## Summary

Q-SUN Solar, operating under Q-SUN Anhui Co., Ltd, is a Chinese photovoltaic manufacturer founded in 2014 and headquartered in Chuzhou, Anhui province, with additional production sites in Yancheng, Oman, and Bulgaria. The company reports an annual manufacturing capacity approaching 8 GW. Its BloombergNEF Tier 1 bankability status has not been confirmed in publicly available Q1-Q2 2025 reporting, placing it among mid-scale Chinese producers that have strong volume but limited institutional lender recognition. AEET Energy Group GmbH is a German photovoltaic wholesale specialist based in Bad Gandersheim, Lower Saxony, active in the European solar market for many years. Unlike Q-SUN, AEET functions primarily as a distributor and full-service integrator - carrying both own-branded modules and products from third-party suppliers - rather than a large-scale module manufacturer in its own right. On raw production footprint, Q-SUN is the more prominent name in international module supply chains.

Q-SUN's published portfolio addresses both residential and utility segments. Its Mercury Series uses TOPCon cell technology with rated outputs from roughly 400 W to over 700 W, targeting utility-scale and large commercial ground mounts, while the Onyx and Qrystal full-black ranges serve premium residential rooftops where panel aesthetics are a priority. AEET's own-label module catalog, as listed in third-party directories, covers more modest wattage classes - monocrystalline and polycrystalline options suited to small commercial and residential retrofit jobs - with the company placing greater emphasis on planning, installation, and after-sales maintenance services than on cell technology leadership.

For buyers selecting modules on production scale, modern cell architecture, and supply continuity, Q-SUN is the stronger candidate in 2025, especially for mid-size commercial or utility projects. AEET is better understood as a regional European service partner for customers in Germany and neighboring markets who value turnkey installation and localized support alongside module supply. The two serve meaningfully different buyer profiles and are not directly interchangeable.
