The very first solar water heating system installation in Lebanon probably goes back to the seventies of the last century. Few solar water heaters (SWH) were installed in the eighties, yet talking about a "market" for solar water heaters became accurate by the early 1990's. However, SWH's were not on to a successful start. In 2008, only some 25 companies were involved in this market, still in its infancy stage.
