stands as a cultural landmark but also contributes to the energy transition, proving that even the most delicate buildings can embrace solar innovation without compromise.

SunStyle is proud to be part of this movement.
