Shape memory alloys, SMA actuator, Sun tracker SMA damper, Fatigue, PV station, commercial building


Integrating PV systems in large commercial areas for electric vehicle charging offers a comprehensive and strategic approach to sustainable business practices. This integration aligns economic, environmental, and social benefits, potentially reducing operational costs and boosting the overall brand image. In the pursuit of improving these types of structures, the use of shape memory alloy (SMA) emerges can be an ideal smart material. These materials can strengthen the structure as a damper and improve energy collection in PV system as mechanical tracker. This study is focused on developing a new smart actuator design that can be used as a sun tracker and mechanical damper in photovoltaic stations for commercial buildings. The proposed SMA actuator can significantly move in response to solar irradiation and can reduce fatigue by stabilizing mechanical stress during bad weather. In order to integrate the proposed actuator with the PV station in response to temperature and stress variation, a mathematical model has been developed. The study seeks to capture the thermo-mechanical behavior, including both superelasticity and the shape memory effect. The findings indicate that incorporating the SMA actuator in the PV station improves energy production efficiency by 19%, decreases vibrations by 85%, and contributes to the station's longevity. These technologies collectively offer environmental, economic, and operational benefits, making it a valuable component in the optimization of solar energy systems
