Home backup battery cost in 2026

The 30% federal tax credit for home batteries ended with 2025. Here is what the latest quote data shows, what pushes a price up or down, and how to get a fair quote.

The short answer

EnergySage, which runs a large online marketplace for solar and battery quotes, reported that battery prices on its platform climbed to $1,130 per kWh of storage in the first half of 2026. It said the rise was partly driven by new "Foreign Entity of Concern" (FEOC) supply-chain rules. That is a quoted, installed price before any incentives.

Example only. Using that one figure: a 13.5 kWh battery (the usable capacity Tesla lists for Powerwall 3) x $1,130 per kWh = about $15,255. A 10 kWh battery would be about $11,300. Real quotes vary widely with the brand, your home and your installer, so treat this as a rough yardstick, not a price.

What changed in 2026: the tax credit

The IRS says the Residential Clean Energy Credit (often called the 25D credit) was worth 30% of the cost of qualified property, including battery storage, installed from 2022 through December 31, 2025. In the IRS's words: "The credit is not available for any property placed in service after December 31, 2025."

So a battery you buy and install in 2026 does not get that 30% federal credit. EnergySage notes the change came from the One Big Beautiful Bill Act (OBBBA), years earlier than many expected.

There is one route that still involves federal incentives. EnergySage reports that projects using third-party ownership, meaning a lease or a power purchase agreement (PPA) where a company owns the equipment on your home, can still qualify for federal incentives through 2027. The share of installers on its platform quoting these options rose from about 14% to about 41% during the first half of 2026. With a lease or PPA you do not own the system, so read the contract closely.

What drives the price

Capacity (kWh). More storage costs more. Work out what you need with our home backup battery calculator.
Power (kW). Running big loads like a well pump or central air needs more continuous output and surge, which may mean a larger or second battery.
Whole-home vs critical loads. Backing up only key circuits usually needs less battery than the whole house. See whole-home vs critical loads.
Electrical work. Some homes need a main panel upgrade, a new subpanel or long cable runs.
Labor. EnergySage says 74% of contractors in its 2026 survey reported higher labor rates this year, and that solar-plus-storage prices (not counting the battery itself) rose 5% from the second half of 2025.
Adding solar. EnergySage put the overall median solar price at $2.57 per watt before incentives in the first half of 2026. See is solar plus battery worth it?
Local incentives. Some states and utilities still pay for batteries. See home battery incentives.

Cheaper alternatives: portable and "home" power stations

Large portable power stations can cover some backup needs for less money, with less capacity and usually less power. Prices we read on the makers' own pages on Nov 1, 2026:

Product	Capacity (maker)	Price on maker's page
Jackery HomePower 3600 Plus	3,584 Wh	$1,899
Jackery Explorer 5000 Plus	5,040 Wh	$3,499
EcoFlow DELTA Pro Ultra (1 inverter + 1 battery)	6 kWh	$4,199

Prices checked Nov 1, 2026. Prices change often; these are not affiliate links. Transfer switches, extra batteries and electrician work cost extra. Both Jackery pages said the product was sold out and on pre-order when we checked.

These are not a like-for-like swap for an installed battery. Read can a power station back up your house? for the trade-offs, and see current offers on home battery deals.

How to get a fair quote

Get at least three quotes so you can compare price per kWh of usable capacity, not just the total.
Ask for an itemized quote: battery, gateway or backup switch, electrical work, permits and any panel upgrade.
Compare usable kWh and continuous kW from each battery's datasheet.
Check the warranty: years, and any energy-throughput or capacity limits. The FTC explains what to look for in a written warranty.
Ask about utility programs that pay you to share your battery with the grid. Some pay more than others; see the incentives page.
Read lease and PPA terms fully before signing, including what happens if you sell the house.

Is it worth it without the credit?

For pure backup, a battery is bought for peace of mind, much like a generator. Its value depends on how often your power goes out and what an outage costs you. For bill savings, it depends on your utility's rates, time-of-use pricing and how it pays for solar. EnergySage argues that rising utility rates and rate-structure changes are strengthening the case for storage; whether that holds for you depends on your own bills. We break this down in solar plus battery backup: is it worth it in 2026?
