Founded in 2001, it has grown to a module production capacity of roughly 59 GW as of mid-2025 and was named a Tier 1 PV module supplier by S&P Global Commodity Insights in 2025 - a bankability designation that matters to project financiers and lenders. SolarWorld was a German manufacturer founded in 1998 that at its peak operated one of North America's largest solar factories, in Hillsboro, Oregon. It filed for insolvency in May 2017, briefly re-emerged as SolarWorld Industries GmbH in 2018, then filed a second bankruptcy and ceased manufacturing entirely. On any current institutional measure, Canadian Solar holds the stronger footprint by a wide margin. Canadian Solar's active lineup spans three technology tiers. The HiKu6 family uses PERC cell technology and targets cost-sensitive residential and commercial rooftop buyers. The TOPHiKu6 series upgrades to N-type TOPCon cells for premium residential applications, reaching up to 23% efficiency. The TOPBiHiKu6 line pairs N-type TOPCon with a bifacial design for commercial and utility-scale ground mounts that need maximum energy yield per unit area. SolarWorld no longer has a product roadmap - only new-old-stock and refurbished inventory is available on the secondary market, with no current cell-technology development. For any new installation in 2025, Canadian Solar is the practical default. It is an active Tier 1-rated producer with a multi-GW manufacturing base, a current product range spanning residential through utility segments, and warranty backing from an ongoing corporate entity. SolarWorld panels installed years ago continue to perform in the field, and the brand still carries respect for its German-engineering heritage, but no new modules are entering the market and warranty coverage since 2017 has relied on third-party programs rather than direct manufacturer support - making SolarWorld a viable option only for buyers comfortable with secondary-market sourcing. \---LINKS--- \- https://www.solarreviews.com/blog/canadian-solar-panels-expert-review \| Canadian Solar Panels 2025 Expert Review - SolarReviews \| review \- https://www.pvknowhow.com/news/canadian-solar-tier-1-impressive-4-5-gw-milestone/ \| Canadian Solar named Tier 1 supplier - S&P Global 2025 \| article \- https://pv-magazine-usa.com/2017/05/10/breaking-solarworld-files-for-insolvency/ \| SolarWorld files for insolvency - pv magazine USA \| article \- https://www.energysage.com/solar-panels/solarworld/ \| SolarWorld Solar Panels profile and reviews - EnergySage \| review Sources: \- \[Canadian Solar Panels 2025 Expert Review\](https://www.solarreviews.com/blog/canadian-solar-panels-expert-review) \- \[Canadian Solar Tier 1 milestone - pvknowhow.com\](https://www.pvknowhow.com/news/canadian-solar-tier-1-impressive-4-5-gw-milestone/) \- \[SolarWorld files for insolvency - pv magazine USA\](https://pv-magazine-usa.com/2017/05/10/breaking-solarworld-files-for-insolvency/) \- \[SolarWorld Solar Panels profile - EnergySage\](https://www.energysage.com/solar-panels/solarworld/) Written by claude-sonnet from the figures above. ## Other comparisons - [Canadian Solar vs A.B.
