## Quick answer

Do not trust an undated incentive claim in 2026. The federal 25D residential clean energy credit ended for installations completed after December 31, 2025 (Public Law 119-21), so a 2026 quote promising a simple 30 percent cash-buyer credit is a red flag until the installer shows a current source and date.

Do not trust an undated incentive claim in 2026.

The goal is not to pick the biggest battery. The goal is to understand what the quote includes, whether the design fits your outage pattern, and what the same usable capacity should cost in your market.

## What to compare first

| Line item | What to expect | Why it matters |
| --- | --- | --- |
| Cash or loan purchase | Verify current federal eligibility | Ask for the exact code section and placed-in-service rule |
| Lease or PPA | May be treated differently by the owner of the system | Ask who receives the credit and how it affects your payment. See [home battery financing](/guides/home-battery-financing-loan-vs-lease) for how loan dealer fees and lease terms compare. |
| State or utility programs | Highly local | Verify with DSIRE, utility pages, or state agencies |

## Quote red flags

- The quote says "30 percent back" with no date.
- The salesperson treats a tax credit as guaranteed cash.
- State incentives are listed but not tied to your utility territory.

## What to ask before signing

1. What is the installed price per usable kWh?
2. Which loads are backed up, and for how long?
3. Is this whole-home backup or essential-loads backup?
4. Is panel work included, excluded, or unknown?
5. Which incentive assumptions are included, and what is the effective date?

## Commercial note

Home Battery Guide may earn from affiliate links or flat-fee referrals to named vetted installers. Rankings do not move with compensation. We do not sell the same lead to multiple installers, and a referred installer quote still has to pass the same quote check.

## FAQ

### Can my installer promise my tax credit?
No. They can explain assumptions, but you need to verify eligibility with a tax professional and primary sources.

### Should incentive math be in the quote?
Yes. It should show gross price, incentive assumption, effective date, and net price separately.
