JA Solar 405W Solar Panel 108 Cell JAM54S31-405MR Commercial 864 panels per Container

Among the newest offerings of JA Solar, JAM54S31-405MR is part of the DEEP BLUE 3.0 series. These panels use state-of-the-art technology to achieve high efficiency and dependability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

Another advantage is the half-cut cell technology. JAM54S31-405MR has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. As a result, the panel achieves an impressive efficiency of 20.7%. Novel design solutions allow this panel to look as well as it performs. This model is just 1.18" in depth and is jet black with a sleek finish. The panel's functionality and durability are not affected by its aesthetic appeal. JA Solar provides a 12-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 25 years.

Outstanding productivity integrating the newest advances

This panel's manufacturer offers power output of 405 W at 20.7 percent efficiency. High energy production levels are attained by utilizing the most recent developments in the solar sector. A more productive panel produces more per square foot and pays for itself more quickly.

Excellent performance in adverse weather

Low temperature coefficient means greater energy production at high operating temperatures. JAM54S31-405MR loses just -0.35% of efficiency for every 1.8°F above 77°F.

High quality standards

JA Solar strict manufacturing standards include multiple tests to provide extreme quality assurance. The facilities are highly automated, allowing the company to maintain high standards and keep the level of warranty claims very low.

Reliability and degradation resistance

Slow degradation over the next 25 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 84.8% of original performance after the 25 years are over. This 405 W JA Solar solar panel also comes with a generous 12-year product warranty.

A panel that can handle hail, wind and snow

The 1.18" frame made from anodized aluminum and a layer of protective tempered glass make this module resistant to the foulest of weather. The front side of the modules can resist a 3600 Pa load, and the back side 1600 Pa.

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.
