The present invention allows a crystalline photovoltaic module having a super straight type structure in which a light-receiving surface side-sealing EVA layer 2, a photovoltaic cell matrix 3, a back surface side-sealing EVA layer 4 and a back surface-sealing weatherproof film 5 are laminated sequentially in this order on a light-receiving glass 1 and these components are formed into an integral piece to be reused after it has been used in the market for a long time by extending the lifetime of the photovoltaic module. The regeneration method includes peeling the back surface-sealing weatherproof film 5, laminating a new back surface side-sealing EVA layer 8 and a new back surface-sealing weatherproof film 9 in a portion in which the film has been peeled, and then curing for crosslinking the new back surface side-sealing EVA layer 8 that is laminated.
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:
