## Summary

Both Sonnex Energie and AEET Energy Group are German-registered solar companies, though they differ substantially in scale and institutional standing. Sonnex Energie GmbH, headquartered in Germany, claims an annual manufacturing capacity exceeding 2 GW and positions itself as a global PV module and inverter supplier built around German quality standards. AEET Energy Group GmbH, based in Bad Gandersheim, Germany, operates more as a photovoltaic wholesale integrator than a vertically integrated factory - the company sources modules from third-party producers and markets them under its own label alongside planning and installation services. Neither company holds Tier 1 bankable status, which is a meaningful constraint for large project financing, but Sonnex's declared production capacity and dedicated manufacturing infrastructure give it the stronger institutional footprint of the two.

The two lineups occupy very different performance tiers. Sonnex Energie's ten-panel portfolio is built entirely on N-type TOPCon cells, delivering an average efficiency of 21.9% and an average output of 427.5 Wp, peaking at 22.5% and 440 Wp. Half the portfolio is bifacial, making these modules well suited to premium residential rooftops and ground-mounted systems where rear-side irradiance gain is available. A 30-year warranty extends the performance commitment further. AEET's five-panel catalog is a different proposition - average output sits at 190 Wp and average efficiency at 14.9%, topping out at 200 Wp and 15.7%. Cell technology is undisclosed, no bifacial variants are offered, and the warranty runs to 25 years. This compact, modest-efficiency profile targets small commercial or off-grid installations where legacy racking, tight budgets, or low-load applications matter more than peak power density.

For a standard 2025 installation - residential or small commercial - Sonnex Energie is the more compelling choice on nearly every technical dimension: higher efficiency, greater output per panel, modern TOPCon architecture, bifacial availability, and a longer warranty. The efficiency gap alone (21.9% vs. 14.9%) translates to meaningfully fewer panels needed for equivalent system capacity. AEET's lower-wattage modules fill a genuine niche in legacy or compact-format retrofit scenarios, but for general-purpose new builds, Sonnex presents the stronger value proposition. The main caveat for both brands is the absence of Tier 1 bankable status, which may complicate institutional project financing and should be weighed carefully by commercial buyers.
