Country of origin may be a case here.  I remember years ago that McGuinty, when he was premier of Ontario, welcomed Samsung to the province and talk was that the company would sell solar panels across the American border.  President Obama gave a speech, broadcast in Canada, that countries that located in Canada or Mexico to sell across his border would incur a very big tariff.  At the time, SunEdison was going bankrupt, as well as other US companies and Asian countries were accused of dumping cheap panels across North America.  This type of practice is what the complaints are all about.
