Trina Solar Launches Bifacial PERC Module "DUOMAX Twin"

April 28, 2017 - Trina Solar Limited ("Trina Solar" or the "Company"), a global leader in solar photovoltaic modules, solutions, and services, has launched its high-efficiency bifacial module DUOMAX Twin. The DUOMAX Twin is an innovative solar module integrating the technology of Trina Solar's high-efficiency bifacial PERC cell and the dual-glass DUOMAX module. Following the first sales order for this new product, Trina Solar already supplied 20MW of its DUOMAX twin modules.

Trina Solar is an industry leader in the research and development of PERC cell technology and production, achieving several world records in mono-PERC cell conversion efficiency. The Company's extensive experience in mass-producing DUOMAX modules has been validated by its customers worldwide, with total shipments of over one gigawatt over the past years.

DUOMAX Twin generates power from both the front and back sides of the solar module and performs well even under weak light conditions. The front side receives direct sunlight while the back side receives reflected and scattered light. Compared with traditional single-sided modules, the DUOMAX Twin can deliver as much as 25% additional energy yield.

The DUOMAX Twin enables increased energy density and higher output, while maintaining development costs at a comparable level as for standard modules. By maximizing energy generation, the DUOMAX Twin significantly reduces levelized cost of electricity (LCOE). Since bifacial modules absorb solar radiation from both sides, they allow a variety of tilt and installation options and are ideal for elevated ground, rooftop, desert and snowy area installations or on-water applications. The dual-glass design used in all DUOMAX panels provides extreme durability even in the harshest environments.

Following the first DUOMAX Twin sales order, Trina Solar supplied 20MW of 72-cell modules, with a power output ranging from 340-350W. The project is located in Golmud, China’s Qinghai province, in a sandy area with highly diffuse reflection, which are ideal conditions for DUOMAX twin. Furthermore, the project will also be equipped with trackers, which will enable the DUOMAX twin module's back side to achieve more solar energy through movement via the tracker.
