Q.PEAK-G4.1 Enduring high performance

Q.PEAK-G4.1 300-320 Advanced performance in a highly attractive package

The Q.PEAK-G4.1 is a monocrystalline solar module with performance classes up to 320 Wp and an efficiency of 18.9 %. Q.PEAK-G4.1 solar modules offer higher yields over smaller surface areas. This is made possible by the new Q.ANTUM generation of Q CELLS module architecture. The front surface of the Q.PEAK-G4.1 is completely black and enhances the visual appearance of even the most exclusive private house system.

The Q CELLS Anti LID Technology eliminates light induced degradation (LID), which can greatly reduce system performance, almost completely. Other conventional monocrystalline solar cells will lose much of their initial performance, once exposed to sunlight. With Q.PEAK-G4.1 this is not the case, thanks to Anti LID Technology.

The technology in detail

Q.ANTUM The power boost for your solar panels

We developed Q.ANTUM technology to maximise the efficiency of conventional solar cells. We guarantee high performances under real conditions, in winter or summer and under brilliant sunshine or cloudy skies. Solar cells with the Q.ANTUM technology achieve maximum efficiencies from mass production with a world record 19.5 %. This has been independently confirmed by the Fraunhofer Institute for Solar Energy Systems ISE.

Discover how it works

Overview of the benefits of Q CELLS solar panels

Q.ANTUM technology: Low levelised cost of electricity (LCOE)

Higher yield per surface area, lower BOS costs, higher power classes, and an efficiency rate of up to 19.5%.

Innovative all-weather technology

Optimal yields, whatever the weather. Q.PEAK-G4.1 solar panels are characterised by excellent low-light and temperature behaviour for optimised outputs.

Enduring high performance

Long-term yield security for your Q CELLS solar panels with Anti PID Technology, Hot-Spot Protect and Traceable Quality Tra.Q™.

Extreme weather rating

High-tech aluminium alloy frame, certified for high snow (5400Pa) and wind loads (4000Pa).

Maximum cost reductions

Up to 10 % less logistics costs due to higher solar panel capacity per transport box.

A reliable investment

Q CELLS solar panels have a 12-year product warranty and 25-year linear performance warranty.
