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

JA Solar JA-JAM54-D41-440MB is a PV module fit for both residential and commercial applications. JA Solar engineers made the Black series durable and efficient while minimizing the amount of useful space required for their operation. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

The use of half-cut cell technology is an additional perk. The solar cells of JA-JAM54-D41-440MB are half the size of those found in standard panels. Major advantages include reduced power consumption, extended life and enhanced efficiency in low-light conditions. The efficiency of this model reaches 22.5% — well above the market’s average. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. JA Solar provides 25 years of product warranty and guarantees that after 30 years, performance will be at 87.4% or more.

High productivity thanks to the most recent developments

This JA Solar panel produces 440 W of power at 22.5 percent efficiency. High levels of energy output are reached by utilizing the most recent innovations in the solar sector. A more efficient panel produces more per square foot and pays for itself sooner.

Exceptional performance in scorching weather

At high working temperatures, a low temperature coefficient equals increased energy generation. Every 1.8°F over 77°F results in a model's efficiency loss of just -0.29 percent.

Quality and reliability

JA-JAM54-D41-440MB is subject to rigorous quality and reliability testing as well as many quality checks throughout the production process. The level of automation in the manufacturing facilities virtually eliminates human error. To guarantee that you receive the finest, REC is committed to quality, safety and dependability.

Reliability and degradation resistance

Slow degradation over the next 30 years is guaranteed by JA Solar. The performance will decrease no more than 2% during the first year and 0.25% annually thereafter. Your modules will retain at least 87.4% of original performance after the 30 years are over. This 440 W JA Solar solar panel also comes with a generous 25-year product warranty.

Certified for the most challenging environmental conditions

JA-JAM54-D41-440MB is resistant to PID, salt, acid and ammonia. It can also withstand up to 5400 Pa mechanical load on the front and 3000 Pa on the back. Such robustness is mainly due to the 1.18" thick Black anodised aluminium frame and a layer of protective glass.

Outstanding all-black design

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