The U.S. Trade Representative on Sept. 19 granted exclusions from import duties for certain solar products. These include 45-W off-grid solar panels, 120-W flexible and semi-flexible off-grid panels designed for motor vehicles and boats, 90-W frameless panels in colors other than black or blue, back contact solar cells, and modules using U.S.-made solar cells. Solar developer SunPower Corporation announced that its “interdigitated back contact” or IBC solar cells and modules benefit from the exclusion, supporting the company’s planned acquisition of the SolarWorld Americas facility in Oregon. The Trump administration slapped tariffs on panels in January after bankrupt solar manufacturers Suniva and SolarWorld asked for relief, citing a flood of cheap, foreign imports. The tariffs will phase down from 30 percent in increments of 5 percentage points over three years. SunPower Corporation is a subsidiary of Total Solar International SAS. SolarWorld Americas Inc. is a subsidiary of SolarWorld Aktiengesellschaft.
