Abstract
The utility model discloses an EPE-isolated solar cell module, comprising a toughened glass layer, a first EVA layer, a battery pack layer, a first bus bar, a second bus bar, a second EVA layer and a backsheet layer which are arranged in a laminated manner, wherein an EPE isolation layer is arranged between the first bus bar and the second bus bar, the EPE isolation layer is used for isolating the bus bars, the EPE isolation layer is formed by laminating a first isolative EVA layer, a PET layer, and a second isolative EVA layer, and the periphery of the EPE-isolated solar cell module is sealed by an aluminum frame. By directly using the EPE materials to isolate the bus bars, the traditional technology of achieving function of isolating active devices by using the backsheet and the EVA materials can be replaced, the assembly production efficiency is improved, and the raw material cost of the assembly is reduced, thus the power generation cost of the whole power plant can be reduced .
Description
Technical field
The utility model relates to a kind of solar module, relates in particular a kind of EPE isolation solar module.
Background technology
Energy and environment are two large basic problems of 21 century facing mankind.Developing pollution-free, reproducible new forms of energy is the only ways that solve this two large problems.At present, photovoltaic generation proportion in the energy is minimum, and high cost is the major obstacle of restriction photovoltaic generation large-scale application.Development of New Generation high efficiency, solar module cheaply approach its cost of electricity-generating even are lower than conventional energy resource, and this has become the problem of the most important thing.
Will use EVA and back veneer material that component bus bar is isolated in the photovoltaic module process of manufacture at present, operating procedure is complicated when placing isolating bar, causes production efficiency to reduce, and increases manufacturing cost.
The utility model content
The utility model purpose: the purpose of this utility model is for the deficiencies in the prior art, and a kind of handled easily, good reliability, EPE isolation solar module that integrated cost is low are provided
Technical scheme: EPE described in the utility model isolates solar module, comprises toughened glass layer, an EVA layer, battery pack layer, the first busbar, the second busbar, the 2nd EVA layer and the backsheet layer of stacked setting; In the battery pack layer, be in series from beginning to end successively by being coated with the tin copper strips between a plurality of cell pieces; Between the first busbar and the second busbar, be provided with the EPE separator, the EPE separator is used for isolation the first busbar and the second busbar, the EPE separator is folded layer by layer and is formed by the first isolation EVA layer, pet layer, the second isolation EVA, is sealed by the aluminium frame around the described EPE isolation solar module.
Further, the backsheet layer arranged outside has terminal box, and the lead-out wire in the described battery pack layer passes EPE separator and backsheet layer and is welded on the binding post of terminal box, then with casting glue with its embedding, can effectively guarantee the reliability of conducting electricity.
Aforesaid EPE separation layer thickness is 0.2～0.4mm.
Beneficial effect: owing to directly use EPE material isolation busbar, replaced traditional use backboard and EVA bi-material just can reach the technology of isolation active device effect, improved assembly production efficiency, reduced the assembly cost of material, arrived and reduce whole power station cost of electricity-generating.
