Abstract
The utility model discloses a solar battery assembly, which comprises a plurality of solar battery sheets and is characterized in that the plurality of solar battery sheets are separated into two groups with same quantity, each group of solar battery sheets are mutually connected in series to form a branch circuit, and two branch circuits are connected in parallel to be connected with a junction box to output. The solar battery sheets are made of standard solar battery sheets which are cut into two equal parts along the grid line direction. In the solar battery assembly, the standard solar battery sheets are cut into two equal parts which are then connected in series, current on a single battery is 1/2 of that of a regular assembly, produced heat energy is 1/4 of that of a regular battery, possibility for generating heat spots is greatly reduced, welded-stripe resistance reduces by 1/4, and loss of the assembly is reduced. Current and voltage finally output by the circuit are not changed, so that using scope of the solar battery assembly is same with that of the regular assembly, while efficiency of the assembly is improved.
Description
Technical field
The present invention relates to a kind of solar module.
Background technology
Along with heliotechnics make rapid progress flourish, need continually develop out the better solar module product of quality and performance.Therefore, in assembly new-product development, trial-production, production, use, the various demands of solar module are also in continuous increase.
In the conventional solar panel, the battery sheet is all connected, circuit diagram such as Fig. 1, and the assembly output current is consistent with battery sheet electric current.Like the assembly that the battery of conventional monocrystalline 156 is made, all about 8.5A, assembly possibly surpass 9A to electric current efficiently, and it is that heating is very serious that hot spot is arranged.When a slice battery in the assembly or a Battery pack sheet were blocked or damage, operating current had surpassed the short circuit current of this battery or battery pack, in assembly, the hot spot heating can take place.This moment, affected battery or battery pack were placed in reverse-bias state, thus cause overheated, consumed power, this is one of major reason of component failures.
The utility model content
The utility model has proposed a kind of solar module to the above-mentioned defective that prior art exists, and can effectively reduce the hot spot heating phenomena of battery sheet in the assembly.
The basic ideas that the utility model is dealt with problems are: if be cut into the battery sheet original half the, electric current will be for original 1/2 in the assembly, can drop to 4.5A like the electric current of 9A, and the shielding plate all-in resistance is constant, and thermal losses is I
2R, it is original 1/4 that heating will become, and the assembly damage that hot spot causes reduces greatly.With battery sheet area become original half the after, battery sheet voltage does not lose.If guarantee the invariable number of battery sheet, only be that battery sheet area is original half the, be composed in series a branch road; Then two identical branch roads are together in parallel, the electric current in each branch road of assembly is 1/2nd, and output current, voltage total in the assembly main line are preceding consistent with cutting again; As shown in Figure 2; The power output of assembly is also constant, and the scope of application of assembly can not change yet, but security performance improves greatly.And after the cutting of battery sheet, welding resistance total losses also can reduce, thereby component power is promoted to some extent.
The utility model is for the technical solution problem, and the technical scheme that is adopted is:
A kind of solar module comprises several solar, it is characterized in that: quantity such as several solar are divided into two groups, and every Battery pack sheet is connected each other and is become branch road, again with two branch road parallel connections, connects terminal box output.
Said solar battery sheet is to cut into two five equilibriums by the standard solar cells sheet along the grid line direction to process.
Wherein, said solar battery sheet goes for all standard solar cells sheet full wafer assemblies, like existing 72 solar cell chip modules, can change two 72 two/a slice series arms into according to this kind screening mode, so latter two branch road parallel connection again; Conventional 60 solar cell chip modules can change two 60 two/a slice series arms into according to this kind screening mode, so latter two branch road parallel connection again; And the like.
Said solar battery sheet is and is cut into 1/2 battery sheet, can be monocrystalline 125, monocrystalline 156, polycrystalline 125, polycrystalline 156.
The superiority of the utility model is:
In this utility model solar module; Standard cell sheet (claiming the conventional batteries sheet again) is cut into two five equilibriums along the grid line direction, series connection then, the electric current on the monolithic battery is 1/2 in the conventional assembly; The heat energy that produces is 1/4 of conventional batteries; Greatly reduce the possibility that produces hot spot, welding resistance has also reduced by 1/4, has reduced the loss of assembly.And the current/voltage of the final output of circuit can not change, so its scope of application is consistent with conventional assembly, but the efficient of assembly can improve.
