Independent power supply is our passion. Our research and innovation team focusses on productive use of energy applications, specifically on solar cooling.
Phaesun GmbH, as a wholesaler and system integrator for PV Off-Grid solutions, has been working in the field of rural electrification, industrial power supply and leisure market applications for more than 20 years. Phaesun headquarters are based in Germany and we can fall back on a partner network in many African countries.
Géraldine Quelle has been working for Phaesun GmbH since 2010 operating research and innovation projects in different African countries, currently coordinating the BeCool Kenya and Ghana project.
