While the impact of the tariffs is not expected to hit as hard in 2018, as many buyers bought solar equipment before the tariffs went into effect, GTM predicts U.S. growth in solar installations to plateau this year at 10.6 gigawatts. Additionally, GTM says that growth in utility-scale solar will idle between 2020 和 2022 because of the tariffs, as projects may become delayed or abandoned, CNBC 报告。在北卡罗莱纳州和佛罗里达州等受监管的市场中，“由于州电力主管部门保证了投资回报率”，预计项目将继续进行。
On the bright side, 2017 marked the second straight year of double-digit gigawatt growth in the solar industry. The sector added 10.6 gigawatts of photovoltaic capacity, the most common type of solar power technology. "The solar industry delivered impressively last year despite a trade case 和 market adjustments," SEIA President 和 CEO Abigail Ross Hopper said in a press release. "Especially encouraging is the increasing geographic diversity in states deploying solar, from the Southeast to the Midwest, that led to a double digit increase in total capacity."
