BIPV (building integrated photovoltaics) daylighting roof system with visible vertical part and hidden transverse part

The utility model provides a vertically-visible and transversely-hidden BIPV daylighting roof system, and relates to the technical field of photovoltaic power generation assemblies. Comprising a photovoltaic module, a base, a pressing plate, a cross beam and a keel, the plurality of photovoltaic module arrays are connected to the two sides of the base; a junction box and a connector cable are installed in the space between the base and the photovoltaic assembly. The pressing plates are connected to the tops of the photovoltaic modules on the two sides of the base; the pressing plate is connected with the base through a screw; the keel is connected to the bottom of the base through screws. The cross beam is located between the two bases, and the bottom of the cross beam is connected to the two sides of the keel through elastic pin assemblies. The top of the cross beam is connected between the photovoltaic modules through a connecting module; the top of the cross beam is also connected to the bottom of the phot
