Integration and operation strategies for PVT in Swedish apartment buildings
PVT (photovoltaic and thermal technology) is an interesting alternative to mitigate the seasonal imbalance between solar energy and heating demand in Sweden, while increasing the efficiency and lifetime of solar cells. The goal of this project is to develop strategies for how a PVT system should be integrated with the other energy systems used in multi-apartment buildings and to critically evaluate the performance of the entire system and compare it with a corresponding system with pure PV.
This project will investigate synergies between PVT and geothermal storage and potential "hidden" long-term benefits of such hybrid systems. New installation and operation strategies for PVT in combination with geothermal storage will be developed, tested and evaluated using life cycle methods to increase our knowledge and understanding of their cost-effectiveness and contribution to sustainability over the lifetime of the systems. Two new integration scenarios will be developed and tested in real buildings to evaluate proposed system configurations. Using field studies in real buildings, the project will experimentally compare PVT systems with pure PV and scientifically validate models and simulations developed in the project. This project will also develop decision-making data and guidelines for sizing and installing PVT systems in existing/traditional energy systems in multi-apartment buildings.
The project is financed by SBUF.
