## Summary

Heckert Solar is a German manufacturer headquartered in Chemnitz, founded in 2001, producing entirely in Germany across plants in Chemnitz and Langenwetzendorf with a nominal capacity of roughly 0.8 to 0.9 GWp per year. It does not appear on BloombergNEF's Tier 1 list, but it positions itself around Made-in-Germany provenance, EU supply-chain traceability, and long standing in export markets, including Poland where it sells through authorized distributors. Sunova, by contrast, is a Chinese manufacturer confirmed as a BNEF Tier 1 module maker, operating at a much larger scale, with reported module capacity moving from roughly 4.2 GW toward 5.5 GW across factories in China and Vietnam, plus a newer 9 GW cell facility in Sichuan. On institutional footprint and manufacturing scale, Sunova clearly outweighs Heckert Solar, while Heckert compensates with regional manufacturing credentials that some European buyers value.

Heckert Solar's product line centers on the ZEUS series using N-type TOPCon and newer back-contact cells, with the flagship ZEUS 3.0+ reaching up to 490 W and around 24.5 percent module efficiency, aimed primarily at residential rooftops and smaller commercial jobs, with ZEUS 2.1 and 2.2 variants for larger C&I installations. Sunova spans a wider power range, from about 400 W up to over 700 W, mixing PERC, N-type, and TOPCon technology through its Thor series, with bifacial modules marketed for both utility-scale ground-mount plants and lighter panels suited to residential and space-constrained roofs.

For a typical buyer, the choice comes down to priorities rather than a clear quality gap: Heckert Solar suits projects where European origin and shorter supply chains matter, while Sunova tends to offer more competitive pricing and stronger bankability for larger, financed projects thanks to its Tier 1 status. Since both brands field credible TOPCon based products, for an average rooftop installation the practical differences are relatively modest.
