## Summary

Solplanet is a brand of AISWEI Technology, a Chinese company headquartered in Shanghai that traces its origins to 2007 as a former subsidiary of SMA Solar. AISWEI built its reputation primarily as an inverter manufacturer, and the Solplanet brand today covers a broad ecosystem including single-phase and three-phase string inverters, hybrid storage systems, EV chargers, and solar modules. The company has received a bankability review from DNV confirming that its manufacturing processes meet international standards, but Solplanet does not appear on the BloombergNEF Tier 1 solar module manufacturer list. Trina Solar represents a substantially different scale: founded in 1997 in Changzhou, China, it ranks among the world's top five module producers with annual manufacturing capacity exceeding 80 GW. Trina has held BloombergNEF Tier 1 status for over a decade and has earned Top Performer recognition from PVEL for eleven consecutive years, giving it a considerably stronger institutional and financial footprint.

Trina Solar's product lineup is clearly segmented by application. The Vertex S+ series, built on N-type TOPCon cell technology, targets residential rooftop and small commercial installations, with the latest G3 generation reaching efficiencies up to 22.5% and outputs up to 485 W. The larger-format Vertex N line, with modules exceeding 690 W, is aimed at utility-scale ground-mount and large C&I projects. Trina's 210 mm cell platform underpins most of its high-power offering and has yielded multiple world-record efficiency certifications. Solplanet's module offering is less extensively documented in public sources, which reflects the company's core identity as an inverter and smart energy management provider - panels are positioned as a complement to its ASW inverter lines rather than a standalone product pillar.

For most buyers - whether financing a residential rooftop system or a larger commercial project - Trina Solar is the more defensible default, backed by a decade-plus Tier 1 track record, independent PVEL validation, and the production scale needed to stand behind long-term warranties. Solplanet makes most sense when a buyer is already committed to the AISWEI inverter ecosystem and wants a single-vendor solution; in that context the two brands are complementary rather than directly interchangeable.
