Peter F. Varadi co-founded Solarex Corporation, USA, in 1973 to develop the utilization of solar cells for terrestrial applications. Solarex was one of the two companies that pioneered this field. By 1983, it became the largest PV Company in the world, when it was sold to AMOCO. Dr. Varadi continued consulting for the European Commission, World Bank, NREL, and other organizations. His book Sun above the Horizon, which describes the meteoric rise of the solar industry, and its sequel, Sun towards High Noon, were published in 2014 and 2017, respectively.

Frank Wouters has been leading renewable energy transactions and technology development for over 28 years. He developed projects valued at over $5 billion, ranging from small-scale PV solar electrification in Uganda to a strategic equity investment in the world's largest offshore wind project in the UK. Mr. Wouters has served on the boards of several energy companies in Europe, USA, Africa, and Asia and currently is director of the EU GCC Clean Energy Network. Previously, he was deputy director-general of the International Renewable Energy Agency (IRENA).
