Trina Solar Vertex S+ 505W n-type dual-glass modules enter mass production

Trina Solar Co., Ltd ("Trina Solar" or the "company"), a global leader in smart PV technology and energy storage solutions, has announced that the first Vertex S+ 505W (NEG18R.28) rolled off the production line at its factory in Changzhou, Jiangsu province, on January 25, marking the beginning of mass production. It is part of the Vertex S+ series specifically designed for commercial and industrial rooftops.

Guided by higher power and lower BOS and LCOE, the Vertex S+ 505W is tailored to meet customers’ key requirement of a shorter payback time. Combining n-type i-TOPCon technology with 210mm rectangular silicon wafer (210R) cell technology, this dual-glass module will yield up to 505W power and deliver efficiency as high as 22.7%. This results in a a longer lifespan, less light-induced degradation and higher conversion efficiency than with p-type modules.

With dimensions of 1961mm by 1134mm and a slim width of 30mm, the 1.6 + 1.6mm dual-glass module weighs only 23.5kg. This makes installation straightforward and ensures that panels are robust enough for larger-scale commercial installation. The module offers a variety of flexible installation solutions for system deployment. Thanks to its short circuit current of 15.86A, it is highly compatible with most mainstream inverters, optimisers and mounting systems on the market.

The 1.6+1.6mm dual-glass design provides increased scratch, crack and impact resistance and ensures the panel’s resistance to salt spray, acids, alkalis, high temperature and humidity, helping the panel to pass the 35mm hail test and meet the IEC fire rating (Class A+C). The reliability of PV systems built with Vertex S+ 505W will guarantee lifetime power output within the ultra-long 30-year performance warranty and 25-year product warranty. These extended warranties underscore Trina Solar’s confidence in its dual-glass technology and in the long-term performance of n-type i-TOPCon cells.

Adding to the dual-glass panels’ higher power generation and improved reliability, Vertex S+ 505W modules’ ultra-low degradation rates, including extremely low 1% first-year and 0.4% annual degradation, give greater assurance to commercial and industrial property owners and managers seeking to improve their site’s long term energy efficiency.

Trina Solar's Vertex S+ series modules have been recognised in the non-utility market by industry partners and customers. The mass production of Vertex S+ 505W will guarantee subsequent full delivery to Europe, Australia, the Asia-Pacific and other regions.

Trina Solar is committed to enhancing the competitiveness of its products, creating greater value for customers, and contributing to the global transition to renewable energy.
