JA Solar 550W Solar Panel 144 Cell Bifacial JAM72D30-550/MB

JAM72-D30 is a model that uses a number of technologies to bring durability and performance to the next level. This panel takes full advantage of the Passivated Emitter Rear Contact (PERC) technology that allows it to capture up to 12% more energy. All thanks to a reflective layer on the back. This design maximizes the number of photons absorbed by solar cells.

To further boost the performance, JA Solar employs half-cut cell technology. Each of the panel’s 44 cells is only half the size of a traditional solar cell. This grants JAM72-D30 lower resistive losses and better shade tolerance. The efficiency of this model reaches 21.2% — 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. JA Solar provides a 12-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 30 years.

• 44 half-cut PERC cells
• 550 W nameplate capacity
• 21.2% efficiency
• 1500 V DC maximum system voltage
• MC4 connectors
• 12 years of product and 30 years of performance warranty

More power and efficiency

An already high efficiency of 21.2% is further enhanced by PERC technology. By adding a solid PID resistance and special glass lamination on top, the manufacturer ended up with an efficient and very durable model. Under standard test conditions, JAM72-D30 outputs 550 W of power.

Exceptional performance in hot temperatures

A low temperature coefficient provides more energy output at high working temperatures. JAM72-D30 loses just -0.35 percent efficiency for every 1.8°F over 77°F.

Quality and reliability

JAM72-D30 undergoes various quality checks during the production process and is subjected to serious quality and reliability testing. Manufacturing facilities are highly automated, removing the possibility of human errors. JA Solar is committed to quality, safety, and dependability to ensure you get the finest.

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 85.24% of original performance after the 30 years are over. This 550 W JA Solar solar panel also comes with a generous 12-year product warranty.

A panel that can handle hail, wind and snow

The 1.38" frame made from anodized aluminum alloy 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 5400 Pa load, and the back side 2400 Pa.
