The invention relates to a double-bottom-coating FPC structure photovoltaic panel. The double-bottom-coating FPC structure photovoltaic panel is characterized in that a solar battery backboard is of an FPC structure, a PET film layer is arranged in the middle of the FPC structure, a first bottom coating is arranged on the upper surface of the PET film layer, a second bottom coating is arranged on the lower surface of the PET film layer, an outer Teflon coating layer making contact with air is arranged on the first bottom coating, and an inner Teflon coating layer adhering to an assembly packaging glue film is arranged on the lower surface of the second bottom coating. The double-bottom-coating FPC structure photovoltaic panel not only can meet the use requirements under atrocious outdoor weather conditions, but also is long in service life and low in backboard performance retention rate.
