Trina Solar's Vertex S+ Clear Black tops PV Magazine Test for reliability and energy yield

Trina Solar's Vertex S+ clear black module clinched top spot in an indoor performance test with an impressive average score of 92, in a PV Magazine test published last month. It also emerged victorious in the field test for energy yield conducted in January. These findings serve as compelling evidence of the module's capacity to maintain exceptional stability performance in challenging environments, underscoring its unparalleled reliability and stability.

The PV Magazine test, organized by PV Magazine Group, comprehensively assessed the performance and energy output of PV modules. The evaluation encompassed indoor performance evaluations and field test for energy yield.

To ensure the integrity and impartiality of the results, CEA, a reputable consulting firm in the industry, was enlisted as a third-party technical expert to oversee the testing process.

During the indoor test environment session, the Vertex S+ clear black module from Trina Solar stood out with an outstanding average score of 92 points. Comparative analysis against modules used technologies such as HJT, p-type IBC, n-type IBC. The Vertex S+ clear black module, distinguished by its aesthetic appeal, outperformed its counterparts in key areas such as appearance, EL, low-light performance, temperature coefficient and PID.

Field tests are the most reliable way to assess a module's power generation capabilities. In January the Vertex S+ clear black module demonstrated exceptional performance in the TOPCon/HJT group's field test, securing top position on the monthly list with an impressive energy yield of 43.24Wh/Wp.

The Vertex S+ clear black module combines 210mm rectangular silicon wafer (210R) cell technology with n-type i-TOPCon advanced technology, resulting in enhanced 22.3% efficiency and impressive power output of up to 445W+. The module's bifacial dual-glass design enhances energy yield, and its lightweight structure ensures exceptional reliability and safety. Additionally, its sleek black aesthetic is tailored for upscale household roofs, carports and public spaces.

Cao Yunduan, head of branding and global marketing at Trina Solar, said: “Vertex S+ series modules represent a pinnacle of innovation and performance in the solar industry. The impressive performance of the Vertex S+ module in the recent test session reaffirms our dedication to delivering superior products that meet the evolving needs of our customers.”
