## Summary

AE Solar is a German manufacturer founded in 2003 in Königsbrunn, Bavaria, and stands as a Bloomberg NEF Tier 1 bankable producer - the first in the industry to receive DIBt certification. With a production capacity exceeding 2 GW and a workforce of 501-1000 employees, it operates on a scale an order of magnitude larger than its counterpart here. The company has manufacturing sites in China, Georgia, and Turkey, sells in over 95 countries, and earned the Kiwa PVEL Top Performer Award in 2025. PolyCrown Solar Tech, by contrast, is a smaller Chinese manufacturer founded in 2014 and based in Ningbo, with a production capacity of just 0.2 GW and a team of 101-200 employees. It holds standard ISO and TUV certifications but does not appear on any Tier 1 bankability list, which limits its appeal for financed projects.

AE Solar's portfolio of 442 panel models is broad and technically advanced: roughly 50% of models use TOPCon cell technology, 64% are bifacial, the maximum output reaches 730 Wp, and the average product warranty is nearly 30 years. This makes it well-suited for utility-scale ground-mount projects, agrivoltaic and vertical installations, and commercial C&I rooftop systems where bankability and long-term performance guarantees are required. PolyCrown offers a narrower lineup of 75 models with only about 19% bifacial coverage, but shows a marginally higher average module efficiency of 21.75% versus 21.34% for AE Solar, and a better average temperature coefficient of -0.294%/°C versus -0.313%/°C - an incremental advantage in hot climates. Its maximum panel output also reaches 730 Wp, and the portfolio leans toward N-type cell technology.

For international buyers - particularly in Europe - AE Solar is the lower-risk choice for any project requiring project finance, insurance, or long-term performance guarantees, given its Tier 1 status, established brand, and 20-plus years of operational history. PolyCrown may be competitive in cash-purchase residential or small commercial installations where price sensitivity is the primary driver and bankability is not a requirement, but buyers should weigh the shorter average warranty period of roughly 26 years and the absence of independent third-party performance recognition against any potential cost savings.
