High primary energy savings can be reached for the heating and cooling demand of buildings through a high solar fraction. Both, solar thermal and photovoltaic systems, can be established for these purposes. Concerning the energetic and economic aspects of these technologies a controversial discussion is actually going on. Nevertheless both technologies can be used in solar hybrid systems and are able to achieve advantages within sophisticated hybrid systems.
To serve the energy demand in a sustainable way the target is to develop economic, efficient and reliable solar hybrid systems. In a first step both technologies should be enhanced regarding the economical and energetic efficiency. These potentials have to be utilized before solar hybrid systems are examined. Only when optimized single technologies are used, solar hybrid systems lead to success.
Optimization and development of the solar hybrid system base upon the same methodology. Dynamic simulations are built up, taking into account an extremely minimalized number of components and enhanced schemes. The systems and their control strategies are designed using automated algorithms. The complex minimization problems lead to ideal efficiency. Applying these minimized schemes with combined used components the solar technologies can offer an interesting economic alternative. The performance of this development will be proven in hardware-in-the-loop laboratory measurements.
Finally applicable cost reductions should be shown on system level. The well-grounded, but extensive approach will show the possibilities for both solar technologies, which leads to economical and energetic efficient solar hybrid systems. The promising potential for maximizing the solar fractions will be presented. Thus a reduction of primary energy and greenhouse gas emissions for the heating, cooling and electricity demand can be achieved by using the developed systems.
