Abstract
The invention relates to a connection mode of battery pieces in a solar cell module. The battery pieces in the solar cell module are arranged in order in a mode of transverse lines and vertical rows. The positive electrodes of the battery pieces are connected to the positive electrode, while the negative electrodes of the battery pieces are connected to the negative electrode. The positive electrodes of the battery pieces are connected to the positive electrode by connecting the positive electrodes of battery pieces in each line in serial into a cluster and by connecting battery pieces in each row with the positive electrodes of adjacent battery pieces in adjacent rows in parallel into a net. The negative electrodes of the battery pieces is connected to the negative electrode by connecting the negative electrodes of battery pieces in each line in serial into a cluster and by connecting each cluster in parallel. The battery piece organization connected via the connection mode in the invention is used for manufacturing an improved solar cell module. The output generated power of the improved solar cell module is not affected due to shielding or damage of some battery pieces.
Description
Technical field
The invention belongs to solar photoelectric applied technical field, particularly relate to the connected mode of cell piece in a kind of solar module.
Background technology
Current energy supply worldwide enters into epoch in short supply, and a large amount of sustainable new forms of energy, by people's extensive use, importantly utilize solar water heater and solar energy to change into the solar panel of electric energy now.Wherein solar power generation is more and more subject to people's attention, and solar panel is laid on roof, ground etc. and is combined into photovoltaic plant by people.
Conventional solar module cell piece connects as shown in Figure 1 or 2, there is the problem that two have a strong impact on energy output in it: one is because solar panel must be placed in open-air atmosphere, thus always have the objects such as fallen leaves, flying bird, dust to block, these shelters just define shade on solar panel; Two is solar panels under a series of external force impact such as transport, a dead lift, installation, cell piece can be caused to be damaged, hiddenly to split.Above 2 all can be caused energy output to reduce, and affect the output of power.Because common solar panel is generally joined end to end by some cell piece weldings, series connection or series connection combine with in parallel, be encapsulated in a metal framework after lamination, front is that the solar battery cell (cell piece) that silicon chip is made is cascaded, reverse side is that a terminal box is with positive-negative polarity connecting line, several diodes, if once there be a certain cell piece to be blocked or damage, the generating that will affect whole solar panel exports.
The cell piece of crested in one series arm, will be taken as other energy having the cell piece of illumination to produce of load consumption.The solar panel of crested now can generate heat, Here it is hot spot effect.The destruction cell piece that this hot spot energy is serious.Have the portion of energy that the cell piece of illumination produces, the cell piece of all possibility cresteds consumed, and badly influences whole group and generates electricity useful life.In order to prevent cell piece from causing damage due to hot spot effect, a bypass diode in parallel between the both positive and negative polarity of solar panel usually.When assembly has a bypass diode, after a cell piece is blocked by 100%, normal with other cell piece organized with it, then flow through the electric current blocking cell piece and be greater than its photogenerated current, therefore the terminal voltage of this cell piece becomes negative, namely now it becomes load absorbed power, when bearing to a certain extent, bypass diode conducting, bypass there being this group of shade cell piece, avoid hot spot, be not damaged to protect assembly, although this way can have certain protection to solar panel, but bypass the group of shade cell piece, the generated energy of this other cell piece of group will be wasted, thus the generated output that can have influence on monoblock cell panel exports.Also have a kind of possibility, because cell piece group belongs to series connection, if a slice cell piece has part blocked or damage, the generating of this cell piece place group exports and will all can be affected.
Summary of the invention
The present invention is directed to prior art deficiency, propose a kind of connected mode of solar battery sheet, the cell piece tissue adopting this cell piece connected mode to be formed by connecting can be used for prepare can not be blocked because of cell piece wherein or damaged and affect its generated output export battery component.
The present invention solves the technical scheme that its technical problem takes, the connected mode of cell piece in a kind of solar module, the horizontal vertical ordered arrangement in column of embarking on journey of cell piece in described solar module, it is characterized in that, cell piece positive pole is connected with positive pole and cell piece negative pole is connected with negative pole.
As preferably, it is respectively the positive pole of each row cell piece is connected in series bunchiness and each row cell piece is connected in parallel into net with the positive pole of cell piece adjacent in adjacent column cell piece that described cell piece positive pole is connected with positive pole; It is respectively the negative pole of each row cell piece be connected in series bunchiness and each connection in series-parallel be connected that described cell piece negative pole is connected with negative pole.
Innovation of the present invention is the connected mode of cell piece in battery component, and the feature of this connected mode is that positive pole is connected with positive pole, and negative pole is connected with negative pole.Particularly positive pole is connected with positive pole to have employed between each cell piece and not only connects but also netted connected mode in parallel.
The cell piece tissue adopting connected mode of the present invention to be formed by connecting can be used for prepare a kind of follow-on solar module, it can not be blocked because of cell piece wherein or damaged and affect generated output export.That is, when the cell piece in this solar module is when being blocked or damage, be only limited to the cell piece being blocked or damage and do not work generating, and whole assembly generator unit is unaffected, can ensure normal power generation.
The cell piece tissue be formed by connecting by connected mode of the present invention combines with series connection summarizing module, namely can be made into above-mentioned follow-on solar module, but this concrete preparation method, do not belong to task of the present invention, do not repeat them here.
