The Biden administration has big plans for fighting climate change in the United States, including aggressive infrastructure aims. Solar will play a big part in the new agenda, and participants along the value chain are optimistic.
Developers are gearing up. Residential and small commercial installers are confident. In California, mandates for solar on new residential buildings – and soon for solar+storage on new commercial and multi-dwelling residential buildings – offer a template for accelerating the move away from conventional energy. The chart below provides a view of U.S. solar deployment through 2023, but the real potential is much higher. The United States could be a 50 GW-plus annual
market for solar deployment.
In 2020, 91% of U.S. installations were in the grid-connected commercial segment, which includes utility-scale installations. The top-right chart on the next page presents U.S. demand and installations for 2020. Purchases of modules define demand.
The United States has more than 20 GWp of annual demand, 2 GWp of thin-film cell capacity, and an additional 5 GWp of module assembly capacity for imported crystalline-silicon (c-Si) cells. In other words, the country does not have the capacity to serve its market. The U.S. solar market is fragile without sufficient domestic cell manufacturing, and participants have little control over module supply and price. A shock to the supply chain would likely stall market growth, at least temporarily, potentially taking that 50 GWp-plus of potential down to the low teens.
The bottom-left chart on this page presents U.S. shipments of domestically manufactured cells from 2010 through 2020. Again, close to 100% of U.S. domestic shipments are First Solar’s CdTe technology.
In late 2020, accidents in several polysilicon facilities in China took significant amounts of capacity offline. And repairs were delayed due to the pandemic. Add to that the Chinese government’s control of glass supply, despite bifacial module demand acceleration, and prices rose.
Continuing into 2021, shipping costs increased, and a semiconductor shortage affected inverter and tracker manufacturers that were also experiencing rising costs, after years of absorbing margins and passing higher costs to customers. Developers, accustomed to years of price declines, initially tried to wait it out.
Meanwhile, the situation in the Uyghur Autonomous Region of Xinjiang, China, caught the attention of politicians. In anticipation of action from the United States and other countries, China’s central government passed a law on June 10 forbidding Chinese companies from participating in audits of their materials.
Then, on June 24, the U.S. Department of Homeland Security ordered U.S. Customs and Border Protection to issue a withhold release order (WRO) to detain metallurgical silicon produced by Hoshine Silicon Industry Co., Ltd., and its subsidiaries for the use of forced labor in its manufacturing facilities. Hoshine Silicon is the largest metallurgical silicon supplier globally. Its customers are polysilicon producers such as Germany-based Wacker, South Korea-based OCI, Daqo, GCL, Jiangsu Zhongneng, Asia Silicon, Xinjiang GCL, Xinte, and East Hope.
U.S. Customs and Border Protection has begun holding cells and modules at the border, delaying projects, and increasing costs and anxiety for solar developers and installers.
The United States faces a moral and ethical dilemma. On one hand, after years of discussions and delayed action on climate change, governments must act decisively and quickly. On the other hand, forced labor cannot be ignored.
The English philosopher Philippa Foot developed the “trolley problem” in 1967. An out-of-control trolley car is barreling down the tracks toward five trapped people. There is no way to stop the trolley, but if you throw a switch, the trolley will instead barrel down a track where only one person is trapped. So, the choice is five or one.
There is no bargaining with climate change. Unaddressed, it will keep barreling down the tracks. But nor is there any compromising with forced labor or other troubling measures. Nor is there any denying that forced labor may have played a part in the low cell, module, and system prices that the PV industry has enjoyed for many years.
The political timing is right for U.S. solar industry growth to accelerate beyond anyone’s forecast. Behavior has changed, and there is pull from end users. Solar has moved into the political arena, with proponents on the left and the right.
Unfortunately, as indicated, the United States does not have sufficient cell manufacturing to meet its demand, and it will take years to build it. There is sufficient supply unrelated to forced labor in Xinjiang for the United States, but it will be more expensive, and there will be periods of scarcity. Growth will come at a higher cost – but not a higher moral cost. Because, again, there is no compromising with forced labor.
