In the course of the nationwide support programme, BeBa Energie enters the professional installation of solar systems on building roofs in 1999 as one of the first electrical companies in Schleswig-Holstein. The 100,000 Roofs Program is a further development of the 1,000 Roofs Program from the early 1990s. Under the 100,000 Roofs Programme, photovoltaic systems installed by private individuals, freelancers and medium-sized companies are subsidised within the framework of the Renewable Energy Sources Act. By the time the subsidy volume is reached in 2003, more than 300 megawatts of installed capacity will have been created in Germany.
