Performance & Design Advantages

1. High power density (710W): reduces the number of modules required, lowers mounting and balance-of-system (BOS) costs, and is ideal for constrained roof or ground areas.
2. Excellent conversion efficiency (22.9%): generates more energy per m² vs lower-efficiency modules — beneficial for both rooftop and utility applications.
3. Optimized thermal behavior: competitive temperature coefficients help limit power loss in hot operating conditions, improving year-round energy yield.
4. Positive power tolerance: guaranteed output at or above rated power ensures stronger first-year production estimates.
5. Robust electrical characteristics: balanced Vmp / Imp values make string design straightforward and compatible with modern string and central inverters.

Typical Applications

• Residential rooftops aiming to maximize output with limited roof area
• Commercial and industrial rooftop installations
• Large ground-mounted and utility-scale PV farms where BOS savings matter
• Hybrid systems paired with battery storage and inverters for backup or self-consumption

Installation & Compatibility Notes

• Verify inverter MPPT and Voc limits when designing strings — the module Voc (48.60 V) and system voltage influence string size.
• BIFACIAL / rear-side gain (if applicable) depends on site albedo — higher reflectance (white gravel, concrete, snow) increases rear-side contribution.
• Use appropriate mounting hardware and follow torque specs; consult the mechanical datasheet for wind and snow load ratings.
• Consider temperature derating and local irradiance when modeling expected energy output.

Why Choose JAM66D46-710?

For projects that require high output per module and lower installed cost per watt, the JAM66D46-710/LB offers an excellent balance of high rated power, strong conversion efficiency and stable thermal performance. It is particularly effective for roof-constrained installations and large-scale arrays seeking BOS savings and higher energy yield.

Note: Data above are measured under Standard Test Conditions (STC). Actual system production will vary with site irradiance, temperature, shading and system design. Always consult the full module datasheet and a qualified engineer for final system design and warranty details.
