The Story
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.
Mechanical Specifications
- Dimensions: 2382 × 1134 × 30 mm
- Weight: 33.1 kg
- Cell configuration: 132 mono n‑type cells (6×22)
- Glass: 2.0 mm front and back double‑glass
- Junction box: IP68 rated
- Connectors: QC4.10‑351 / MC4‑EVO2A
- Load ratings: 5400 Pa front, 2400 Pa rear
Perfect for trackers, rooftop installations, and ground‑mounted systems requiring high power density.
Electrical Performance (605W Model)
- Rated Power (Pmax): 605 W
- Open Circuit Voltage (Voc): 47.90 V
- Maximum Power Voltage (Vmp): 39.60 V
- Short Circuit Current (Isc): 16.00 A
- Maximum Power Current (Imp): 15.28 A
- Power Tolerance: 0 to +3%
Optimized for All Conditions
This module excels in:
- Low‑light environments
- High‑temperature climates
- Systems benefiting from rear‑side bifacial gain
Its advanced temperature coefficient and bifaciality make it a strong performer across diverse installation types.
