Younaide "Roof photovoltaic support system" adopts high-quality aluminum alloy with stable corrosion resistance. The lightweight products and modular installation provide convenient conditions for the later roof operation and maintenance, and realize the cost reduction and efficiency increase of the whole roof power station. In strict accordance with the double standards of photovoltaic and building protection, the site effectively helps the roof life and power generation income period of industrial and commercial projects to extend to 25 years. Perfect adaptation to the actual building conditions, the aesthetic integration of photovoltaic and building, and ultimately achieve a double benefit of "photovoltaic + building".
