Abstract

A solar battery module is provided with a solar battery panel (20) wherein solar battery cells, including a transparent substrate, are arranged; a reinforcing frame (3) arranged on the rear surface of the solar battery panel (20); and a buffer material (31) arranged between the solar battery panel (20) and the reinforcing frame (3). The buffer material (31) has a flat first main surface facing the solar battery panel (20), and a curved second main surface, which faces the reinforcing frame (3), curves in the longitudinal direction of the reinforcing frame (3) and has an arc-shaped across-section protruding to the side of the reinforcing frame (3).

Description

technical field [0001] The present invention relates to a solar cell module installed in a building such as a house or a building to generate electricity using sunlight. Background technique [0002] As a solar cell module, there is a structure in which a transparent substrate (glass) is arranged on the light-receiving surface side, a plurality of solar cell units connected in series or in parallel are arranged on the back side of the transparent substrate, and these plurality of solar cells are sealed with a sealing resin. The battery cells constitute a solar cell panel, and a frame is attached to the peripheral portion of the solar cell panel. [0003] Solar battery modules are generally installed in buildings such as houses and buildings, and are exposed to wind and rain. Since solar cell modules are used in such a severe environment, the strength against wind load or snow load is one of the indicators of product quality. In recent years, in order to reduce the price pe...
