The invention provides a novel protective support for a photovoltaic assembly plate. The novel protective support comprises bound edges I, bound edges II and blocking edges, wherein the bound edges II are arranged between adjacent bound edges I, and the blocking edges are connected between the bound edges I and the bound edges II. The bound edges I, the bound edges II and the blocking edges are used to wrap and protect the four edges of a photovoltaic assembly, thereby preventing deformation of corners of the assembly and damage of the assembly when encountering outer forces. The service life time of the photovoltaic assembly can be prolonged, and the maintenance cost is reduced. The support employed makes installation more convenient, and the installation efficiency is improved.
