- Frame Color: Silver or customizable Black Frame (BFR)
- Backsheet/Foil Color: White
- Connector Type: MC4 or MC4-compatible
Performance & Temperature Behavior
- Temperature Coefficient of Pmax: -0.35 %/°C
- Maximum System Voltage: 1000V DC
- Mechanical Loading Capacity: Certified to tolerate high wind and heavy snow loads.
Core Technology Advantages
- Half-Cell Configuration: Splitting the standard 60-cell layout into 120 half-cells halves the internal electrical current. This greatly reduces resistive losses and increases overall power output.
- Multi-Busbar (MBB) PERC: Passivated Emitter and Rear Cell (PERC) technology increases light absorption. Multi-busbars shorten the distance current must travel, reducing internal resistance and minimizing microcrack risks.
- Better Shading Tolerance: Because the module is split into two independent halves, shading on the bottom half of the panel won't fully shut down the energy generation of the top half.
- Lower Hot-Spot Risks: The lower cell current leads to a significantly reduced risk of localized hot spots, extending the lifespan of the equipment.
