Solar Centre Symposium 2025: “Transforming Solar Energy Systems: Emerging Technologies and Circular Economy for Sustainability”
The future of solar energy lies in integrating efficiency, circularity, and sustainability from the earliest design stages of technological solutions.
The Solar Centre Symposium 2025, organised by the Solar Centre Twente and the MESA+ Institute, took place on September 12, 2025, at the University of Twente (UT). The event brought together experts from academia, industry, and policy to explore the transformative potential of solar energy systems through a holistic sustainability perspective.
The symposium focused on advancing sustainable strategies for the solar energy sector, addressing technological innovation alongside environmental, economic, and social dimensions. Participants engaged in discussions on the future of solar energy, emphasising the need to move beyond purely technical solutions toward integrated approaches that incorporate circular economy principles and life cycle thinking.
Advancing solar energy systems requires delivering more performance with fewer materials, while addressing environmental, social, and economic dimensions.
Key sessions covered a broad range of topics, including current and emerging solar technologies, the criticality and circularity of raw materials, and sustainability assessment methodologies such as Life Cycle Assessment (LCA) and Social LCA. These discussions highlighted growing concerns about dependence on critical raw materials and the importance of designing modular, recyclable, and material-efficient solar systems.
Sustainable solar energy represents a multidimensional challenge from technological, societal, environmental and economic dimensions.
In addition, the symposium addressed socio-technological and geopolitical challenges, recognising that solar energy technologies are embedded within broader governance and policy frameworks that influence their sustainability outcomes. Economic perspectives further reinforced the importance of jointly considering performance, cost, and sustainability to enable the long-term scalability of solar energy solutions.
A central message emerging from the symposium was that high efficiency, sustainability, and affordability must be pursued together. Achieving a resilient solar energy transition will require delivering more performance with fewer materials, while carefully managing environmental impacts and social implications.
The Solar Centre Symposium 2025 served as a dynamic platform for knowledge exchange and collaboration, strengthening connections between research, industry, and policy, and supporting the development of sustainable, circular, and inclusive solar energy systems.
