The utility model relates to a '' snail track '' resistance photovoltaic module, comprising a battery layer module, and aluminum frames installed on the periphery of the battery layer module. The battery layer module comprises a package layer, a battery plate, and a backboard and a glass plate packaging the battery plate, wherein the backboard covers an upper surface of the battery plate, and the glass plate covers a lower surface of the battery plate; a protective layer covers between the glass plate and the battery plate; the package layer is a two-layer structure, comprising a first package layer arranged between the battery plate and the backboard, and a second package layer arranged between the battery plate and the protective layer; the edges on the periphery of the battery plate are respectively bonded with insulation strips through insulation EVA; the insulation strips are located between the first package layer and the battery plate. Through optimizing raw material matching and selecting suitable frames for combination, under the condition of influencing generated output of the photovoltaic module and not increasing production cost, the photovoltaic module can effectively prevent steam from penetration, substantially reduce probability of snail tracks and prolong the service life of the photovoltaic module.
