It threatens.Respective energy development strategy is formulated in countries in the world one after another, to cope with the finiteness and exploitation of conventional fossil energy resources
Utilize bring environmental problem.Solar energy relies on its reliability, safety, popularity, longevity, the feature of environmental protection, resource adequacy
The characteristics of have become one of most important renewable energy, be expected to become the mainstay of the following global power supply.
During new round energy revolution, it is emerging that China's photovoltaic industry has grown into the strategy with international competitive advantage
Industry.However, theCourse of PV Industry still faces problems and challenge, transfer efficiency and reliability are to restrict theCourse of PV Industry
Maximum technology barrier, and cost control and scale economically form restriction.Core of the photovoltaic module as photovoltaic power generation
Center portion part, improving its transfer efficiency to develop efficient component is inexorable trend.Various efficient components are emerged in large numbers currently on the market,
Such as imbrication, half, more main grids, double-side assembly.As the application places of photovoltaic module and application area are more and more extensive, to it
Reliability requirement is higher and higher, especially needs in some severe or extreme weather prone areas using efficient, high reliability
Photovoltaic module.
Widely popularize and background using solar energy green energy resource under, imbrication component utilizes the low-loss electricity of low current
Principle (square direct proportionality with operating current is lost in photovoltaic module power) is so that component power loss is dropped significantly
It is low.It generates electricity secondly by piece pitch area is made full use of in battery component, unit area self-energy density is high.In addition make
With the conductive adhesive with rubber elastomer characteristics instead of general components photovoltaic metal welding band, since photovoltaic metal welding band exists
Show higher series resistance in full wafer battery and the stroke of conductive adhesive current loop will be much smaller than the side using welding
Formula, to finally make imbrication component become efficient component, while outdoor application reliability is compared with conventional photovoltaic assemblies performance
It is more excellent, because imbrication component avoids metal welding band and damages to the stress of battery and battery interconnection location and other doab domains
Wound.Especially under the dynamic of high/low temperature alternation (load of the natures such as wind, snow acts on) environment, is interconnected and sealed using metal welding band

Deng buying, difficult and the effective tempering of current glass width is mostly in 1050mm hereinafter, the sheet glass of excessive wide cut is in tempering mistake
It will cause the appearance of glass edge tempering uneven phenomenon in journey, can not ensure that the mechanical strength of imbrication component, prolonged application are a kind of
Security risk.Secondly, being encapsulated using short battery strings, battery strings number is significantly increased, and increasing production process task difficulty reduces life
Produce process efficiency.Although the standardized size of 992mm may be implemented in vertical version type wide cut, it is difficult that long string bypass confluence draws processing
Degree height, process point complexity, fragment height etc. greatly limit long string of advantage.Pass through confluence end lead interconnection growth in short battery strings
Battery strings can not be suitble to 6 small pieces and the above equal part to interconnect the voltage requirement of output by the way of full parallel output.I.e. with small
The long full parallel-connection structure output voltage of string of the increase of number of batteries increases, and influences the design of system end square matrix, compatibility is poor.
