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.

Concealed fixed roofing sheets are also an option; they offer strong wind resistance without visible fasteners, which also improves durability and appearance.
