Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic modules, and particularly relates to a photovoltaic module. Background Art

[0002] A photovoltaic module, or solar panel, is composed of multiple photovoltaic cell units (usually silicon-based cells) connected in series or parallel. They convert the light energy in sunlight into electrical energy through the photovoltaic effect. By being installed on the top of a building or on the ground, photovoltaic modules can convert sunlight into electricity for household, industrial or commercial use.

[0003] When there is water accumulation on the glass surface of the photovoltaic module, the water accumulation will mix with the outer layer of dust and deposit on the frame of the module. Over time, scale will form on the frame and be difficult to clean. During the operation of the photovoltaic module, the scale will cause the local temperature of the module surface to rise and form a hot spot effect, ultimately affecting the power generation efficiency and service life of the photovoltaic module.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0022] As shown Figures 1 to 6 in the figure, it shows a photovoltaic module provided by an embodiment of the present application, including a solar panel 1 and a fixing frame. The fixing frame includes a diversion frame 21 and a limiting frame. The limiting frame is arranged on the upper and lower sides of the solar panel 1. A positioning groove 221 is arranged inside the limiting frame. A positioning protrusion 11 is arranged on the solar panel 1. The positioning protrusion 11 penetrates into the positioning groove 221 and is embedded and fixed. The width of the positioning protrusion 11 matches the width of the positioning groove 221, and it can just be inserted and has a certain friction force, which is convenient for subsequent fixing work. The diversion frame 21 is arranged on the left and right sides of the solar panel 1. The diversion frame 21 and the limiting frame are connected to each other to fix the solar panel 1. A plurality of diversion grooves 211 are arranged on the diversion frame 21. The diversion grooves 211 are inclined outward. The range of the outward inclination angle of the diversion grooves 211 is 45° to 60°. A diversion channel 212 is connected between the diversion grooves 211. The inclined arrangement of the diversion grooves 211 can make the rainwater on the frame flow into the diversion grooves 211 according to its own gravity, so that less rainwater stays on the edge of the diversion frame 21. At the same time, part of the rainwater flowing into the diversion grooves 211 will flow into the diversion channel 212. The flowing-in of the rainwater can increase the outflow speed of the rainwater, and then drive the rainwater in the next diversion groove 211 and diversion channel 212 to flow out quickly. Such an arrangement can also reduce the situation of rainwater flowing back in the diversion grooves 211, and reduce the stay and accumulation of rainwater.

[0023] In some embodiments, the limiting frame includes a first limiting frame 22 and a second limiting frame 23. The rear end face of the first limiting frame 22 is inclined, and the front end face of the second limiting frame 23 is inclined. The first limiting frame 22 is connected to the upper end of the solar panel 1, and the second limiting connection is connected to the lower end of the solar panel 1. Through such an arrangement, the inflow of rainwater above the first limiting frame 22 can be reduced, and the outflow time of rainwater below the second limiting frame 23 can also be accelerated.

[0024] In some embodiments, first screw holes 213 are arranged on both the upper and lower sides of the diversion frame 21, second screw holes 222 are arranged on both sides of the limiting frame, a connecting piece 3 is connected between the first screw holes 213 and the second screw holes 222, and a bolt 4 is fixed on the connecting piece 3 and is respectively fixed to the first screw holes 213 and the second screw holes 222, which can quickly disassemble and install the module, and the operation is convenient and simple.

[0025] In some embodiments, a waterproof material is applied to the connection between the diversion frame 21 and the limiting frame, such as waterproof glue, etc., to reduce the rainwater from flowing into the gaps of the fixing frame and accumulating.

[0026] In some embodiments, the bottom surface of the diversion groove 211 and the upper surface of the limiting frame are not higher than the upper surface of the solar panel 1. With this arrangement, rainwater can flow out according to gravity, and at the same time, the situation of water accumulation at the edges is reduced.

[0027] In some embodiments, a first diversion protrusion 214 is provided at the upper end of the diversion frame 21, and the first diversion protrusion 214 is inclined upward; a second diversion protrusion 215 is provided at the lower end of the diversion frame 21, and the second diversion protrusion 215 is inclined downward, which can increase the drainage efficiency of rainwater on the diversion frame 21.

[0028] Before use, install it. Align the positioning protrusions 11 of the solar panel 1 with the positioning inserts inside the limiting frame respectively to fix the position of the entire solar panel 1, reduce the probability of misalignment during installation, and make the connection more accurate when the entire assembly is installed. Then fix the diversion frames 21 on both sides to the limiting frame through bolts 4 and connecting pieces 3. Finally, apply waterproof glue at the connection and use it after it dries.

[0029] In the present utility model, through the diversion groove 211 provided on the diversion frame 21, most of the rainwater along the frame flows out obliquely along the diversion groove 211 under the action of gravity. Through the arrangement of the diversion channel 212, the speed of rainwater outflow can be accelerated. With the cooperation of the limiting frame, the time for rainwater to stay on the frame is reduced. At the same time, the entire assembly can be quickly positioned, fixed and installed, with strong flexibility.
