Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panel installation, in particular to a solar photovoltaic panel installation fixture. Background Art

[0002] Solar photovoltaic panels are devices that can convert light energy into electrical energy. They have attracted much attention due to their environmental protection, renewable nature, and not being affected by fuel price fluctuations. Before putting solar photovoltaic panels into use, it is necessary to select a suitable installation location, and then use a mounting fixture to fix the installation. During the fixed installation, the orientation and tilt angle of the photovoltaic panel must be adjusted according to the location, so as to improve the power generation efficiency of the photovoltaic panel.

[0003] China Invention Announcement No.: CN116582065B includes a base, a fixing mechanism and a wiping mechanism. In the present invention, the U-shaped plate is stacked with the fixing plate, and the orientation and angle of the placement plate are adjusted. Then, the U-shaped plate is fixed by the cooperation between the first fixing groove and the mounting hole and the first bolt. Finally, the photovoltaic panel is installed on the corresponding placement plate. The placement plate is fixed and installed by a single bolt. At the same time, the angle and orientation of the placement plate are adjusted, and the vertical plate drives the corresponding placement cylinder to clamp and limit the placement axis. At the same time, the supporting plate on the rack plate has a supporting effect on the corresponding placement plate, and the overall operation steps of installing and fixing the front and rear placement plates are simple and easy to operate, reducing the overall construction time and construction cost.

[0004] The applicant found that the patent had some shortcomings in use: the device uses the traction of the pull rope to move the wiping plate to wipe the photovoltaic panel, but the pull rope will block the photovoltaic panel, and there will be shadows after the sun shines. Due to the existence of local shadows, the current and voltage of some battery cells in the solar cell module have changed, resulting in an increase in the product of the local current and voltage of the solar cell module, thereby generating local temperature rise on these battery modules. At this time, the shaded part of the series branch will be treated as a load, consuming the energy generated by other unshaded solar cells. Therefore, the shaded part will generate heat at this time. This is the hot spot effect. The appearance of hot spots will affect the use of photovoltaic panels. Common photovoltaic shadow blocking sources include wires, surrounding plants, etc., and the device also has the function of cutting plants under photovoltaic panels. The taller the plants grow, the higher they are, and they will block the photovoltaic panels when they are higher than the photovoltaic panels, which will also affect the use of the photovoltaic panels.
