    These newly developed insulated metal roof panels are designed for photovoltaic projects, providing both structural support and reliable insulation. They combine thermal protection, noise reduction, and a clean decorative finish in a single solution. The ribbed interlocking system allows solar modules to be fixed with special clips instead of drilling, protecting the roof and lowering installation costs on large-scale projects.

    Applications

    These insulated metal roof panels can be used in both industrial and residential roofing projects. They are also suitable for public buildings such as schools, hospitals, shopping centers, and community housing. In addition, they are widely applied in roof renovations for old factories and the upgrading of existing buildings.

    • Eliminates the need for traditional aluminum rails and clamps, cutting both material and labor costs.
    • Resistant to strong winds, seismic loads, and water penetration, while providing insulation, noise reduction, durability, and energy efficiency.
    • Features self-cleaning properties, strong weather and corrosion resistance, and low maintenance requirements.
    • Lightweight design makes installation easier, with no need for heavy lifting equipment, improving overall efficiency.
    Material Composition

    Metal sheet

    • Galvalume steel sheet
      Corrosion resistance typically 2–6× higher than regular galvanised steel, with good heat/oxidation resistance and high solar reflectance that helps lower interior temperatures (energy saving). Compared with titanium-zinc and Al-Mg-Mn sheets, it offers a strong cost-effectiveness.
    • Titanium–zinc sheet
      Produced from high-purity zinc (99.995%) alloyed with titanium (0.06–0.20%) and a small amount of copper. Very long service life (~80–100+ years in suitable conditions). Forms a protective patina that self-heals minor scratches. Good ductility for curved or complex shapes.
    • Al-Mg-Mn alloy sheet
      Lightweight, high strength and corrosion-resistant, available with many finishes and colours. 100% recyclable; typical service life 50+ years.

    Coating layer

    • PE (Polyester)
      Good adhesion and flexibility, moderate chemical resistance. Typically lasts 7–10 years.
    • HDP (High-Durability Polyester)
      Stronger UV and weather resistance, more durable than PE but more cost-effective than PVDF. Service life of 10–15 years.
    • PVDF (Fluorocarbon coating)
      Offers the best colour stability, weather resistance, and protection against fading or chalking. Designed to last 15–20 years.

    In building-integrated photovoltaics (BIPV), the metal sheets are usually made from galvalume steel or aluminum-magnesium-manganese alloy. Both are lightweight, resistant to corrosion, and designed for long service life. For example, aluminum-magnesium alloys can last up to 50 years in normal conditions, which makes them very reliable for roofing applications.

    Yes. Solar roof panels are flexible enough to be used on flat or sloped roofs. The actual tilt angle depends on the local climate and the hours of effective sunlight. In regions with lower solar exposure, adjusting the angle helps improve energy efficiency.

    Compared to single-layer roofing sheets, insulated solar roof panels have a layered design. When rigid polyurethane foam is used as the core, it improves thermal and acoustic performance. This reduces common issues such as rain noise, wind impact, and outside mechanical sounds, so they are suitable even for hospitals, schools, or residential projects where a quieter environment is important.

    For areas exposed to high winds and typhoons, standing seam metal roofs with a 360° seam clamps are recommended because the panels interlock securely and resist uplift. Concealed fixed roofing sheets are also an option; they offer strong wind resistance without visible fasteners, which also improves durability and appearance.
