JA Solar Double Glass
As a leading Tier 1 solar equipment distributor and one-stop B2B solutions provider, we are proud to present a new generation of photovoltaic innovation: JA Solar's N-type bifacial dual-glass modules. Featuring the advanced Deep Blue 4.0 Pro technology architecture-specifically the flagship JAM66D45-640/LB model-this series is engineered to maximize energy density, reduce the Levelized Cost of Electricity (LCOE), and ensure outstanding long-term performance even in extreme environmental conditions.
Whether you are planning utility-scale tracking projects in Europe or East Asia, or managing commercial grid-tied systems, the JA Solar 640W series represents the pinnacle of high-end photovoltaic engineering.
Key Advantages of N-Type Technology
Transitioning from traditional p-type PERC technology to JA Solar n-type modules unlocks substantial financial and operational benefits:
- Elevated Energy Yields: Powered by Bycium+ cell technology, these modules maximize density and minimize recombination losses, achieving a peak efficiency of 23.7%.
- Optimized Performance Warranty: Our n-type double glass bifacial modules 30 year warranty yield guarantees that you secure maximum returns over the system's life cycle. You get a 12-year product warranty and an industry-leading 30-year linear power output warranty.
- Slower Degradation: The bifacial double glass solar panels degradation rate over 30 years is incredibly low. With only 1% degradation in the first year and an ultra-low 0.4% annual degradation thereafter, the system delivers up to 87.4% of its original rated capacity even in year 30.
- Superior Bifaciality: The back-side generation of these bifacial double glass modules captures reflected light from ground surfaces (albedo), turning unused ground reflections into productive energy.

FAQ
Q: Are these modules 100% genuine Tier 1 Solar products, and how do you guarantee traceability?
A: Each module comes with a unique, factory-registered barcode on the frame and embedded under the glass. We provide the original factory test report (Flash Report) matching every barcode in your shipment, as well as the official warranty certificate from JA Solar, ensuring full bankability for your project financiers.
Q: What is the exact power range of the JAM66D45 LB series, and what is the power tolerance?
A: The JAM66D45 LB series spans from 615W to 640W. Specifically, the models available are 615W, 620W, 625W, 630W, 635W, and 640W.
Q: What is the fire rating of these double-glass modules?
A: Safety is a key benefit of the double-glass structure. These modules are certified under UL Type 29 and classified as Class C Fire Performance.
Q: Can we request customized cable lengths?
A: Yes, we can accommodate customized cable lengths and specific premium connector brands upon request.
Q: How can your "One-Stop Solution" lower our project's overall balance-of-system (BOS) and logistics costs?
A: As a comprehensive systems provider, we don't just ship panels. We can match these 640W n-type modules with fully compatible utility-scale string inverters (like Growatt or Sungrow), customized aluminum/steel racking structures designed for 30mm frames, and outdoor DC cabling.
