JA Solar JAM66D45-625/LB — 625 Wp, n-type TOPCon

The JA Solar JAM66D45-625/LB is a high-power bifacial glass–glass module based on n-type TOPCon cells with a nominal output of 625 Wp. According to the manufacturer datasheet, it offers a high module efficiency (≈22–23% range for the 66D45 family), a large footprint for high-power utility and commercial arrays (~2382 × 1134 × 30 mm), and a robust weight of roughly ~33 kg; it’s specified for 1500 V system operation, has a low temperature coefficient (Pmax ≈ −0.29%/°C), and is backed by bankable warranties (manufacturer product warranty and a 30-year linear power guarantee). Key mechanical and certification specs (e.g. front 5400 Pa / rear 2400 Pa, IP68 junction box, IEC/UL standards) are included in the official datasheet. 

✅ Benefits for installers

Very high single-module power — 625 Wp: fewer modules per MWp and lower BOS cost.
High efficiency (66D45 family): high W/m² reduces roof/land footprint and increases yield.
Bifacial glass–glass construction: additional rear-side energy on reflective surfaces and improved long-term durability.
1500 V system rating: enables longer strings and lower inverter/BOS cost.
Rugged mechanical spec: high static loads (typ. 5400 Pa front / 2400 Pa rear) for snow/wind resistance.
Bankable warranty & certifications: long performance guarantee plus IEC/UL/ISO certifications for financing confidence.
