Abstract
The utility model relates to a kind of solar module with high reliability, comprises laminate, aluminum alloy frame and terminal box.Described laminate is installed in aluminum alloy frame, and terminal box is installed on laminate backboard side, and is connected with it by the convergent belt that laminate backboard is drawn.Described terminal box installation site is positioned at backboard top, and the laminate region of its correspondence does not arrange cell piece.The built-in pcb board of terminal box, adopts stamp-mounting-paper diode.This kind of improvement makes terminal box have good thermal diffusivity and stability, the negative effect that the heat avoiding junction box generation brings cell piece, improves the reliability of assembly, ensure that the power stage of assembly, extend the useful life of assembly.
Description
Technical field
The utility model relates to technical field of solar, particularly a kind of solar module with high reliability.
Background technology
Solar energy cleans renewable new forms of energy as one and receives increasing concern in recent years, and its application is also more and more extensive.The main at present two kinds of Land use systems of solar energy are photothermal deformation and opto-electronic conversion, and wherein the principle of opto-electronic conversion utilizes photovoltaic effect that solar energy is directly converted to electric energy.
The core component of solar photovoltaic conversion is solar module, and this assembly is connected by multiple solar battery sheet, and with some special material package become entirety.Because the useful life of photovoltaic generating system design is generally 25 years, so solar module must have stable power stage and good reliability in its useful life, this just proposes very high requirement to the design of solar module and encapsulation.Traditional solar module forms primarily of toughened glass, solar battery sheet, EVA, backboard, aluminum alloy frame and terminal box, wherein terminal box is installed on the back side of assembly, and its major function is transferred to easily in external circuit by the electricity that solar cell produces.In existing assembly, the terminal box back side is solar cell, in the course of work of assembly, components and parts in terminal box can produce heat, due to the limitation of joint-box compound and self structure, its thermal diffusivity is not fine, thus can cause having higher temperature in terminal box, and indirectly causes the temperature of solar battery sheet temperature higher than other cell piece in assembly at the terminal box back side.Decline, so this effect will make the gross output of assembly reduce because solar battery sheet power output raises with temperature; If cell piece and terminal box long-term work are in higher temperature in addition, also larger impact can be produced on its reliability.
Utility model content
For above problem, the purpose of this utility model is to provide a kind of solar module with high reliability, by the improvement to modular construction and terminal box, solve the problems referred to above well, ensure that the power output of assembly and improve reliability and the useful life of assembly.
The utility model is achieved like this, a kind of solar module with high reliability, comprise laminate, aluminum alloy frame and terminal box, laminate is installed in aluminum alloy frame, terminal box is installed on laminate backboard top, and be connected with it by the convergent belt that laminate backboard is drawn, the laminate region that described terminal box installation site is corresponding does not arrange cell piece.
Described laminate convergent belt is connected with terminal box by the mode crimping or weld.
The built-in pcb board of described terminal box, adopts stamp-mounting-paper diode.
Described terminal box enclosure material is aluminium alloy or PPO(polyphenylene oxide) material.
The utility model has the advantage of, device region corresponding to terminal box does not arrange cell piece, therefore the heat that junction box produces can not bring negative impact to cell piece, and can not cause the rising of cell piece temperature, thus the overall power output of assembly is not affected.In addition because terminal box uses pcb board and stamp-mounting-paper diode, its thermal diffusivity is better, and the performance of terminal box is more stable and reliable.This kind of improvement significantly improves the reliability of assembly, ensure that the power stage of assembly, extends the useful life of assembly.
Accompanying drawing explanation
Fig. 1: a kind of solar module schematic rear view with high reliability;
Fig. 2: a kind of solar module front schematic view with high reliability.
In Fig. 1 and Fig. 2,1 is laminate, and 2 is aluminum alloy frame, and 3 is terminal box, and 4 is convergent belt, and 5 is pcb board, and 6 is stamp-mounting-paper diode.
Embodiment
For understanding technical characteristic of the present utility model and content further, be described below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of solar module with high reliability, comprises laminate 1, aluminum alloy frame 2 and terminal box 3.Wherein laminate is with toughened glass, EVA(ethylene-vinyl acetate) and a backboard entirety that solar battery sheet encapsulate, the solar battery sheet exit of series connection passes through convergent belt 4 and draws from backboard side.Terminal box 3 is installed on laminate backboard top, and is connected with it by the convergent belt 4 that backboard is drawn, and the laminate region that described terminal box installation site is corresponding does not arrange cell piece.
Described laminate convergent belt is connected with terminal box by the mode of welding.As preferably, convergent belt uses welding manner to be connected with terminal box.
The built-in pcb board 5 of described terminal box 3, adopts stamp-mounting-paper diode 6.
Described terminal box enclosure material is preferably aluminium alloy, also can adopt PPO material.
Laminate be installed in aluminum alloy frame, between the two by silica gel sealing, aluminum alloy frame machine protects laminate, ensure that the mechanical strength of assembly, facilitates the installation of assembly simultaneously.The convergent belt that terminal box is drawn with backboard is connected, thus realizes component internal circuit and outside connection.
In this embodiment, device region corresponding to terminal box installation site does not arrange cell piece, its objective is the negative effect that the heat avoiding producing in the terminal box course of work completely brings to solar battery sheet in assembly, make the working temperature of cell piece in assembly consistent, the normal power stage of Assurance component.Adopt the terminal box of aluminum alloy casing to make terminal box have better thermal diffusivity, built-in pcb board and stamp-mounting-paper diode substantially increase stability and the reliability of terminal box and assembly.
