About this product

What it is, and what it is for

The JA Solar JAM66D45 LB 625W 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 TOPCon half-cell technology across a 132 (6×22) cell configuration, the JAM66D45 LB achieves cell conversion efficiency approaching 26% and a module efficiency of up to 23.0%, ensuring maximum output per square meter. Key electrical parameters at STC include an open-circuit voltage (Voc) of 48.70V, short-circuit current (Isc) of 16.15A, maximum power voltage (Vmp) of 40.45V, and maximum power current (Imp) of 15.45A. The bifacial double-glass design enables energy generation from both sides of the panel, adding meaningful rear-side power gain depending on ground albedo and 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 rated for a maximum static load of 5400 Pa on the front (snow) and 2400 Pa on the rear (wind), and is backed by a 12-year product warranty and a 30-year linear power output warranty (1% first-year degradation, 0.4% annual thereafter), ensuring reliable energy generation for decades.

With a 1500V max system voltage, a footprint of 2382 × 1134 × 30mm, and a weight of approximately 33.1 kg, the JA Solar JAM66D45 LB 620W module is a premium choice for solar power plants, large rooftops, and ground-mounted systems demanding high efficiency, durability, and strong long-term returns.

Common questions

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.
