625W JA Solar Panel – JAM66D45_LB_BF Black Frame

n‑Type Bifacial Double‑Glass Solar Module | Black Frame | DEEP BLUE 4.0 Pro

The 625W JA Solar JAM66D45_LB_BF is a high‑performance n‑type bifacial solar panel engineered for utility‑scale, commercial, and large rooftop installations where maximum power output, long‑term reliability, and superior energy yield are essential. Built on JA Solar’s DEEP BLUE 4.0 Pro platform, this module combines advanced Bycium+ n‑type cell technology, double‑glass construction, and a sleek black frame for outstanding durability and performance.

Designed to deliver high efficiency and reduced degradation over time, this panel provides excellent LCOE (Levelized Cost of Energy) and strong results in both high‑temperature and low‑irradiance environments.

Key Features and Benefits

• High Power Output – 625W
  Ideal for large systems requiring fewer panels and optimized installation costs.

• n‑Type Bycium+ Cell Technology
  Significantly lower LID (Light‑Induced Degradation) and better long‑term energy retention compared to p‑type modules.

• Bifacial Double‑Glass Design
  Captures additional energy from the rear side, delivering up to 10% additional power gain depending on installation conditions.

• High Module Efficiency
  Up to 23.1% efficiency, delivering excellent power density per square meter.

• Superior Durability
  2.0mm front and back tempered glass, high mechanical load ratings, and resistance to harsh environmental conditions.

• Excellent Temperature Performance
  Lower temperature coefficients ensure stable power production in hot climates.

• Premium Black Frame Finish
  Ideal for projects requiring a professional, uniform aesthetic.
