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. 【課題】常温、長期径時後の裏面保護シートと封止材シートとの密着強度に優れ、特定の条件においては裏面保護シートの容易に張り替え可能な太陽電池モジュールのリワーク方法を提供する。【解決手段】表面保護シート、封止材シート１、太陽光発電素子、封止材シート２、および裏面保護シートをこの順に積層し、加熱圧着成型により一体化する太陽電池モジュールの製造過程において、成型後の太陽電池モジュールを５０℃以上１５０℃以下に加熱しながら不具合の生じた裏面保護シートのみを引き剥がし、新たな封止材シートと裏面保護シートを積層して再度加熱圧着成型する太陽電池モジュールのリワーク方法。【選択図】なし
