Trina Solar Reaches Efficiency and Output Milestone

Trina Solar Limited, a leading integrated manufacturer of solar photovoltaic products from the production of ingots, wafers and cells to the assembly of PV modules, founded in 1997, announced today the following updates relating to its previously stated capacity, operational, and technology roadmap targets that were achieved in the quarter ended December 31, 2007:

  • 150MW integrated capacity achieved for ingot, wafer, cell and module production
  • Successful ramp up of new cell production lines No. 3-6
  • Increased in-house cell processing to over 75% for the Q4 2007 production
  • Realized in-house cell efficiency rates of up to 17.0% (monocrystalline) and 15.6% (multicrystalline)
  • Commenced commercial production of 220-watt multicrystalline-based modules

"We are extremely pleased to have reached several operational goals in the fourth quarter of 2007," said Trina Solar's Chairman and CEO, Jifan Gao. "We achieved all-time highs in both in-house cell efficiency and output rates for our six cell manufacturing lines, which will have notable impact on our margin expansion. Going forward, we will continue to focus on decreasing module manufacturing costs through additional gains in cell efficiencies, reduced polysilicon usage, and production scale advantages achieved by the execution of our technology roadmap. These advancements will continue to be driven by technology transfer, operational synergies and quality assurance advantages provided through our vertical manufacturing platform."

2008 Sales and Technology Roadmap Update

As of this date, the Company has pre-sold 100% and 75% of its first and second half 2008 targeted module production, respectively, representing approximately 85% of its targeted module production of 200-210 MW for 2008.

The Company plans to initiate production tests of 180 micron wafers and cells in the first half of the year, with goals to reduce thickness to 140 and 160 microns by 2010 for its mono- and multicrystalline-based cells, respectively. Cell efficiency rates are expected to reach approximately 19% and 18% by 2010 for mono- and multicrystalline-based cells, respectively, yielding module power to approximately 240-250 watts. In December 2007, the Company's existing and newly launched multicrystalline cell lines achieved average cell efficiency rates of 16.6% and 15.3%, respectively.

2008 and 2009 Silicon Feedstock

The Company has now secured over 80% of its estimated silicon feedstock requirements for 2008, an equivalent of approximately 165MW based on a module production target of 200-210MW of module output. Through its established supply channels and proprietary in-house processes, the Company continues to source up to 80% of its feedstock requirements from reclaimed silicon sources, resulting in cost savings of 30-50% over the spot market cost for virgin polysilicon. For its 2009 planned module production of 400MW, the Company has secured approximately 60% of its total feedstock requirements, or an equivalent of approximately 240MW. The Company's long-term polysilicon contracts currently account for over 40% of its total 2009 silicon requirements.
