A method is disclosed for installing a solar cell module, which enables easy installation of a solar cell module on a rack, and also enables a worker to install a solar cell module without climbing on the roof. A solar cell module is installed on a rack mounted on a roof. The solar cell module includes a frame formed of a material containing a resin. The rack includes multiple rails each having a groove, and the grooves of a pair of the rails are disposed to be opposed to each other. The method of this invention comprises the steps of fitting the frame of the solar cell module into the groove such that the solar cell module is retained by the pair of the rails, and fixing the solar cell module to the pair of the rails to prevent the solar cell module from falling out of the grooves.

A solar cell rear surface protection sheet having two or more substrates laminated together by means of an adhesive, the adhesive includes a urethane resin obtained by mixing an acrylic polyol, an isocyanate compound, 3-glycidoxypropyltriethoxysilane, and tin octylate. The acrylic polyol is obtained by polymerizing polymerizable monomers, which include a hydroxyl group-containing monomer and other monomers. The other monomers include acrylonitrile. The isocyanate compound includes both a xylylene diisocyanate monomer and hexamethylene diisocyanate isocyanurate, and the xylylene diisocyanate monomer is present in an amount of 20 to 40 wt %, and the hexamethylene diisocyanate isocyanurate is present in an amount of 80 to 60 wt %. The equivalent ratio of isocyanate groups of the xylylene diisocyanate monomer and the hexamethylene diisocyanate isocyanurate to hydroxyl groups of the acrylic polyol is 1.0 to 3.0.
