You got that all wrong: FSLR facing major difficulties next (see latest news!), along with some other western solars.
Uncle China has a bottomless wallet and will not allow tier I solars to fail, seeing as solar is one of the almighty CCP's top priorities in their latest 5-year plan. Said plan includes annually increasing solar investments in mainland China and implies strong support for the main players, among other things.
STP's business in the US will be least impacted by present and any future tariffs as they have substantial local production and were deemed the lowest tariff of 2.9% vs. 3.59-4.73% for all other Chinese producers.
In the long run the whole industry has a brilliant future and the Chinese will benefit, alas, from a strategy spanning decades vs. the quartile or electoral myopia of western democracies.
