About product

DUO LG7.3 is part of the Q.Peak Duo Series — one of the most recent made by Q CELLS. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. 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. Q CELLS made solar cells in DUO LG7.3 two times smaller than the standard size, thus reducing power loss and improving low-light behavior. As a result, the panel achieves an impressive efficiency of 19.6%. Q CELLS provides an industry-leading 25-year performance warranty and a 12-year product warranty. 

  • 395 W power output
  • 144 half-cut PERC cells
  • 19.6% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 12-year product and 25-year performance warranties

Outstanding productivity integrating the newest advances

This panel's manufacturer offers power output of 395 W at 19.6 percent efficiency. High energy production levels are attained by utilizing the most recent developments in the solar sector. A more productive panel produces more per square foot and pays for itself more quickly.

Excellent performance in adverse weather

Low temperature coefficient means greater energy production at high operating temperatures. DUO LG7.3 loses just 0.35% of efficiency for every 1.8°F above 77°F.

High quality standards

Q CELLS 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.

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 25th year will be no more than 0.54%. After 25 years, the modules will retain more than 85.04% of their initial output.

Certified for the worst environmental conditions

DUO LG7.3 is PID, salt, acid, and ammonia resistant. It can also bear mechanical loads of up to 5400 Pa on the front and 2400 Pa on the back. This durability is mostly owing to the 1.38" thick anodized aluminum frame and a layer of protective glass.
