The President placed a 30 percent tariff on solar module imports to the US in January 2018 (see Energy on WI January Newsletter). The tariff will last four years, annually decreasing by 5 percent. Reports now show that renewable energy companies have cancelled or frozen $2.5 billion worth of large solar installation projects, impacting thousands of jobs. Solar project costs are impacted by tariffs on steel as well, used for racking. The Heartland, that had the strongest growth in installations last year, will be hurt by the tariffs in the short-run. Solar installation projects are now more expensive for many companies, and solar developers are choosing only to proceed with projects in other regions of the US, where renewable energy incentives allow profitability.
