Trinasolar (天合光能)

Company Overview

Trinasolar, or Trina Solar Co., Ltd., is one of the large Chinese solar manufacturers and a familiar name to anyone sourcing PV hardware at volume. The company states it was founded in 1997 and is listed on Shanghai's STAR Market under stock code 688599, with its global headquarters in Changzhou, Jiangsu, and an international headquarters in Shanghai. Manufacturing and operations extend across several Chinese sites including Changzhou, Yancheng, Suqian, Yiwu and Xining, and the company reports a workforce of nearly 25,000 people worldwide.

For a buyer, the relevant point is scale plus vertical integration. Trinasolar is not a trading company reselling someone else's panels. It develops its own cell technology, makes modules, builds trackers and sells storage systems, and it appears on Tier 1 classifications for both PV modules and energy storage.

Main Products

PV modules — the Vertex N series (n-type i-TOPCon technology) and the Vertex S+ series aimed at rooftop and distributed generation. The company has publicly referenced Vertex N modules in the 700W class for utility projects.
Energy storage — the Elementa series of battery storage systems for utility-scale, commercial and industrial, and residential applications, using the company's own cells.
Trackers — TrinaTracker Vanguard single-axis tracking systems with smart control software.
System and digital energy services — distributed generation, centralized plants, microgrids and O&M services.

Certifications and Quality Signals

Trinasolar states it has set world records for PV cell efficiency and module output, including a 33.9% efficiency result for a large-area perovskite/silicon tandem cell and 28% for its TOPCon-compatible hybrid back-contact cell. It has been named a Tier 1 company for both PV modules and energy storage systems on the S&P Global Tier 1 Cleantech list. Buyers should still verify the specific model certificate for their destination market (UL/IEC for the US, CE/EN for Europe, and separate listings such as the Clean Energy Council in Australia) directly with the issuing body — certificates are issued per model and per factory, not per brand.
