DGS Federal Association

German Society for Solar Energy

Founded in 1975, the “Deutsche Gesellschaft für Sonnenenergie” (DGS) is the oldest solar association in Germany. Since 1989, DGS has been known as the German Section of the International Solar Energy Society (ISES). DGS is a registered non-profit organisation with approximately 2,800 members, making DGS the strongest independent solar association in Germany.

The main aim is to achieve an entire energy supply based on renewable energies in Germany by 2050.

To achieve this goal, the DGS supports the introduction of new sustainable energy conversion techniques and energy-saving technologies as well as promotes environmental and climate protection.

Consequently, a major aspect of the work is education and disseminating information about renewable energies. The implemen­tation of new results into technical applications and thereby into everyday life is an important part of the work of DGS. DGS considers itself to be a mediator between scientists, engineers, architects, craftsmen, the building industry, public authorities, politicians and the government.

DGS is an accepted consumer protection organisation according to §22 of the AGBG (Germany Civil Code). The DGS represents the interests of consumers in the fields of renewable energies and the efficient use of energy sources.
