Solar foils company HyET Solar has secured €60 million in growth capital from UK investors Aequitas Carbon Ltd and Abbeydale Partners LLP. The investment will help build a new 50-megawatt production facility in the Netherlands. The test production is planned for mid-2026, and full commercial output of flexible perovskite PV modules is expected by the end of 2027.
Aequitas Carbon is a UK-based investment firm focused on energy and materials technologies. Maarten Scholten, Operating Partner at Aequitas Carbon Ltd, comments: “HyET Solaris aligns perfectly with our mission to develop affordable, next-generation solar energy solutions. We believe perovskite PV technology will move the industry beyond rigid panels to flexible, scalable formats”. Abbeydale Partners is a UK-based advisory and investment group specializing in, among others, scaling innovative clean-energy and advanced manufacturing businesses. The company provides not only capital but also operational expertise to accelerate global growth. Mark Corbidge, CEO of Abbeydale Partners LLP, said: “This is just the beginning. We see HyET Solaris as the first step toward scaling the broader HyET Group’s transformative technologies across global markets.
HyET Solaris plans to increase its production capacity to 1 gigawatt, with possible expansion in Europe, the Middle East, or both. HyET Solaris continues the legacy of HyET Solar.
Even though a shareholder dispute led to the previous company’s bankruptcy, the main team and their technology remain. By keeping the HyET brand name and look, the company benefits from existing goodwill and a solid reputation.
Co-founder and CEO, Rombout Swanborn, comments: “With Aequitas and Abbeydale, we gain not just capital, but valuable expertise in perovskite PV business and global operations. Together, we can accelerate the global transition to lightweight, affordable solar power.”
The announcement comes over three years after raising €14.5 million in venture debt.
“This is a breakthrough moment for solar energy,” said Edward Hamers, CTO of HyET Solaris.
The Dutch company collaborates with international research institutions to advance clean, accessible solar power worldwide.
The product is made from abundant amorphous silicon, offering an environmentally friendly alternative to traditional solar panels.
The module can be used in various applications, covering a wide span ranging from low-cost utility-scale power plants to integrated high-end architectural solutions.
HyET Solar is part of the HyET Group, which aims to develop technologies that enable commercially viable large-scale implementation of renewable and decentralized energy generation and distribution.
