Solar battery module and solar battery array

摘要

A solar battery module (40) includes a stack of: a plurality of solar battery strings (30) and bus sections (32) connected to both ends of each of the plurality of solar battery strings (30); flexible resin layers (33a through 33c); and a flexible resin film (34). The flexible resin layers (33a through 33c) and the flexible resin film (34) have, on a light receiving surface side of solar battery cells (20), holes through which the bus sections (32) are each partially exposed. The exposed parts of the bus sections (32) serve as a respective plurality of electrically-connecting means (32a). A solar battery array (41) includes a plurality of solar battery modules (40). The plurality of solar battery modules (40) are electrically connected with each other via the plurality of electrically-connecting means (32a). This makes it possible to achieve a large-scale solar battery array (41) with high mechanical strength.

主权项

1. A method for producing a solar battery array that is constituted by a plurality of solar battery modules,
each of the plurality of solar battery modules including:
at least one solar battery string that is constituted by a plurality of solar battery cells electrically connected in series with each other,bus sections electrically connected with respective endmost ones of the plurality of solar battery cells that constitute said at least one solar battery string, andat least one flexible resin layer provided on each of both sides, which are a first side and a second side, of said each of the plurality of solar battery modules so as to sandwich said at least one solar battery string and the bus sections, the method, comprising the steps of: (a) forming first holes, through which the bus sections are each partially exposed, on the first side of the both sides of said each of the plurality of solar battery modules; and (b) electrically connecting said each of the plurality of solar battery modules and another one of the plurality of solar battery modules via areas of the bus sections which areas are exposed through the respective first holes, the areas serving as a respective plurality of electrically-connecting means.
