PU Pultruded Solar Module Frames

PU Pultruded Solar Module Frames represent a cutting-edge advancement in photovoltaic (PV) module support structures. Utilizing polyurethane (PU) composites through the pultrusion process, these frames offer a superior alternative to traditional aluminum frames. They provide enhanced mechanical strength, exceptional corrosion resistance, and improved thermal compatibility with solar glass, making them ideal for diverse environmental conditions. Their lightweight nature and insulating properties further contribute to the efficiency and longevity of solar installations.
