## Summary

Emona Connect is a French specialist firm based in Biarritz, Nouvelle-Aquitaine, operating in a narrow niche: supplying custom-made replacement PV modules for O&M companies, solar asset managers, and power-plant operators, primarily across Western and Southern Europe. Its model is not that of a mass-volume manufacturer but of a bespoke intermediary that sources or produces replacement panels - often in legacy wattage classes - to keep aging fleets operational. No BloombergNEF Tier 1 listing or bankability rating has been publicly attributed to the company, and disclosed production volumes are not available in industry databases. Q-Cells, now operating globally as Hanwha Q CELLS under South Korea's Hanwha Group, stands at the opposite end of the scale: it holds confirmed BloombergNEF Tier 1 status, maintains module production capacity reported at over 11 GW annually, and operates what is described as the largest solar manufacturing facility in the Western Hemisphere in Georgia, USA. On institutional footprint, Q-Cells is decisively the larger and more bankable entity.

The two brands serve almost entirely different use cases. Emona Connect targets the asset-management and maintenance segment, offering custom framed or unframed mono- and polycrystalline panels - including legacy wattage classes around 215 W to 340 W - with IEC certification and a 10-year product warranty. Its value proposition is continuity and compatibility for existing installations, not leading-edge efficiency. Q-Cells addresses the full spectrum from premium residential rooftops to utility-scale ground mounts. Its Q.ANTUM NEO series uses N-type TOPCon cell architecture, with independently reviewed efficiency ratings above 22%, a temperature coefficient as low as -0.29%/degC, and a 25-year product warranty, making it well-suited to both performance-sensitive homeowners and project developers seeking bankable components.

For any buyer planning a new installation in 2025 - residential, commercial, or utility - Q-Cells is the relevant choice: it is a Tier 1-rated, high-volume manufacturer with verified performance data and strong warranty terms. Emona Connect fills a genuinely different role and is best evaluated when the specific need is sourcing replacement or custom-sized panels for an existing plant rather than deploying new capacity.
