Abstract
The Austrian "Klima- und Energiefonds" started 2010 a funding program for the development and further market
penetration of large-scale solar thermal systems. The most interesting projects in terms of innovation were selected
for a system monitoring, analysis and optimization of about 12 months by a scientific partner. Since 2010 about
25 combined solar thermal and compression heat pump systems (STHP systems) were selected within this
framework and for eleven of these systems monitoring data is available. In this paper the selected systems are
categorized and findings from the monitored systems are presented. Therefore, the performance of the systems is
assessed with technical, economic and ecological parameters. In principle, the compression heat pump suits well
to the solar thermal system to generate low temperature heat for space heating purposes and hot water preparation.
The compression heat pump acts flexible and generates heat whenever the solar energy is not available. STHP
systems show also a very positive effect for reductions of environmental impacts. But lack of standards for
planning and realization leads to higher effort, higher risk and costs. Up to now the knowledge transfer by the
scientific partners to the market players is essential for the further development of this technology.
