The Institut für Solartechnik SPF (Institute for Solar Technology) is part of the Hochschule für Technik in Rapperswil (HSR) and employs today a staff of 30 people. Since it's inception in 1981 it has conducted research on and dealt with all aspects of solar thermal energy and associated issues in three distinct departments:
SPF serves technology transfer between research and development centres on one hand and trade and industry on the other. In doing so, SPF acts as a link between users, investors, educational institutions, manufacturers and installers.
The Swiss Federal Office for Energy (BFE) has been a major source of commissions for the Institute since its beginnings. Thanks to long-term research commissions from BFE the institute was able to develop to an internationally recognized centre of expertise.
