LONGi 400W Solar Panel 108 Cells LR5-54HABB-400M Container 792 panels

LR5-54HABB-400M is a model that uses many 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. LONGi made solar cells in LR5-54HABB-400M two times smaller than the standard size, thus reducing power loss and improving low-light behavior. At 20.5% efficiency, LR5-54HABB-400M offers surprising performance for its weight and size. 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. The cell surface, back foil, and frame are completely black, giving the model unrivaled aesthetics. LONGi paid as much attention to durability as they did to performance. LR5-54HABB-400M is guaranteed to retain at least 84.95% of output after 30 years. The product warranty for this panel lasts 25 years.

• 400 W power output
• 108 half-cut PERC cells
• 20.5% efficiency
• 1500 V DC maximum system voltage
• MC4-compatible connectors
• 25-year product and 30-year performance warranties

Higher efficiency of up to 20.5%

LR5-54HABB-400M guarantees the highest power output. PERC technology and potent antireflective coating result in 20.5% module efficiency. This is significantly higher than average, which will result in substantial extra savings over the years of operation.

Exceptional performance in hot temperatures

A low temperature coefficient provides more energy output at high working temperatures. LR5-54HABB-400M loses just -0.34 percent efficiency for every 1.8°F over 77°F.

High quality standards

LONGi 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

LONGi guarantees limited degradation over the ensuing 30 years. The performance will only degrade by a maximum of 2% the first year, and then only by a maximum of 0.45% yearly after that. After the 30 years are over, your modules will still show at least 84.95% of nominal capacity. A substantial 25-year product warranty is also included with this 400 W LONGi solar panel.

Certified for the most extreme environmental conditions

PID, salt, acid and ammonia cannot harm LR5-54HABB-400M. 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 1.18" thick aluminum alloy frame are the primary reasons for its toughness.

Stunning black aesthetics

The sleek, all-black aesthetics of the panel will complement any rooftop. By using a variety of treatments and selection criteria, the producer guarantees high quality cell color. Engineers at LONGi employ smaller gauge wires to link the cells together, creating a seamless appearance.
