NOVELTY - The member comprises 75-85 wt.% of fibers (101) extending along an axial direction of the member and a plastic (102) as a matrix. The fibers comprise glass fibers, carbon fibers, and/or metallic fibers. The member: is attached to an entire or a part of a border of a photovoltaic module and a back side of the photovoltaic module through adhesion and/or mechanical connection; and is prepared by a pultrusion process. The member possesses an axial tensile modulus of 20000 N/mm2, an axial flexural modulus of 20000 N/mm2, and a surface electrical resistivity of 1x 1014 Omega .    USE - The member is useful for supporting a photovoltaic module (claimed).    ADVANTAGE - The member: exhibits good mechanical strength and stiffness similar to aluminum profiles, electrical insulation properties, resistance to corrosion and coefficient of thermal expansion compatibility with other materials such as glass used in photovoltaic or solar modules; reduces the possibility of electrical breakdown due to lightening or electrical leakage; decreases the potential induced degradation thus enhancing the efficiency of photovoltaic cells; provides inertness toward chemical and/or electrochemical corrosion thus extending the service lifetime of photovoltaic modules; and can not be easily deformed during transportation, installation and usage.
