JA Solar 545W Solar Panel 144 Cell Bifacial JAM72D30-545/MB

JAM72D30-545/MB is part of the DeepBlue 3.0 series — one of the most popular product lines by JA Solar. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. 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 144 cells is only half the size of a traditional solar cell. This grants JAM72D30-545/MB lower resistive losses and better shade tolerance. Not surprisingly, the efficiency of this module is quite high – 21.1%. 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 paid as much attention to durability as they did to performance. JAM72D30-545/MB is guaranteed to retain at least 84.95% of output after 30 years. Product warranty for this panel lasts 12 years.

Great productivity through the latest innovations

This JA Solar panel provides 545 W of power at 21.1% efficiency. High energy production levels are achieved through the usage of the latest advances in the solar industry, including PERC technology and state-of-the-art antireflective coating. An efficient panel yields more per square foot and pays for itself faster.

Keeping cool in high temperatures

Even under extreme heat, JAM72D30-545/MB maintains high efficiency. You may take advantage of the sunniest hours because it loses just -0.35% of efficiency for every 1.8°F over 77°F.

High-quality standards

JA Solar's stringent production requirements include various tests to guarantee high quality. The facilities are highly automated, allowing the manufacturer to maintain high standards while keeping warranty claims to a minimum.

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 0.45% annually thereafter. Your modules will retain at least 84.95% of their original performance after 30 years. This 545 W JA Solar solar panel also comes with a generous 12-year product warranty.

Enhanced frame design

JAM72D30-545/MB's design makes it ideal for residential and commercial rooftops. Strong 1.38" frame made from anodized aluminum increases durability and strength. The model can support a heavy snow load up to 5400 Pa. The back of the panel can handle 2400 Pa, ensuring that your system will survive the strongest of winds.
