SunPower Corp <SPWR.O> on Wednesday said it would buy U.S. solar panel maker SolarWorld Americas, expanding its domestic manufacturing as it seeks to stem the impact of Trump administration tariffs on panel imports. Terms of the deal were not disclosed. The news sent SunPower's shares up 12 percent on the Nasdaq to their highest level since before President Donald Trump imposed 30 percent tariffs on imported solar panels in January. SunPower is based in San Jose, California but most of its manufacturing is in the Philippines and Mexico. The company had lobbied heavily against the solar trade case brought last year by U.S. manufacturers, including SolarWorld, which said they could not compete with a flood of cheap imports. The deal is a win for the Trump administration's efforts to revive U.S. solar manufacturing through the tariffs. SunPower will manufacture its cheaper "P-series" panels, which more directly compete with Chinese products, at the SolarWorld factory in Hillsboro, Oregon, it said. SourceStochastics are overbought, the price will go down and probably will close the gap. $SPWR, SunPower Corporation / D
