Understanding Solar Incentives in 2025

Solar incentives come in various forms, from tax credits to rebates and performance-based incentives. These programs are designed to encourage renewable energy adoption by reducing the upfront costs and improving the long-term economics of solar installations. As a DIY solar installer, taking advantage of these incentives can significantly impact your project’s financial viability.

Federal Solar Tax Credit (ITC) Explained

The federal solar Investment Tax Credit (ITC) is the most valuable incentive available to homeowners installing solar power systems.

Current Status and Political Uncertainty

As of March 12, 2025, the federal solar tax credit remains available at 30%, despite recent headlines about the Trump Administration ordering a pause on funding for the Inflation Reduction Act. The funding for this year’s tax credit has already been approved by Congress, making it difficult to change. However, the executive order is facing legal challenges in several states, creating some uncertainty about the program’s future beyond 2025.

If you’re considering a solar installation, the current political climate suggests acting sooner rather than later to ensure you can claim these incentives.

How the Federal Solar Tax Credit Works

The federal solar tax credit allows you to deduct 30% of the cost of installing a solar energy system from your federal taxes. This is a dollar-for-dollar reduction in what you owe in taxes, not just a deduction from your taxable income.

For example, if your solar installation costs $20,000, you can claim a $6,000 tax credit on your federal tax return. According to EnergySage data, the average 11kW system costs $29,360 before incentives, resulting in an $8,808 tax credit and bringing the net cost down to $20,552.

The tax credit is nonrefundable, meaning it can reduce your tax liability to zero but won’t result in a refund. However, if your tax liability is less than the credit amount, you can roll over the remaining credit to future tax years.

Current Timeline

The federal solar tax credit will remain at 30% through 2032, then step down according to this schedule:

Year	Tax Credit Percentage
2025-2032	30%
2033	26%
2034	22%
2035 and beyond	0% (expires)

Qualifying for the Federal Solar Tax Credit

To be eligible for the federal solar tax credit in 2025, you must meet these requirements:

System Ownership: You must own the solar system. You are not eligible if you lease your system or enter a power purchase agreement (PPA).
Installation Location: The system must be installed at your primary or secondary residence in the United States.
Installation Timing: The system must be installed and operational within the tax year for which you’re claiming the credit.
Tax Liability: You must have sufficient tax liability to claim the credit, though unused credits can roll over to future years.

Eligible Expenses

The federal tax credit covers a comprehensive array of expenses related to your solar installation:

Solar panels and solar shingles
Inverters (string, micro, or hybrid)
Battery storage systems (3 kWh capacity or greater)
Mounting hardware and racking
Wiring and electrical components
Installation labor costs
Permitting fees and inspection costs
Sales tax on eligible expenses

How to Claim the Federal Solar Tax Credit

Claiming the solar tax credit involves these steps:

Complete IRS Form 5695 (Residential Energy Credits)
Calculate your credit amount (30% of total eligible costs)
Transfer the credit amount to your Form 1040
File with your annual tax return by April 15, 2025

Keep detailed records of all costs associated with your solar installation, including receipts, contracts, and manufacturer certifications. While you don’t need to submit these documents with your tax return, you should keep them on file in case of an audit.

State and Local Solar Incentives

Beyond the federal tax credit, many states and local utilities offer additional incentives that can further reduce your solar costs.

State Tax Credits and Rebates

Many states offer their own tax credits or rebates for solar installations. For example:

New York: Combines the NY-Sun program, property tax exemptions, and state solar tax credit to reduce solar investments by up to 60%
California: Offers various rebate programs and property tax exclusions
New Jersey: Provides performance-based incentives and property tax exemptions

Types of State and Local Incentives

Solar incentives typically fall into three categories:

Tax breaks: Income tax credits, sales tax exemptions, and property tax exemptions
Rebates: Direct cash incentives that reduce upfront costs, usually offered by utility companies
Performance payments: Ongoing payments based on the amount of energy your system generates

Net Metering Programs

Net metering allows you to receive credit for excess electricity your system produces and sends back to the grid. While not a direct financial incentive, net metering can significantly improve the economics of your solar system by essentially using the grid as free storage.

Maximizing Your Solar Incentives

To get the most value from available incentives, follow these strategies:

Research All Available Programs

Before installing your system, research all incentives available in your area:

Federal tax credit
State tax credits and rebates
Local utility incentives
Property tax exemptions
Sales tax exemptions
Performance-based incentives

The Database of State Incentives for Renewables & Efficiency (DSIRE) is an excellent resource for finding programs in your area.

Timing Your Installation

Given the current political uncertainty surrounding the Inflation Reduction Act funding:

Consider installing sooner rather than later to ensure eligibility
Be aware that many installers are seeing a surge in demand due to this uncertainty
Remember that the 2025 tax credit is secure, but future years may be less certain

Conclusion

Solar power represents a smart financial move for homeowners willing to navigate the available incentives. The federal solar tax credit stands as your greatest ally, offering a substantial 30% reduction on your total installation costs through 2032. This translates to approximately $10,000 in savings for the average 11kW system, dramatically improving your return on investment.

