HyET Solaris is an Amsterdam-based company focused on producing ultra-lightweight, flexible solar foils that can be rolled out on surfaces where standard glass solar panels are impractical. The technology is designed to lower installation costs and open new markets by enabling solar deployment on rooftops and structures with limited load-bearing capacity. With its latest financing, the company intends to build a dedicated flexible solar foil manufacturing plant in the Netherlands to scale commercial production. The plant is expected to advance the mass-manufacturing of its solar foils, boosting European supply of lightweight photovoltaic materials. Investor interest, reflected in the sizeable growth capital round, underscores confidence in the firm’s technology and expansion plans.
