## Summary

Hanersun is a Chinese module manufacturer headquartered in Nanjing, founded in 2015 and rebranded from CSUNPOWER in 2022. The company appears on BloombergNEF's Tier 1 list, runs roughly 5 GW of annual production capacity, and had cumulatively shipped over 16 GW of modules by the end of 2025, though PV Tech's independent bankability ranking rated it CCC+, signalling growing but not yet top-tier financial trust. Heckert Solar, by contrast, is a German manufacturer based in Chemnitz that has operated since 2001, with its first module leaving the line in 2003; it is far smaller in scale, with roughly 800 MW of annual capacity split between its Chemnitz and Langenwetzendorf plants, but it carries a stronger institutional footprint as one of the few surviving European module makers still manufacturing domestically.

Hanersun's product line centers on N-type TOPCon cells in large-format 600W-700W modules aimed at both rooftop and utility-scale ground-mount projects, where cost per watt and high unit power matter most. Heckert Solar produces monocrystalline and polycrystalline modules exclusively in Germany, and in partnership with Fraunhofer ISE developed a 400W module at roughly 20.5 percent efficiency targeted mainly at residential and commercial rooftop use, where domestic origin and supply-chain traceability are the selling points.

For a buyer chasing the lowest installed cost and the highest per-panel wattage, Hanersun is typically the more economical default given its scale and TOPCon technology. Heckert Solar remains the choice for buyers who specifically value European manufacturing and shorter supply chains, accepting a meaningfully higher price per watt in exchange.
