Solar energy is a clean and renewable energy source, but are the solar panels themselves sustainable? Unfortunately, not entirely. Solar panels have a lifespan of about 30 years – with significant potential for repair, reuse, upgrade, and recycling. However, there is currently no circular system in place, neither for reuse nor for fully managing all the glass, plastic, aluminum, silicon, silver, copper, lead found in worn-out solar panels. The CircSolar project gathers stakeholders from the entire value chain with the goal of proposing a sustainable and financially viable system for the circular management of solar panels.
