In a striking aerial view captured on January 19, 2026, the Dubbo Solar Hub in New South Wales, Australia, showcases an expansive array of over 30,000 solar panels gracefully spread across 50 hectares of Tom Warren’s farm. This visual epitomizes the rapid transition to renewable energy that Australia has embraced, yet it also casts a shadow on an emerging environmental challenge: the surging tide of solar panel waste.
As Australia stands at the forefront of solar energy adoption, the nation faces an inevitable wave of end-of-life photovoltaic waste, a concern highlighted by Chris Mohen, managing director of Environmental Solar Recycling Australia (ESRA). During discussions with the Senate Standing Committee on Climate Change, Energy, Environment, and Water, Mohen called for a nationwide ban on sending solar panels to landfills. He advocates for manufacturers to shoulder the responsibility of collecting and recycling these panels, ushering in a much-needed shift in industry practices.
The scale of the problem is staggering. Current projections indicate that solar panel waste is poised to escalate from approximately 59,000 tonnes this year to over 91,000 tonnes by 2030, potentially soaring to nearly one million tonnes annually by 2035. Despite the intrinsic value of materials such as glass, aluminum, silicon, and critical metals housed within these panels, a mere 5% is currently recycled. The bulk of this waste finds its way to landfills, is stockpiled, or is sold through informal second-hand markets with minimal oversight, often ending up in regions across Africa and the Middle East.
The paradox lies in the intentions of those involved in the solar energy sector. As Mohen poignantly notes, “On the ground, well-intentioned installers and asset holders are caught between wanting to do the right thing and a system that makes the cheapest option skip bin or landfill.” This highlights a critical issue: the financial incentives often favor the most inexpensive disposal methods, leading to detrimental environmental consequences. Some panels, rather than being responsibly recycled, are either discarded due to low gate fees or stored indefinitely in farms and sheds, awaiting a viable solution.
Interestingly, Mohen points out that a significant portion of discarded panels still holds potential value. Approximately 29% of professionally collected modules could undergo rigorous testing and be repurposed effectively, presenting opportunities for community energy projects, low-income households, remote communities, and innovative agrivoltaic developments. This statistic shines a light on an often-overlooked solution: the second life of solar panels, which can remain functional for 25 to 30 years or more, despite being prematurely decommissioned.
The average age of decommissioned panels is around eight years, yet many are discarded long before they reach the end of their functional lifespan. Mohen emphasizes that these panels still retain their value, suggesting that with the right infrastructure and policies in place, a circular economy in solar panel management is not only feasible but imperative.
In conclusion, the challenge of solar panel waste in Australia presents an opportunity for innovation and responsibility within the renewable energy sector. A nationwide initiative to ban landfill disposal and enforce recycling could not only alleviate environmental burdens but also foster a sustainable industry that recognizes the value in every solar panel. By shifting the narrative from waste to resource, Australia can lead by example in the global shift toward a circular economy, ensuring that the benefits of solar energy extend far beyond the production phase and into a sustainable future.
