Monocrystal half-piece photovoltaic module string arrangement mode

Abstract

The invention discloses a monocrystal half-piece photovoltaic module string arrangement mode, comprising the following steps of A, cutting a whole battery piece into half battery pieces; B, enabling Nhalf battery pieces to be connected in series and welded into a single string based on consistent chamfer angle direction; C, after the half battery pieces are connected in series and welded into single strings, enabling the battery strings to be arranged on glass paved with an adhesive film based on consistent chamfer angle direction for arrangement; D, after arrangement is completed, enabling the single strings to be connected in series by busbars into an integrated body; E, in serial connection, enabling the tail parts 1 and 2 strings to be connected in series, 3 and 4 strings to be connected in series and 5 and 6 strings to be connected in series, and enabling the head part 1 string to be connected singly, 2 and 3 strings to be connected in series, 4 and 5 strings to be connected in series and 6 string to be connected singly; and F, after string connection is completed, adding an adhesive film and an insulation cushion strip between the upper and lower busbars on the head part insequence, and then paving a back surface adhesive film, a back plate or back surface glass in sequence, and gluing a glass surface bar code and the like to complete a stacking operation. The half battery pieces are consistent in chamfer angle arrangement direction, so that the attractive degree of the module is improved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic modules, in particular to a method for stringing single crystal half-chip photovoltaic modules. Background technique [0002] Photovoltaic modules are composed of solar cells or a combination of solar cells of different specifications cut by a laser cutting machine or a steel wire cutting machine. Since the current and voltage of a single solar cell are very small, then we first connect them in series to obtain a high voltage, and then connect them in parallel to obtain a high current, and then output it through a diode (to prevent current return). Photovoltaic modules (also called solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system. Its function is to convert solar energy into electrical energy, and send it to the storage battery for storage, or to drive the load to work; however, with the use of the micro-inv...

Problems solved by technology

Its function is to convert solar energy into electrical energy, and send it to the storage battery for storage, or to drive the load to work; however, with the use of the micro-inverter, the current source of the photovoltaic module can be directly converted into a voltage source of about 40V. It can drive electrical appliances in our life; at the same time, photovoltaic modules are constantly innovating. Since photovoltaic modules are called Chinese manufacturing in the industry, they should be created in China, and then there are upgraded and innovative products of photovoltaic modules, such as photovoltaic ceramic tiles and photovoltaic color steel. Tile, this kind of product can directly replace traditional building material tiles, and has the function of photovoltaic modules. Once it enters the general market, it will have a certain impact on photovoltaic modules and traditional building materials.

[0003] With the rapid development of the photovoltaic market, photovoltaic power generation has penetrated into various environments. For this reason, the majority of photovoltaics artificially increase the power of components to adapt to different environments, and actively develop various components to meet the needs of the market. Among them, Half-cell modules are favored for their low loss and high power. However, due to the chamfers at the four corners of monocrystalline cells, the current arrangement of monocrystalline half-cell modules on the market is two adjacent strings or The four strings of chamfers are arranged alternately, which affects the appearance of the module. Therefore, a string arrangement method with uniform chamfers of single crystal half-cut modules is invented. This method not only has the same characteristics as half-cut modules, but more importantly increases Overall aesthetics of components
