Catalogue against catalogue
An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary
Sonnen is a German energy storage brand founded in 2010 in Wildpoldsried, Bavaria, and acquired by Shell in 2019. It is well established as a residential and small-commercial battery storage specialist but does not manufacture photovoltaic modules and holds no Tier 1 standing with BloombergNEF in the PV panel space. Its entire product identity is built around the sonnenBatterie line and behind-the-meter grid services. Trina Solar, by contrast, is one of the world's largest PV module manufacturers, founded in 1997 and headquartered in Changzhou, Jiangsu Province, China. The company has shipped more than 205 GW of modules globally, confirmed BloombergNEF Tier 1 bankability status in Q1 2025, and operated module production capacity approaching 95 GW annually as of late 2023, with expansion plans targeting 120 GW. In terms of global institutional footprint, Trina Solar is the unambiguously dominant presence in the solar manufacturing landscape.
Trina Solar's portfolio spans residential rooftop, commercial and industrial (C&I), and large-scale utility ground-mount segments. Its current flagship products are built on n-type TOPCon cell technology, with modules reaching 760 W output and 24.5% efficiency in mass production as reported by PV Magazine in December 2024. The company has achieved Top Performer status in PVEL module reliability scorecard testing for eleven consecutive years and has set multiple world efficiency records in cell research. Sonnen offers no photovoltaic module products of any kind; its role in a solar installation is as a storage complement, not a generating component.
For any buyer evaluating these two brands specifically as solar panel suppliers, Trina Solar is the only meaningful option. The two companies are not interchangeable - they occupy entirely different roles in the renewable energy value chain. A well-designed residential system could reasonably pair Trina Solar modules with a Sonnen battery if smart-grid and virtual power plant features are priorities for the end customer. Assessed purely as PV panel manufacturers, however, this comparison is one-sided by definition.
