Another U.S. Solar Company Seeks Exemption From Trump's Tariff

Enphase Energy Inc. doesn’t make solar panels, but it’s still seeking an exemption from tariffs imposed by President Donald Trump.

That’s because the Petaluma, California-based company makes components in the U.S. called microinverters that convert energy produced by photovoltaic panels from direct to alternating current. The problem is Enphase ships these mobile-phone sized devices to manufacturers in Asia to attach to panels before they’re sold in the U.S. That makes them subject to duties, and that’s why Enphase hired a lobbyist this month.
