Bifacial Double Glass Module with Excellent Reliability and Additional Yield

The high-performance module Q.PEAK DUO XL-G10 / BFG is the ideal solution for commercial and utility applications thanks to a combination of its innovative Q.ANTUM DUO-Z technology and cutting-edge cell interconnection. This 1500 V UL/IEC solar module ensures superior yields with up to 490Wp while having a very low LCOE.

All benefits of Q.PEAK DUO XL-G10/BFG

A reliable investment

Double glass module design enables extended lifetime with 12-year product warranty and improved 30-year performance warranty.

Low electricity generation costs

Q.ANTUM DUO Z combines cutting edge cell separation and innovative wiring with Q.ANTUM Technology for higher yield per surface area, lower BOS costs, higher power classes, and an efficiency rate of up to 21.2 %.

Enduring high performance

Long-term yield security with Anti LID Technology, Anti PID Technology, Hot-Spot Protect and Traceable Quality Tra.Q™.

Frame for versatile mounting options

High-tech aluminum alloy frame protects from damage, enables use of a wide range of mounting structures and is certified regarding IEC for high snow (5400 Pa) and wind loads (3000 Pa).

Bifacial energy yield gain of up to 20 %

Bifacial Q.ANTUM solar cells make efficient use of light shining on the module rear-side for radically improved LCOE.

Innovative all-weather technology

Optimal yields, whatever the weather with excellent low-light and temperature behavior.

At least 98% of nominal power during first year. Thereafter max. 0.45% degradation per year. At least 84.95% of nominal power up to 30 years.
Temperature Coefficient

The “temperature coefficient” describes the percentage of power output that is lost by a specific solar panel as the temperature rises above 77°F. It specifies just how heating affects the module power, and provides a number showing how much the module power is reduced if the ambient temperature is increased by one degree Celsius. The lower the temperature coefficient, the better.

Temperature Tolerance

The ranges in “temperature tolerance” indicates expected operating temperature of the PV module. In order words, modules are capable of continuous operation at their rated power with a temperature rise within the specified insulation temperature.
