Written summary
AEET Energy Group GmbH, founded around 2004 and headquartered in Bad Gandersheim, Germany, is a photovoltaic wholesale distributor and full-service specialist rather than a panel manufacturer in its own right. The company sources modules from leading global producers and supplies them to installers and project developers primarily across the European market. Because AEET does not manufacture panels itself, it holds no BloombergNEF Tier 1 module manufacturer designation and carries no independently verified production-capacity figure of its own. LONGi Solar, by contrast, is a Chinese manufacturer founded in 2000 and headquartered in Xi'an, China, that has grown into one of the world's largest solar producers; the company shipped more than 63 GW of cells and modules in the first nine months of 2025 and has earned BloombergNEF Double Tier 1 status covering both modules and storage. By any institutional measure, LONGi carries the stronger global footprint.
Because AEET operates as a distributor, its product range reflects whichever panel brands it stocks at a given time rather than a proprietary technology roadmap. Its catalog typically covers residential rooftops, commercial installations, and the balcony power-plant segment popular in German-speaking markets. LONGi, by contrast, develops its own cell technologies under the Hi-MO product line. Confirmed 2025 offerings include the Hi-MO 7 using TOPCon cells, the Hi-MO 9 using HPBC 2.0 back-contact technology at up to 670 W, and the Hi-MO S10 using HJT back-contact cells at 25% efficiency aimed at premium residential rooftops. The EcoLife series, combining HJT and back-contact designs, extends the portfolio to utility-scale ground mounts.
For a typical buyer, this is less a brand-versus-brand comparison and more a channel decision. Purchasing through AEET can suit installers in German-speaking markets who want consolidated local logistics and multi-brand flexibility - potentially including LONGi panels within that mix. A buyer who wants a single globally bankable manufacturer with a defined proprietary technology roadmap should engage LONGi directly or through its certified distribution network.
