SWC 2021 announced!

We are very pleased to announce that the next International Solar Energy Society (ISES) Solar World Congress (SWC) 2021 will take place at the Pragati Maidan International Congress Centre in New Delhi, India from 24 – 28 October 2021.

New Delhi is the dynamic and vibrant capital city of India, one of the fastest-growing economies in the world and one with ambitious renewable energy development goals. The Indian government recently announced new plans to add 500 GW of renewable energy to its electricity grid by 2030[1]. They have set targets to cut emissions significantly and to have renewable energy account for at least 40% of its installed final energy demand by 2030. India has also set the target of reaching 14 GWth (20-million m2) of solar water heating capacity by 2022.[2]

We are gearing up for this event to be a major platform for the international solar and renewable energy community to meet and exchange ideas. The SWC 2021 will cover a broad range of themes and topics that reflect the unique perspectives of our participants working in solar research and development, industries, governments and academia. The final list of themes will be available when the Call for Participation is launched later this year.

The scope of the SWC 2021 will be multifaceted. The Congress will include technical sessions on a broad range of renewable energy topics, international experts addressing cutting-edge technologies and developments in markets and policies at the governmental, national and regional levels, interactive forums and workshops, strong participation by industry, and numerous networking and social events.

Aapka Swagat Hai – We look forward to welcoming you to the Solar World Congress 2021 in New Delhi, India!


SWC50 - The Century of Solar

SWC50 - The Century of Solar

In 1970 solar research pioneers met at the first International Solar Energy Society (ISES) Conference in Melbourne Australia. ISES is commemorating this Conference with a special 50th Anniversary Virtual Conference, called the Solar World Congress at 50 (SWC50). Please learn more about this new event set-up in the latest SWC50 newsletter here.


The SWC50 highlights the transformation in the global energy sector that has taken place since the first ISES Solar World Congress in 1970 and looks forward to the next 50 years when renewable energy will be the major cornerstone of the global energy system. The Conference will be 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.


The SWC50 will comprise of:

  • A virtual conference in December 2020 which will comprise a total of six 90-minute sessions spread over the 2 days. In the sessions, the presenters will look back over the past 50 years of solar energy development – technical and policy;show the link between the scientists/research and industry; and based on this progress and experience, look forward to what is required within the next 50 years to move towards a global 100% Renewable Energy (RE) target.

The topics for the sessions are:
• Covid-19 and the Energy Transformation: Lessons learnt, and pathways needed to be explored
• Transforming and Growing the Electricity Sector: The Role of Sector Coupling to Meet our End Use Energy Through
• Transforming the Heating and Cooling Sectors: Solar Thermal and Other Technologies to Meet the Heating Requirements of Industry and the Heating and Cooling Requirements of Communities and Buildings
• Transforming the Transport Sector: Sector Coupling, and the Future Roles of Biofuels and Hydrogen/Fuel Cell Technologies
• Garnering Public Support to Achieve the 100% Renewable Energy Transformation
• Enabling a Policy Landscape and the Financial Markets to Achieve 100% Renewables

  • An online display focusing on the stories of solar from the past 50+ years and visions for the next 50 years through the eyes of:
    • Institutions (research laboratories and universities);
    • NGOs and Non-profit organizations:
    • Industry; and
    • Governments.
  • Individuals being recognised in online display through the Renewable Energy Pioneers display;
  • Monthly Newsletters during 2020 and 2021
  • Development of a Commemorative Booklet called The Century of Solar- Stories and Visions of Renewable Energy.
  • A solar time-line display which will be launched at the 2020 Asia Pacific Solar Research Conference (APSRC20) (Nov 30th-Dec 2nd 2020) in Melbourne and will be available to be displayed at future ISES and ISES partner events. (Note: At this stage, the Australia PV Institute (APVI) still plans to hold the regional conference the same week in Melbourne)
  • A historical display at APSRC20.
  • A 50-year celebratory dinner at APSRC20

Institutes, Governments and Industry will be invited to be partners where they can provide their story to the online display and booklet. Individuals will be invited to nominate themselves or others as “renewable energy pioneers”. To celebrate the fact that the first SWC was held in Melbourne, the SWC50 will have a session and celebratory dinner during APSRC20. A historic timeline will be displayed at SWC50 and Platinum, Gold and Silver partners will be listed on banners at the APSRC20

Solar World Congress 2019 in Santiago, Chile

Over 430 participants from 48 countries were welcomed to the ISES Solar World Congress 2019  in Santiago,Chile, held together with the IEA (International Energy Agency) Solar Heating and Cooling Programme (SHC) International Conference on Solar Heating and Cooling for Buildings and Industry.
From 03 - 07 November, the SWC 2019 reinforced the long tradition of connecting the research and academic community with decision makers from different government sectors, industry, financiers and practitioners. This is the first time that the ISES Solar World Congress as well as the SHC Conference took place in South America and we were very pleased to host this event in Chile, a country that’s has shown it's commitment to the fast deployment of renewable energy to transition the Chilean energy matrix to 100% renewable energy.

We thank our host, SERC-Chile (Solar Energy Research Center Chile), a consortium of seven Chilean Universities, as well as the Fraunhofer-Chile Foundation, for their warm hospitality and during the Congress,. Thank you to all our speakers, partners, sponsors and participants for making this event a success.

Solar World Congress 2009 in Johannesburg, South Africa

The ISES Solar World Congress 2009 hosted by the Sustainable Energy Society of Southern Africa in Johannesburg, South Africa, attended by participants from all over the world resolves as follows:

The global target of 100 % renewable energies is both attainable and necessary by the middle of the current century. This is motivated on grounds of ecological, economic and social sustainability.

The unacceptable backlog in energy supply in the third world countries can only be covered cost effectively and in time by the use of renewable energies. Especially the industrialised countries have to increase their efforts in transitioning to renewable energies.
