The invention provides a pre-packaging method for a crystalline silicon solar cell dual-glass module. The pre-packaging method comprises the steps of laying a dual-glass module, heating the dual-glass module, performing primary rolling on the dual-glass module, performing rolling and exhausting on the dual-glass module after the heating treatment, and cooling for realizing continuous production for the pre-packaging for the dual-glass module. According to the pre-packaging method, the rolling processing is performed after the step of heating, so that the percent of pass of the product is improved, the processing speed is accelerated, and the working efficiency is improved.
