In both participating project countries (Germany and Poland) it is necessary to further increase the contribution of renewable energies to the energy supply in order to implement both national and European climate protection policy objectives. While Poland's energy supply is currently still largely based on coal, options with lower emissions are to be introduced in the medium and long term. Germany, on the other hand, is pushing ahead with energy system transformation and thus the expansion of a renewable energy supply. The associated conservation of resources and reduction of greenhouse gas emissions should also guarantee a high standard of living for future generations. In order to achieve the necessary goal of a large market share for energy generation technologies on a renewable basis, it is indispensable to be able to offer the available technologies both more cost-effectively and more efficiently.

The goal of the project is the further development and optimization of photovoltaic systems to hybrid high-performance systems, with the help of which the energy of sunlight can be better converted into both usable electrical and thermal energy. In addition, the newly developed system should be easy to control and integrate into the energy supply system of a building. To this end, it is necessary to integrate the technical, ecological and economic parameters of newly designed PV systems into a simulation tool so that the optimum system design can also be calculated for future high-performance PV modules. In addition, the ecological effects of the production, operation and disposal of the hybrid system developed within the project will be evaluated. For example, parameters such as greenhouse gas emissions of the new hybrid plant will be determined and compared with classical solutions for electricity and heat supply. The results obtained will then be integrated into the optimisation tool, so that subsequent plants can also be optimally designed from an ecological point of view.

In order to achieve the overall objective, the following working objectives must be achieved by the German project partners:

  • Development, validation and documentation of a simulation and planning tool for the integration of hybrid systems in building energy supply systems.
  • Determination of environmental impacts and economic parameters of the hybrid system developed in the project
  • Study on ecologically optimal energy supply systems of different building types with or without integrated PV/T system
