What it is, and what it is for
The JA Solar JAM54D41 LB full pallet includes 36 premium N-Type bifacial solar panels, designed for efficient handling, large-scale installations, and reduced logistics cost. This pallet configuration is ideal for installers, EPCs, and commercial solar projects requiring consistent quality and reliable supply.
Manufactured under JA Solar’s DeepBlue 4.0 Pro platform, these black bifacial modules deliver high efficiency, long service life, and excellent performance in real-world conditions.
The JA Solar JAM54D41 LB 450W is a premium N-Type double glass bifacial solar panel from JA Solar’s advanced DeepBlue 4.0 Pro series, designed to deliver high efficiency, long-term reliability, and modern aesthetics. Featuring a sleek black module design, this panel is ideal for residential rooftops, commercial buildings, and premium solar installations where both performance and appearance matter.
Built with advanced n-type Bycium+ monocrystalline cells and 16-busbar (16BB) half-cell technology, the JAM54D41 LB achieves cell conversion efficiency of up to 26% and module efficiency of up to 22.8%, ensuring higher energy output per square meter. The double glass bifacial construction allows the panel to generate power from both the front and rear sides, increasing real-world energy yield under various installation conditions.
This module offers very low LID, excellent low-irradiance performance, and a superior temperature coefficient of −0.29%/°C, enabling stable power generation even in hot and challenging climates. Its robust double-glass structure enhances resistance to moisture, mechanical stress, and harsh environmental conditions.
Certified to withstand 5400 Pa front load and 2400 Pa rear load, the JA Solar JAM54D41 LB is engineered for long-term outdoor durability. Backed by a 12-year product warranty and an industry-leading 30-year linear power output warranty, it delivers reliable performance and long-term energy security for modern solar projects.

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.
