Design of a Size-Flexible Solar Tracker

Abstract

This thesis investigated the design and mechanical analysis of a size-flexible solar tracking system for photovoltaic applications. The aim of the project was to develop a modular and adjustable mechanical structure that can support photovoltaic panels of different sizes while maintaining structural stability, durability, and efficient use of materials. The study focused on the mechanical aspects of the system, including structural design, material selection, and performance evaluation. Control systems and electronic components were outside the scope of this research. The mechanical structure was designed using computer-aided design (CAD) tools, resulting in a modular frame consisting of standardized profiles and custom-designed components. Material selection was carried out by considering mechanical strength, weight, cost, and sustainability. The structural performance of the proposed design was evaluated using finite element method (FEM) analysis under wind and snow load conditions representative of the Finnish climate. The analysis results indicate that the system can withstand the expected environmental loads with acceptable stress levels and limited deformation. The scalability and adaptability of the solar tracking system were also examined, demonstrating its suitability for domestic, commercial, and industrial photovoltaic installations. In addition, the modular design supports easy assembly, transportation, and potential future integration with control and automation systems. Overall, the proposed size-flexible solar tracking system offers a reliable and sustainable mechanical solution for adaptable photovoltaic applications and provides a solid basis for further development in renewable energy technologies.
