Abstract
The invention discloses a junction box for a double-sided battery pack, belonging to the technical field of the solar battery pack. The junction box (6) is a small photovoltaic junction box and connected with bus bars (4) and outgoing lines (7) among each group of double-sided solar battery plates (1), bypass diodes are connected among each group of double-sided solar battery plates (1), and the bypass diodes and the junction box (6) are sealed together by using pouring sealant and fixed in the middle position on the top part of the double-sided battery pack by using transparent silica gel. The junction box can be applied to a double-sided battery pack, has small size, can beautify the battery pack while ensuring the electric performance of the battery pack, and can solve the problem that the conventional photovoltaic junction box blocks the backs of batteries.
Description
Technical field
The present invention relates to a kind of terminal box that is used for two-sided battery component, belong to the solar module technical field.
Background technology
Double-sided solar battery is the positive and negative of battery sheet, under the irradiation of light, can produce corresponding power, thus the power of indirect increase photovoltaic module, the corresponding conversion efficiency of raising monolithic battery sheet.When two-sided battery component is installed on building, under irradiation of sunlight, can utilize daytime the front of assembly that sunlight is converted to electric energy; In evening, the light in the solar cell absorption chamber of reverse side is converted to electric energy.So just increased the power of assembly greatly.
The photovoltaic terminal box is between the solar cell array of solar module formation and the connector between the rechargeable solar battery control device as a vitals of solar module.
Summary of the invention
The object of the present invention is to provide a kind of terminal box that is used for two-sided battery component, can solve the technical problem that conventional photovoltaic junction box blocks cell backside effectively.
The technical solution adopted for the present invention to solve the technical problems is:
The terminal box of two-sided battery component, described terminal box adopts little photovoltaic junction box, and connect every group of busbar and lead-out wire between the double-sided solar battery sheet, be connected with bypass diode between every group of double-sided solar battery sheet, bypass diode and described terminal box one are reinstated the casting glue sealing, and are fixed in the centre position of assembly topmost with transparent silica gel.
Terminal box of the present invention is used for two-sided battery component, and not only volume is small and exquisite, and when guaranteeing the electrical component performance, can also guarantee the attractive in appearance of assembly, has good thermal conductivity, stability and water proof and dust proof performance.
Description of drawings
Fig. 1 is the structural representation that terminal box of the present invention is used in two-sided battery component.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done explanation in further detail.
Two-sided battery component by transparent TPT material, comprise upper strata glass, bottom transparent back panel and middle double-sided solar battery sheet 1, described two-sided battery component comprises 6 groups of double-sided solar battery sheets, every group of double-sided solar battery sheet comprises 12 double-sided solar battery sheets 1, wherein connect with interconnector 3 between each double-sided solar battery sheet 1, be connected to terminal box 6 with busbar 4 and lead-out wire 7 between every group of double-sided solar battery sheet; With EVA laminating seal bonding, aluminium frame 2 was made on assembly refilled after lamination is finished between upper strata glass, bottom transparent back panel and the double-sided solar battery sheet 1; Aluminium frame 2 is doorframe, a window frame industrial aluminum profile commonly used, and terminal box cable 5 is connected with terminal box 6.
Be connected with bypass diode between every group of double-sided solar battery sheet, can effectively prevent the hot spot effect of assembly.Terminal box 6 adopts little photovoltaic junction box, utilizes transparent silica gel to fix, and uses the casting glue sealing, has guaranteed the water proofing property of assembly.
The photovoltaic cell component upper strata glass of present embodiment is set to ultrawhite toughened glass, and is provided with 6 groups, every group and comprises 12 double-sided solar battery sheets 1, totally 72 battery sheets.Double-sided solar battery sheet 1 has been selected positive 17.2% conversion efficiency, and the two-sided monocrystaline silicon solar cell sheet of the back side 12.8% conversion efficiency adopts 72 battery sheets, and the component power that encapsulates is, (at air quality AM1.5, temperature is at 25 ℃, light intensity 1000W/m
2) front is 176W, the back side is 140W, overall power is 316W.And common monocrystalline single face battery component with the battery sheet of this conversion efficiency, can only reach 185W.So compare with the single face assembly, the two-sided power of battery of the present invention has increased 131W.
Claims (1)
1. the terminal box of two-sided battery component, it is characterized in that, described terminal box (6) adopts little photovoltaic junction box, and connect busbar (4) and lead-out wire (7) between every group of double-sided solar battery sheet (1), be connected with bypass diode between every group of double-sided solar battery sheet (1), bypass diode and described terminal box (6) are reinstated the casting glue sealing, and are fixed in the centre position of assembly topmost with transparent silica gel.
