## Summary

AEET Energy Group GmbH is a Germany-based photovoltaic wholesale distributor headquartered in Bad Gandersheim, operating as one of the earlier entrants in Europe's solar distribution sector. Rather than a pure-play module manufacturer, AEET functions as a full-service wholesale partner that carries both its own branded modules - covering monocrystalline and thin-film formats - and distributes products from partner brands such as IBC Solar, Mage Solar, and CNPV. No confirmed BloombergNEF Tier 1 listing was found for AEET through available public sources. Resun Solar Energy Co., Ltd., by contrast, is a Chinese module manufacturer founded in 2005 and based in Changzhou, Jiangsu, with a reported annual production capacity of around 5 GW spanning a wide wattage range. Resun holds ISO 9001 and ISO 14001 factory certifications, TUV-verified IEC61215 and IEC61730 module certifications, and a PID-free declaration from PI-Berlin lab. No Tier 1 BloombergNEF confirmation was found for Resun in publicly available sources either. In terms of institutional footprint, Resun carries a more visible manufacturing scale, with documented World Bank project supply relationships across multiple continents.

Resun targets both residential rooftops and utility-scale ground-mount applications. Its current flagship lines incorporate 210 mm large-format wafers with TOPCon cell technology, multi-busbar wiring, and half-cell architecture, pushing peak output to 720 W on the high end. AEET's branded modules cover standard residential and small commercial segments, with monocrystalline products in conventional form factors. AEET also provides installation, planning, and maintenance services alongside module sales, making it more of a regional systems integrator than a volume module supplier.

For a buyer sourcing modules at scale in 2025, Resun Solar offers a more verifiable manufacturing pedigree, broader product range, and documented access to modern TOPCon technology, giving it a practical edge for mid-size commercial or utility projects. AEET may suit buyers in the German-speaking market who value bundled installation services or local distributor relationships over raw panel volume.
