Is China Beating the US in Solar?

President Obama wants to make the United States “the world’s leading exporter of renewable energy,” but in his seven months in office, it is China that has stepped on the gas in an effort to become the dominant player in green energy — especially in solar power, and even in the United States.

Chinese companies have already played a leading role in pushing down the price of solar panels by almost half over the last year. Shi Zhengrong, the chief executive and founder of China’s biggest solar panel manufacturer, Suntech Power Holdings, said in an interview here that Suntech, to build market share, is selling solar panels on the American market for less than the cost of the materials, assembly and shipping.

Backed by lavish government support, the Chinese are preparing to build plants to assemble their products in the United States to bypass protectionist legislation. As Japanese automakers did decades ago, Chinese solar companies are encouraging their United States executives to join industry trade groups to tamp down anti-Chinese sentiment before it takes root.

The Obama administration is determined to help the American industry. The energy and Treasury departments announced this month that they would give $2.3 billion in tax credits to clean energy equipment manufacturers. But even in the solar industry, many worry that Western companies may have fragile prospects when competing with Chinese companies that have cheap loans, electricity and labor, paying recent college graduates in engineering $7,000 a year.

“I don’t see Europe or the United States becoming major producers of solar products — they’ll be consumers,” said Thomas M. Zarrella, the chief executive of GT Solar International, a company in Merrimack, N.H., that sells specialized factory equipment to solar panel makers around the world.

Since March, Chinese governments at the national, provincial and even local level have been competing with one another to offer solar companies ever more generous subsidies, including free land, and cash for research and development. State-owned banks are flooding the industry with loans at considerably lower interest rates than available in Europe or the United States.

Suntech, based here in Wuxi, is on track this year to pass Q-Cells of Germany, to become the world’s second-largest supplier of photovoltaic cells, which would put it behind only First Solar in Tempe, Ariz.

Hot on Suntech’s heels is a growing list of Chinese corporations backed by entrepreneurs, local governments and even the Chinese military, all seeking to capitalize on an industry deemed crucial by China’s top leadership.

Dr. Shi pointed out that other governments, including in the United States, also assist clean energy industries, including with factory construction incentives.

China’s commitment to solar energy is unlikely to make a
