The phase-out of the federal solar tax credit, also known as the Investment Tax Credit (ITC), will have significant implications for the long-term adoption of solar energy in the United States.
Current Status and Timeline of the Solar Tax Credit
- As of early 2025, the solar tax credit remains at 30% of the cost of solar system installations for both homeowners and businesses. This rate is set to continue through 2033.
- Starting in 2033, the credit will reduce to 26% for property placed in service that year and then further decline in subsequent years.
Effects of the Phase-Out on Solar Adoption
Positive Impact While the Credit is Active
- The 30% tax credit significantly lowers the upfront investment barrier for installing solar panels, making solar energy more accessible and affordable. For example, typical solar system buyers save thousands of dollars, with EnergySage reporting average savings around $8,800 per installation.
- This incentive has driven widespread adoption, fostering renewable energy growth, accelerating the shift to clean energy, and supporting economic growth in the solar installer market through job creation and technology development.
Challenges and Limitations
- The tax credit primarily benefits those who owe federal taxes and can utilize the credit, making it less accessible to lower-income households or renters, which limits broad equity in solar adoption.
- Because the credit phases out over time, uncertainty about future incentives can complicate long-term planning for homeowners and solar companies, potentially slowing investment during transition periods.
- The requirement that homeowners own their systems (and not lease or use power purchase agreements) to claim the credit further limits the credit’s reach.
Long-Term Outlook After Phase-Out
- As the credit phases down to 26% and eventually phases out past 2033, the upfront cost reduction of solar installations will diminish, potentially slowing the rate of new solar adoption unless other incentives or cost reductions compensate.
- However, continued declines in solar technology costs and increased awareness of solar’s benefits may sustain adoption to some extent despite the reduction in tax incentives.
- States and local governments may increase complementary incentives or policies to offset the federal tax credit phase-out and continue promoting solar adoption.
Summary
The phase-out of the solar tax credit will likely slow the rapid growth seen during its highest levels due to reduced financial incentives. Initial strong adoption driven by the 30% credit will taper as the credit declines after 2033. However, the solar industry may remain viable because of ongoing technology cost reductions, other policy supports, and growing demand for clean energy. The transition will require careful policy and market adjustments to maintain the pace of solar energy adoption in the long term.
