In addition, the terminal box of existing solar module all is mounted in the head position of solar module, and the more system's installation cost that causes of mounting bracket required when using on the solar cell power station is than higher.
Summary of the invention
The objective of the invention is to address the above problem, make solar cell can access better protection and cost can significantly not improve, and can reduce system series resistance, improve the power output of solar module.
For this reason, the invention provides a kind of solar module, it is made up of two loops, and described two loops lay respectively at the both sides of described solar module, and conflux respectively to terminal box in described two loops, described terminal box is positioned at the middle part of described solar module.
As preferably, described two loops comprise at least one and branch road that form in parallel with diode by a plurality of solar cells respectively.
As preferably, branch road that form confluxes to a terminal box at least one of described two loops respectively by a plurality of solar cells are in parallel with diode.
As preferably, branch road that form confluxes to same terminal box relative two in the position in described two loops by a plurality of solar cells are in parallel with diode.
As preferably, each described branch road comprises 9-14 sheet solar cell.
As preferably, each described branch road comprises 10-12 sheet solar cell.
As preferably, described two loops comprise 3 and branch roads of forming in parallel with diode by a plurality of battery components respectively, respectively conflux to 3 described terminal boxes in described two loops.
By solar module of the present invention, can guarantee bypass diode and solar cell in the solar module effectively, can Yin Wendu not too high and assembly is damaged, and can reduce the series resistance of solar module integral body, especially can significantly reduce series resistance and system's installation cost of the system of solar module composition of the present invention.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is carried out clear, complete description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belongs to the scope of protection of the invention.
Fig. 3 is the circuit diagram of an embodiment of solar module provided by the invention, Fig. 4 is the schematic diagram of an embodiment of solar module provided by the invention, as shown in Figures 3 and 4, the solar module 6 of present embodiment is made up of two loops, two loops lay respectively at the both sides of solar module, and conflux respectively to terminal box 1 in two loops, terminal box 1 is positioned at the middle part of solar module.
The solar module of forming with 72 solar cells is an example, among this embodiment, the solar module 6 that will comprise 72 solar cells is divided into two sub-solar modules 61,62 by 36 solar cell series connection, and two loops are in the inner not connection of solar module, promptly do not electrically connect in solar module 6 inside between two sub-solar modules 61,62, conflux respectively to terminal box 1 in two loops, comprise two bypass diodes 5 independent of each other in each terminal box 1, in parallel with the sub-solar module 61,62 of both sides respectively.Though be three terminal boxes in the accompanying drawing, and two bypass diodes are arranged in each terminal box, two of each terminal box tandems are respectively from the corresponding branch road in the position in two loops, but accompanying drawing only is an example, not as a limitation of the invention, also can be each branch road difference tandem to a terminal box or the common tandem to of the wherein several branch roads terminal box in two loops.Like this, solar module 6 is divided into two independently sub-solar modules 61,62 in inside, and two sub-solar modules 61,62 conflux respectively to the mode of the terminal box 1 that is positioned at solar module 6 middle parts, make the length of busbar 3 to shorten, reduce series resistance, improve the whole output performance of solar module.
Be 200910137269.3 at application number, denomination of invention is in the patent application of " solar battery module frame, solar module and installation system thereof ", the technical scheme that the frame that utilizes architecture advances and mounting rail are installed solar module is disclosed, it can be so that solar module uses installation section bar still less when mounted, and it is fast, convenient, efficient, time saving and energy saving.The terminal box 1 of the solar module of present embodiment is positioned at the medium position of solar module, and can cooperate above-mentioned application number well is the solar module installation system of 200910137269.3 patent application.From Fig. 5 and Fig. 2, as can be seen, can shorten the length of the cable that connects between the solar module like this, thereby reduce the resistance of the system of solar module formation, improve the output performance of system and the cost of reduction system.
In another embodiment of the present invention, above-mentioned sub-solar module 61,62 (that is, two loops) comprises at least one branch road, and each a plurality of solar cell of route and diode are formed in parallel, and wherein, each branch road can comprise 9-14 sheet solar cell.Preferably, each branch road can comprise 10-12 sheet solar cell, can connect by the lead (busbar) of solar module inside between the branch road.Solar module with 72 solar cells is an example, each sub-solar module 61,62 all can comprise 3 branch roads, wherein each branch road can be formed in parallel by 12 solar cells 4 and bypass diode 5, conflux to 3 terminal boxes 1 that are arranged in the solar module medium position through busbar 3 then, diode 5 in terminal box, outgoing cable 2 from terminal box 1 again.Solar module with 60 solar cells is an example, each sub-solar module 61,62 all can comprise 3 branch roads, wherein each branch road can be formed in parallel by 10 solar cells 4 and bypass diode 5, conflux to 3 terminal boxes 1 that are arranged in the solar module medium position, outgoing cable 2 from terminal box 1 again through busbar 3 then.Comprise two bypass diodes 5 independent of each other in each above-mentioned terminal box 1, in parallel with each branch road of both sides respectively.
Like this, because series connection solar cell quantity reduces, with 12 solar cells is example, the reverse voltage of 12 solar cells is about 7V, therefore when solar module generation hot spot effect, after even bypass diode is breakdown, it is too high and burnt that solar cell is unlikely to Yin Wendu in the time of also can guaranteeing hot spot effect takes place, and (solar cell of Irev＜2A/-8V) can not go wrong yet even performance is relatively poor relatively at present.And from Fig. 5 and Fig. 2 as can be seen, can shorten the length of the cable that connects between the solar module like this, thereby reduce the resistance of the system that solar module constitutes, improve the output performance of system and reduce the cost of system.
In a word, the above is embodiments of the invention only, is not to be used to limit protection scope of the present invention, but is used to illustrate the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
