Key Features

High Efficiency & Premium Performance

• 615W rated power output engineered for large-scale installations requiring maximum density and yield.
• Up to 23% module efficiency driven by cutting-edge n‑type Bycium+ cells and 16‑busbar half‑cell technology.
• Bifacial energy gain with an 80% ±10% bifaciality factor, enabling higher rear‑side generation in reflective environments.

Enhanced Reliability

• Double glass construction (2.0mm + 2.0mm) improves resistance to moisture, UV, microcracks, and mechanical stress.
• Superior temperature performance with low Pmax temperature coefficient of –0.29%/°C.
• Outstanding low‑irradiance response, enabling efficient production from dawn to dusk.

Long-Term Warranty & Durability

• 12‑year product warranty.
• 30‑year linear power output warranty, with only 1% first‑year degradation and 0.4% annually thereafter.
• 5400 Pa front load and 2400 Pa rear load ratings for harsh environmental conditions.
