Abstract
The utility model discloses a dual -glass photovoltaic assembly, including last glass board, lower glass board, battery piece and EVA, the battery piece is arranged in between two EVA, and two EVA arrange in between glass board and the lower glass board, precoat and be covered with the butyl rubber in the inboard edge of glass board down to form the waterproof banding of confined, EVA's size is less than the size of this waterproof banding. The utility model discloses the subassembly all around with the good butyl rubber of waterproof performance as the banding material, improved the dampproofing and waterproofing performance of subassembly greatly, prolonged service life of assemblies, improved the reliability.
Description
Technical field:
This utility model relates to a kind of double; two glass photovoltaic module.
Background technology:
EVA edge between existing solar double-glass assemblies exposes in atmosphere, and owing to EVA has certain water penetration, therefore steam easily penetrates into assembly from EVA edge, reduces the cell piece life-span, and life-time service causes component power to decline.
Therefore, necessary prior art improves to solve the deficiency of prior art.
Utility model content:
This utility model is to provide a kind of double; two glass photovoltaic module to solve the existence of above-mentioned prior art Problems existing.
The technical scheme that this utility model adopts has: a kind of double; two glass photovoltaic modulies, including upper glass plates, lower glass plate, cell piece and EVA, described cell piece is placed between two EVA, two EVA are placed between upper glass plates and lower glass plate, the inside edge precoating of described lower glass plate is covered with butyl rubber, and form the waterproof edge sealing of closing, the size being smaller in size than this waterproof edge sealing of described EVA.
Further, the thickness of described waterproof edge sealing is 0.5～1mm.
This utility model has the advantages that butyl rubber that this utility model assembly surrounding water resistance is excellent is as edging material, substantially increases the waterproof and dampproof performance of assembly, extends assembly service life, improves reliability. Adopting this kind of precoating lower glass plate, simplify component lamination technique, because butyl rubber and EVA are all thermosol, forming temperature is close, and reciprocal compatibility is good simultaneously, so laminating technology changes without making, simplifies establishment of component technique.
Accompanying drawing illustrates:
Fig. 1 is utility model structure chart.
Fig. 2 is lower glass plate structure chart in this utility model.
Detailed description of the invention:
Below in conjunction with accompanying drawing, this utility model is further described.
Such as Fig. 1 and Fig. 2, a kind of double; two glass photovoltaic modulies, including upper glass plates 1, lower glass plate 2, cell piece 3 and EVA4, cell piece 3 is placed between two EVA4, and two EVA4 are placed between upper glass plates 1 and lower glass plate 2.
In the inside edge of lower glass plate 2, precoating is covered with butyl rubber, and forms the waterproof edge sealing 5 of closing. The thickness of butyl rubber is 0.5～1mm, cooling curing. Butyl rubber is intercept the fabulous a kind of PUR of steam performance, is widely used in building double glazing and automobile and other industries, has excellent durability, it is ensured that the waterproof durability of this utility model assembly simultaneously, is greatly increased assembly service life.
The size being smaller in size than this waterproof edge sealing 5 of the EVA4 in this utility model.Laminated machine hot melt encapsulates, and outer cause water resistance is good, the extraordinary EVA protecting inner side and battery, and butyl rubber is good with lower glass plate 2 adhesive property simultaneously, good endurance.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, can also making some improvement under the premise without departing from this utility model principle, these improvement also should be regarded as protection domain of the present utility model.
