EuroSun Conferences

Established by ISES in 1996, the EuroSun conferences take place every two years in cities all across Europe.

At EuroSun conferences we provide a global forum for scientists, researchers, engineers, architects, and representatives from industry and business to present and discuss their latest findings, developments and perspectives. The conferences give you a chance to present your work, meet researchers, developers, and industry and government representatives, and send you home inspired and motivated to continue moving the world towards 100% renewable energy.

Since 2022, the EuroSun conferences are jointly organized by ISES and the IEA SHC Solar Heating and Cooling Programme (IEA SHC).

Interested in hosting a EuroSun conference? Submit your expression of interest to the next EuroSun call for proposals which will be launched two years in advance of the next conference.

EuroSun 2024 : 26-30 August 2024 in Limassol (Cyprus)

ISES and the IEA Solar Heating and Cooling Programme are pleased to announce EuroSun 2024 - the ISES and IEA SHC International Conference on Sustainable and Solar Energy for Buildings and Industry - to take place from 26 - 30 August 2024 in Limassol, Cyprus.

EuroSun 2024 is jointly organized by ISES and IEA SHC and the local hosts are the Cyprus University of Technology and the local ISES section, ISES Cyprus.

At EuroSun 2024, we are looking forward to welcoming solar researchers, experts, industry representatives, students, and practitioners from Europe and all around the world. The programme will feature dedicated technical sessions on the congress themes, high-level keynotes by expert speakers, workshops, a technical tour and more. Since the first EuroSun Conference took place in 1996, the conference has become one of the main events on solar energy for buildings and industry in Europe. The role of PV, solar cooling, storage and grid integration is especially crucial for isolated sunny islands like Cyprus, and the organizers are especially pleased to offer a full programme and dedicated networking opportunities with senior experts from research and


EuroSun 2024 will cover a broad range of solar themes:

  • Energy Efficient Buildings
  • Sustainable heating and cooling systems for buildings
  • Solar and Efficient Districts
  • Sustainable Process Heat for Industry
  • Sustainable Energy Infrastructure and Electrification
  • Thermal energy storage
  • Solar Thermal and PVT Collectors and Solar Loop Components
  • Solar Air Conditioning and Refrigeration
  • Sustainable and Solar Energy Transition
  • Solar Resources and Energy Meteorology

EuroSun 2022

EuroSun 2022 took place from 25 - 29 September 2022 in Kassel, Germany.

Organized by the International Solar Energy Society and the IEA Solar Heating and Cooling Programme and hosted by the De­part­ment of So­lar and Sys­tems En­gi­nee­ring at the University of Kassel, this first in-person EuroSun conference since the COVID-pandemic welcomed 486 attendees from 54 countries all around the world.

Throughout the four conference days, attendees joined 5 plenary sessions, 10 keynotes, oral sessions across 20 conference themes, three poster sessions, workshops, technical sessions, and more.

In 2022, a special focus of the organizers was to support young scientists and students, and a wide range of events for these young attendees was offered such as the Masters Course in Solar Energy including free accommodation, free conference attendees for 75 students, a dedicated networking session for junior scientists and senior experts and much more.

The conference was made possible by the generous support from public supporters such as the German Federal Ministry for Economic Affairs and Climate Action, the University of Kassel and the state energy agency of Hesse as well as by the conference Gold Sponsor Viessmann and the Supporting Sponsors Enersolve, Qconcept, Stadtwerke Kassel and the cdw foundation.

EuroSun 2020

13th International Conference on Solar Energy for Buildings and Industry

01 - 03 September 2020 - Virtual Conference


EuroSun 2020 - it's a wrap!

Over 200 hundred attendees from countries all around the world attended the first-ever virtual EuroSun 2020 and the three conference days were packed with state of the art scientific presentations on the conference's 13 conference topics, networking sessions, workshops and more.

EuroSun 2020 offered a platform to discuss the latest developments with leading solar energy experts as well as policymakers and industry representatives. The programme included distinguished keynote speakers in plenary sessions, specialists meetings in breakout sessions and poster exhibitions as well as social events with the opportunity to network, meet old friends and to make new ones.

The Conference was organized by ISES in cooperation with the Cyprus University of Technology, the University of West Attica and supported by the IEA Solar Heating and Cooling Programme.

Thank you to everybody who attended EuroSun 2020!

EuroSun 2018

12th International Conference on Solar Energy for Buildings and Industry

10. - 13. September, 2018
Rapperswil, Switzerland

Event Homepage:

This years welcoming message:
It is our great pleasure to invite you to EuroSun 2018 in Rapperswil, Switzerland.
This year’s conference will be held on the beautiful campus of the HSR University of Applied Science Rapperswil on Lake Zürich.

The worldwide success of renewable energy technologies, and solar energy in particular, is remarkable, and it is what we all work for. In many cases solar technologies are already the most economical way to produce electricity or heat. But there is still a very long way to go to achieve the goal of a 100% renewable energy supply. Efficiencies must improve and the costs of components and services must be reduced further. We need a shift to thinking in terms of systems and a better understanding of the interaction of the electricity, heat and mobility sectors.

In the last few years we have seen a growing competition between solar thermal technologies and solar electricity in the heating sector. It is not yet clear where that competition will lead us. Most certainly our future energy system will have a higher grade of electrification. On the other hand it seems likely that energy systems will be more stable and more efficient if a variety of technologies complement each other.
The EuroSun conferences focus on Solar Energy for Buildings and Industry, covering both, heat and electricity.

We are pleased to announce that the EuroSun 2018 will be organized in cooperation with the Swissolar Solar Heating Conference, the 2nd SIGES Conference on the Simulation of Energy Systems for Buildings and the 8th International Conference on Solar Air Conditioning.

EuroSun 2018 will offer a platform to discuss the latest developments with leading solar energy experts as well as policy makers and industry representatives. The programme will include distinguished keynote speakers in plenary sessions, specialists meetings in breakout sessions and poster exhibitions as well as social events where you will have the opportunity to network, meet old friends and to make new ones.

For three days the campus of HSR in Rapperswil will host the “who ‘s who” in solar energy for buildings and industry. We look forward to welcoming you there for EuroSun 2018.

Aix-Les-Bains, France

Solar energy and solar buildings are fundamental pillars to achieving a transition to a renewable energy society. While Europe is 6 years from 2020 when the binding targets of the 3x20 will be evaluated, technologies under development today should be common place in this horizon.

To bring light to the latest developments, the scientific and organizing committees invited scientists, engineerings and policy makers to Aix les Bains, France to participate in EuroSun 2014, a European solar energy conference, organized jointly by ISES Europe and INES.

The conference proceedings are available in the ISES Conference Proceedings Database.
