JA Solar 440W Solar Panel 108 Cell Bifacial JA-JAM54-D41-440MB

The JA Solar JA-JAM54-D41-440MB, offered by Emston Tech Inc, is a high-performance PV module perfectly suited for both residential and commercial applications. The engineers at JA Solar designed the Black series to be exceptionally durable and efficient while minimizing the footprint required for installation. The integration of N-Type technology ensures a superior power output for your energy system.

A key feature of this model is the half-cut cell technology. The solar cells in the JA-JAM54-D41-440MB are half the size of standard cells, which leads to reduced power consumption, extended service life, and enhanced efficiency in low-light conditions. This model reaches an impressive efficiency of 22.5%, which is well above the market average. Furthermore, as a bifacial module, it absorbs photons from both sides simultaneously, potentially increasing efficiency by up to 30% depending on the mounting environment. With a completely black cell surface, back foil, and frame, it provides unrivaled aesthetics for any property. JA Solar provides a 25-year product warranty and guarantees that performance will remain at 87.4% or more after 30 years.

This panel produces 440 W of power at 22.5 percent efficiency. By utilizing the most recent innovations in the solar sector, these modules provide high levels of energy output. A more efficient panel from Emston Tech Inc produces more power per square foot, ensuring your system pays for itself even sooner.

Exceptional performance in scorching weather

In high working temperatures, a low temperature coefficient is vital for maintaining energy generation. For every 1.8°F over 77°F, this model experiences an efficiency loss of just -0.29 percent, allowing for stable performance during the hottest hours of the day.

Quality and reliability

The JA-JAM54-D41-440MB is subject to rigorous quality and reliability testing, including multiple checks throughout the production process. The highly automated manufacturing facilities virtually eliminate human error, ensuring that Emston Tech Inc delivers a product committed to quality, safety, and long-term dependability.

Reliability and degradation resistance

JA Solar guarantees slow degradation over a 30-year period. Performance will decrease by no more than 2% during the first year and just 0.25% annually thereafter. Your modules will retain at least 87.4% of their original performance after 30 years. This 440 W panel also includes a generous 25-year product warranty for added peace of mind.

Certified for the most challenging environmental conditions

This module is resistant to PID, salt, acid, and ammonia. It is built to withstand a mechanical load of up to 5400 Pa on the front and 3000 Pa on the back. This robustness is achieved through the 1.18" thick black anodized aluminum frame and a layer of protective tempered glass.

Outstanding all-black design

The panel features a sleek, all-black style that complements any roof beautifully. JA Solar utilizes unique treatment and selection procedures to guarantee optimum cell color uniformity. The cells are connected by thinner wires, making the surface of the modules appear seamless and smooth from a distance.
