Key Structural Features
- Half-Cell Architecture: Splitting the cells into two equal halves halves the internal current. This design lowers resistive losses and maintains production even under partial shading conditions.
- Multi-Busbar Technology: Shorter current pathways across individual cells reduce internal resistance and elevate total power density.
- Lower Hot-Spot Risks: Operating at lower inner currents reduces localized cell overheating. This design extension enhances long-term reliability and guards against backsheet damage.
- Enhanced Load Tolerances: Certified to withstand strict mechanical strain, including frontline front-side snow loads up to 5400 Pa and rear wind pressure up to 2400 Pa.
