Problems solved by technology

In addition, since the existing solar battery modules need to be electrically connected through the bus ribbons located beside the solar battery array and the interconnection ribbons located between the solar battery units, a large area needs to be reserved between the solar battery units. The separation distance, that is to say, the design of the existing solar cell module, the proportion of the area that cannot contribute to the conversion efficiency (power generation efficiency) is relatively high

Embodiment Construction

[0041] Figure 1A It is a schematic structural diagram of a solar cell module according to an embodiment of the present invention. Figure 1B for Figure 1A A schematic diagram of a partial cross-sectional structure along the line A-A in the middle. see Figure 1A and Figure 1B , the solar cell module 100 includes a plurality of solar cell units 110 and connectors 120 . A plurality of solar battery units 110 are arranged in an array, and the connector 120 is disposed between the solar battery units 110 .

[0042] In a vertical projection direction, the solar cell units 110 do not overlap with each other, and are arranged in a two-dimensional array, so as to have a plurality of solar cell rows D1 and a plurality of solar cell columns D2 . Wherein, the solar cell row D1 is a solar cell string along a column direction, and the solar cell column D2 is a solar cell string along a column direction. The solar cell units 110 in the same solar cell row D1 are connected in series th...

Abstract

A solar cell module includes a plurality of solar cell units and a plurality of connectors. A plurality of solar cell units are arranged in a two-dimensional array to have a plurality of solar cell rows and a plurality of solar cell columns. The connecting piece is disposed between two adjacent solar battery columns. The connector has an upper part, a middle part and a lower part connected in sequence. Wherein, a plurality of solar cell units in the same solar cell row are connected in series through the connection elements, and a plurality of solar cell units in the same solar cell row are connected in parallel through the same connection elements.

Description

technical field [0001] The present invention relates to a solar battery module, in particular to a solar battery module including solar battery units connected in series and parallel to each other in electrical design. Background technique [0002] Basically, a solar cell module includes an array of multiple solar cell units, which are sealed to form a solar panel. Generally, when connecting individual solar cell units to form a solar cell module, interconnection ribbons (cell ribbons) are used to bridge the front side of each solar cell unit and the back side of adjacent solar cell units, thereby forming multiple solar cell modules. string of solar cells. Then, a plurality of solar cell strings are arranged in parallel to form a solar cell array. Moreover, at the end of the corresponding solar cell string on the side of the solar cell array, the ends of each interconnection ribbon (cell ribbon) are connected in series with a bussing ribbon. When sunlight is incident on t...
