The invention discloses a solar photovoltaic module. The solar photovoltaic module comprises a working assembly and four aluminum alloy frames. The working assembly comprises a working bottom layer formed by mutual pressing and a glass layer pressed on an upper surface of the working bottom layer. The area of the glass layer is larger than that of the working bottom layer. Each aluminum alloy frame comprises an upper part and a lower part; first limiting grooves for allowing the glass layer to insert are formed in one side surfaces of the upper parts; second limiting grooves for allowing the working bottom layer to insert are formed in one side surfaces of the lower parts; sealing layers contacting the upper surface of the glass layer are arranged in the upper parts; each sealing layer includes a rubber pad layer passing through the corresponding upper part, and a sponge layer contacting the upper surface of the glass layer is arranged on a lower surface of the rubber pad layer; humidity sensors are arranged in the rubber pad layers; the humidity sensors pass through the rubber pad layers and contact the sponge layers. The solar photovoltaic module can allow people to timely find the sealing condition between the aluminum alloy frames and the glass assemblies so as to perform repairing in time, and the service life of the invention is prolonged.
