Embodiment Construction

[0022] A method for insulating the aluminum backplane of a photovoltaic module, (such as figure 1 , figure 2 , image 3 shown), including the following steps:

[0023] (1) Cutting the aluminum back plate so that the length and width of the aluminum back plate 2 are both 4-5mm smaller than the length and width of the coated tempered glass 1;

[0024] (2) Opening the electrode lead 4 of the aluminum back plate 2 to make it a square opening 3;

[0025] (3) Typesetting and laying of the components (the order is coated tempered glass 1, EVA81, battery sheet 9, EVA82 and aluminum backplane 10, where EVA81 and EVA82 form the EVA layer 8), and insulate the square opening 3;

[0026] (4) Laminate the laminated layers after layout laying;

[0027] (5) Trimming the laminated parts after lamination;

[0028] (6) Use insulating tape 7 to wrap the trimmed laminate;

[0029] (7) Use filled with silica gel 6 (the figure includes silica gel 6 1 、6 2 ) of the aluminum frame 5 on the la...

Abstract

The invention discloses an insulation technology of an aluminum back plate in a photovoltaic module. The insulation technology comprises the following steps: cutting the aluminum back plate, so that the size of the aluminum back plate is 4-5mm less than the size of glass; opening a square opening at an electrode lead part of the aluminum back plate; carrying out insulation treatment on the square opening through cushioning insulation small materials or by adopting a method to cover an edge to the square opening when the modules are arranged and laid; laminating and cutting the edge of a laminated piece; covering an edge to the laminated piece, the edge of which is cut by adopting a 0.5-1mm insulated rubber tape; spraying silica gel on the laminated piece to be framed up; and arranging a connecting box on the laminated piece. The insulation method of the aluminum back plate in the photovoltaic module is convenient to operate, low in investment and wide in application prospect.

Description

technical field [0001] The invention relates to an aluminum backboard insulation technology of a photovoltaic module, which belongs to the field of photovoltaics. Background technique [0002] Heat dissipation and water vapor permeability are important indicators to improve the power output and service life of photovoltaic modules. According to the applicant's knowledge, in the photovoltaic industry at home and abroad, in view of the heat dissipation and water vapor permeability of photovoltaic modules, aluminum backsheet materials with good heat dissipation and water vapor barrier properties tend to be used. However, the insulation of the aluminum backplane is poor, and it is difficult to withstand the high voltage of 6000-8000V, so it is rarely used in crystalline silicon components at present. Contents of the invention [0003] The object of the present invention is to provide a method for insulating the aluminum back plate of a photovoltaic module by using the aluminu...
