Singapore accelerates solar recycling as PV waste surges and first-generation panels reach end-of-life
Singapore is racing to tackle a rising wave of solar panel waste as early installations age and newer systems replace older, less efficient units. A new automated facility launched by local recycler Redux marks a major step toward building a sustainable, circular solar ecosystem.
Building A Circular Solar Ecosystem
Singapore’s solar deployment has expanded rapidly, with installed capacity rising from 1.193 GWp in 2023 to 1.573 GWp in 2024. With over 1.7 GWp of total installations today, the country is on track to meet its ambition of at least 2 GWp before 2030. But with growth comes a challenge: managing thousands of ageing panels reaching the end of their 20–30-year lifespan.
A New Facility Capable of Processing 36,000 Panels Annually
On Nov 24, Redux launched an automated solar panel recycling facility in Tuas, capable of dismantling and processing 18 panels per hour, or 36,000 panels yearly. This represents about 27% of Singapore’s current PV waste, providing a significant alternative to sending panels to Semakau Landfill — an option that Senior Minister of State for Trade and Industry Low Yen Ling described as “not sustainable” for land-scarce Singapore.
The system can recover up to 96% of materials such as glass, silicon, silver, and metals, reducing landfill load and preventing around 1,400 tonnes of carbon emissions annually.
Why Solar Waste Is Rising Faster Than Expected
According to Redux, decommissioned panels in Singapore will grow from 134,305 units in 2025 to 157,087 by 2030 as first-wave installations fade. Yet some panels are being replaced even earlier — sometimes as soon as year seven — due to faster degradation and a lack of maintenance services locally. Globally, similar panels are maintained for up to 30 years.
This premature replacement contributes to a rising solar disposal market and increases the urgency for proper recycling systems.
Project SolaREV: A Three-Way Collaboration
The new facility is part of Project SolaREV, a collaboration between Redux, EtaVolt, and Vector Green to build Singapore’s first integrated PV waste management ecosystem.
- Redux leads materials recovery, recycling infrastructure, and carbon impact reporting
- EtaVolt, a NTU spin-off, provides engineering expertise and recycling technology
- Vector Green oversees field operations, including decommissioning, collection, and delivery
EtaVolt founder Dr Stanley Wang emphasized the importance of reprocessing materials locally to strengthen the circular economy and reduce the environmental footprint of solar adoption.
Reducing Carbon Impact Through Clean Operations
The solar-powered facility itself uses only 1.14 kWh of electricity per panel processed. Recovered materials are then sent to relevant recycling plants for further refinement, ensuring the process contributes minimally to emissions while extending the life cycle of valuable resources.
A Model For ASEAN’s Renewable Future
Jeff Seah, Founder and Business Development Director of Redux, described SolaREV as an “industry-first system” merging advanced automation with end-to-end accountability. The partnership aims to eventually build a full PV-waste recycling ecosystem for Singapore and potentially set a benchmark for ASEAN, where solar adoption is rapidly accelerating.
This new facility positions Singapore as a regional leader in sustainable solar waste management at a time when both Singaporeans and Indonesians face increasing pressure to balance renewable energy growth with responsible end-of-life practices. As PV installations expand across the SIJORI region, the model pioneered by Redux and its partners could help ensure that the shift to clean energy does not create a new generation of unmanaged waste.
