Sollan-Dimsol R&D Project, Solar and Renewable Energy in France Telecom

Since the 70^th, France Telecom R&D has made researches to use solar and renewable energy for powering remote sites. This work includes sizing algorithms, new solutions for battery management, hybrid sources, remote management and several laboratory or field experimentations. The accelerated development of telecom in the world (wireless, broadband access), in a context of environmental concern and energy depletion, induces more researches to optimize remote sites powering and even grid connected solutions. This paper presents a brief history of France telecom involvement, recent research developments results and perspectives
