## Summary

GoodWe is a Chinese manufacturer headquartered in Suzhou, Jiangsu Province, founded in 2010. The company built its reputation almost entirely on power inverters: BloombergNEF and S&P Global Commodity Insights both recognise it as a Tier 1 inverter supplier, and its inverter production capacity stands at roughly 35 GW per year with more than 100 GW of cumulative global installations. GoodWe does market a solar module line - most notably the Polaris Series featuring TOPCon bifacial cells - but panels remain a secondary offering next to its inverter and storage business. Q CELLS traces its origins to Germany, where it was founded in 1999; it is now the solar division of South Korean conglomerate Hanwha, operating as Hanwha Q CELLS. The company carries BloombergNEF Tier 1 status as a panel manufacturer and has a global module production capacity of around 11 GW per year. Its US footprint is particularly significant: factories in Dalton and Cartersville, Georgia combine for up to 8.4 GW of planned annual module output, making Hanwha the largest crystalline-silicon panel producer in the Western Hemisphere. On institutional scale and dedicated panel manufacturing depth, Q CELLS holds the stronger position.

Q CELLS' core residential and light-commercial product, the Q.TRON line built on the company's Q.ANTUM NEO platform - a TOPCon-derived cell architecture - reaches efficiencies above 22.5% and carries a 25-year product warranty, pricing roughly 15-20% below ultra-premium brands such as Maxeon. SolarReviews ranked Q CELLS third among all panel manufacturers for 2025. GoodWe's Polaris modules use standard TOPCon cells in a bifacial format, making them suitable for carports, flat-to-pitched roof retrofits, and smaller commercial arrays, but independent long-term reliability data on GoodWe panels is far thinner than for Q CELLS, whose modules have been tested in the field for over a decade.

For a buyer choosing solar panels specifically in 2025, Q CELLS is the clearer default. It offers a mature, well-documented TOPCon product family backed by a large, financially stable parent, a meaningful US manufacturing presence, and strong third-party review coverage. GoodWe is worth considering when the purchase centres on an inverter-plus-panel system from a single vendor, but buyers focused purely on panel performance and warranty depth will find Q CELLS the more purpose-built choice.
