JA Solar JAM66D45-610/LB – 610 Wp, n-Type TOPCon
The JA Solar JAM66D45-610/LB is a 610 Wp n-type TOPCon bifacial glass-glass module that combines high power density with long-term stability. It features 132 cells, a module efficiency of ≈22.6%, dimensions of 2382 × 1134 × 30 mm and a weight of 33.1 kg, plus commercial warranties (12 years product warranty and a 30-year linear performance warranty) — designed for utility and large commercial projects where high yield and durability matter.
✅ Benefits for installers
• High rated power — 610 Wp: more kW per module reduces mounting, labour and BOS costs.
• Good area efficiency (~22.6%): higher energy yield per m² keeps project footprints small.
• n-Type TOPCon cells: lower LID and improved low-irradiance performance for steadier long-term output.
• Bifacial glass-glass construction: additional rear-side generation on reflective surfaces and enhanced module durability.
• Strong mechanical specs: maximum front static load 5,400 Pa and back 2,400 Pa for reliable operation in harsh conditions.
• Commercial assurances: 12-year product warranty and 30-year linear performance warranty, procured through trusted channels like SolarTraders.
