Are solar panels recyclable?

Compared to other forms of energy production, clean, renewable energy boosts local economies, helps reduce greenhouse gas emissions, and requires virtually no maintenance over the life of the investment. Many industry professionals are unaware of the proper disposal of solar panels after their use.

For an industry that prides itself on sustainability, recycling solar panels at the end of their lifespan is crucial to prevent landfills from overflowing with them. At this point, one might wonder how long solar panels last. Research suggests that glass solar panels have a lifespan of approximately 30 years.

Over the lifespan of a photovoltaic panel, power capacity can decrease by 20%. Efficiency decreases by a maximum of 10% during the first 10 to 12 years, reaching a 20% drop by the 25th year. This has been confirmed by many solar panel manufacturers. However, experience shows that efficiency actually only decreases by 6% to 8% after 25 years. Therefore, the lifespan of solar panels can be much longer than officially stated. High-quality photovoltaic panels can even last up to 30 to 40 years, remaining usable beyond that point, albeit with reduced efficiency.

So, are solar panels recyclable? The answer is yes. Silicon solar photovoltaic panels are primarily composed of glass, aluminum alloy, plastic, and solar cells. These materials are all compostable, but they must be separated beforehand. The following are the main steps for successfully recycling silicon solar panels:

Removing the aluminum frame (100% reusable)

Separating the glass along a conveyor belt (95% reusable)

Heat treatment at 500°C (this allows small plastic components to evaporate, making them easier to separate)

Etching away the silicon wafers and melting them into reusable slabs (85% reusable)
