In addition to regulating the activities and standards of its members, the STA serves as an enquiry centre for the public, industry and governmental bodies. It provides information to enhance the general understanding of the advantages derived from solar energy systems and to encourage potential purchasers to use STA members.

The members are made up of the producers of solar collectors and associated equipment and the installers of systems which cover the solar thermal business in the United Kingdom.

The STA endeavours to influence opinion and facilitate widespread acceptance of all types of solar technology and provides information to its members on a regular basis concerning national and international standards, public enquiries, new legislation and advances in technology. It takes part in standards committees and has a regular dialogue with Government Departments.

The use of solar energy spares the use of conventional fuel and is non-polluting, thus being kind to the environment and reducing running costs for the user at the same time. By choosing a solar energy installation via STA members, you are assured of the highest quality and support.
