Title: Solar battery module and its installing method
Inventor: MAKITA HIDEHISA
IPC: H01L31/04
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To give strength as a structure to solar battery module without using a heavily equipped frame and simply execute and install, by a method wherein opposite two frames are bent at an angle in the specified range. SOLUTION: In a solar battery module 101, a reverse face metal reinforcing plate 106 in a region excluding an electricity generating region of the solar battery module is bent at 180 deg.. Thus, it is possible to enhance structure strength of the solar battery module as compared with a flat solar battery module, and simultaneously a renforcing body is inserted into a bent space, whereby it is possible to decide the structure strength of the entire module corresponding to necessary strength. Thus, since this bent part and the reinforcing body can display the equivalent effects to a frame body, the frame body is unnecessary, and as the result, it is possible to reduce costs of the solar battery module. Further, as a weight of the module can be decreased, a heavily equipped frame used when an aluminum frame is fixed can be changed to a light and simple frame.
