NOVELTY - The method involves connecting crystal system photovoltaic cells mutually and electrically (S120), and producing a crystal system solar cell module. Characteristic value obtained by heating the photovoltaic cells before a connection and concern on an electric power generation performance of the photovoltaic cell is compensated (S124), where the characteristic value is more than a predetermined value. Difference of characteristic values input from measurement parts is computed (S103). Storing time of the photovoltaic cells is input (S110) in a control apparatus.    USE - Method for manufacturing a back surface electrode type crystal system solar cell module. Can also be used for manufacturing a double-sided electrode type crystal system solar cell module.    ADVANTAGE - The method enables heating the crystal system photovoltaic cells to which predetermined time progress is carried out and providing the characteristic value regarding electric power generation performance such that the crystal system photovoltaic cell is mutually connected in unit state, so that electric power generation performance of the crystal system solar cell module can be stabilized. The method enables manufacturing the crystal system solar cell module without performing heating operation by a heating part when characteristic value is less than the predetermined value, so that efficiency improvement of manufacturing process of the crystal system solar cell module can be attained.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a manufacturing system for a crystal system solar cell module.
