What it is, and what it is for
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 23.1%, 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 JAM66D45 LB 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.
Ideal Applications
- Utility-scale solar power plants
- Large commercial and industrial PV systems

Before you order.
If yours isn't here, ask an engineer. It costs nothing and it's the step most people skip.
What if I'm not sure this is the right product?
Ask before you order. Send us what you need to run, or your pool or well figures, and an engineer will confirm the choice — it costs nothing. Or use the finder below, which sizes from what you actually run and shows its reasoning.
