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
SunEvo Solar is a Chinese manufacturer headquartered in Hefei, Anhui, founded in 2011. The company reports an annual module production capacity of around 7.5 GW and cumulative shipments of over 14 GW across more than 80 countries. SunEvo describes itself as a Tier 1 manufacturer on its own website, citing standard certifications such as UL, TUV, and IEC, but no independent confirmation of BloombergNEF Tier 1 bankability status was found in searches at the time of writing. Tongwei, operating its solar division under the TW Solar brand, is a much older and larger Chinese enterprise founded in 1982 and headquartered in Chengdu, Sichuan. It is a Fortune Global 500 company, holds confirmed BloombergNEF Tier 1 module manufacturer status as of Q1 2025, and operates module production capacity of roughly 90 GW annually alongside over 150 GW of solar cell capacity - making it one of the most vertically integrated PV producers in the world. In terms of institutional scale and verified bankability, Tongwei carries a substantially stronger footprint.
On the product side, SunEvo offers modules spanning PERC, TOPCon, HJT, and back-contact cell technologies, with power ratings up to the 700-750 W range. Its positioning appears aimed primarily at price-sensitive residential and small commercial buyers, and it has a US-facing subsidiary for that market. Tongwei's product lineup centers on its TNC series of N-type TOPCon bifacial modules - including a 770 W variant rated at 24.8% efficiency confirmed by pv-magazine - as well as a THC series of HJT modules developed around its own in-house cell technology. Selected TW Solar models have earned Top Performer recognition in PVEL scorecards, and the bifacial TOPCon range is well suited to both utility-scale ground mounts and large commercial rooftops.
For most buyers in 2025, Tongwei is the more defensible default: its confirmed BloombergNEF Tier 1 status matters for project financing, its vertical integration from polysilicon to module reduces supply-chain risk, and third-party test data backs its efficiency claims. SunEvo is a viable and more accessible option for off-grid, DIY, or small-scale installers where formal bankability requirements are not a factor, but buyers sourcing at scale or seeking financed projects should treat the absence of independent Tier 1 confirmation as a meaningful distinction.
