Difference be 1-3mm；It should be noted that the protrusion height of the raised line, refers to the raised line as the photic zone where it
The height that 1 table protrudes away from the direction on the surface；The thickness of the battery strings refers to, multiple electricity are being welded by welding
Pond piece 3 is into battery strings and after connecting each battery strings, the thickness of battery strings in the battery component of formation.The protrusion height of raised line with
The difference of the thickness of battery strings is smaller, is advantageous to reduce volume unnecessary in the sealed chamber and wastes, and reduces photovoltaic module
Gross thickness.
The spacing of the two neighboring raised line can also be set to be more than the width of the cell piece 3, it is two neighboring described convex
The spacing of bar and the difference of the width of the cell piece 3 are 3-4mm；From the difference, the spacing of two neighboring raised line is only omited
More than the width of cell piece 3, therefore, two neighboring raised line can limit the displacement of cell piece 3 positioned there between, to battery
Piece 3 plays positioning action, prevents in preparation process is laminated, and cell piece is moved due to that can not position, cause displacement, simultaneously
Piece problem.In addition, when having a raised line between the two neighboring battery strings, the width of the raised line can be set
The spacing being set between less than two battery strings, the difference of the spacing between the width of the raised line and two battery strings
It is worth for 1-2mm.Spacing between two battery strings can be the conventional laying spacing of battery strings in photovoltaic module, can by the difference
See, the edge spacing of raised line and cell piece in battery strings 3 is smaller, can either be by each battery strings even partition, and does not influence electricity
The pond original imposition layout of string, and can battery strings be played with more preferable positioning action.
