Solar World Congress 2025 in Brazil coming up soon
We are excited to invite you to the Solar World Congress 2025 – SWC 2025, which will take place from November 3 to 7, 2025, in the beautiful coastal city of Fortaleza, Brazil. This global congress will bring together hundreds of researchers, students, professionals, police makers, and enthusiasts from all over the world to share knowledge, explore new ideas, and discuss the future of solar and renewable energy. The Solar World Congress 2025 is a truly international gathering where participants can connect with a vibrant community, discover innovative solutions, and take part in inspiring discussions on the energy transition. At the same time, Fortaleza offers an unforgettable backdrop for this exchange of ideas, with its warm hospitality, lively culture, and stunning Atlantic beaches providing the perfect setting for both professional and personal experiences. Whether you are deeply involved in the field of solar energy or simply passionate about building a sustainable future, SWC 2025 welcomes you to join us in Fortaleza for an inspiring and unforgettable congress.

n behalf of ABENS, the Brazilian Solar Energy Association, I warmly invite you to join us at the Solar World Congress in Fortaleza, Brazil. In 2024 Brazil rose to become the fourth-largest solar PV market in the world, adding nearly 19 GW of new capacity, behind only China, the US and India. Our country has vast solar resources and a thriving R&D ecosystem producing high-quality scientific work in solar energy. Fortaleza, with its sunny skies, vibrant culture and breathtaking coastline, is the ideal place to share knowledge, build connections, and celebrate solar energy’s role in Brazil and globally. We look forward to welcoming you!

The scientific program for SWC2025 encompasses the vision of ISES towards 100% renewable energy for all used wisely and efficiently (ISES, 2025). To meet the energy demands with renewable energy supply, system integration solutions that meet sustainability standards is essential, as Figure 1 shows. Renewable energy supplies from solar, wind and other sources, which are predominantly intermittent, are the key focus of SWC2025. Optimal energy demand-side management is central to meet the energy demands of all applications, including e.g. residential, industrial, service, mobility, and agricultural sectors, aiming for both enhanced energy sufficiency and efficiency. To cover the energy demands with particularly intermittent renewable energy supply, flexibility and reliability are the key characteristics sought for, with the aim of enabling energy access for all. Energy policies, markets and social dimensions encompass the drivers and mechanisms to accelerate energy transition to reaching the sustainability goals for socially-just transformation, hence playing an overarching role in SWC2025.
Figure 1. Solar World Congress SWC 2025 Scientific themes (Chiel Boonstra, (SWC 2025, 2025))
The holistic scientific themes in Figure 1 are defined into nine specific scientific themes in SWC2025, namely: 1) Solar thermal power; 2) Solar heating and cooling; 3) PV cell technology and PV systems; 4) Renewable resource assessment and meteorology; 5) Beyond solar: other renewables and associated applications, components, simulation and analysis; 6) Renewable systems applications; 7) Microgrids and grid interaction; 8) Integration of solar energy in architecture and urban planning; and 9) Market, economy, policies, environment and social aspects (SWC 2025, 2025). Each of these themes encompasses multiple sub-themes tailored to the key research and development focuses and questions for solar, wind and other renewable energy sources. Altogether, SWC2025 offers an arena for international experts and stakeholders along the entire value chain, to disseminate, discuss and find robust ways forward in accelerating energy transition for combating climate change, on time!

The general program of SWC 2025 reflects the diversity and urgency of today’s energy transition. Over five days, the congress will offer a rich blend of technical sessions, high-level plenaries, and networking opportunities designed to foster innovation and global collaboration.
Key plenary sessions will feature international experts addressing breakthrough topics such as advances in photovoltaics and solar thermal energy, solar integration in urban planning, the rise of agrivoltaics, and the growing importance of energy resilience in the face of climate extremes. These sessions are designed to connect cutting-edge research with real-world solutions.
Complementing the plenaries, four thematic panels will explore critical dimensions of the global solar agenda: the path to 100% renewables, the role of solar in Latin America, technologies for grid stability, and strategies to overcome energy poverty. These discussions will offer valuable insights and practical strategies for accelerating the clean energy transition.
The program also includes sessions dedicated to young professionals and women in solar, creating space for diverse voices and emerging leadership in the sector. Altogether, SWC 2025 promises to be more than just a scientific congress: it will be a vibrant meeting point for action, dialogue, and transformation in the global energy landscape. We invite you to join us in Fortaleza and help shape a sustainable energy future for all.
