Description
Description
The JA Solar JAM66D45 LB 620W is a next-generation N-Type double glass bifacial solar panel designed for high-power commercial, industrial, and utility-scale solar projects. Built on JA Solar’s DeepBlue 4.0 Pro platform, this module delivers superior energy yield, long-term reliability, and lower levelized cost of electricity (LCOE).
Powered by advanced N-Type Bycium+ cells with 16-busbar (16BB) half-cell technology, the JAM66D45 LB achieves up to 26% cell conversion efficiency and module efficiencies exceeding 23%, ensuring maximum output per square meter. The bifacial double-glass design enables energy generation from both sides of the panel, offering up to 10% rear-side power gain under standard conditions and higher gains depending on installation environment.
This solar module features excellent temperature performance with a low power temperature coefficient of −0.29%/°C, delivering stable output in hot climates. It also offers very low LID, improved low-irradiance response, and enhanced resistance to environmental stress, making it ideal for long-term outdoor operation.
Engineered for durability, the JAM72D40 MB is certified to withstand 5400 Pa front load and 2400 Pa rear load, and is backed by a 12-year product warranty and a 30-year linear power output warranty, ensuring reliable energy generation for decades.
Ideal for solar power plants, large rooftops, and ground-mounted systems, the JA Solar JAM66D45 LB 620W module is a premium choice for projects demanding high efficiency, durability, and strong long-term returns.
