DOWA ECO-SYSTEM Co., Ltd. (DES) has started a demonstration experiment of a power generation business that utilizes reused PV modules in Fukushima Prefecture, aiming to establish a one-stop service system from PV module removal to reuse and recycling.

Under this project, DES’s subsidiary GEOTECHNOS is responsible for the removal, collection, and transportation of used PV modules. The goal is to ensure safe and efficient handling of end-of-life solar panels while supporting circular economy practices in the renewable energy sector. In addition, Soso Smart Eco-Company, a new venture established with investment from eight companies including DOWA ECO-SYSTEM, plays a key role in evaluating the potential for module reuse. The company inspects used PV modules sourced through multiple procurement channels to determine their suitability for reuse in power generation.

Through this demonstration experiment, DES seeks to build a sustainable business model that reduces waste, maximizes the value of existing solar assets, and promotes resource efficiency in Japan’s growing renewable energy market.
