AI Technical Summary

Technical Problem

Existing mounting systems for solar panels on corrugated steel sheets face challenges due to differential expansion between steel and aluminum components, require custom fabrication, and struggle with force transmission, especially under wind and snow loads, while lacking ergonomic assembly solutions.

Method used

A module mounting system comprising support pieces with fixing screws and module support rails, designed to accommodate differential expansion and transmit forces effectively, using self-tapping threads and adaptable components for various TAN shapes, with clips ensuring secure and ergonomic assembly.

Benefits of technology

The system efficiently manages differential expansion, securely transmits forces, and allows for ergonomic assembly without custom parts, ensuring stable panel mounting on corrugated steel surfaces.

Abstract

A module mounting system (42) for mounting said modules (42) on a surface covered with corrugated metal sheets (TAN), said system comprising: - at least one support piece (4) associated with a fixing screw (16), - at least one module support rail (2). The at least one support piece (4) has a base (8) having a face referred to as the lower face (14) and an opposite face intended to support the head of the fixing screw (16), and a support (12) for the at least one module support rail (2). The module support rail (2) is shaped such that, when mounted on the at least one support piece (4), it has a portion bearing against the support (12) of the at least one support piece (4) and a portion that at least partially overhangs the head of the fixing screw (16).
