JA Solar JAM66D46-710/LB Bifacial Glass-Glass Module 710 Wp Deep Blue 4.0 n-type Mono 16-BB – n-type bifacial glass-glass module with 710 Wp
1. Product overview
The JAM66D46-710/LB is an n-type bifacial glass-glass photovoltaic module (Deep Blue 4.0) with a maximum output of 710 Wp. It uses monocrystalline cells in a 16-busbar configuration and is designed for high-voltage stringing and bifacial installations. The module specification includes an improved low-irradiance response and defined temperature coefficients.
2. Strongest advantages for installers
✅ Bifacial energy yield – Bifaciality: 80 % ±5 % (rear-side yield relative to front).
✅ Glass-glass construction – increased mechanical durability and weather resistance (double glass).
✅ Reduced BOS cost & lower LCOE potential – high nominal power (710 Wp) and elevated efficiency (22.9 %) allow fewer modules per system.
✅ Multi-busbar technology – 16-BB cell layout for improved light collection and reduced series resistance.
✅ High mechanical load capacity – front static load 5400 Pa, back static load 2400 Pa.
✅ High system voltage capability – suitable for systems up to 1500 V DC, enabling longer strings.
✅ Installation reliability – IP68 junction box with 3 bypass diodes and industry-standard connectors (QC 4.10-351 / MC4-EVO2A).
✅ Low degradation profile – max. 1 % first-year degradation; 0.4 % annual thereafter.
✅ Glass-glass construction – increased mechanical durability and weather resistance (double glass).
✅ Reduced BOS cost & lower LCOE potential – high nominal power (710 Wp) and elevated efficiency (22.9 %) allow fewer modules per system.
✅ Multi-busbar technology – 16-BB cell layout for improved light collection and reduced series resistance.
✅ High mechanical load capacity – front static load 5400 Pa, back static load 2400 Pa.

4. Technical advantages of the JAM66D46-710/LB
- Designed for utility and large commercial systems where high power per module (710 Wp) and 1500 V compatibility reduce BOS and string counts.
- Bifacial specification (80 % ±5 %) and rear/front data provide measurable additional yield potential in reflective or optimized mounting configurations.
- n-type cell technology and stated improved low-irradiance response reduce light-induced losses and improve diffuse-irradiance performance.
- Glass-glass construction combined with high front/back static load ratings supports long-term mechanical reliability.
- 16-busbar cell architecture reduces series resistance and supports the module’s high STC efficiency.
