About SOLARSTONE

VISION: Building the future of roofing - where every roof produces energy.

Our mission

We want to make solar integrated roofs the new normal in roofing materials...

SOLARSTONE develops and manufactures integrated solar roofs that combine energy production, durability, and architectural integrity. Our products have proven them selves in the Nordic climate and have been installed on thousands of roofs across Europe. At SOLARSTONE, we believe that solar roofs are the new normal and using solar energy doesn't have to be a compromise made at the expense of architecture – ROOF. DESIGN. POWER.

Why SOLARSTONE?

How we are building this change

Roofing, redefined

Building-integrated PV (BIPV) transforms the role of the roof. Instead of simply protecting the building, it becomes an active part of it — generating clean energy while maintaining a seamless architectural appearance. With SOLARSTONE's solar roof, energy production is built directly into your home, making solar a natural part of everyday living.

Europe's leading BIPV production facility

Our production enables solar roofs to be delivered at scale. Instead of one-off projects, systems are manufactured with consistent quality and precision, ensuring reliable supply for both new-build and renovation markets. With integrated processes and growing capacity, solar roofing becomes a practical, repeatable solution for increasing demand across modern construction.

System, not product

SOLARSTONE is not just a PV-panel - it's a complete roofing system. Structure, waterproofing, and energy production are designed to work together from the start.

Partners network

We don't just sell - we build a network and develop ecosystem. Trained roofers and partners ensure consistent quality, scalability, and local presence.

Designed to last

Roofing is a decades-long decision. Our roofs are built to match that lifespan combining durable roofing performance with long-term energy generation you can rely on.

A SOLARSTONE story

A project manager, engineer, and a roofer look at a house

SOLARSTONE was founded in early 2015 by a group of friends who were facing technical challenges while working on various real estate projects. Back then the energy crisis and sustainability challenges were not yet making any headlines. Only a few were anticipating the green transition to become a real thing. Our idea was to create durable and smart roofing systems that would also alleviate dependence from the energy grid.
While concrete and clay tile roofing systems were known for their durability in contrasting climates and solar technology was becoming more available and commonplace, it still did not offer a wide choice of rooftop applications.

Innovation in solar roofing and clean energy solutions. Solarstone.

We embarked on a journey with a goal to develop an all-round PV module compatible with a variety of roof tiles seamlessly matching contemporary architecture. Beauty and functionality became one. Solar Tiled Roof was born.
By early 2024, we've grown to 50 people and secured a foothold in 10 markets. Our portfolio has grown and our universal BIPV solutions are making a difference in the building industry. Our patented and award-winning Solar Full Roof technology unlocks possibilities unimaginable before with unlimited domestic and commercial applications.

Our purpose

Solarstone is a proptech company with an impact. We provide solar roofing solutions people actually need by replacing outdated roofing concepts with sustainable and cost-effective multi-purpose technology, helping everyone become energy prosumers.
