Search results consistently show it ceased operations, leaving customers without warranty support, and it never appeared on any Tier 1 or BloombergNEF bankability list because it produced no panels of its own. Q-Cells, operating under South Korea's Hanwha Group - a Fortune Global 500 conglomerate - is a vertically integrated manufacturer with origins in German cell technology, now headquartered with facilities across Asia, Europe, and notably in Dalton, Georgia, where it operates one of the largest solar manufacturing complexes in the United States. Q-Cells holds a BloombergNEF Top Tier Class bankability score and was named an S&P Global 2025 Tier 1 Cleantech company. With a reported global module production capacity in the range of 12 GW per year, Q-Cells has a vastly stronger institutional footprint than ENCOR ever had. Because ENCOR was an installer that resold third-party equipment rather than a panel brand, there is no product family to compare directly. Q-Cells offers well-documented residential and commercial series - including the Q.TRON and Q.PEAK lines - built around its proprietary Q.ANTUM NEO cell technology, a TOPCon-based architecture that independent reviews confirm delivers panel efficiencies above 22% in current production models. These panels are aimed at premium residential rooftops, mid-size commercial installations, and increasingly at utility-scale projects through U.S.-made modules, which carry domestic content advantages under the Inflation Reduction Act. For any buyer evaluating these two names in 2025, the comparison is effectively one-sided. ENCOR Solar no longer exists as a going concern, and it was never a panel manufacturer to begin with. Q-Cells is a bankable, globally recognized brand with active warranties, U.S. manufacturing, and a strong service track record. Any customer who was previously served by ENCOR and needs panel replacement or warranty service should contact their financing company or a licensed local installer rather than ENCOR itself. \---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.energysage.com/solar/best-solar-panels-complete-ranking/q-cells-solar-panels-complete-review/ \| Q CELLS Solar Panels: The Complete Review - EnergySage \| review \- https://www.hanwha.com/newsroom/news/press-releases/hanwha-qcells-named-an-s-p-global-2025-tier-1-cleantech-company.do \| Hanwha Qcells named 2025 S&P Global Tier 1 Cleantech company \| article \- https://www.pv-magazine.com/press-releases/q-cells-achieves-top-tier-class-bankability-score-in-latest-bloombergnef-report/ \| Q Cells achieves Top Tier Class bankability score - BloombergNEF \| article \- https://www.solarreviews.com/installers/encor-solar-reviews \| Encor Solar - Out of Business - installer profile \| review Sources: \- \[Expert Review of Qcells Solar Panels for 2025 - SolarReviews\](https://www.solarreviews.com/blog/hanwha-q-cells-solar-panels-complete-review) \- \[Q CELLS Solar Panels: The Complete Review - EnergySage\](https://www.energysage.com/solar/best-solar-panels-complete-ranking/q-cells-solar-panels-complete-review/) \- \[Hanwha Qcells named 2025 S&P Global Tier 1 Cleantech company\](https://www.hanwha.com/newsroom/news/press-releases/hanwha-qcells-named-an-s-p-global-2025-tier-1-cleantech-company.do) \- \[Q Cells achieves Top Tier Class bankability score - BloombergNEF (pv-magazine)\](https://www.pv-magazine.com/press-releases/q-cells-achieves-top-tier-class-bankability-score-in-latest-bloombergnef-report/) \- \[Encor Solar - Out of Business - installer profile - SolarReviews\](https://www.solarreviews.com/installers/encor-solar-reviews) Written by claude-sonnet from the figures above. ## Other comparisons - [ENCOR vs A.B.
