Highly it is 4mm~5mm, that is to say, that the interval between the base plate 110 and backboard 200 of foreboard 100 is about 1.5mm~2mm,
So, when the battery strings 310 after being put into cladding carry out the encapsulation of backboard 200 and foreboard 100, backboard 200 has to battery strings 310
There is certain thrust, add the glued membrane and the frictional force between foreboard 100, backboard 200 of the outer cladding of battery strings 310 so that electricity
Pond string 310 can be fixed in the sealing cavity that foreboard 100 is formed with backboard 200 relatively stablely.
In order to the battery strings 310 further to being arranged on foreboard 100 are positioned, can be parallel on base plate 110
Multiple convex tendons are set every ground, battery strings 310 are positioned between adjacent convex tendon, and between convex tendon and margin plate 120 so that electricity
Pond string 310 is effectively fixed.
Certainly, foreboard 100 and backboard 200 are not limited to said structure form, can also be that backboard 200 has base plate and side
Listrium structure, by the inlay card of foreboard 100 in the installation that foreboard 100 and backboard 200 are realized on the ledge structure of the margin plate of backboard 200
Fix, or other can realize the structure that foreboard 100 is fixed with the installation of backboard 200 and makes both form sealing cavity.
The photovoltaic module of the utility model embodiment, assembling process is：
Multiple cell pieces 311 are connected into battery strings 310 via interconnecting strip 312, and battery strings 310 are placed in the first glued membrane
A laminated entirety, the i.e. battery strings 310 of being formed are coated by adhesive film between the adhesive film 322 of layer 321 and second, then by multiple
Battery strings 310 after being wrapped by are connected by convergent belt 313 and form battery component 300, and battery component 300 is positioned over into foreboard
Between 100 and backboard 200, foreboard 100 and backboard 200 seal against each other fixation.
Specifically, being laid on battery component 300 is smooth on the base plate 110 of foreboard 100, then backboard 200 is passed through into step
Structure 121 is installed with foreboard 100 and fixed, and the interface junction of foreboard 100 and backboard 200 is finally sealed using sealant tape, i.e.,
Form photovoltaic module.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
