Tobias Zwirner is the founder and managing director of Phaesun GmbH, a specialist wholesaler and system integrator focusing in Off-Grid power supplies based on renewable energies. Since its foundation in 2001, Phaesun has focused on rural electrification, productive use solutions, solar-powered water pumping systems for drinking water production, water treatment and irrigation of fields, Off-Grid system solutions for industrial applications, the caravan & camping sector, as well as other innovative off-grid power supply solutions. The main target regions are Africa, Latin America, Europe and the Middle East. Phaesun works closely with international NGOs and GOs as well as with local partner companies in the target countries to deliver and permanently establish energy in non-electrified areas.

Gaëtan Masson is an entrepreneur with a passion for solar PV and the energy transition: an engineer, he also has degrees in management, political science and environmental management. He is the founder and Managing Director of the Becquerel Institute since 2014. After a decade in finance and IT, he icommitted to the climate and developed Business Intelligence for SolarPower Europe (formerly EPIA). He coordinates the Task 1, "Expertise and Awareness" of the International Energy Agency PV Programme (IEA PVPS). He led the PV Industry Working Group of the European PV Technology and Innovation Platform (ETIP-PV) of which he was co-chair from 2014 to 2019, and resulted in the creation of the European Solar Manufacturing Council, of which he is co-chair since its foundation in 2019. He is administrator of the CARBON project in France. He participates on the scientific committee of the EU-PVSEC and WCPEC conferences. In Belgium, he is an adminstrator of EDORA, the French-speaking association of renewable energy professionals. In 2020 he received the Daejoo Award for his contribution to the development of photovoltaics.

Ricardo Rüther is a Full Professor at Universidade Federal de Santa Catarina in Florianopolis-Brazil, in the field of solar photovoltaics, solar irradiation resource assessment, electrochemical storage, electromobility, and green hydrogen.
