Solar earnings season begins next week, and Chinese solar companies have a lot to gain and lose. Worldwide installations are expected to grow to over 50 GW, and the U.S. alone is forecast to 6.6 GW, according to Greentech Media. 

But tariffs were recently put on Chinese solar imports, and companies who once sold into the growing U.S. market could be left out in the cold. Three of the biggest manufacturers in the world could be in for a rough quarter because of those tariffs. Trina Solar (NYSE:TSL) sold 32% of its panels into the U.S. in the first quarter, Yingli Green Energy (NYSE:YGE) sold 24% of its product, and Canadian Solar (NASDAQ:CSIQ) had 41% of its revenue come from the Americas and has 151 MW in project backlog in the region. 

In the video below, solar specialist Travis Hoium covers why it could be a rough quarter for these solar manufacturers.
