New solar-powered streetlights emerge along Main river
As you stroll along the riverfront in Frankfurt, you might notice a remarkable transformation in the skyline. Thanks to Munich-based studio ttal, led by designers Tobias Trübenbacher and Andreas Lang, an innovative project called Main Light is illuminating the city in new ways. Developed in partnership with Italian lighting manufacturer ewo, this self-sufficient installation shines a light on the future of renewable energy.
Main Light features translucent organic photovoltaic (OPV) solar foils that generate renewable energy directly at the installation site. Unlike traditional lighting systems that rely on extensive underground wiring, these autonomous structures require no permanent ground alterations. This not only minimizes material use but also offers flexible applications for both urban spaces and areas that typically lack resources.
Revolutionizing urban lighting with ecological focus
Driven by the challenges of urban energy consumption and light pollution, Main Light integrates full cut-off technology and demand-based controls. It balances visibility and ecological sensitivity by utilizing warm-spectrum lighting, ensuring minimal disruption to both human and wildlife habitats.
The OPV panels are more than just functional—they visually invigorate the area by casting vibrant, shifting shadows across the riverbank. By day, these panels stand out as interactive elements of the cityscape, engaging passersby with their colorful displays. At night, they provide low-impact yet effective lighting.
Collaborative effort for a sustainable future
This pilot project, realized with ewo GmbH for lighting technology and ASCA GmbH & Co. KG for the photovoltaic systems, positions Main Light not just as an energy solution but as an active contributor to public space. The reversible concrete foundations crafted by Schake GmbH even function as urban furniture, blurring the lines between infrastructure and environment.
The installation takes inspiration from the corporate identity of the upcoming World Design Capital 2026, giving it a visual narrative that can adapt to future projects. Through Main Light, the designers have set a new standard for renewable infrastructure—one that is visible, playful, and deeply embedded in urban life.
Whether you’re interested in cutting-edge renewable technologies or simply seeking a novel public space, Main Light by Tobias Trübenbacher and Andreas Lang offers a compelling vision of what’s possible when design and sustainability merge.
