Loci: The Integrated Solar Roof for Aesthetically Responsible Architecture

If you are in the Netherlands, Belgium, Germany, the Gulf region, the Caribbean, Southern Europe or parts of Africa and seeking the ultimate blend of sustainability and aesthetics, Loci is the innovative, patented solution. It seamlessly integrates roofing and energy generation via solar panels. Turn roofs into powerful energy hubs with sleek, modern appeal—ideal for both new construction and renovation projects.

How does Loci preserve the aesthetic integrity of my design?

• Discreet & elegant: The panel size is smaller than traditional panels, enabling subtler integration.
• Timeless appearance: Deep matte black panels that harmonize with many architectural styles.
• Seamless finish: The system is fully roof-filling—from ridge to gutter, façade to façade.
• Flexible edge detailing: Choose from HPL cladding color combinations for a clean, personalized finish.
• Watch a project video (De Woonschakel Westfriesland) for visual inspiration.

What design freedom and functionality does the Loci system offer?

• Preserves integrity: Functional panels without compromising the aesthetic vision.
• Flexible roof forms: Any pitched shape is achievable, with solutions for dormers and exhaust flues.
• Lighter structure: At about 24 kg/m² complete, it allows for a lighter roof design, which may lead to significant savings in construction materials and costs.
• Microgrid potential: In sun-rich regions such as the Gulf, Caribbean, Southern Europe and parts of Africa, combining the Loci system with battery storage can support neighborhood-wide off-grid microgrids. This drastically reduces infrastructure dependency and grid connection costs while increasing energy independence.
• Complies with standards: Helps demonstrably meet energy performance requirements (Beng registered).
• Value through sustainability: An innovative, sustainable solution that enhances property value.
