Aequitas Carbon is a UK-based investment firm focused on breakthrough energy and materials technologies that support the global energy transition.
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 specialising in, among others, scaling innovative clean-energy and advanced manufacturing businesses.
The firm provides not only capital but also operational expertise to accelerate global growth.
Mark Corbidge, CEO of Abbeydale Partners LLP, adds, “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.
Fund utilisation
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.
This new facility will be a model for HyET Solaris as it expands internationally.
The company 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 adds, “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 €14.5M in venture debt.
HyET Solaris: Develops and manufactures powerfoils
HyET Solaris develops and manufactures Powerfoils, which are ultra-lightweight, flexible solar modules designed for low-cost, large-scale energy generation.
“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 decentralised energy generation and distribution.
