ABSTRACT
This paper presents the main part of the results of a research project, done at the chair of electrical power engineering of the University of Hagen / Germany. It could be shown, that it is possible to provide private households self-sufficient with heat and power by the help of a hybridsystem, consisting of a PV-plant linked to a steam engine. This builds a special complex combined heat and power system, which enables a maximum exploitation of primary energy with a highest possible portion of renewable energy. This contribution presents the criterion for the dimensioning of such a system and as a concrete example the data for an average private household in Germany.
