## Summary

AE Solar is a German solar manufacturer headquartered in Königsbrunn, Bavaria, founded in 2003 by brothers Alexander, Victor, and Waldemar Maier. Starting as an installation company, it grew into one of Europe's most recognized module producers, with manufacturing plants in China, Georgia, and Turkey contributing to a combined annual production capacity of approximately 2.5 GW. As of February 2025, AE Solar has achieved BloombergNEF Tier 1 status for the sixteenth consecutive time, and in 2024 BloombergNEF identified it as Europe's sole Tier 1 PV module manufacturer with high bankability - a distinction that substantially simplifies project financing with institutional lenders. Just Solar is a Chinese manufacturer established around 2010-2011 and headquartered in Shanghai, operating factories in Zhejiang province, Macedonia, and Vietnam. The company positions itself as a 2 GW producer and holds TUV (IEC61215/IEC61730), CE, Australian CEC, and UK MCS certifications, but does not appear on the BloombergNEF Tier 1 list, limiting its visibility among institutional investors and project financiers. On the basis of market standing and financial credibility, AE Solar holds a clearly stronger institutional footprint.

AE Solar's portfolio spans residential rooftop, commercial and industrial (C&I), and utility-scale ground-mount segments across more than 95 countries. Its Meteor module series earned a five-star rating in PV Magazine's module test and a Kiwa PVEL Top Performer Award in 2025, providing independent evidence of above-average durability under stress conditions. Just Solar addresses a broadly similar range of applications, from small residential systems to larger commercial projects, with its Macedonian production facility offering some European manufacturing exposure that may appeal to buyers navigating import tariff considerations.

For most international buyers - particularly those requiring bank financing or long-term performance assurance - AE Solar is the stronger default, backed by consistent Tier 1 recognition, third-party lab validation, and a mature European corporate structure. Just Solar is a credible option for cost-sensitive residential or commercial deployments where institutional bankability is not a hard requirement, though the absence of Tier 1 status warrants additional due diligence before committing to larger-scale procurement.
