An expansive (perhaps daunting) solar module range, researching the QCells Q.PEAK DUO-G10 can be simplified as a single module type when the fundamental elements remain tightly similar between models. Plus (+) variants affect warranty length only, a portion of all warranty considerations. ML and XL models affect dimensions and, in turn, power output, yet efficiency remains almost identical. Once stripped back to the intrinsic details, a range that incorporates seven module variants is effectively one, the Q.PEAK DUO-G10 (10th Generation) by QCells.
Model:
QCells Q.PEAK DUO-G10.
Variants:
Monofacial.
- DUO-G10/+ (120-cell); 360-380 W.
- DUO ML-G10/+ (132-cell); 395-415 W.
- DUO BLK ML-G10/+ (132-cell); 385-405 W.
- DUO XL-G10 (156-cell); 475-495 W.
Bifacial.
- DUO XL-G10/BFG (156-cell); 475-490 W.
TLDR:
QCells seeks to tick the boxes of many investors by introducing a plethora of options under the Q.PEAK DUO-G10 umbrella. Fundamentally, all G10 models incorporate an M6 wafer design (G9 – M4 wafer, 161.7mm) further enhancing efficiency in line with the global market shift of improved power density.
Features:
- M6 wafer (166mm), half-cell Q.ANTUM DUO Z (zero gap) monocrystalline.
- Monofacial & bifacial options.
- Advanced multi-busbar design.
- Residential and industry designed module options.
