LSES was formed in April 1980 on the initiative of highly educated engineers and was comprised of solar company owners, chairmen of university engineering departments, along with mechanical and electrical engineers who became the heart of the Lebanese Solar Energy Society LSES. The war in Lebanon between 1975 and 1990 and its economic consequences were a major hindrance to the development of technological studies in manufacturing. In the late 80’s and at the beginning of the 90’s Professor Dr. Sakkal along with Dr. Nisreen Ghaddar built a solar energy laboratory at the American University of Beirut. Moreover Dr. Bassam Ouaida chairman of the Solar Energy Section in the National Council of Scientific Research in Lebanon implemented between 1983 and 1988 a study of weather data together with compiling wind velocity data and an assessment of Solar Energy radiations monitoring in Lebanon. At the end of 2001, the society was reshaped through election of new board members and a restructuring of committees.
