In addition to their durability, bend roof sheets are also highly resistant to weather elements. The metal surface of these sheets is designed to shed water, preventing accumulation that can lead to leaks and structural damage. Furthermore, many bend roof sheets come with protective coatings that enhance their resistance to rust and corrosion, further extending their lifespan. This makes them particularly suitable for regions that experience heavy rainfall or harsh winters.

Semiconductor materials, such as silicon, gallium arsenide, and cadmium telluride, are commonly employed in the manufacturing of solar cells. Each material has a specific bandgap that dictates its efficiency in converting sunlight into electricity. Silicon, for example, has a bandgap of about 1.1 eV, which allows it to effectively utilize a significant portion of the solar spectrum. However, while silicon-based solar cells dominate the market due to their cost-effectiveness, they often operate at efficiencies around 15-22% in real-world conditions.
