[0071] Figure 7 It is a longitudinal sectional view showing Embodiments 2 and 3 of the solar cell module of the present invention, Figure 8 It is a partial longitudinal sectional view of a solar cell panel included in the solar cell module according to the second embodiment.

[0072] Such as Figure 7 as well as Figure 8 As shown, the solar cell module 25 according to Embodiment 2 includes: a rectangular plate-shaped solar cell panel 21 in which a plurality of solar cell cells 2 are arranged; Made of rectangular frame-shaped outer frame 7.

[0073] Additionally, if Figure 8 As shown, in the solar cell panel 21, the solar cell unit 2 (in Figure 8 Only one is shown in the figure, but a plurality of solar battery cells are arranged at intervals on the same surface. 2) It is covered with a flexible resin cell protection member 4 such as EVA. A surface protection member 3 made of plate-shaped tempered glass is bonded to the surface. Furthermore, the back plate 14 is bon...

Abstract

The invention provides a solar cell module, which is provided with a solar cell panel, a unit protection part, a surface protection part, a back panel and an outer frame, wherein the solar cell panel consists of a plurality of solar cell units which have a plate shape and are arranged on the same plane; the unit protection part has a plate shape in a form of covering the plurality of solar cell units which are arranged on the same plane; the surface protection part is adhered to the surface of the unit protection part; the back panel is adhered to the back surface of the unit protection part; the outer frame keeps the periphery of the solar cell panel; and the thickness of the back panel is determined to accord with the condition that the unit is close to an inclined neutral axis in the thickness direction of the panel under the condition that the solar cell panel is bent and deformed due to external force applied to the panel.

Description

[0001] This application is a divisional application of the same applicant's Chinese invention patent application with the application date of April 24, 2007, application number 200780052703.7 (PCT / JP2007 / 058852), and the invention name "solar battery module". technical field [0002] 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 [0003] 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. [0004] As a solar cell module whose strength is further improved compared with the above-mentioned conventional solar cell...
