Abstract
It is an object of the invention to disclose a kind of method for reducing solar cell module power loss, compared with prior art, by reducing the solar battery the piece number in battery strings and increasing the quantity of bypass diode, reduce the battery strings number being bypassed as far as possible to guarantee not covered cell piece also normal power generation, the power loss of photovoltaic module is significantly reduced, is achieved the object of the present invention.
Description
Technical field
The present invention relates to a kind of method for reducing power loss, in particular to a kind of reduction solar cell module power damage
The method of consumption.
Background technique
Core component of the solar battery sheet as photovoltaic module, the integrity problem of solar battery sheet are all
Photovoltaic module user and producer's emphasis of interest.And photovoltaic module outdoors prolonged application when be easy to occur because falling on
The blocking of flying bird excrement, dust, fallen leaves etc. causes battery to become energy caused by other photogalvanic cells of load consumption, at this time by
Blocking battery can seriously generate heat, if shelter is not cleaned out for a long time, this fever phenomenon meeting iterative cycles go down, and finally make
Reverse saturation current density increases without limitation and thermoelectricity breakdown occurs.At this point, if after making bypass diode forward conduction, it will screening
A string of cell pieces of gear bypass, and component electric current is flowed through from bypass diode, to guarantee that photovoltaic module works normally, and protect
The cell piece being blocked will not be damaged.Even if in this way, there is no covered battery in the part battery strings being bypassed
Piece also can not normal power generation, be a kind of loss.
But in view of the installation form of the series welding mode of current photovoltaic module and a terminal box, still cause to be bypassed
The cell piece not being blocked in the battery strings fallen can not work normally, and cause the waste of resource.
It is accordingly required in particular to a kind of method for reducing solar cell module power loss, to solve above-mentioned existing presence
The problem of.
Summary of the invention
The purpose of the present invention is to provide a kind of methods for reducing solar cell module power loss, for the prior art
Deficiency, significantly reduce the power loss of photovoltaic module.
Technical problem solved by the invention can be realized using following technical scheme:
A method of reducing solar cell module power loss, which is characterized in that it includes the following steps:
1) in photovoltaic module, the solar battery sheet group of every adjacent two long side is divided into 2 groups, and formed by series welding mode
2 groups of battery strings；
2) in the both ends reverse parallel connection bypass diode of 2 groups of solar battery sheet groups；
3) it reduces the solar battery sheet number in every group of battery strings and increases bypass diode quantity, every piece of solar-electricity
Pond component draws 2 terminal boxes.
In one embodiment of the invention, the photovoltaic module is 60 (6*10) or 72 (6*12) version type photovoltaic groups
Part.
In one embodiment of the invention, the cell piece number of each battery strings is 5 (60 version types) or 6
(72 version types).
In one embodiment of the invention, the bypass diode quantity is 6.
The method of reduction solar cell module power loss of the invention, compared with prior art, by reducing battery
Solar battery the piece number in string and the quantity for increasing bypass diode, reduce as far as possible the battery strings number that is bypassed to
Guarantee not covered cell piece also normal power generation, significantly reduces the power loss of photovoltaic module, realize of the invention
Purpose.
The features of the present invention sees the detailed description of the drawings of the present case and following preferable embodiment and obtains clearly
Solution.
Detailed description of the invention
Fig. 1 is the connection schematic diagram of solar cell module of the invention.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Conjunction is specifically illustrating, and the present invention is further explained.
Embodiment
As shown in Figure 1, the method for reduction solar cell module power loss of the invention, it includes the following steps:

2 groups of battery strings, to reduce the solar battery the piece number in battery strings
2) in the both ends reverse parallel connection bypass diode of 2 groups of solar battery sheet groups, occur in solar battery sheet group anti-
When thermoelectric punch-through, guarantee normal work；
3) it reduces the solar battery sheet number in every group of battery strings and increases bypass diode quantity, every piece of solar-electricity
Pond component draws 2 terminal boxes, reduces the battery strings number being bypassed as far as possible to guarantee not covered cell piece
Also normal power generation.
In the present embodiment, the photovoltaic module is 60 (6*10) or 72 (6*12) version type photovoltaic modulies.
