LONGi 540W Solar Panel 144 Cell LR5-72HBD-540M Clearance

LR5-72HBD-540M 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.

The use of half-cut cell technology is an additional perk. The solar cells of LR5-72HBD-540M are half the size of those found in standard panels. Major advantages include reduced power consumption, extended life and enhanced efficiency in low-light conditions. As a result, the panel achieves an impressive efficiency of 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. LONGi provides a 12-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 30 years.

• 144 half-cut PERC cells
• 540 W nameplate capacity
• 21.1% efficiency
• 1500 V DC maximum system voltage
• MC4 connectors
• 12 years of product and 30 years of performance warranty

High efficiency of 21.1 percent

LONGi Hi-MO 5 panels fully use the firm's innovations, which LONGi has received several distinctions for. With PERC technology, more electricity can be produced per square foot of PV modules. As a result, there will be less clamps and racks required during installation. All of which lowers your overall expenses and accelerates the payback period.

Keeping the cool in high temperatures

LR5-72HBD-540M manages to stay efficient even at high temperatures. For every 1.8°F above 77°F, it loses just -0.34% in efficiency, allowing you to make the most of the sunniest hours.

Quality and reliability

LR5-72HBD-540M is subject to rigorous quality and reliability testing as well as many quality checks throughout the production process. The level of automation in the manufacturing facilities virtually eliminates human error. To guarantee that you receive the finest, REC is committed to quality, safety and dependability.

Low degradation for increased longevity

In the first year of service, these panels will lose no more than 2% of their power output. The average yearly power drop from the second to the 30th year will be no more than 0.45%. After 30 years, the modules will retain more than 84.95% of their initial output.

Certified for the most challenging environmental conditions

LR5-72HBD-540M is resistant to PID, salt, acid and ammonia. It can also withstand up to 5400 Pa mechanical load on the front and 2400 Pa on the back. Such robustness is mainly due to the 1.37" thick anodized aluminum frame and a layer of protective glass.
