Australia’s clean energy surge is powering homes and reshaping skylines with solar projects and modern construction — but behind the progress lies a growing waste challenge, as aluminium scrap and discarded solar panels continue to pile up.
Each year, an estimated 4 million solar panels are removed from rooftops across the country, yet less than 5 per cent are recycled according to The Smart Energy Council (SEC). Without urgent intervention, experts warn solar waste could nearly double in the next five years — from 59,340 tonnes in 2025 to 91,165 tonnes by 2030.
Solar panels are taken down due to malfunctions, performance drops, or early upgrades, while fragile roofs and safety regulations further contribute, often resulting in panels being removed well before their expected lifespan.
One irony of the federal battery rebate scheme is that while it accelerates clean energy adoption, many households are seizing the opportunity to upgrade their rooftop solar. In most cases, that means replacing smaller systems with bigger, more modern ones — sending perfectly functional panels into landfill or storage.
