The effective implementation of a PVT system
Summary
This thesis investigates the effective implementation of photovoltaic-thermal (PVT) systems in various building types to optimize energy use and reduce carbon dioxide (CO2) emissions, aligning with global efforts to combat climate change. Conducted at Smits van Burgst, a medium-sized engineering firm in the Netherlands, this research responds to the increasing demand for sustainable building solutions. Although Smits van Burgst has extensive knowledge of installation technologies, its understanding of PVT systems remains underdeveloped. Therefore, this study aims to expand the company’s capabilities in designing and implementing these systems effectively.
PVT systems combine the functions of photovoltaic (PV) panels and solar thermal collectors, allowing for the generation of both electricity and heat from a single installation. This dual functionality optimizes the use of available roof space and contributes to the reduction of a building's carbon footprint. While research has demonstrated that PVT systems are both efficient and cost-effective, there is still a need to explore their integration with other technologies to enhance performance and suitability for different building types.
To address these objectives, a MATLAB Simulink model was developed to simulate the performance of PVT systems across various building types, including office buildings, hospitals, medium-sized houses, and supermarkets. The model analyzed the electricity generation and demand, comparing these across different scenarios to identify when and where PVT systems are most effective. The findings were supplemented with an extensive literature review aimed at identifying complementary technologies that could further optimize PVT system performance.
The results indicate that office buildings can best use either smart EV charging stations or heat pumps to utilize excess energy. Conversely, residential buildings and supermarkets find greater benefit by combining PVT systems with long-term energy storage solutions, such as heat pumps with thermal energy storage systems or thermochemical storage systems. It is recommended for hospitals to not make use of additional technologies, as there is rarely any excess electricity to be utilized.
Based on the simulations and literature review, this thesis provides practical recommendations for implementing PVT systems in different contexts, emphasizing the importance of tailored solutions to maximize efficiency and sustainability. It also highlights the need for further research to refine these strategies, including the development of more comprehensive models that incorporate additional technologies. The insights gained from this research contribute to the advancement of sustainable building practices, supporting efforts to reduce carbon emissions and promote energy efficiency in the built environment.
