Responsible roles / intended readers: Photovoltaic researchers and company representatives; event professionals exploring energy exhibitions and international academic programmes Record / next task: An itinerary of dates, sessions and booths with academic onsite registration or exhibition admission conditions checked Basis of information: The official homepage and exhibition information were checked against the October 29 notice and latest Korean/English Registration Details PDFs, actual visitor-registration page, Daejeon’s August 18 release and IEA PVPS announcement. The latest onsite-registration PDF takes precedence over the webpage’s earlier international USD table. Advance announcements are not reported as completed outcomes. Editorial review: 2026-11-04 A global photovoltaic gathering held every four years In its 18 August press release, Daejeon Metropolitan City described the event as an international gathering held every four years that brings together major photovoltaic conferences from the United States, Europe and Asia. The official website lists the Ministry of Climate, Energy and Environment, Daejeon Metropolitan City and the Korea Photovoltaic Society as hosts. The academic conference runs for six days, while the exhibition is open only from 16 to 19 November, so plan the two parts of your visit around the dates that interest you. Solar & Green-Energy Show: 16–19 November at DCC2 The exhibition runs daily from 10:00 to 18:00 in Halls 1–4 of DCC Exhibition Center 2. Its main fields include solar cells and modules, materials, power conversion systems, photovoltaic mounting structures and installation, and energy storage systems. Hydrogen fuel cells, wind power, smart grids and environmentally friendly mobility will also be introduced. | Event | Schedule | Prepare for your visit | | --- | --- | --- | | WCPEC-9 & GPVC 2026 conference | 15–20 November | Check paid academic registration and the sessions that interest you | | Solar & Green-Energy Show | 16–19 November, 10:00–18:00 | DCC2 Halls 1–4; free admission | | IEA PVPS industry forum presentation | 18 November, 14:50 | Industry forum stage in the exhibition hall | Advance exhibition registration has closed, so exhibition visitors must now register on site.
