A double-glass photovoltaic assembly includes a laminate member, a junction box, and a first frame and a second frame disposed only at two long sides of the laminate member. The laminate member includes a cover plate glass, a first encapsulation adhesive film, a battery string, a second encapsulation adhesive film, a back plate glass, and a busbar. A through-hole is provided at the back plate glass. An end of the busbar is connected to the battery string. Another end of the busbar passes through the through-hole, and is bent to form a bent edge to be connected to the junction box. The bent edge of the busbar does not contact an edge of the through-hole. The double-glass photovoltaic assembly adopting a double-frame design can meet the requirements of load capacity.
