Researchers in Australia say they have found a way to make nano-silicon from recycled solar panels in a way that is highly profitable.

Researchers in Australia find a new reason to recycle solar panels — money!

Recently, we reported on the efforts of SolarCycle, a California startup that is struggling to recycle solar panels and do it profitably. Figuring this out is going to be hugely important as the number of solar panels that are no longer productive increases dramatically over the next several decades.

In 2016, the International Renewable Energy Agency forecast that by the early 2030s, the global quantity of decommissioned PV panels will equal some 4% of the number of installed panels. By the 2050s, the volume of solar panel waste will rise to at least 5 million metric tons a year. China, the world’s biggest producer of solar energy, is expected to have retired a cumulative total of at least 13.5 million metric tons of panels by 2050 — the largest quantity among major solar-producing nations and nearly twice the volume retired in the US by that time.

Solar panels' lifespan is 25-30 years and companies are looking to recycle the valuable, reusable materials and keep panels out of landfills.

As millions of solar panels age out, recyclers hope to cash in

In Odessa, Texas, workers at a startup called SolarCycle unload trucks carrying end-of-life photovoltaic panels freshly picked from commercial solar farms across the United States. They separate the panels from the aluminum frames and electrical boxes, then feed them into machines that detach their glass from the laminated materials that have helped generate electricity from sunlight for about a quarter of a century.

Next, the panels are ground, shredded, and subjected to a patented process that extracts the valuable materials — mostly silver, copper, and crystalline silicon. Those components will be sold, as will the lower-value aluminum and glass, which may even end up in the next generation of solar panels.

Recovered silver, polysilicon, copper, and aluminum from re-hashed panels can fetch the most cash on the recycling market.

Dead solar panels are about to become a lot more valuable

In the coming years, recyclers will hopefully be able to mine billions of dollars worth of materials from discarded solar panels, according to a new analysis published this week. That should ease bottlenecks in the supply chain for solar panels while also making the panels themselves more sustainable.

Right now, most dead solar panels in the US just get shredded or chucked into a landfill. The economics just don’t shake out in recycling’s favor. The value you can squeeze out of a salvaged panel hasn’t been enough to make up for the cost of transporting and recycling it. That’s on track to change, according to the recent analysis by research firm Rystad Energy.
