All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Example 1

Referring to fig. 1-8, the present embodiment provides a lightweight assembly capable of reducing the weight of the whole assembly to a greater extent. The support component 2 is installed on the photovoltaic component 1, and fills the clearance between two adjacent photovoltaic components 1 of installation, and the spring fastener 3 utilizes the structural adhesive to glue four corners at photovoltaic component 1 lower surface to with the mutual detachable joint of support component 2, dismantle, the equipment is more convenient in the bolt fastening, and the colloid frame 4 glues and is used for promoting the leakproofness at light module edge around photovoltaic component 1. The colloid frame 4 is used for replacing an aluminum frame in the prior art, so that the cost can be effectively reduced, and meanwhile, the overall weight of the light assembly is greatly reduced on the basis of improving the tightness. In addition, the outer side and the upper surface of the colloid frame 4 are subjected to ion beam sputtering or chemical treatment, so that the structure and chemical components of the surface of the sealant are changed, the tension and wettability of the surface of the sealant are affected, and the drop-off effect of water drops is improved.

In order to further reduce the weight of the whole lightweight assembly, as shown in fig. 1 and 2, the photovoltaic assembly 1 includes a cell 101 for converting light energy and EVA film 102 mounted on the top and bottom surfaces of the cell 101, a PC panel 103 for reducing the weight of the whole lightweight assembly is mounted on the top surface of one EVA film 102 above, and a glass fiber back plate 104 is mounted on the bottom surface of the other EVA film 102. The upper and lower EVA film 102 are used to encapsulate and protect the battery cells 101, to ensure that the battery cells 101 are not affected by external moisture, dust, dew and other environments, and to prevent the battery cells in the battery cells 101 from being contaminated or damaged by the invasion of external substances. The glass fiber backboard 104 is made of TPT material containing glass fiber, so that certain flexibility is ensured, and meanwhile, structural support, moisture resistance and weather resistance of the photovoltaic module are provided. The PC panel 103 substrate on the upper surface is modified PC, the thickness is 05-1mm, the air surface is plated with a UV coating, the coating thickness is 10-20 mu m, the non-air surface is corona treated, and the thickness of the PC panel 103 is reduced by two thirds relative to the standard thickness of the glass panel, so that the weight of the whole light assembly is further reduced.

Example two

In rainy days, the rainwater on the upper surface of the colloid slides down relatively slowly, the waterproof performance is reduced, in order to improve the water drop sliding rate of the upper surface of the colloid frame 4, as shown in fig. 1-4, the colloid frame 4 is composed of sealing adhesive tapes 401 adhered to the periphery of the photovoltaic module 1 and special-shaped adhesive tapes 402 integrally connected with the sealing adhesive tapes 401, the inclination of the top surface of the special-shaped adhesive tapes 402 is 5-30 degrees, and the inclination in the range can help the water drops on the top surface of the special-shaped adhesive tapes 402 slide down rapidly without staying on the surface. The special-shaped adhesive tape 402 is formed by arranging a plurality of arc-shaped crest portions 4021 and trough portions 4022 at intervals, wherein the crest portions 4021 enable a plurality of water drops to be converged into balls and gradually slide and discharge outwards along the bottom wall of the trough portions 4022 after being aggregated, the vertical distance between the top points of the crest portions 4021 and the center of the bottom wall of the concave position of the trough portions 4022 is 2-5mm, the radian of the side surfaces of the crest portions 4021 is 5-20 degrees, the water drops cannot stay on the inclined side surfaces of the crest portions 4021 for a long time, the water drops easily form balls and slide and aggregate towards the concave positions of the trough portions 4022 on the two sides, and then a large amount of relatively spherical water drops are aggregated at the trough portions 4022 and gradually slide and discharge outwards along the inclined bottom wall. The highest point of the crest portion 4021 is flush with the top surface of the PC panel 103, thereby preventing water drops blocking the upper surface of the PC panel 103 from rolling onto the colloid frame 4. The combination of the plurality of crest portions 4021 and the plurality of trough portions 4022 to form a structure of a suitable depth and height wave shape can more effectively reduce the wettability of the upper surface of the shaped adhesive tape 402 and improve the surface slidability thereof, which is favorable for the water drops to form balls and slide down the inclined walls.

After the battery piece 101 with the EVA adhesive film 102 is arranged in the range of the PC enclosure strip 105, the PC panel 103 is extruded against the butyl adhesive tape 106 on the Ji Bo fiber backboard 104, so that the battery piece 101, the PC panel 103 and the glass fiber backboard 104 are integrated after lamination, gaps between the battery piece 101 and the PC panel 103 can be fully filled and shielded, and then the internal materials of the assembly can be effectively prevented from being corroded by water vapor.
