## Summary

AEET Energy Group GmbH is a Germany-based photovoltaic wholesale and full-service partner headquartered in Bad Gandersheim. The company has operated in the solar sector for many years, distributing modules from major manufacturers while also producing some proprietary polycrystalline and monocrystalline panels under its own brand. AEET maintains a network of over 500 certified specialist partners across Germany, positioning itself as a mid-market European integrator rather than a large-scale module manufacturer; its name does not appear in publicly available BloombergNEF Tier 1 module manufacturer rankings. Sunplus Optimum Inc, operating as Sunplus, is a manufacturer with production bases in Asia, the Americas, and Europe, with its commercial focus directed at the North American market. The company transitioned from an OEM/ODM model to direct brand supply and claims to manufacture under Bloomberg Tier 1 guidelines, though independent confirmation on the official BNEF quarterly list was not found in available sources. By geographic reach and declared production scale, Sunplus has the stronger manufacturer footprint.

Sunplus offers a broad technology portfolio including PERC, TOPCon, HJT, and shingled cell formats with 182mm and 210mm cell sizes, and bifacial dual-glass designs suited to residential, commercial, and utility-scale ground-mount projects. UL and CSA certifications position its modules for US and Canadian installations. AEET's catalog centers on polycrystalline and monocrystalline formats aimed at European residential and small commercial rooftops, with modules carrying a 10-year product warranty and a 25-year performance guarantee - backed by a full-service model that includes system planning, installation, and ongoing support through its German partner network.

For North American buyers in 2025, Sunplus is the more directly relevant option given its US-market certifications, supply chain focus, and multi-technology range. AEET is the stronger fit for European - particularly German - buyers who value a local full-service partner over cutting-edge module innovation. Neither brand competes in the top tier alongside JinkoSolar, LONGi, or Trina Solar, so buyers should confirm bankability and project financing acceptance before committing to large volumes.
