## Summary

Solarspace is a Chinese photovoltaic manufacturer founded in 2011, with production facilities spanning China, Cambodia, and Laos. According to PV InfoLink, the company ranked second globally in solar cell shipments in 2024, and by end of 2023 had reached a cell production capacity of approximately 60 GW alongside module capacity of around 7.2 GW. Solarspace rejoined the Bloomberg New Energy Finance Tier 1 PV module manufacturer list in Q2 2024, confirming its bankability for project finance. Trina Solar, headquartered in Changzhou, China, was founded in 1997 and is now one of the top three solar module manufacturers worldwide, with cumulative shipments exceeding 205 GW and commercial operations spanning more than 100 countries. It retained its BNEF Tier 1 status through Q1 2025 and has earned Top Performer designation from the independent PVEL scorecard for eleven consecutive years. On the basis of institutional track record, financing history, and global scale, Trina Solar holds a meaningfully stronger footprint.

Solarspace's module portfolio covers both PERC and TOPCon technologies - its Lumina II TOPCon panel reaches 22.65% efficiency - and power ratings run from roughly 400 W up to 720 W, making the range suited to residential rooftop systems, commercial and industrial installations, and utility-scale ground mounts alike. Trina Solar has moved its commercial focus firmly toward TOPCon under the Vertex platform: the Vertex N series, including the i-TOPCon Ultra at 760 W and 24.5% conversion efficiency, targets utility and large C&I projects, while the Vertex S+ addresses residential and small commercial buyers. In March 2026, pv-magazine reported Trina Solar unveiling a 485 W TOPCon module at 24.3% efficiency, and the company set a world silicon cell record of 28.0% in April 2026, reflecting an aggressive R&D pace that few peers can match.

For most international buyers - project developers, EPC contractors, or commercial installers - Trina Solar is the stronger default choice. Its combination of BNEF Tier 1 bankability, 11-year PVEL Top Performer streak, deep global distribution, and continuous TOPCon innovation gives lenders and asset owners high confidence. Solarspace is a credible Tier 1 alternative, particularly compelling as a cell supplier and for cost-sensitive utility projects, but it carries less name recognition with European and North American financiers. Where both brands appear in a competitive tender at comparable pricing, the decision can reasonably come down to local availability and after-sales support rather than any fundamental quality gap.
