Abstract

A solar battery module comprises a solar battery panel (1) having solar battery cells (2) formed in a plate shape and arranged on the same plane, a cell protective member so formed in a plate shape as to cover the solar battery cells (2) arranged on the same plane, and a surface protective member adhered to the surface of the cell protective member; an outer frame (7) for holding the outer peripheral part of the solar battery panel (1); and beams (6, 6) each of which has both ends engaged with the opposed two parts of the outer frame (7) and supports the rear surface center part of the soar battery panel (1). An initial tension force is applied to each of the beams (6, 6).

Description

technical field [0001] The present invention relates to a solar cell module, and more particularly to a support structure for a solar cell panel included in the solar cell module. Background technique [0002] In a conventional solar battery module, a plurality of solar battery cells formed in a plate shape and arranged on the same plane are covered with a flexible resin cell protection member such as EVA (ethylene-vinyl acetate copolymer). A surface protection member such as tempered glass is bonded to the surface of the cell protection member to ensure structural strength as a building member. [0003] As a solar cell module whose strength is further improved compared with the above-mentioned conventional solar cell module, there is a solar cell panel, a heat insulator arranged on the back thereof, and a metal plate arranged on the back side of the solar cell are laminated with an adhesive layer interposed therebetween. An integrated solar cell module (for example, refer ...
