JA Solar 545W Solar Panel 144 Cell Bifacial JA-JAM72-D30-545MB Commercial 589 panels per Container (Truckload)

JA-JAM72-D30 is a model that uses a number of technologies to bring durability and performance to the next level. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

Half-cut cell technology adds a few more percent to the overall performance, making this model a great example of efficiency. JA Solar made solar cells in JA-JAM72-D30 two times smaller than the standard size, thus reducing power loss and improving low-light behavior. 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 provides 12 years of product warranty and guarantees that after 30 years, performance will be at 84.95% or more.

• 545 W power output
• 144 half-cut PERC cells
• 21.1% efficiency
• 1500 V DC maximum system voltage
• MC4-EVO2 connectors
• 12-year product and 30-year performance warranties

More power and efficiency

An already high efficiency of 21.1% 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, JA-JAM72-D30 outputs 545 W of power.

Improved efficiency at high temperatures

Greater energy as temperature rises is a mark of a good temperature coefficient. Your panel's efficiency will drop by just -0.35% for every 1.8°F increase over 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

JA Solar guarantees slow deterioration over the next 30 years. The performance will decline by no more than 2% during the first year and then by no more than 0.45% every year after that. After the 30 years are over, your modules will retain at least 84.95% of their original performance. This 545 W JA Solar solar panel also comes with a substantial 12-year product warranty.

Certified for the most extreme environmental conditions

PID, salt, acid and ammonia cannot harm JA-JAM72-D30. Furthermore, it has a mechanical load resistance of up to 5400 Pa in the front and 2400 Pa in the back. A layer of protective glass and 1.38" thick aluminum alloy frame are the primary reasons for its toughness.
