Incentive types (tax credits, rebates, performance credits)
Solar incentives come in several forms:
- Federal tax credit: 30% of installed cost (2022–2032), then phases down. Reduces tax liability; may carry forward if credit exceeds taxes owed.
- State tax credits: Varies by state (some states offer credits, others don't). Check your state's current programs.
- Utility rebates: One-time payments or per-watt incentives. Availability varies by utility and may be limited or waitlisted.
- Performance credits: Payments based on energy production (SRECs in some states). Value varies by market and utility.
- Property tax exemptions: Some states exempt solar from property tax increases.
Incentives can significantly reduce net cost. Federal tax credit alone can reduce cost by 30%. State and utility incentives can add additional savings.
How to verify eligibility (timelines, paperwork)
Before signing a contract, verify your eligibility for incentives:
- Federal tax credit: Available to homeowners who own the system (not leases/PPAs). Must have tax liability to claim credit.
- State programs: Check your state's current incentives at DSIRE. Programs may have income limits, system size limits, or other requirements.
- Utility rebates: Contact your utility or check their website for current programs. Some programs have limited funding or waitlists.
- Timelines: Incentives may have expiration dates or phase-down schedules. Verify current status before signing.
- Paperwork: Keep all receipts, contracts, and documentation for tax purposes. Your installer should provide necessary forms.
Use the DSIRE database to search for incentives in your area. Verify eligibility with your installer and tax professional before signing.
Battery-specific incentives (if any; note variability)
Some states and utilities offer incentives specifically for battery storage:
- Federal tax credit: Batteries may qualify for federal tax credit if charged by solar (30% of battery cost).
- State rebates: Some states offer rebates for battery storage (e.g., California SGIP, Massachusetts SMART).
- Utility programs: Some utilities offer rebates or incentives for battery storage, especially for backup power or demand response.
Battery incentives vary widely by location and may change. Check current programs in your area before adding batteries to your system.
For more details, see our guide on solar batteries and backup.
Caution on changing policies (always verify before signing)
Incentive programs can change or expire:
- Federal tax credit: Phases down from 30% (2022–2032) to 26% (2033), 22% (2034), then expires (2035).
- State programs: May expire, change, or run out of funding. Verify current status before signing.
- Utility rebates: Often limited funding or waitlists. Programs may close or change terms.
- Performance credits: Market values can fluctuate. SREC prices vary by state and utility.
Always verify before signing: Check current incentive status with your installer, utility, and state energy office. Don't rely on outdated information or promises that incentives will be available.
Keep all documentation for tax purposes. Consult a tax professional to understand how incentives affect your tax situation.
FAQ
What's the federal solar tax credit
The federal solar tax credit is 30% of installed cost (2022–2032), then phases down to 26% (2033), 22% (2034), and expires (2035). You must own the system (not lease/PPA) and have tax liability to claim the credit.
Can I claim the tax credit if I lease
No. The federal tax credit applies only to systems you own. With leases and PPAs, the provider owns the system and claims the credit.
What if the credit exceeds my taxes
You can carry forward unused credit to future tax years. The credit doesn't expire until you use it, but you must have tax liability to claim it.
