A solar cell module 60 has a plurality of solar cells 14 having a plurality of parallel grooves 8 on the individual light-receiving surfaces thereof, each of the grooves having an electrode 5 for extracting output on the inner side face (electrode-forming inner side face) on one side in the width-wise direction thereof; and a support 10, 50 for supporting the solar cells 14 in an integrated manner so as to direct the light-receiving surfaces upward. The annual power output can be increased by adjusting the direction of arrangement of the electrode-forming inner side faces of the grooves 8 while taking the angle of inclination beta of the light-receiving surface of the individual as-installed solar cells 14 relative to the horizontal plane and the latitude delta of the installation site of the solar cell module into consideration. This successfully provides the solar cell module capable of equalizing the output current from the individual solar cells in the module even when the sunlight obliquely irradiates the module. <IMAGE>
