The invention discloses a solar photovoltaic module which comprises a photovoltaic power generation module, an intermediate connecting layer and a supporting back plate which are sequentially stacked, wherein the supporting back plate is provided with a noise reduction and heat insulation layer. According to the invention with the structure, the sound insulation and heat insulation functions can be better realized by arranging the sound attenuation and heat insulation layer, the fireproof and heat insulation functions are realized, and the self-explosion risk of the conventional photovoltaic curtain wall glass is avoided. And through setting up the amortization insulating layer in supporting the backplate, can overcome the expend with heat and contract with cold phenomenon and the degree of supporting the backplate to a certain extent, increase of service life. |
