## Summary

AE Solar is a German manufacturer founded in 2003 and headquartered in Gersthofen, Germany, holding Bloomberg NEF Tier 1 bankable status and operating a production capacity exceeding 2 GW across factories in China, Georgia, and Turkey, with a large-scale 10 GW facility planned in Romania. The company distributes its modules in over 95 countries and has built a strong independent quality record, earning Kiwa PVEL Top Performer recognition in both 2023 and 2025 and becoming in 2025 the first DIBt-certified Tier 1 PV module manufacturer in the industry. SunKean, by contrast, is a China-based manufacturer founded in 2013 with over 200 employees whose roots lie primarily in solar cable and connector manufacturing; the company does not hold a Tier 1 bankability rating and maintains a considerably smaller presence in global PV module markets.

AE Solar's module portfolio spans 442 panels with a peak output of 730 Wp and a maximum efficiency of 24.43%, with TOPCon technology accounting for nearly 50% of its lineup and 63.8% of modules being bifacial. This combination of Tier 1 status, certified quality, and product breadth makes AE Solar well suited for residential rooftop installs, commercial C&I projects, and utility-scale ground-mount systems where bankability and long-term warranty assurance are decisive factors. SunKean's more focused 57-panel portfolio reaches up to 700 Wp and 23.52% peak efficiency, but differentiates itself with a higher bifacial share of 77.2% and a slightly better temperature coefficient of -0.300 %/°C compared to -0.313 %/°C for AE Solar, which translates to marginally lower power losses under elevated operating temperatures.

For international buyers choosing between the two, AE Solar is the lower-risk option for bankable projects. Its Tier 1 certification, two decades of operational history, and established European service network reduce financial and technical risk for investors and lenders alike. SunKean may appeal in cost-sensitive or bifacial-yield-focused applications, but its absence from Tier 1 lists and limited independent review history make thorough due diligence essential before committing to larger or project-financed installations.
