605W JA Solar Bifacial JAM66D4

The 605W JA Solar Bifacial JAM66D45 LB module is a high‑efficiency n‑type double‑glass solar panel designed for commercial, industrial, and utility‑scale applications. Engineered with JA Solar’s advanced Deep Blue 4.0 Pro technology, it delivers exceptional power output, improved temperature performance, and superior long‑term reliability.

High‑Efficiency n‑Type Bifacial Design

This module features n‑type Bycium+ cells, 16‑busbar half‑cell architecture, and an optimized bifacial structure capable of capturing additional energy from the rear side. With a module efficiency of 22.4%, it achieves strong performance even under low‑irradiance and high‑temperature conditions.

Long‑Term Reliability and Warranty

The JAM66D45 series offers:

• 12‑year product workmanship warranty
• 30‑year linear power output warranty
• Low degradation: 1% in the first year and only 0.4% annually thereafter

The double‑glass construction improves structural integrity and enhances durability in harsh outdoor environments.
