Prospect of Trump tariff casts pall over U.S. solar industry

LOS ANGELES, July 25 (Reuters) - U.S. solar companies are snapping up cheap imported solar panels ahead of a trade decision by the Trump administration that could drive up costs and cloud the fortunes of one of the economy's brightest stars.

Domestic consumers and businesses have been embracing solar energy at a furious pace - thanks to a big assist from China. Low-cost photovoltaic cells and panels made in China and other Asian countries have helped drive down costs by around 70% since 2010, enabling more Americans to go solar.

Installations in the United States last year hit a record. Jobs are mushrooming too. The domestic industry now employs more than 260,000 people, according to The Solar Foundation, most of them construction workers hammering panels on rooftops and erecting utility-scale solar plants in the nation's blistering deserts.

But signs of a chill are already visible as the industry waits to see how President Donald Trump responds to a recent trade complaint lodged by a Georgia manufacturer named Suniva. The company has asked the administration effectively to double the price of imported solar panels so that U.S. factories can compete. About 95% of cells and panels sold in the U.S. last year were made abroad, with most coming from China, Malaysia and the Philippines, according to SPV Market Research.

Trump has wide latitude to levy tariffs to protect domestic firms. His actions could determine whether sun-powered electricity can compete with fossil fuels to light the nation's homes and businesses.

The White House would not comment on the solar trade case. But the administration has vowed to protect steelmakers and other U.S. manufacturers by penalizing "unfair" imports.

That has the solar industry bracing for the worst. Panic buying has sent spot prices for solar panels up as much as 20 percent in recent weeks as installers rush to lock up supplies ahead of potential tariffs.

Skittish U.S. energy customers are putting some solar projects on hold. Manufacturers are eyeing other markets to develop. And some investors are running for cover. Funding for large U.S. solar deals fell to $1.4 billion in the second quarter, down from $3.2 billion in the first quarter and $1.7 billion a year earlier, primarily due to concerns about the trade case, according to research firm Mercom Capital Group.

Developers of solar farms that provide utilities and big companies with energy are particularly vulnerable; panels account for as much as half of the cost of their projects.

A steep rise in panel prices "could be huge and disastrous for large-scale solar," said Tom Werner, chief executive of San Jose-based SunPower Corp, a top U.S. solar company that is majority owned by France's Total. "Developers are alarmed and planning."
