01 Preparing for the Next Challenge in Solar: End-of-Life Panel
As solar installations from the early FIT-era reach 15–20 years of operation, the industry faces a growing challenge: What happens to solar panels at the end of their lifecycle? While Japan is one of the first markets confronting this issue, the same challenge is approaching Australia, Europe, North America, and other regions where solar capacity is maturing.
02 The Coming Wave of End-of-Life Panels
Government estimates in Japan suggest that by 2030, up to 500,000 tons of solar panels could be generated annually as installations reach the end of their service life. With many early-generation plants entering replacement or decommissioning phases, establishing effective recycling systems has become an urgent industry priority.
03 Challenges Facing the Industry
Despite growing awareness, solar panel recycling in Japan—and globally—is still under development.
Some of the key challenges include:
Immature recycling technologies: Efficient separation and recovery of glass, silicon, and metals remains limited, slowing down sustainable reuse.
Lack of industry collaboration for consistent recycled material quality: Without collaborative frameworks, recovered resources cannot be reliably reused, making circular resource flows difficult.
Risk of improper disposal: Panels are often left unattended or disposed of improperly due to insufficient systems, creating environmental and regulatory risks.
These challenges highlight the importance of industry collaboration and structured recycling frameworks that can be applied worldwide as solar installations mature.
04 GBP’s Contribution to Responsible Recycling
To address these issues, GBP has joined the Solar Panel Reuse and Recycling Association of Japan. Leveraging experience from its O&M and equipment replacement operations, GBP is actively involved in the collection and processing of used panels at the operational level.
Additionally, technical expertise from GBP’s North Ibaraki factory allows the company to provide practical knowledge on panel handling, processing, and recycling. Through the association, GBP shares this know-how to support industry collaboration and the development of structured recycling frameworks, helping build a reliable and sustainable recycling ecosystem.
