Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic module assembly, and particularly relates to a flexible assembly structure for photovoltaic modules. Background Art

[0002] In the existing irregular tile roof structures, the installation of photovoltaic modules faces specific challenges. Due to their fixed shapes and sizes, traditional rigid photovoltaic brackets are difficult to adapt to the roof surfaces with varying curvatures, which limits the application scope and layout flexibility of photovoltaic systems on such roofs. In addition, the installation of rigid brackets usually requires additional fixing measures, such as penetrating the roof materials, which may damage the original waterproof layer, increasing the installation cost and complexity. Flexible photovoltaic panels provide an alternative. They can be directly installed in the grooves between adjacent corrugations of color steel tiles. Such an installation method does not require penetrating the roof, helping to maintain the integrity and waterproof performance of the roof. However, the presence of the irregular shapes of the corrugations forces the flexible photovoltaic panels to be designed into small block shapes that adapt to the groove area, which limits the size of a single photovoltaic module, thus potentially reducing the overall power generation efficiency. And if the flexible photovoltaic panels are directly pasted and fixed on the corrugations, it is not easy to adjust the photovoltaic modules. Summary of the Utility Model
