JS Solar vs AEET - solar panel manufacturer comparison

AEET Energy Group GmbH is a German photovoltaic wholesale distributor headquartered in Bad Gandersheim, Germany. Rather than manufacturing panels itself, AEET operates as a full-service channel partner, sourcing modules from leading producers and selling them under its own brand through a network of more than 500 certified specialist partners across Germany. Its products carry TÜV Rheinland certification and come with a performance guarantee of up to 25 years. Because AEET functions as a reseller rather than an original manufacturer, it does not appear on BloombergNEF Tier 1 bankability lists, which rank vertically integrated producers by module shipment volume. JS Solar - formally Jiangsu Jinshang New Energy Technology Co., Ltd., founded in 2004 and headquartered in Yixing, Jiangsu Province, China - is an actual manufacturer, with production bases across eastern China and reported annual exports of around 2 GW of modules and 2 GW of cells and wafers. JS Solar therefore carries a significantly larger institutional and production footprint.

JS Solar's catalog spans solar cells, standard modules, photovoltaic inverters, and energy storage systems targeting both residential rooftop and commercial or industrial buyers. Its panels hold IEC 61215, IEC 61730, CE, RoHS, and MCS certifications, placing them within reach of European and UK project finance requirements. The top-efficiency model in its lineup reaches 22.4 percent, broadly in line with mid-tier n-type offerings, though no independent source confirmed whether that figure comes from a TOPCon or PERC cell platform. AEET's module offering covers both monocrystalline and multicrystalline options but relies on upstream supplier choices rather than proprietary cell technology, making it better suited to small German installers who value a single point of contact for modules, mounting hardware, and inverters.

For a buyer financing a larger project in 2025, JS Solar is the more straightforward choice - it is a traceable, export-scale manufacturer with standard certifications. AEET is better understood as a distribution service for the German market rather than a brand to benchmark on panel-level metrics; the underlying module quality depends entirely on which upstream factory it sources from at a given time.