Taking advantage of these benefits requires understanding the qualification requirements. You must own your system outright, install it at your primary or secondary residence, and have it operational within the tax year you’re claiming. Remember that eligible expenses extend beyond just panels to include inverters, batteries, mounting hardware, and installation costs—maximizing your potential savings.

The current political climate creates a sense of urgency for solar enthusiasts. While the 2025 tax credit remains secure, future funding faces uncertainty. Combining federal incentives with state programs can reduce your investment by up to 60% in places like New York, making this an opportune moment to act rather than wait.

For DIY installers, thorough research and documentation are essential steps in your solar journey. Investigate all available programs in your area using resources like the Database of State Incentives for Renewables & Efficiency, and maintain detailed records of every expense. With proper planning, your solar project can deliver both environmental benefits and significant financial returns that make the initial investment worthwhile.

By harnessing both sunlight and incentives, you’re not just generating clean electricity—you’re making a financially sound decision that pays dividends through reduced utility bills and increased property value for decades.

FAQ

How does the federal solar tax credit work in 2025?

The federal solar tax credit, also known as the Investment Tax Credit (ITC), allows homeowners to claim 30% of their solar system costs as a tax credit on their federal tax returns. This is a dollar-for-dollar reduction in your tax bill, with no cap on the amount you can claim. For example, if your solar installation costs $25,000, you would receive a $7,500 tax credit that directly reduces your federal tax liability.

Is the federal solar tax credit still available in 2025?

Yes, the federal solar tax credit is still available in 2025 at the 30% rate. Despite recent political changes and executive orders from the Trump administration, the funding for this year’s tax credit has already been approved by Congress. The tax credit is currently scheduled to remain at 30% until 2032, after which it will drop to 26% in 2033 and 22% in 2034, before expiring completely in 2035.

How has the political landscape affected solar incentives?

The current Republican-led administration and Congress have created uncertainty for the future of solar incentives. President Trump issued an executive order suspending some Inflation Reduction Act (IRA) funding for renewable projects for 90 days pending review. While this has affected some complementary funding mechanisms, the 2025 solar tax credit itself remains in effect. This uncertainty has actually driven a surge in solar installations as homeowners rush to secure the full 30% credit while it’s still available.

What costs qualify for the federal solar tax credit?

Eligible expenses for the federal solar tax credit include:

Solar PV panels and solar shingles
Battery storage systems (minimum 3 kWh capacity)
Installation labor costs
Permitting fees and inspection costs
Wiring, inverters, and mounting equipment
Sales taxes on eligible expenses
System upgrades like electrical panel improvements related to your solar installation

Who qualifies for the solar tax credit?

To qualify for the federal solar tax credit, you must:

Own your solar system (not lease it or have a power purchase agreement)
Have sufficient tax liability (though unused credits can roll forward)
Install the system at your primary or secondary residence (rental properties don’t qualify)
Be the original installer of the equipment (used panels don’t qualify)

How do I claim the solar tax credit on my taxes?

To claim the federal solar tax credit:

Save all receipts and documentation related to your solar installation
Complete IRS Form 5695 (Residential Energy Credits)
Calculate your credit (30% of total eligible costs)
Transfer the credit amount to Schedule 3 and Form 1040
File with your annual tax return

The credit applies to the tax year in which your system receives Permission to Operate (PTO) from your utility company, not when you purchased it.

What state-level solar incentives are available in 2025?

In addition to the federal tax credit, many states offer their own incentives:

Property tax exemptions (available in states like Florida, Missouri, and California)
Sales tax exemptions (offered in states like Alabama, Florida, and Texas)
Net metering programs (available in numerous states including California, Florida, and South Carolina)
State-specific tax credits and rebates
Solar Renewable Energy Credits (SRECs) in states like Delaware, Illinois, Maryland, and Massachusetts

What happens if I don’t have enough tax liability to claim the full credit?

If your tax liability is less than your solar tax credit amount, you can carry forward the unused portion of the credit to future tax years. This allows you to claim the remaining credit when you have sufficient tax liability, ensuring you don’t lose out on the benefit.

Can I claim the solar tax credit for a battery installation?

Yes, standalone battery storage systems with a minimum capacity of 3 kilowatt-hours (kWh) qualify for the 30% tax credit as of 2023. If you previously installed solar panels and now want to add a battery system, the battery costs are eligible for the tax credit.

How might solar incentives change in the future?

There’s significant uncertainty about the future of solar incentives beyond 2025. Possible scenarios include:

An early phase-out of the solar tax credit starting in 2026 or 2027
New requirements tying tax credit eligibility to domestic content thresholds
Potential termination of the IRA through repeal
However, projects built in 2025 will most likely still qualify for the current incentives, as retroactive changes would face substantial legal challenges
