## Summary

Heliene is a Canadian solar manufacturer founded in 2009 and headquartered in Ontario, with additional manufacturing lines in Minnesota (including a newer 500 MW line in Rogers that brought its US footprint to roughly 1.3 GW) and Florida, giving it a diversified North American production base. Phono Solar, founded around 2007-2008, is headquartered in Nanjing, China, and operates as a subsidiary of SUMEC Group, itself part of the state-owned Sinomach conglomerate, which gives it a large corporate parent and long industrial track record. Both brands appear on BloombergNEF's Tier 1 bankability list, with Phono Solar noting it has held that status since 2014, while Heliene is likewise recognized as a bankable Tier 1 supplier; institutionally, Phono Solar's backing by a major state-linked industrial group gives it somewhat deeper corporate scale, while Heliene's advantage is its "Made in North America" positioning, which matters for buyers targeting US content or domestic manufacturing incentives.

Product-wise, Heliene's catalog spans PERC, N-type and TOPCon cells, with modules from roughly 380W up to 710W, covering everything from residential rooftops to utility-scale ground mounts, and a majority of its lineup is bifacial, suiting large ground-mount projects as well as premium homes. Phono Solar's lineup similarly mixes PERC, TOPCon and some HJT models, including high-wattage bifacial modules exceeding 700W with efficiencies quoted above 23%, and the brand is generally positioned as a value-oriented but technically competitive option for both residential and commercial installs. Both companies report similar average module efficiencies in the low-to-mid 21% range, with Phono Solar's highest-end HJT parts reaching slightly higher peak efficiency figures in some listings.

For a typical 2025 buyer, the choice often comes down to sourcing priorities rather than raw performance: Heliene is the stronger pick where North American manufacturing content, shorter supply chains, or US-based project financing incentives matter, while Phono Solar can be attractive for cost-conscious utility or commercial buyers who value its long-standing Tier 1 track record and broad HJT/TOPCon high-wattage options. On core technology and bankability, the two brands are largely comparable, so the decision is best driven by project location, incentive eligibility, and specific wattage/bifacial requirements rather than a clear overall winner.
