The 500W+ V series modules, with a module conversion efficiency reaching 21%, boast a power output over 500W. Incorporating 210mm cells, the 500W+ V series modules come in two versions – the Duomax V bifacial double-glass modules and Tallmax V back sheet modules – and can be seamlessly connected to existing mainstream photovoltaic system designs, including tracking solutions.

Several industry firsts

Based on Trina Solar's multi-busbar technology, the modules incorporate an innovative design that integrates advanced three-piece, non-destructive cutting and high-density packaging technologies, eliminating the potential risks associated with ultra-high power modules: voltage, current and thermal overload as well as micro cracks.

To address the new challenges, the company and its partners, at the initiative of Trina Solar, jointly developed several industry firsts according to the company: a high-speed non-destructive cutting technology, uniform welding for multi-busbar solar modules made of 210mm cells, a new methodology for automated layout of solar panels as well as laminated welding equipment capable of handling mass production. These firsts, when integrated into the manufacturing process, help to achieve steady production.

Solar 5.0 era - ultra-high power modules

Trina Solar vice general manager and executive vice president Yin Rongfang said, "The 500W+ V series modules are the result of many technological improvements to the manufacturing process undertaken over the last 20+ years combined with our accumulated experience in many aspects of the end-to-end process, including product integration and downstream systems. The successful pilot line for the mass production of the 500W+ V series modules has laid a solid foundation for the capacity expansion to 5.5 GW this year, leading the global photovoltaic industry into the solar 5.0 era and a win-win market for ultra-high power modules."
