Solar energy equipment imported from China will now have duties of as much as 4.73%, according to the U.S Commerce Department. The tariff is modest compared to most trade cases, but still an important step in giving American companies a fighting chance in the markets.

U.S. suppliers of solar equipment have long complained that Chinese manufacturers benefit from high government subsidies that allow them to sell panels at a discount. Attempting to match prices has meant razor-thin price margins for other producers. "The prices of solar modules, or panels, fell 50% last year, largely as a result of the cheap Chinese imports," explained Timothy Brightbill, an attorney for SolarWorld, before the Commerce Department's decision was made.

As per the U.S. decision, Suntech Power Holdings was told to pay a 2.90% tariff, while Trina Solar (NYSE: TSL) will pay 4.73%. All other Chinese solar-equipment firms were told to pay 3.59% (via Bloomberg).

So, what effect will this tariff have on solar stocks?

The case had been high profile, and many expected heavier tariffs than what was given. The Wall Street Journal reports the lower-than-expected duties sparked a stock rally among large Chinese solar-panel makers. Meanwhile, American depositary shares of Suntech Power Holdings jumped 14.06%, while Trina Solar Ltd. rose by 7.85%.

Indeed, "Both sides claimed victory in the Commerce Department's decision Tuesday."
