Dr. Martin Staffhorst, Founder

Martin Staffhorst is the founder and director of Top50-Solar. Martin has been a passionate advocate of solar energy for many years, and as part of his PhD he worked extensively on the potential for cost-reduction in photovoltaics. Since the mid-90s he was a key supporter of NGOs including the Solar Promotion Association where he served as Deputy Chairman, playing an important role in inventing the Feed-In-Tariff system for Germany. As an expert in photovoltaics he also works as a consultant and is the owner of an engineering company for photovoltaic systems.  Martin’s passion for Top50-Solar was borne from a vision to change our energy systems to 100% renewable energies.
