Solar recycling could lose its silver lining, expert tells inquiry, as case for mandatory fee stacks up - Renew Economy

An expert told an Australian parliamentary inquiry that solar panel recycling is economically unviable without mandatory fees, as the value of recovered materials, including silver, no longer justifies the cost of processing. The recycling industry faces a structural problem: as panel efficiency improves and manufacturing scales, the material content per watt declines, eroding the economic case for end-of-life recovery. The inquiry is examining whether mandatory producer fees should fund recycling to prevent panels from entering landfill.

Where this fits

This is a materials and cost story. Australia's renewable build-out assumes a clean circular economy for solar hardware, but the economics are collapsing faster than policy can respond. A mandatory fee signals that recycling costs were never factored into the headline price per megawatt-hour. The bill, borne by consumers or manufacturers, is a hidden cost of the transition, and it arrives just as deployment scales. Meanwhile, the supply chain for new panels remains dominated by China, which controls both silicon processing and the extraction of minerals like silver, indium and tellurium. Recycling was supposed to reduce that dependency; instead, economics are forcing Australia to choose between landfill and a permanent subsidy.

What it means

Australia is building a renewables grid whose full material and end-of-life costs were not priced in at the start. Each wave of panels installed now will become waste within 25 years, and neither the market nor the grid operator has a funded plan to handle it. The alternative, firm nuclear capacity, produces no panel waste, requires no recycled silver, and depends on a fuel source (uranium) Australia has in abundance and can process domestically. The recycling crisis is not a failure of solar technology; it is evidence that whole-system costing was deferred, and that China's dominance in the supply chain extends to what we throw away.
