Installation method of photovoltaic support

The invention discloses a photovoltaic support installation method, the photovoltaic support comprises a photovoltaic support body and a photovoltaic panel arranged on the photovoltaic support body, the photovoltaic support body comprises a base, a stand column, an oblique beam and a purline, the upper end face of the base is provided with a socket cup opening, the lower end of the stand column is inserted into the socket cup opening, and the lower end of the oblique beam is inserted into the socket cup opening. The two adjacent stand columns are connected through the oblique beams, the two adjacent oblique beams are connected through the purlines, and the base, the stand columns, the oblique beams and the purlines are all reinforced concrete prefabricated parts; and the photovoltaic panel is mounted on the purline. The prefabricated reinforced concrete member is low in manufacturing cost, durable, safe and reliable, on-site foundation pile operation is greatly reduced, modular installation in an inserting an
