Solar firms see silicon price fall in coming years
NEW YORK, June 20 (Reuters) - A lack of high-grade silicon
used to make solar power cells is crimping growth in the
renewable energy sector, but prices for the material will ease
in the coming years, industry players said on Wednesday.
After bottlenecks had limited shipments, many companies
expected a supply shortage of the ultrapure polysilicon used in
90 percent of solar cells to ease this year. But strong demand
driven by the rapid growth of photovoltaic manufacturing
capacity has kept the market tight.
The silicon shortage "shrank margins and slowed growth" for
solar companies, John Cavalier, head of renewable energy for
Credit Suisse, told the Renewable Energy Finance Forum,
although the industry is working through those issues.
"We think the constraints are being addressed very
effectively," he said.
Solar cell producers have been signing long-term contracts
to ensure they receive adequate supplies of silicon, yet some
companies are reluctant to lock in prices for the material.
"We prefer, even though we have signed some 10-year
contracts, to sign five-year contracts because it's difficult
to see what the price will actually be," Yuan-Huai Tsuo, chief
executive of Taiwan's Motech Solar , told the
conference.
Tsuo said prices for polysilicon would eventually stabilize
at about $40 per kilogram (2.2 lb), compared to a current price
of about $250 and the 10-year contract price of about $70.
Alf Bjorseth, chairman of Norway's Scatec AS, said his
company had committed to buy only some of its silicon needs.
"We are locking in some long-term supply, (but) the margin
in that business is very high, so we would want to make it
ourselves," he said.
Even so he agreed current price levels were unsustainable.
"The price will come down in the years to come, I'm pretty
sure of that," he said.
Earlier on Wednesday, Norway's Renewable Energy Corp. ASA
said the global supply of silicon would roughly triple
by 2010 to 100,000 to 130,000 metric tonnes.
