AEET vs Just Solar - solar panel manufacturer comparison

AEET Energy Group GmbH is a Germany-based company with roots in photovoltaic wholesale and project development. Rather than operating as a vertically integrated panel manufacturer, AEET functions primarily as a procurement and distribution partner, sourcing modules from leading producers and supplying large-scale commercial and industrial projects across Europe. Because it sits upstream from direct manufacturing, it does not appear on the BloombergNEF Tier 1 module manufacturer list, and no independently verified annual production capacity figures are publicly available. Just Solar Group Limited - trading as Shanghai Just Solar Co., Ltd. - is a Chinese manufacturer headquartered in Shanghai with cell and module production based in Zhejiang province. The company reports roughly 1 GW of vertically integrated capacity and holds standard third-party certifications including TUV IEC 61215 and IEC 61730, CE marking, Australian CEC approval, and UK MCS recognition. In terms of institutional footprint, AEET carries the weight of a well-networked European distributor, while Just Solar represents a mid-tier Chinese manufacturer with certified but sub-Tier-1 standing.

AEET's product offering is oriented around brokering modules from established brands for commercial and utility-scale customers, making it more of a channel than a label in its own right. Just Solar targets a broad mix of commercial, industrial, rural, and residential segments with its own branded modules. No WebSearch results confirmed the dominant cell technology for either brand with precision, so technology claims are omitted here. Just Solar's publicly stated 25-year warranty is consistent with mid-market Chinese manufacturers.

For a buyer evaluating these two in 2025, the choice is less a direct product-to-product comparison and more a question of procurement model. A buyer seeking a branded, certified panel with a direct manufacturer relationship and consistent product lineage would lean toward Just Solar, while AEET is better approached as a wholesale sourcing partner when flexibility across multiple brands matters more than single-label consistency.
