IRA Updates for Solar ITC

The Inflation Reduction Act marks a significant step towards encouraging the adoption of solar energy systems in the United States. This legislation brings substantial changes to existing tax credits, notably expanding opportunities for both residential homeowners and manufacturers.

Extension of the Solar Investment Tax Credit (ITC)

The Inflation Reduction Act has extended the Solar Investment Tax Credit (ITC), providing significant benefits to residential homeowners. Those installing eligible solar systems from January 1, 2022, through the end of 2032, can now claim a tax credit of 30% of the installation cost against their federal income taxes. This credit makes solar installations more accessible and affordable for homeowners, fostering the growth of renewable energy at a grassroots level.

Carryover of Tax Credits

If homeowners owe less in federal taxes than the credit amount in the year of installation, they can carry over the unused credit until the expiration of the ITC on January 1, 2032. This provision ensures that homeowners fully benefit from the tax credit, regardless of their liabilities.

Post-2032 Phase-Out

After 2032, the residential ITC will start phasing down – to 26% in 2033, 22% in 2034, and will be discontinued after 2035. This gradual reduction underscores the need for homeowners to act promptly to maximize their tax benefits.

Introduction of the Advanced Manufacturing Production Credit (Section 45X)

The Inflation Reduction Act introduces a new Production Tax Credit (PTC) – the Advanced Manufacturing Production Credit (Section 45X) – targeting the domestic production and sale of solar, wind, and battery components. This initiative is a strategic move to boost the U.S. solar manufacturing industry, enabling it to compete more effectively on the global stage.

Eligible Solar Components

This credit covers a range of solar components, including photovoltaic cells, wafers, and modules, with the credit amount determined per watt or per production quantity. This approach incentivizes increased production volumes and supports the scaling of the solar manufacturing sector in the U.S.

Restrictions and Eligibility

Manufacturers cannot access the Advanced Manufacturing PTC for components produced at facilities that previously received benefits from the Section 48C credit. Production must start after December 3, 2022, with the credit beginning to phase out from 2030.

Direct Pay Options for Tax-Exempt Organizations

The act also introduces a “direct pay” option for tax-exempt entities. This allows them to receive payments instead of tax credits for renewable energy production. This provision is particularly beneficial for organizations not subject to federal income taxes, such as those with a 501(c) designation. It allows these entities to take a more active role in renewable energy production, although the benefit may diminish if tax-exempt debt largely finances the project.


The Inflation Reduction Act significantly broadens the scope for solar energy adoption in the U.S. By extending the Solar Investment Tax Credit, introducing the Advanced Manufacturing Production Credit, and providing direct pay options for tax-exempt organizations, it encourages increased solar energy production and usage. These changes are expected to accelerate the growth of the solar industry, contributing to energy independence and environmental sustainability.
