Solar energy is a clean and renewable energy source with significant environmental and climate benefits, but it also comes with challenges. 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 or for fully managing all the glass, plastic, aluminum, silicon, silver, copper, lead found in worn-out solar panels. The CircSolar project brings together stakeholders from across the value chain with the goal of proposing a system for sustainable and financially viable management of solar panels.
