According to a new analysis published by the Solar Energy Industries Association (SEIA), since the Inflation Reduction Act (IRA) passed one year ago, US solar and storage companies have announced over 100 billion dollars in private sector investments, helping bolster the American economy.

Solar and storage manufacturing is now surging in the United States, as 51 solar manufacturing facilities have been announced or expanded in the last year, SEIA says.

"The unprecedented surge in demand for American-made clean energy is a clear sign that the clean energy incentives enacted last year by Congress are working," said SEIA president and CEO Abigail Ross Hopper. "This law is a shining example of how good federal policy can help spur innovation and private investment in communities that need it most. We are unleashing abundant clean energy that is creating jobs and capable of delivering affordable, reliable power to every home and business in this country."

These new and expanded solar factories will invest nearly $20 billion into American communities and will amount to 155 gigawatts (GW) of new production capacity across the solar supply chain. These announcements include 85 GW of solar module capacity, 43 GW of solar cells, 20 GW of silicon ingots and wafers and 7 GW of inverter capacity.

By 2026, SEIA says that the US will have over 17 times its current manufacturing capacity across modules, cells, wafers, ingots, and inverters when these announced factories are in operation, which is enough to supply a majority of solar projects expected to be built in the US.

The good times for employment

According to the report, over the next decade, the US solar and storage industry will create 137,000 more jobs than it otherwise would have before the IRA was passed, with the entire industry workforce projected to grow to nearly 500,000 jobs by 2033.

Solar manufacturing facilities announced in the last year will employ more than 20,000 Americans. The nation’s solar manufacturing workforce is set to triple in size to over 100,000 jobs in the next decade, SEIA says.

In addition, 65 GWh of energy storage manufacturing capacity has been announced across 14 new or expanded facilities. Since the IRA was passed, over 3 GW of new large-scale energy storage projects have been deployed, and an estimated 100,000 customers have installed a residential solar system paired with battery storage.

By 2033, US solar capacity will reach 668 GW, enough to power every home east of the Mississippi River and offset 459 million metric tons of CO2 annually. These reduced emissions from solar represent roughly one-third of all power sector emissions in 2021. Finally, SEIA explains that the solar industry will generate 565 billion dollars in private sector investments over the next decade.
