近幾年全球太陽能產業難以獲利的原因被認為是肇因於中國大陸太陽能面板低價傾銷，造成全球太陽能產業的倒閉潮。中國大陸的超低價格引發了國際間傾銷的疑慮，致使川普政府對太陽能電池、模組徵收最高關稅，而有業者認為川普政策有益於導正市場步上正途。

The reason why the global solar industry is difficult to make profit in recent years is believed to be due to the low-cost dumping of solar panel makers in mainland China, causing the global solar industry to collapse. The ultra-low prices in mainland China have caused the Trump government to impose the highest tariffs on solar cells and modules. Some industry players believe that Trump ´s policies are helpful to guide the market on the right path.
