Non-penetrating PV Mounting is a mounting system designed for concrete flat roofs. Prefabricated concrete counterweights are used to avoid drilling holes to damage the roof waterproofing layer. The main body is made of hot-dip galvanized steel or aluminum alloy, which is corrosion-resistant and lightweight, and supports 10°-30° tilt adjustment to optimize lighting efficiency. It is suitable for double-glass components and lightweight photovoltaic panels. It is quick to construct and has low maintenance costs. It is widely used in concrete flat roof scenes such as industrial and commercial plants, public buildings, etc., taking into account the needs of efficient power generation and long-term roof protection.
