Compare Q-Cells panels on ComparePV." source: "https://comparepv.com/reviews/q-cells" --- # Q-Cells panels, *read off the datasheets* Qcells is a renowned global provider of complete energy solutions, specializing in solar cells and modules, energy storage solutions, downstream project business, and energy retail. The company has a strong heritage dating back to its foundation in Germany and has become a... Everything below is computed from those 89 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Q-Cells does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 1999 - **Headquarters:** Seoul, South Korea - **Annual capacity:** 11.2 GW - **Employees:** 2000+ - **Listed:** NASDAQ: HQCL - **Tier 1 bankable:** Yes (good) Company facts, not datasheet figures. Tier 1 is a financier's bankability list, and says nothing about how a panel performs. ## Key figures | Measure | Value | Note | | --- | --- | --- | | Panels | 89 | models in the database | | Average efficiency | 21.2 % | across the catalogue | | Best efficiency | 23.2 % (good) | their strongest module | | Power range | 335-675 Wp | smallest to largest | | Bifacial share | 39 % | 35 dual-sided models | | Average warranty | 27 years | guaranteed output term | ## 01. The top of the range The leaders of Q-Cells's own catalogue on the two figures a specification sheet leads with. Neither is a verdict: the most efficient module in a range is rarely the one that suits a given roof. ### Most efficient module efficiency | # | Panel | power | efficiency | | --- | --- | --- | --- | | 1 | [Q.TRON M-G3R.12+ / BFG 515](https://comparepv.com/panel/q-cells-q-tron-m-g3r-12-bfg-515) | 515 Wp | 23.2% (good) | | 2 | [Q.TRON XL-G2.3 / BFG 645](https://comparepv.com/panel/q-cells-q-tron-xl-g2-3-bfg-645) | 645 Wp | 23.1% (good) | | 3 | [Q.TRON M-G3R.12+ / BFG 510](https://comparepv.com/panel/q-cells-q-tron-m-g3r-12-bfg-510) | 510 Wp | 22.9% (good) | | 4 | [Q.TRON XL-G2.3 / BFG 640](https://comparepv.com/panel/q-cells-q-tron-xl-g2-3-bfg-640) | 640 Wp | 22.9% (good) | | 5 | [Q.TRON XL-G2.3 / BFG 635](https://comparepv.com/panel/hanwha-q-cells-america-inc-q-tron-xl-g2-3-bfg-635) | 635 Wp | 22.7% (good) | - Q.TRON M-G3R.12+ / BFG 515 - Monocrystalline bifacial - Q.TRON XL-G2.3 / BFG 645 - Monocrystalline bifacial - Q.TRON M-G3R.12+ / BFG 510 - Monocrystalline bifacial - Q.TRON XL-G2.3 / BFG 640 - Monocrystalline bifacial - Q.TRON XL-G2.3 / BFG 635 - Monocrystalline bifacial [Sort the whole catalogue by efficiency](https://comparepv.com/panels/q-cells?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [Q.PEAK DUO ML-G12S.3 / BFG 675](https://comparepv.com/panel/q-cells-q-peak-duo-ml-g12s-3-bfg-675) | 21.7% | 675 Wp | | 2 | [Q.PEAK DUO ML-G12S.3 / BFG 670](https://comparepv.com/panel/q-cells-q-peak-duo-ml-g12s-3-bfg-670) | 21.6% | 670 Wp | | 3 | [Q.PEAK DUO ML-G12S.3 / BFG 665](https://comparepv.com/panel/q-cells-q-peak-duo-ml-g12s-3-bfg-665) | 21.4% | 665 Wp | | 4 | [Q.PEAK DUO ML-G12S.3 / BFG 660](https://comparepv.com/panel/q-cells-q-peak-duo-ml-g12s-3-bfg-660) | 21.2% | 660 Wp | | 5 | [Q.PEAK DUO ML-G12S.3 / BFG 655](https://comparepv.com/panel/q-cells-q-peak-duo-ml-g12s-3-bfg-655) | 21.1% | 655 Wp | - Q.PEAK DUO ML-G12S.3 / BFG 675 - Monocrystalline bifacial - Q.PEAK DUO ML-G12S.3 / BFG 670 - Monocrystalline bifacial - Q.PEAK DUO ML-G12S.3 / BFG 665 - Monocrystalline bifacial - Q.PEAK DUO ML-G12S.3 / BFG 660 - Monocrystalline bifacial - Q.PEAK DUO ML-G12S.3 / BFG 655 - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/q-cells?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 89 modules in the database, counted once each. A power ladder of one module counts as its rungs, which is why a large catalogue is not the same as a wide one.
