ES-SO is a not-for-profit organization to Belgian Law (ES-SO vzw) established in Brussels. It is the umbrella organization of the professional solar shading associations in the various Member States of the EU and includes some non-EU members. In countries no professional trade association is in existence, prominent individual companies are invited to join as associate members.

While the solar shading industry in Europe consists typically of small to medium-sized companies, it does employ more than 450,000 people across the 27 Member States and generates annual sales of over € 22 billion (update 2019). ES-SO's location in Brussels means that it is ideally placed to ensure that the industry's voice is heard and that it can make a positive contribution towards the EU meeting its ambitious energy efficiency commitments. ES-SO is also involved in various EU projects and acts in both a contributory and advisory capacity.

Dynamic solar shading can bring 22%  of energy savings and  cut CO2 emissions with 137 Mt/yr in buildings in Europe; see ES-SO study 2015
