[0002] The existing solar photovoltaic modules are generally supported by the aluminum rails at the bottom thereof, and the solar photovoltaic modules and the aluminum rails are generally connected by conventional fasteners, which not only has high production costs, but also is inconvenient to install and disassemble, resulting in low assembly efficiency. The fastening structure of the solar photovoltaic module with the application number "CN201120267988.X" includes a solar photovoltaic module and an aluminum rail, characterized in that a clamping block is externally connected to the solar photovoltaic module, and the clamping block is buckled with the aluminum rail. Advantages: The utility model adopts a hook nut for fixing the solar photovoltaic module and buckles with the aluminum rail at the bottom thereof, and no special tools and additional fasteners are needed to connect the two, which effectively improves the disassembly and assembly efficiency and reduces the cost. However, the height of the pressing block is fixed, so that it cannot be adjusted according to the thickness of the photovoltaic panel. When the thickness of the photovoltaic panel is large, the contact between the pressing block and the side of the photovoltaic panel is reduced, thereby reducing the fixing force, resulting in loosening of the photovoltaic panel. Utility Model Content

[0003] The purpose of the utility model is to provide a fastening structure for a solar photovoltaic assembly to solve the problem that the height of the pressing block is fixed and cannot be adjusted according to the thickness of the photovoltaic panel.
