Panel Reduces Installation Cost and Maximizes Inventory Flexibility

San Jose, California, February XX, 2012 -- Trina Solar Limited (NYSE: TSL) ("Trina Solar" or the "Company"), a global leader in photovoltaic modules, solutions and services, today announced that a new line of 72-cell modules has been certified by Underwriters Laboratories (UL) and TÜV Rheinland, according to UL 1703 and IEC 61215/61730 respectively, to have a rated system voltage of 1000V. The dual rated modules provide the high performance expected from a Trina Solar module while delivering a lower total cost of installation and greater inventory and project flexibility.

The new dual rated modules continue the Company's commitment to provide better solutions for Trina Solar partners. These new modules incorporate the most recent advances in polysilicon-based solar technology innovations to enable installers and developers to now use them for either utility ground mount or commercial rooftop installations. High transparency, 4.0mm thick tempered glass provides enhanced module durability and MC4PLUS photovoltaic connectors increase system reliability. Additionally, the dual rated modules enable longer PV strings, resulting in fewer combiner boxes, fewer wiring needs and lower installation labor costs. The new modules are backed by Trina Solar's 25-year linear power warranty.

"Trina Solar continues to meet the evolving needs of our partners," said Mark Mendenhall, President of Trina Solar Americas. "Our new, dual rated modules provide the flexibility that our partners have asked for while delivering the high performance they've come to expect. Ultimately, we have taken another step to give our partners better ways to meet their installation needs while reducing the total cost of installation."

The UL and IEC (International Electrotechnical Commission) dual rated modules are California Energy Commission (CEC) listed. Unlike standard modules, the dual rated modules can be used to satisfy installation requirements for either commercial rooftop or utility scale installations in North America or Europe.

The new dual rated modules continue the Company's track record of product leadership, industry firsts and strategic investments in the long-term growth of its partners and the solar industry overall. Earlier this year, the Company unveiled new, cutting-edge products including Trinasmart and Trinamount that speed the installation process, as well as Design Services that deliver preliminary system layouts. The combination of diverse product offerings and services highlights Trina Solar's expanding commitment to providing a full range of solar solutions to its partners throughout the value chain.

Trina Solar has received recognition by two organizations for its sustainable practices and field performance. The Silicon Valley Toxics Coalition, in its annual global review of sustainable manufacturing practices, ranked the Company first among solar panel manufacturers throughout the world. Additionally, Trina Solar's panels rank near the top of all polysilicon-based modules the California Energy Commission's PTC/STC ratio that estimates real-world panel performance.
