Trina Solar has said that it has successfully reached 100 percent
commercial production of 200 micron thickness wafers, down from the
previously used 220 micron thickness as the company attempts to improve
silicon usage and lower manufacturing costs.

“During the quarter we commenced in-house test production of both
multicrystalline ingots and wafers, and we fully reduced our
monocrystalline wafer production thickness from 220 to 200 microns
thickness in line with our stated goals to expand capacity while
reducing costs as a vertically integrated solar PV manufacturer,” said
Mr. Jifan Gao, Trina Solar’s Chairman and CEO.

Trina Solar is
also planning a new polysilicon production facility as part of its
vertically integrated business model. The first phase of the
polysilicon production facility will have a production capacity of
3,500 metric tons and the project will eventually scale to a 10,000
metric ton production capacity.

However, the company reiterated
that even with its own polysilicon production, it would still need to
secure feedstock materials via long-term contracts. The company
recently announced that Nitol Group would supply the equivalent of
200MW of virgin
polysilicon to be delivered over five years starting
in 2009, as well as a six-year polysilicon supply agreement with
Sichuan Yongxiang Polysilicon Co., Ltd.

The company said it was
still on track to meet its fully integrated capacity goals of 150MW and
350MW for 2007 and 2008 respectively.

Trina Solar has also
started commercial scale production of its new cell lines 3 and 4,
which are currently producing at 100 percent capacity using 156mm cells
with cell efficiency levels of 16.4 percent, according to the company.

Trina
Solar stated that it had signed sales contracts representing
approximately 100 percent of its expected module production for the
first half of 2008 and 50 percent already allocated in the second half
of next year.

The Renewable Energy Trading Summit is the only event in Europe dedicated to renewable energy trading and will bring together renewable power asset owners, investors, exchanges, intermediaries and large energy buyers to discover the future of power sales. This unique event is designed specifically for the most senior players and will provide an excellent forum for business deals, networking and learning. The energy transition is gathering pace with renewable energy attracting increasing sums of capital each year. Solar and wind deployment is increasing annually and governments are ever-more reliant on the renewables sector to stimulate moribund economies. Retirement of fossil fuel assets continues in the background. However, without subsidies and uncertainty around PPAs, renewable asset owners are heading into the wholesale markets to trade power but are they ready for the volatility in revenue this will entail?

The proliferation of solar PV and other renewables is a cornerstone of the emerging new power system and, as a result, the solar industry has entered its fastest-growth period. This has become typified by surging demand for high-power PV modules that both produce more power and are more efficient than their predecessors. Providing a significant boost to power outputs, large-format modules have become a popular choice for customers the world over. Outdoor testing of modules is now providing empirical evidence of the benefits large-format modules produce, providing a crucial benchmark and invaluable data for customers to evaluate their module selection and procurement processes. In this PV Tech webinar, experts from TÜV Rheinland, CPVT and Trina Solar will discuss how to ensure science based and precision testing under field conditions, how empirical data is collected and analysed during TÜV Rheinland and CPVT’s outdoor testing, the empirical data behind a 670W module’s ultra-high power, and more.
