AKCOME vs Viessmann - solar panel manufacturer comparison

AKCOME is a Chinese photovoltaic manufacturer headquartered in Zhejiang province, founded in the mid-2000s and focused primarily on solar modules and mounting systems. At its peak the company reported an annual module production capacity of around 3.8 GW and appeared on BloombergNEF Tier 1 bankability lists through early 2024. However, its position has since collapsed: a subsidiary entered court-supervised bankruptcy reorganization in July 2024 after reporting substantial net losses every year since 2019, and the Shenzhen Stock Exchange terminated AKCOME's listing in August 2024. Viessmann, by contrast, is a German climate-technology group founded in 1917, now operating as Viessmann Climate Solutions under Carrier Global Corporation. Its photovoltaic business is a smaller, integrated part of a much larger heating and energy portfolio, and while it holds the EUPD Top Brand PV seal in Germany, it does not appear on BloombergNEF Tier 1 module manufacturer lists as a volume producer. On institutional footprint and financial stability, Viessmann today is the substantially stronger choice.

The two manufacturers serve different use cases and market segments. AKCOME built its volume around mainstream mono-crystalline modules aimed at commercial and utility-scale projects, and search results confirm high-wattage modules (in the 655-700 W range) as part of its catalog. Viessmann's photovoltaic offering centers on its Vitovolt residential product family - most notably the Vitovolt 300 and the newer Vitovolt 300-DG, the latter using bifacial N-type TOPCon double-glass cell technology - designed to integrate seamlessly with the company's heat pumps, inverters, and energy storage systems. Viessmann's approach is thus best described as a premium whole-home energy system for European residential buyers rather than a standalone high-volume module supplier.

For a typical buyer in 2025, Viessmann is the more sensible default if the installation is residential, European, and benefits from bundled heat-pump or storage integration. AKCOME's financial collapse makes it an impractical option regardless of panel specifications, as long-term warranty support and supply continuity are genuinely uncertain. Buyers who previously specified AKCOME for cost-driven commercial projects should treat the brand as effectively unavailable and source from an active BloombergNEF Tier 1 manufacturer instead.
