The ISES Solar World Congress 2025 (SWC 2025) is organized jointly by the International Solar Energy Society (ISES) and its Brazilian section, the Brazilian Solar Energy Association (ABENS), the congress is a key platform for advancing solar science and technology.

Brazil's Leadership in Renewables

Brazil's selection as the host city highlights its significant achievements in renewable energy. The nation's energy matrix is notably clean, with almost 50% of its overall consumption coming from renewable sources. This figure rises to over 85% for electricity, powered by a mix of hydropower, biomass, wind, and solar energy. These efforts have earned Brazil a prominent global position, ranking 3rd in installed renewable power capacity and 4th in the global PV market in 2022. The congress will leverage this impressive domestic landscape to showcase Brazil's commitment to a sustainable energy future.

Key Themes and Strategic Timing

The congress will feature a comprehensive program, including presentations by distinguished keynote speakers, technical sessions, and networking opportunities for professionals and researchers. The event's themes are diverse, covering critical topics such as:

• Solar thermal power and solar heating and cooling
• PV cell technology and systems
• Microgrids and grid interaction
• Market, economy, and policies
• Integration of solar energy in architecture and urban planning

Notably, the timing of SWC 2025 is highly strategic, as it will occur just weeks before COP30 takes place in Brazil. This provides a crucial stage for researchers worldwide to present their latest findings and will help to set the agenda for these vital global negotiations on climate and energy.
