The International Solar Energy Society, ISES, works to achieve 100% renewable energy for all, used efficiently and wisely, by providing the global renewable energy community with a collective, scientifically credible voice and up-to-date information gathered and synthesized by its talented members.  

ISES, a non-profit UN-accredited membership NGO founded in 1954, has a long history of being the trusted global advisor on renewable energy and this remains its core value.

ISES informs and connects its extensive, diverse membership of researchers, academics, professionals, practitioners, businesses, decision makers, and advocates in more than 100 countries. 

ISES promotes solar research and development, provides authoritative advice on renewable energy issues worldwide, advocates for a sustainable global solar industry, supports career growth of Young ISES members, and promotes energy education at all levels.  

The ISES Solar World Congress, held biennially since the 1970's embodies the spirit of international networking and exchange of ideas advanced by the Society. Its objective is to maintain communication between the research community, industrial and political players.

SWC50 - The Century of Solar

To celebrate 50 years of ISES Solar World Congresses, ISES started a year long virtual celebration called SWC50 - The Century of Solar in 2020. This celebratory event started with a virtual SWC50 conference and will continue in 2021.

The first ever international ISES Solar World Congress had been held in Melbourne, Australia in 1970 and SWC50 highlights the transformation in the global energy sector that has taken place since then and looks forward to the next 50 years when renewable energy will be the major cornerstone of the global energy system. The Conference is about the people: researchers, industry players, policy makers, and leaders from NGOs and non-profits who have all contributed to make renewable energy the fastest growing contributor to our global energy supply.

On occasion of SWC50, ISES launched a celebratory booklet The Century of Solar - Stories and Visions of Renewable Energy as well as the ISES Solar Energy Museum to celebrate the past 50 years of solar advances.
