Leveling Up Solar Manufacturing: What You Need To Know About Treasury’s New Final Rules Under Sections 45X and 48D

The Inflation Reduction Act (IRA) and the CHIPS Act have unleashed billions of dollars of new investments in domestic manufacturing, including a significant down payment on the solar manufacturing sector of the future. The IRA’s Advanced Manufacturing Production Tax Credit (Section 45X) was designed to ensure that the hundreds of gigawatts of clean energy capacity projected to come online in the next decade are built with U.S.-made products, benefitting the American workers and companies making those products here at home. Meanwhile, the CHIPS Act seeks to bolster American competitiveness in semiconductor manufacturing (Section 48D), which now includes the polysilicon ingots and wafers used to make solar modules for generating electricity.

On October 22, the IRS released final rules under Section 48D that make polysilicon ingot and wafer manufacturing facilities eligible for a 25% investment tax credit through 2026; and on October 24, final rules under Section 45X clarified and expanded a number of key provisions for clean energy, including those related to module, inverter, and energy storage technologies, as well as critical mineral extraction. Both final rules contain a number of significant changes from proposed rules issued in 2023 that will be essential to continuing our rapid domestic manufacturing growth.

Join us at 12:00pm ET to hear from SEIA leaders on tax and manufacturing policy, including Q&A, where you will learn about:

  • How Section 48D applies to the solar industry and how it differs from credits under the Inflation Reduction Act
  • Major changes to Section 45X rules on inverters, module-level power electronics, energy storage technologies and more
  • Next steps in the policymaking process
  • SEIA resources on solar manufacturing

Panelists:

  • Ben Norris, Vice President of Regulatory Affairs, SEIA
  • Jeremy Woodrum, Senior Director of Congressional Affairs, SEIA
  • Jade Jones, Director of Supply Chain Analysis, SEIA
