Description
Technical field
The invention belongs to photovoltaic technology field, in particular to the electrical connection methods of a kind of solar module and use should
The solar module of method.
Background technique
Photovoltaic module efficiency is higher and higher at present, and the space for further increasing component efficiency is smaller and smaller.However due to too
Positive energy battery is not a perfect current source, while being also a load, how in the case where not increasing cost, is reduced
The loss of battery itself, improving fan-out capability just seems increasingly important.The loss of solar cell itself is by way of heat
The heat for losing, while generating can also react on battery, reduce battery efficiency.Therefore the calorific value for reducing battery is one
The very well approach of raising efficiency.Due to P=I2* R, so reducing the electric current that inside battery flows through can be effectively reduced hair
Heat.
Currently, the effective ways for reducing internal current are segmentation batteries, reduce monoblock battery area, therefore half battery is answered
It transports and gives birth to.When reducing cell area reduces electric current, voltage is constant, and solar module is by muti-piece solar battery string
It is formed after connection one voltage class appropriate of acquisition, after being divided into half, all concatenated component voltages will be promoted
One times.It if being divided into two block assemblies, and will lead to steeply rising for packaging cost, even more than pass through improved efficiency bring
Cost decline.For this purpose, the top and the bottom by half component universal in industry are respectively connected later again in solar module
Middle part is together in parallel, as shown in Figure 1.However the program can significantly increase the area of solar module, lead to the wave in space
Take, this is away from each other with lifting assembly efficiency.
Summary of the invention
It is an object of the invention to: in view of the above problems, providing one kind both can solve high-efficiency battery component voltage
The matching problem of electric current and photovoltaic generating system back segment equipment, and the solar module for going here and there and connecting freedom degree can be improved
Electrical connection methods and the solar module for using this method.
The technical scheme of the present invention is realized as follows: a kind of electrical connection methods of solar module, the sun
Battery component includes the solar cell piece of several arrays, it is characterised in that: firstly, each solar cell piece is divided at least two
Solar module is integrally divided into and divides equally the consistent at least two parts of the piece number with solar cell piece, then, by solar cell by piece
All scribing batteries in the every part of component are all cascaded, and an independent outlet is formed on solar module
End, finally, can be freely series-parallel between every part of adjacent solar cell component.
A kind of solar module using above-mentioned electrical connection methods, the solar cell piece including several arrays are special
Sign is: each solar cell piece is divided at least two panels, and the solar module is integrally divided into and solar cell piece
Respectively consistent at least two parts of the piece number, all scribing batteries in the every part of solar module are all connected on one
Rise, and form an independent leading-out terminal on solar module, on the solar module quantity of leading-out terminal with too
The positive divided quantity of battery component is consistent.
Solar module of the present invention, each solar cell piece are divided into two panels and form half battery,
The solar module is integrally divided into two parts, and all half batteries in the every part of solar module are all connected
Together, and in the end of solar module leading-out terminal is formed.
Solar module of the present invention, the solar module are divided into two parts up and down by its middle part,
The leading-out terminal that two parts are formed is separately positioned on the upper and lower ends portion of solar module.
The quantity that the present invention is divided according to solar cell piece each in solar module, using it is corresponding it is multiple go out
The outlet method of line end can both obtain suitable voltage class in commonly used environment in this way, to solve high-efficiency battery group
The matching problem of part voltage and current and photovoltaic generating system back segment equipment, can also realize solar panel under special circumstances
The string of each section and free between part.
