How Used Solar Panels Are Powering the Developing World
"In 2016, the International Renewable Energy Agency estimated that as much as 78 million tons of solar-panel waste will be generated by 2050," writes a Bloomberg columnist, adding that that's "almost certainly an undercount..." So what will happen to all those used solar panels? "Across the developing world, homeowners, farmers, and businesses are turning to cheap, secondhand solar to fill power gaps left by governments and utilities," reports Bloomberg. To meet that demand, businesses ranging from individual sellers on Facebook Marketplace to specialized brokerages are getting into the trade. Earlier this month, Marubeni Corp., one of Japan's largest trading houses, announced that it's establishing a blockchain-based market for such panels. Collectively, these businesses will likely play a crucial role in bringing renewable energy to the world's emerging markets — and keeping high-tech waste out of the trash... They may not be good enough for San Francisco homeowners and cutting-edge utilities, but they work perfectly well for anyone in a sunny climate in need of stable, off-grid power who doesn't want to pay full price. That's potentially a huge market. Between 2010 and 2019, the number of people living without electricity declined from 1.2 billion to 759 million worldwide. Some of that gap was closed by new power lines and other transmission facilities. But most of it was achieved by installing small solar systems designed to power a village, farm or even a single home. As of last year, 420 million people got their electricity from off-grid solar systems. By 2030, according to the World Bank, that number could nearly double. A staffer at the used solar equipment exchange EnergyBin said they sometimes have 5 million pieces of photovoltaic equipment on their site. And one broker estimated there were 10 million used solar panels on the global market, saying his own customers included Pakistani farmers pumping water for irrigation and Lebanese hoteliers seeking alternatives to an unreliable local grid.
