Solar energy plays an important role in Sweden’s transition to a fossil-free energy system. At the same time, a new stream of products and materials is emerging as more solar panels are installed and eventually taken out of service. CircSolar brought together researchers, companies, and organizations from across the solar panel value chain to explore how Sweden can better preserve the value of panels and materials throughout their life cycle. The project resulted in Sweden’s first circular roadmap for solar panels and six policy recommendations outlining how more functioning panels can remain in use longer, how materials can be recycled at a higher value, and how producer responsibility can work more effectively in practice.
