## Summary

Solarwatt is a German manufacturer founded in 1993 and headquartered in Dresden, Germany. The company is a boutique, premium-tier producer rather than a gigawatt-scale mass manufacturer, and its production capacity is modest by Chinese industry standards. Solarwatt has historically been recognized for quality and bankability in European project finance circles, though recent search results do not confirm a current BloombergNEF Tier 1 listing. AKCOME (officially Jiangsu Akcome Science and Technology) was founded in 2006 in Jiangsu, China, listed on the Chinese stock exchange in 2010, employs more than 6,000 people, and operates in over 30 countries. The company has announced plans for an 8.2 GW HJT module facility and currently runs a large-scale factory in Huzhou, Zhejiang. According to independent review sources, AKCOME was removed from the BloombergNEF Tier 1 list in recent quarters, which is a meaningful flag for project financiers. On institutional footprint and manufacturing scale, AKCOME is the larger industrial actor, though Solarwatt carries stronger brand recognition in the European premium residential segment.

Solarwatt's core product line - the Panel vision series - targets quality-conscious residential and light-commercial rooftop buyers in Europe. The company offers both PERC and TOPCon glass-glass modules, with the newer TOPCon range starting at around 420 Wp and backed by a 30-year product and performance warranty guaranteeing 90% residual yield. AKCOME's portfolio is built around HJT cell technology, in which the company has invested since 2012, achieving mass-production cell efficiencies that independent reviewers place among the competitive mid-to-high tier. AKCOME also has an active pilot program in perovskite cells. AKCOME modules are broadly sold across residential, commercial, and utility segments in Asia, Europe, and Australia.

For a typical European residential buyer in 2025 prioritizing long-term warranty confidence and premium build quality, Solarwatt is the more established and lower-risk choice. For buyers seeking competitive HJT technology at scale - particularly in utility or commercial projects where price-per-watt matters more than brand heritage - AKCOME can be viable, but its removal from Tier 1 lists warrants extra due diligence on warranty backstop and financial stability.
