AI Technical Summary

Technical Problem

Traditional vertical installation of photovoltaic solar modules suffers from problems such as easy breakage of module frames, stress concentration, and insufficient wind load resistance. In addition, the installation method has great limitations and cannot meet the stable connection requirements in complex environments.

Method used

The structure combines an upper pressure block and an inner pressure fixture, and is connected by M8 bolts to form a tight fit, ensuring uniform stress on the photovoltaic solar module frame. The C-groove and serrated structure enhance connection stability and provide anti-slip and anti-vibration performance.

Benefits of technology

It achieves stable connection of photovoltaic solar modules when installed vertically, prevents frame deformation and loosening, enhances wind pressure resistance, and improves the overall stability and connection flexibility of the modules.
