The Jinko Solar EAGLE® G7X (615-640W) series are N-type bifacial modules designed for maximum energy yield in installations where every square meter counts, ensuring reliable performance year after year. The use of TOPCon cells translates to higher efficiency in practice-especially under suboptimal sunlight and high-temperature conditions, thanks to their low temperature coefficient. Bifacial capability helps capture additional energy from reflected light, effectively improving the energy balance in ground-mounted PV farms, flat roofs, and systems with appropriately optimized albedo.

The EAGLE® G7X also features an enhanced structure for operation in challenging environments-ranging from wind and snow loads to long-term durability-and a long linear warranty, which is crucial for financed projects requiring predictable LCOE. This is an excellent choice for large-scale PV farms, commercial flat roofs, and projects where high energy yield and parameter reliability are top priorities.

What owners get
Best-in-class efficiency in segment

Peak efficiency of 23.69% places the EAGLE® G7X above all three peer comparables: REC Alpha Pro M (22.5%), Suntech Ultra V Pro (22.9%), and MY Solar GOLD HJT (22.61%). Higher power density directly reduces module count and BoS costs per kWp of installed capacity.

Low temperature coefficient - N-type TOPCon

Power temperature coefficient of -0.29%/°C represents ~17% lower thermal losses versus PERC technology (~-0.35%/°C). For installations in temperate and Mediterranean climates, this translates into measurably higher annual energy yield during summer months.

30-year linear power warranty

The manufacturer guarantees a minimum of 87.4% of nameplate power after 30 years of operation - a key LCOE input for bankable projects. The 87.4%/30-year threshold is consistent with best-in-class TOPCon warranty terms and exceeds the 84.8%/25-year standard offered by a portion of comparable modules in this power class.

High mechanical load resistance

Module is certified to withstand 6000 Pa static load on the front side and 5400 Pa on the rear, enabling deployment in high snow- and wind-load zones (Eurocode 1 classes III-IV). This rating is material for utility-scale ground-mount farms and industrial rooftop installations in Alpine or Nordic regions.

Jinko Solar - #1 BNEF Bankability 2025

In the Bloomberg NEF Bankability Report 2025, Jinko Solar is the only manufacturer worldwide to achieve a 100% bankability score - for the 10th consecutive year. With 86 GW of module shipments in 2025, the company ranks first globally by volume. For projects subject to project-finance due diligence, this is a primary risk-mitigation argument when evaluating supplier credibility.

Trade-offs
12-year product warranty - below peer benchmark

The workmanship warranty covers 12 years, while direct competitor REC Alpha Pro M offers 20 years standard (25 years under the ProTrust program with a certified installer). The 8-year gap can be a deciding factor in EPC tenders with long financing horizons or insurance requirements mandating a minimum 15-year product warranty.

Notes from the database
  • Efficiency of 23.7% is 0.9pp above the N-type 600-650W median (22.8%)
  • Power density of 236.9 W/m² packs 9.2 W/m² more into the same footprint vs N-type 600-650W median (227.7 W/m²)
  • At -0.29%/°C, hot weather performance is typical for N-type 600-650W panels
  • At 38.8 kg (6.0 kg above N-type 600-650W median of 32.8 kg), requires checking roof load capacity
  • Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof

About the EAGLE® G7X (615-640W N-type bifacial) series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What warranty does the Jinko Solar EAGLE G7X come with?
The EAGLE G7X carries a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty guaranteeing at least 87.4% of nominal output after 30 years. The long linear power warranty is especially important for commercially financed PV projects where predictable LCOE over the full system lifetime directly affects investment returns.
How does TOPCon technology in the EAGLE G7X compare to standard PERC cells?
The N-type TOPCon cells used in the EAGLE G7X series deliver module efficiency up to 23.69% and a Pmax temperature coefficient of -0.29%/°C, compared to roughly -0.35%/°C for typical P-type PERC modules. This means the EAGLE G7X loses less power on hot days than PERC-based modules, resulting in measurably higher annual energy yield under real-world operating conditions.
How much extra energy does the bifacial design of the Jinko Solar EAGLE G7X actually generate?
The bifacial design of the EAGLE G7X captures light reflected off the ground or rooftop surface in addition to direct front-side irradiance. Depending on the albedo of the surface below the array, bifacial gain typically ranges from 5% to 25% in additional energy output. Light-colored gravel, concrete, or white TPO/PVC roofing membranes on flat roofs produce the highest bifacial gains.
What are the dimensions and weight of the Jinko Solar EAGLE G7X 640W - is it suitable for residential rooftops?
The EAGLE G7X measures 2382×1134×30 mm and weighs approximately 38.8 kg. These are large, heavy modules primarily designed for utility-scale ground-mount arrays and large commercial rooftops where the high per-unit wattage maximizes value. For residential pitched roofs, the size and weight present logistical challenges, and a structural load assessment is recommended before installation.
Can Jinko Solar EAGLE G7X panels handle snow loads and wind in demanding climates?
Yes. The EAGLE G7X is certified to withstand static loads of 6,000 Pa on the front side and 5,400 Pa on the rear, and passes hail impact testing with hailstones up to 55 mm in diameter. These ratings exceed the requirements of most Central European climate zones, making the module suitable for both ground-mount farms and rooftop installations exposed to heavy snow and high winds.
Is Jinko Solar a reliable manufacturer - is the EAGLE G7X from a Tier 1 supplier?
Jinko Solar has been consistently rated as a Tier 1 PV module manufacturer by independent industry analysts, confirming strong financial stability and supply chain continuity. Headquartered in China, Jinko is one of the largest solar module producers in the world by shipped capacity. Tier 1 status is typically required by project finance lenders as part of technical due diligence when assessing long-term technology risk.
