JA Solar 470W N-Type Double-Glass Monofacial Solar Panel – Black Frame
The JA Solar JAM54D-40-470-LR-TS-MC4 is a 470 W N-type double-glass monofacial solar panel featuring MBB (multi-busbar) half-cell technology in a 54-cell configuration. With 23.5% module efficiency, a temperature coefficient of -0.29%/°C, dual-glass construction, and lower LID (light-induced degradation) inherent to N-type cell technology, this panel delivers reliable performance for residential and commercial PV systems. Part of the JA Solar Integrated Traceable System (ITS) for full supply chain traceability. Black frame. 1,500 V DC maximum system voltage. MC4-EVO2 connectors. Clamping on long and short sides. 25-year product warranty, 30-year performance warranty. MCS certified. Available from DECO Group, a UK-based solar trade wholesaler.

Common Questions
Click a question below to reveal the answer.
What does "LR" and "TS" mean in the model number?
LR indicates a low-resistance variant for improved performance. TS indicates the panel is part of the JA Solar Integrated Traceable System (ITS), providing full supply chain traceability from cell to module.
What are the advantages of N-type over P-type panels?
N-type panels offer lower LID (light-induced degradation), better weak illumination response for improved low-light generation, and a better temperature coefficient, resulting in higher energy yield over the system lifetime.
Can this panel be clamped on the short side?
Yes. Unlike some panels that only support long-side clamping, the JA Solar 470 W supports clamping on both long and short sides, giving installers more flexibility in mounting orientation.
Is this panel MCS certified?
Yes. The JA Solar 470 W is MCS certified, qualifying for the Smart Export Guarantee in the UK.
