PROBLEM TO BE SOLVED: To provide a rework method for a solar battery module in which the adhesion strength between a back-surface protection sheet and a sealing material sheet at normal temperature after long-term lapse is excellent, and the back-surface protection sheet can be easily re-covered under a specific condition.SOLUTION: According to a rework method for a solar battery module, in a solar battery module manufacturing process in which a surface protection sheet, a sealing material sheet 1, a photovoltaic power generation element, a sealing material sheet 2 and a back-surface protection sheet are laminated in this order and subjected to heat-and-press molding to be integrated with one another, only a back-surface protection sheet in which a defect has occurred is exfoliated while heating the molded solar battery module at a temperature ranging from not less than 50°C to not more than 150°C, and new sealing material sheet and back-surface protection sheet are laminated and subjected to heat-and-press molding again. |
