Suniva Dispute Could Halt Two-Thirds of US Solar Installations Through 2022

Suniva's new trade dispute would strike a devastating blow to the U.S. solar market, erasing two-thirds of installations expected to come online over the next five years.

If Suniva's petition is successful, shockwaves will be felt across all segments of U.S. solar. Utility-scale solar is most at risk, with more than 20 gigawatts already at risk of cancellation if module prices fall back to 2012 levels.

GTM Research crunched the numbers based on Suniva's requested penalties for imported solar equipment ($0.40/watt tariff for cells and a floor price of $0.78/watt on modules) and found that they would cause unprecedented demand destruction.

If Suniva's proposal is approved by the U.S. International Trade Commission and President Trump, there will be a new minimum price on imported crystalline silicon solar modules, and a new tariff on imported cells. Put together, the U.S. could miss out on more than 47 gigawatts of solar installations. That's more than what the U.S. solar market has brought online to date.    

In our latest report we found that between 2018 and 2022, total U.S. solar installations would fall from 72.5 gigawatts cumulatively to just 36.4 gigawatts under a $0.78 per watt minimum module price scenario. Even more dramatic, with a $1.18 per watt minimum price, representing a $0.40 per watt cell tariff on top of a $0.78 per watt minimum module price, cumulative installations would plummet to 25 gigawatts.

The utility-scale PV segment is expected to see the largest downward revisions to its base case forecast.

A majority of utility PV procurement now hinges on solar being cost competitive with natural gas alternatives, with nearly three-fourths of the utility PV pipeline procured outside renewable portfolio standards. Under both tariff scenarios, most of that pipeline is at risk of cancellation unless PPA prices are renegotiated. That could wipe out a number of state markets altogether under either tariff scenario.

Residential PV is the least sensitive segment to the introduction of tariffs. On one hand, the number of residential state markets at grid parity would fall from 43 to 35 under the minimum module price only scenario (43 to 26 with the cell tariff added to the minimum module price). However, on the other hand, the top six state markets, which drive a majority of the base case outlook, would continue to offer more than 10 percent annual net savings.

Over the next several years, residential PV can still rely on California and the other major northeast state markets to remain above the tipping point under both tariff scenarios.

Meanwhile, the non-residential PV segment is likely to be more sensitive to new tariffs than residential PV, given that 40 to 50 percent of the base case outlook depends on large C&I customers with challenging rate structures, plus the nascent community solar segment riddled with project development and financing risks.

Uncertainty looms over the U.S. solar market and within the trade dispute itself. Our latest report outlines how the trade case might, or might not come to fruition, and if it does, how it will impact each market segment through 2022.
