Abstract:
1. A method for regenerating a photovoltaic module in which a light-receiving surface side-sealing resin layer, a photovoltaic cell, an original back surface side-sealing resin layer and a back surface-sealing weatherproof film are laminated sequentially to each other in this order on a light-receiving glass and these components are formed into an integral piece, comprising: peeling the back surface-sealing weatherproof film; laminating a new sealing resin and a new back surface-sealing weatherproof film in a portion in which the film has been peeled; and then curing for crosslinking the new sealing resin that is laminated to form a regenerated back surface side-sealing resin layer, wherein a part or an entire of the regenerated back surface side-sealing resin layer consisting of a two-layer structure consists of the original back surface side-sealing resin layer and the new sealing resin which are laminated together.
