Dutch Solar Panel Company Solarix Secures €5.5 Million to Transform European Building Facades
Weesp, Friday, 9 January 2026.
Weesp-based Solarix raised €5.5 million in Series A funding to expand aesthetic solar facade panels across Europe. The investment from ROM InWest and VP Capital will automate production and target markets in Germany, Switzerland, and Scandinavia where regulations favor facade solar energy. Founder Marloes van Heteren envisions all new building facades generating energy within years, positioning the company to capitalize on Europe’s growing demand for architecturally integrated renewable solutions.
Strategic Investment Partners Drive European Expansion
The Series A funding round was led by ROM InWest, which has been a long-term investor in Solarix, alongside impact investor VP Capital [1]. Reynier de Monchy, investment manager at ROM InWest, emphasized the strategic nature of this follow-up investment, stating that “Solarix was one of the first parties where ROM InWest invested… This Series A is a very logical continuation for us, with which Solarix can accelerate on crucial fronts” [1]. The funding round involved multiple stakeholders and faced significant time pressure due to subsidy regulations, creating tension in the final phases according to founder Marloes van Heteren [1]. The company also expects substantial subsidies in addition to the €5.5 million raised [1].
Production Automation and Manufacturing Scale-Up
The capital injection will primarily fund the automation of panel assembly at Solarix’s Weesp factory, including robotization and automated production lines [1]. This manufacturing enhancement is crucial for meeting the growing European demand for aesthetic solar facade panels that integrate seamlessly into building architecture [1]. The company has been developing unique coloring technology that allows solar panels to blend with various building designs while maintaining energy generation efficiency [1]. The automation initiative represents a significant step toward industrial-scale production capabilities needed to serve multiple European markets simultaneously.
European Market Penetration Strategy
Solarix is actively working with resellers in Italy, Finland, and Croatia, while pursuing ongoing projects in Germany and Switzerland [1]. Founder Marloes van Heteren highlighted the strategic focus on these markets, explaining that “in countries like Germany, Switzerland and Scandinavia we see stronger market dynamics and favorable regulations to stimulate the development of solar energy on facades” [1]. This contrasts with the Dutch construction market, which van Heteren describes as challenging [1]. The company’s European expansion strategy leverages regions with more supportive regulatory environments for facade-integrated solar technology.
Vision for Energy-Generating Building Facades
Van Heteren articulates an ambitious vision for the future of building design, stating “We expect that all facades in new construction will generate energy in the coming years… Ultimately we want to move toward total energy concepts where the facade is a full-fledged energy carrier” [1]. This perspective positions Solarix at the forefront of a fundamental shift in how buildings interact with energy systems [GPT]. The company plans to scale up and contribute internationally to the energy transition in the coming months [1]. Van Heteren advises other entrepreneurs to “ensure good guidance on legal aspects, but also throughout your entire investment strategy, and stand by your mission, even if the market doesn’t cooperate” [1], reflecting the challenges and opportunities in the rapidly evolving clean technology sector.
