Residential Clean Energy Credit: Get 30% Back on Solar & Batteries
The federal Residential Clean Energy Credit is one of the most valuable tax incentives available to homeowners. Here's everything you need to know about claiming 30% back on solar panels, battery storage, and other clean energy investments.
Key Takeaways
- 30% tax credit with no annual dollar limit
- Covers solar, batteries, geothermal, and wind
- Unused credit carries forward to future tax years
- Can be combined with Massachusetts incentives for maximum savings
What Is the Residential Clean Energy Credit?
The Residential Clean Energy Credit, also known as the 25D credit (after Section 25D of the tax code), is a federal tax credit that rewards homeowners for installing renewable energy systems. It covers 30% of the total cost with no annual dollar limit—making it one of the most generous energy incentives available.
Originally passed in 2005 and significantly extended by the Inflation Reduction Act of 2022, this credit applies to solar panels, battery storage, geothermal heat pumps, small wind turbines, and fuel cells installed at your primary or secondary residence.
Key Advantage: Carry-Forward
Unlike the 25C credit, if your Residential Clean Energy Credit exceeds your tax liability, you can carry the unused portion forward to future tax years. This means you'll eventually receive the full benefit even if you can't use it all in one year.
What Qualifies for the 25D Credit?
The Residential Clean Energy Credit covers several categories of clean energy technology. Here's what qualifies:
Solar Energy
30%- Solar panels (photovoltaic)
- Solar water heating
- Installation and labor
- Permits and inspection fees
Battery Storage
30%- Battery systems 3+ kWh
- Must charge from renewable source
- Installation costs
- Works with or without solar
Wind Energy
30%- Small wind turbines
- Tower and mounting
- Installation costs
- For residential use
Geothermal Heat Pumps
30%- Ground source heat pumps
- Ground loop installation
- Indoor equipment
- Must meet Energy Star
Important: Battery Requirement
Standalone batteries only qualify if they're charged primarily (80%+) from renewable sources like solar. If you're adding a battery to an existing solar system or installing both together, you qualify. Grid-only batteries generally don't qualify.
Credit Amounts by Year
The Inflation Reduction Act set the Residential Clean Energy Credit at 30% through 2032, then gradually phases it down:
| Year | Credit Rate | Example: $25,000 System |
|---|---|---|
| 2022-2032 | 30% | $7,500 credit |
| 2033 | 26% | $6,500 credit |
| 2034 | 22% | $5,500 credit |
| 2035+ | Expires (unless extended) | $0 |
25C vs. 25D: What's the Difference?
The IRS offers two main residential energy tax credits, and understanding the difference is crucial for maximizing your savings:
| Feature | 25C (Efficiency) | 25D (Clean Energy) |
|---|---|---|
| Credit Rate | 30% | 30% |
| Annual Limit | $3,200 max | No limit |
| Carry-Forward | No | Yes |
| Covers | Heat pumps, insulation, windows, doors | Solar, batteries, geothermal, wind |
| Property Type | Primary residence only | Primary or secondary home |
You Can Claim Both!
The 25C and 25D credits are separate. You can claim the 25D credit for solar panels AND the 25C credit for a heat pump in the same year. They don't compete—they stack.
How to Claim the Residential Clean Energy Credit
Complete Your Installation
The system must be installed and operational before December 31 of the tax year you want to claim the credit. "Placed in service" means it's ready to use.
Gather Your Documentation
Keep these documents for your tax records:
- • Itemized invoice from installer
- • Manufacturer certifications
- • Proof of payment
- • Permit documentation
Complete IRS Form 5695
When you file your federal tax return, complete Part I of IRS Form 5695 (Residential Energy Credits). Enter your total costs and calculate the 30% credit.
Transfer to Form 1040
The credit amount from Form 5695 transfers to Schedule 3, then to your Form 1040, reducing your tax liability. If you have excess credit, it carries forward automatically.
Stacking with Massachusetts Incentives
Massachusetts residents can combine the Residential Clean Energy Credit with several state and utility incentives:
SMART Program
Ongoing per-kWh payments for solar generation. Rates vary by utility and system size.
Ongoing incentive paymentsConnectedSolutions
$225-$275/kWh annually for battery storage participating in demand response.
$2,500+/year for typical batteryMA State Tax Credit
15% state tax credit for solar installations, up to $1,000.
Up to $1,000Net Metering
Credit for excess solar electricity sent to the grid, reducing your electric bill.
Bill credits at retail rateMassachusetts Stacking Example: Solar + Battery
* Plus ongoing SMART payments and ConnectedSolutions payments in subsequent years.
The Bottom Line
The Residential Clean Energy Credit is one of the most valuable tax incentives available to homeowners. With 30% back on solar, batteries, and geothermal—plus no annual cap and carry-forward for unused credits—it makes clean energy investments significantly more affordable.
For Massachusetts residents, combining the federal credit with state programs like SMART and ConnectedSolutions can offset 40-60% of system costs. With electricity prices rising and the credit scheduled to phase down after 2032, 2026 is an excellent time to invest in clean energy.

Frequently Asked Questions
What is the Residential Clean Energy Credit?
The Residential Clean Energy Credit (Section 25D) is a federal tax credit that covers 30% of the cost of installing solar panels, battery storage, wind turbines, geothermal heat pumps, and fuel cells at your primary residence. Unlike the 25C credit, there is no annual dollar limit.
How much is the solar tax credit in 2026?
The federal solar tax credit is 30% in 2026. This applies to the total cost of your solar system including equipment, installation, permits, and sales tax. A $25,000 solar installation would receive a $7,500 tax credit.
Can I claim the Residential Clean Energy Credit on a rental property?
No. The 25D credit only applies to your primary residence or a second home that you personally use. Rental properties and investment properties do not qualify for this credit.
Is the 25D credit refundable?
No, but unlike the 25C credit, unused portions of the 25D credit CAN be carried forward to future tax years. If your tax liability is less than your credit, you can use the remaining credit in subsequent years until it's exhausted.
What's the difference between 25C and 25D credits?
The 25C credit (Energy Efficient Home Improvement Credit) covers efficiency upgrades like heat pumps, insulation, and windows with annual caps ($3,200 max). The 25D credit (Residential Clean Energy Credit) covers clean energy generation like solar and batteries with no annual cap but no carry-forward for unused credits.
