Design and structural analysis of a small-scale dual-axis solar tracking system based on 3D printing

Abstract

With the increasing demand for renewable energy, solar tracking systems have become one of the most important research topics to improve the efficiency of photovoltaic power generation. However, small-scale solar tracking systems still face significant challenges in achieving a balance between structural simplicity, cost-effectiveness and mechanical reliability. In this study, a two-axis solar tracking system was designed and evaluated under wind load and self-weight conditions through finite element analysis. The simulation results show that the structure has small stress distribution and deformation. It also has sufficient rigidity and bearing capacity to meet the actual application needs. In addition, the proposed design scheme also shows 3D printing and assembly feasibility. The use of ASA material also improves the environmental adaptability of the structure for outdoor applications. This research not only provides practical reference for residential solar energy applications in high-latitude areas, but also provides valuable insights for the future development, optimization and lightweight design of small-scale residential solar tracking systems.
