Gandhinagar: India’s clean energy ambitions are creating a new sustainability challenge. As solar installations continue to expand across the country, experts have warned that solar panel waste could rise to nearly 11 million metric tonnes by 2047, making effective recycling and waste management a critical priority.
Speaking at the GREENS 2026 Summit in Gandhinagar, industry leaders highlighted that while power remains central to India’s energy transition, the sector must prepare for the growing volume of end-of-life solar modules expected over the next two decades.
Solar Panel Waste 2047: Why Recycling Matters
Experts noted that most solar panels have a lifespan of 20–25 years. With large-scale deployment accelerating in recent years, a significant number of panels are expected to reach retirement in the coming decades. Without adequate recycling facilities, the accumulation of discarded panels could pose environmental and resource management challenges.
The discussion also focused on the economic opportunities linked to solar panel recycling. Valuable materials such as glass, aluminum, silicon and silver can be recovered and reused, reducing dependence on fresh raw materials and supporting a circular economy within the renewable  sector.
Industry stakeholders emphasized the need for dedicated recycling infrastructure, clear regulatory guidelines and stronger collaboration between manufacturers, recyclers and policymakers. They argued that planning for waste management should advance alongside renewable energy expansion rather than becoming a concern after the problem emerges.
As India pursues its long-term clean energy targets, experts believe that building a robust recycling ecosystem today will be essential to ensuring that the country’s renewable energy growth remains environmentally sustainable in the decades ahead.
