Today the company operates manufacturing across South Korea, the United States, and Germany, and is a confirmed Bloomberg Tier 1 module manufacturer. Its US footprint is particularly notable: two facilities in Georgia together represent approximately 8.4 GW of annual module capacity, which industry sources describe as the largest solar manufacturing campus in the Western Hemisphere. Sungrow was founded in Hefei, China in 1997 and built its global reputation as an inverter and energy storage company - BloombergNEF ranked it the world's number-one bankable inverter brand in 2025 with a 100% bankability rating. Sungrow has more recently entered module manufacturing, deploying N-Type TOPCon bifacial panels as part of a vertically integrated portfolio, though its solar panel business remains considerably newer and smaller in scale than its inverter division. On institutional footprint, Q-Cells carries the deeper track record specifically as a panel manufacturer. Q-Cells product families center on the Q.ANTUM NEO line, which uses the company's proprietary passivated-contact cell architecture to reach efficiencies above 22.5%, paired with 25-year product warranties. The brand is most strongly positioned in premium residential rooftop installations in the US and Europe, though it also serves commercial and light utility projects. Sungrow's modules, built around N-Type TOPCon cells with bifacial dual-glass construction, are pitched primarily as part of an end-to-end system combining Sungrow inverters and battery storage. This makes them an appealing option for integrators who already specify Sungrow inverters for commercial or utility-scale ground-mount projects, but the panel-only track record is limited compared to established pure-play module manufacturers. For a typical buyer in 2025 seeking a standalone panel purchase - particularly for residential or commercial rooftops in the US or Europe - Q-Cells is the more straightforward default, given its longer module-specific track record, confirmed Tier 1 status, domestic US manufacturing, and well-documented warranty performance. Sungrow panels are worth considering primarily when the buyer is already building around Sungrow inverters and wants a tightly integrated system from a single vendor. \---LINKS--- \- https://www.solarreviews.com/blog/hanwha-q-cells-solar-panels-complete-review \| Expert Review of Qcells Solar Panels for 2025 - SolarReviews \| review \- https://www.pv-tech.org/sungrow-and-huawei-achieve-aaa-rating-in-new-pv-invertertech-bankability-report/ \| Sungrow and Huawei achieve AAA rating in PV InverterTech bankability report \| article \- https://www.prnewswire.com/news-releases/sungrow-secures-top-rank-again-in-bloombergnefs-2025-inverter-bankability-survey-302703341.html \| Sungrow Secures Top Rank Again in BloombergNEF 2025 Inverter Bankability Survey \| article \- https://www.vicoexport.com/en/62368/sungrow-launches-its-new-line-of-photovoltaic-solar-modules/ \| Sungrow launches new line of photovoltaic solar modules \| article \- https://www.hanwha.com/newsroom/news/press-releases/hanwha-qcells-new-cartersville-factory-set-for-33-gw-of-solar-module-production-per-year.do \| Hanwha Qcells Cartersville factory set for 3.3 GW of solar module production per year \| article Sources: \- \[Expert Review of Qcells Solar Panels for 2025 - SolarReviews\](https://www.solarreviews.com/blog/hanwha-q-cells-solar-panels-complete-review) \- \[Sungrow and Huawei achieve AAA rating in new PV InverterTech bankability report - PV Tech\](https://www.pv-tech.org/sungrow-and-huawei-achieve-aaa-rating-in-new-pv-invertertech-bankability-report/) \- \[Sungrow Secures Top Rank Again in BloombergNEF's 2025 Inverter Bankability Survey\](https://www.prnewswire.com/news-releases/sungrow-secures-top-rank-again-in-bloombergnefs-2025-inverter-bankability-survey-302703341.html) \- \[Sungrow launches new line of photovoltaic solar modules - Vico Export\](https://www.vicoexport.com/en/62368/sungrow-launches-its-new-line-of-photovoltaic-solar-modules/) \- \[Hanwha Qcells Cartersville factory set for 3.3 GW of solar module production per year\](https://www.hanwha.com/newsroom/news/press-releases/hanwha-qcells-new-cartersville-factory-set-for-33-gw-of-solar-module-production-per-year.do) Written by claude-sonnet from the figures above. ## Other comparisons - [Q-Cells vs A.B.
