Product Advantages
The 520 product is the world’s first 520W hail-resistant, micro-crack free flexible crystalline silicon module, featuring six key characteristics: “Lightweight & Thin, Flexible, Strong, Easy Installation, Aesthetically Pleasing.” Its advantages are detailed below:
- Lightweight & Thin: Merely 1.8 mm thick and weighing only 2.9 kg/m² (less than 30% of traditional glass modules), facilitating transportation, handling, and installation.
- Flexible: Bendable with a minimum bending radius of 0.3 m, adaptable to various curved and irregular installation scenarios, expanding photovoltaic application possibilities.
- High Strength: Incorporates self-developed high-strength nanofiber reinforcement material (5 times stronger than steel). Withstands impact of 25 mm diameter hail at 82.8 km/h with degradation less than 1/5 of international standards. Also endures external forces like stepping and vehicle pressure, offering excellent impact resistance and durability.
-
High Efficiency: Employs high-efficiency monocrystalline silicon cells with ≥20% photoelectric conversion efficiency on module active area. First-year efficiency degradation ≤2.5%, followed by ≤0.5% annual degradation. Maintains ≥85% efficiency after 25 years, ensuring long-term stable high power generation efficiency.
-
Easy Installation: Suitable for various low-load roof scenarios (e.g., color steel tile, glazed tile) using structural adhesive fixation without drilling, hot work, or roof damage. Significantly reduces construction time, installation cost, and complexity.
-
Aesthetically Pleasing: Allows customized installation according to different architectural appearances and requirements, achieving better integration with buildings, enhancing overall aesthetics, and realizing perfect building-integrated photovoltaics (BIPV).
