Solar panel recycling: a future of profitable possibilities

September 15, 2017

Commercial solar panels are creating opportunities for photovoltaic recyclingWith a product designed to produce clean, renewable energy for decades, solar panel recycling probably isn’t the first thing you think about when putting in a new power system. But eventually, someone will need to decide what to do with old solar panels that have slowly degraded over time. And adding to the growing pile of other discarded electronic devices (e-waste) seems an ignoble end for such a green product.

A recent article reprinted by Solar Power World says there’s a better choice that can help the environment while also creating financial benefits. According to the piece, photovoltaic (PV) recycling has the potential to keep an estimated 78 million tons of e-waste out of landfills worldwide while also becoming a $15 billion industry by 2050.

From the article: 

In addition to the monetary value of the material, recycling has the potential to create thousands of jobs for workers involved in the process, as well as new industries focused on utilizing recovered materials.

What are solar panels made of? While there are different types, most panels are primarily comprised of silicon, aluminum and glass. Once separated, these components can be recycled and sold to solar equipment manufacturers. According to a study cited in the article, that could save 10 million tons of retired panels from going into U.S. landfills by the middle of this century.

Also from the article: 

Most solar panels currently in production have a minimum expected lifespan of 30 years, presenting the industry and consumers alike with a major recycling opportunity in the future.

Some members of the solar industry (including SunPower) are already looking ahead by applying a so-called “cradle to cradle” (C2C) approach to their current solar panel production. C2C manufacturing considers the entire lifecycle of a product—from sourcing to end of life repurposing.

While these initial independent steps to address a potentially significant e-waste problem appear promising, the article says policies mandating recycling standards may be more effective. To capitalize on the future benefits, a strategic framework to encourage the practice needs to be established now to set the stage for a solar panel recycling boom later.
