Description

TECHNICAL FIELD

[0001] The application relates to the technical field of photovoltaic installation, and provides a wind-resistant photovoltaic support for standing seam metal roofs. BACKGROUND

[0002] In a photovoltaic system, a photovoltaic support, as an important component of the photovoltaic system, undertakes the task of supporting and fixing photovoltaic modules, and the rationality and stability of the design of the photovoltaic support are related to the operation efficiency and safety of the entire photovoltaic system; in particular, in metal roof applications, the installation stability of the photovoltaic support is particularly important.

[0003] A conventional metal roof structure is usually composed of a plurality of roof panel bodies, and the roof panel bodies are connected through a snap-fit assembly. The snap-fit assembly includes a left extension and a right extension respectively installed on two adjacent roof panel bodies. The snap-fit assembly achieves the close connection between the roof panel bodies through the snap-fit of the left extension and the right extension. When the roof panel body is installed on the roof, the support is clamped between the left extension and the right extension of the snap-fit assembly, and then the support is firmly connected with the purlin of the roof through a bolt or other fastener, thereby completing the installation of the entire metal roof.

[0004] However, in this installation mode, the photovoltaic support is usually arranged at the snap-fit position of the snap-fit assembly. Since the snap-fit position is a key position for connecting the roof panel bodies, the stability of the snap-fit position directly affects the installation stability of the photovoltaic support and even the entire photovoltaic module on the metal roof. In extreme weather conditions such as strong wind and heavy rain, if the connection between the photovoltaic support and the snap-fit position is not stable enough, the photovoltaic module may be detached or damaged, thereby affecting the normal operation and safety of the photovoltaic system. Therefore, a photovoltaic support structure capable of increasing the installation stability of the photovoltaic support at the snap-fit position of the metal roof is needed to effectively prevent the photovoltaic module from being detached or damaged in extreme weather.
