Description

JA Solar DeepBlue 4.0 Pro JAM66D45-600/LB 600W N-Type Bifacial Double Glass Solar Panel

The JA Solar JAM66D45 600W (JAM66D45-600/LB) is an n-type bifacial double glass solar panel from the JA Solar DeepBlue 4.0 Pro JAM66D45 LB series, built for commercial, industrial, and utility-scale projects. It delivers 600W of front-side power at 22.2% module efficiency from 132 (6 × 22) Mono-16BB n-type cells, with 2.0 mm front glass and 2.0 mm back glass.

Inside, the JA Solar JAM66D45 600W uses JA Solar Mono-16BB n-type cells in a bifacial double glass, high-efficiency mono module design. The datasheet highlights higher power generation with a better LCOE, very low LID for an n-type module, a better temperature coefficient, and a better low-irradiance response.

JA Solar JAM66D45 600W High-Efficiency Performance

At Standard Test Conditions the JA Solar JAM66D45 600W is rated at 600W with 22.2% module efficiency and a positive power tolerance of 0 ~ +5 W.

N-Type Bifacial Double Glass Technology

The n-type cells and double glass build of the JA Solar JAM66D45 600W keep degradation low: JA Solar specifies 1% first-year degradation and 0.4% annual degradation over 30 years. The temperature coefficient of Pmax is −0.300 %/°C, so the module keeps more of its output on hot days.

• Temperature Coefficient of Pmax (γ_Pmp): −0.300 %/°C
• Temperature Coefficient of Voc (β_Voc): −0.260 %/°C
• Temperature Coefficient of Isc (α_Isc): +0.046 %/°C
• NOCT: 45 ± 2 °C
• First-year degradation: 1%
• Annual degradation: 0.4% over 30 years

JA Solar JAM66D45 600W Bifacial Energy Gain
