Fraunhofer ISE researchers, in addition to partners of institutes in Stuttgart and Hameln, will follow the performance of a maximum of nine PVT systems in apartment buildings, companies, offices and industrial buildings for several years as part of a project that builds the case for a broader implementation of technology.
Researchers from the Fraunhofer Institute for Solar Energy Systems (Fraunhofer Isee) of Germany are working on a project that promotes the use of photovoltaic-thermal (PVT) collectors and heat pumps in the construction sector.
The Integrate-XL project is a collaboration between Fraunhofer Isee And its partners at the University of Stuttgart’s Institut für GebäudeenerGetik, Thermotechnik und Energenspeicherung and the Institut Für Solarennergiefchung in Hameln.
The four-year project, which started in December, is intended to further improve the combination of PVT gatherers and heat pumps in large apartment buildings and commercial properties. A statement about the project says that these technologies are now “technically and economically attractive for the delivery of thermal and electrical energy supply and therefore have to be determined” in existing large -scale buildings.
A maximum of nine PVT systems, deployed in apartment buildings, companies, office buildings and other branch buildings will be investigated over several years.
The research team will collect and compare measurement data with analysis of previous planning and simulation work, culminating in an evaluation with possible improvements in efficiency and grid in supplyability. Measures for operational optimization will also be developed in collaboration with system operators.
A statement from Fraunhofer ISE says that the findings of the commissioning and operation of the systems will be made available as a knowledge base for future installations. In the meantime, technical and economic findings will go to the design of political framework conditions, such as financing schemes.
The Fraunhofer statement also estimates that the implementation of PVT systems on 5% of all newly renovated apartment buildings can achieve a total saving of approximately 560 million tons of CO2 in the coming 25 years.
PVT collectors combine solar modules with solar energy collectors, making the production of electricity and heat possible at the same time.
An international group of scientists published in October research On eight different types of PVT systems to understand how design influences the efficiency of module.
