Photovoltaic Module Frame Design to Reduce Light-Blocking Edge Wrap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Photovoltaic modules face efficiency reduction due to frames blocking light-receiving surfaces, which limits the light absorption area and overall performance.
Innovation Solution
A photovoltaic module design featuring a frame with specific portions that are fixedly connected to the back surface of the laminate, allowing for support without obstructing the light-facing surface, and a clamp system for secure mounting on color steel tiles, ensuring efficient solar light absorption and improved structural stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the frame wraps edges of the laminate to protect it and improve structural strength, then the structural strength and protection are improved, but the light-receiving area is reduced and photoelectric conversion efficiency decreases
Solution Approach 1:
The frame structure transitions from a two-dimensional planar wrap-around design to a three-dimensional elevated design. The first portion extends upward from the laminate surface, creating vertical space that prevents the frame from blocking the light-receiving surface while maintaining edge protection functionality.
Solution Approach 2:
The frame is divided into functionally distinct portions: a first portion that extends upward for protection without blocking light, a second portion for clamping connection, and a third portion for additional support. This segmentation allows each portion to optimize its specific function while collectively solving the contradiction between protection and light absorption.
2Object-affected harmful factors
If the frame extends into the frame to wrap edges, then edge protection is improved, but the light-receiving surface is blocked
Solution Approach 1:
The frame's first portion extends in the vertical dimension rather than horizontally wrapping the edges. This vertical extension provides edge protection while maintaining clear horizontal light-receiving surfaces, effectively moving the protective function to a different spatial dimension.
Solution Approach 2:
The elevated first portion of the frame acts as an intermediary protective structure that shields edge positions from mechanical damage while allowing unobstructed light passage to the laminate's light-receiving surface, mediating between protection needs and optical performance.
