Battery storage prices statistics: U.S. residential quote trends and shopper interest
EnergySage reported that median storage prices in its marketplace transaction data increased 5% in the first half of 2026 (H1 2026). The period covers January 1 through June 30, 2026. This is a change in the platform’s median storage price, not a national average of every residential battery installation. The same report said median solar prices increased 3% over that period, providing context for the movement in combined solar-and-storage shopping. EnergySage Marketplace Report
The report also described strong interest alongside a lower rate of battery attachment. Self-reported homeowner interest in battery storage reached 76% in H1 2026, while battery attachment on EnergySage was 31%. These figures describe different platform measures: reported interest is not the same as a shopper proceeding with a battery alongside solar. Neither percentage should be read as the share of all U.S. households that own a battery or plan to buy one. EnergySage Marketplace Report
Taken together, these indicators describe a marketplace where battery interest was widespread among participating homeowners, even as attachment remained a smaller measured share. The report characterized storage affordability as a hurdle. The figures do not establish why any individual homeowner did or did not add a battery, and they do not measure national adoption outside the EnergySage marketplace. EnergySage Marketplace Report
Battery storage prices statistics: state-by-state home battery quotes
EnergySage’s state table reports average battery price per kWh for H1 2026 marketplace quotes. The table’s scope is state-specific EnergySage pricing, and its footnote defines the period as the first half of 2026. The figures are quote averages rather than a census of completed installations; they provide a view of the platform’s reported price levels across the listed locations. EnergySage battery cost by state
| State or district | Average price per kWh, H1 2026 |
|---|---|
| Alabama | $563 |
| Arkansas | $761 |
| Hawaii | $789 |
| District of Columbia | $873 |
| Nebraska | $910 |
| North Dakota | $920 |
| Florida | $1,005 |
| Arizona | $1,019 |
| New Jersey | $1,038 |
| New Hampshire | $1,089 |
| California | $1,079 |
| Missouri | $1,109 |
| Montana | $1,115 |
| Connecticut | $1,153 |
| Delaware | $1,153 |
| Minnesota | $1,155 |
| Maine | $1,171 |
| Kansas | $1,193 |
| Illinois | $1,240 |
| North Carolina | $1,241 |
| Iowa | $1,263 |
| Colorado | $1,261 |
| Georgia | $1,278 |
| Idaho | $1,301 |
| Mississippi | $1,323 |
| Maryland | $1,341 |
| Massachusetts | $1,352 |
| Michigan | $1,364 |
| Kentucky | $1,494 |
| New Mexico | $1,561 |
| Louisiana | $1,586 |
| Indiana | $1,333 |
The state values show substantial variation in this excerpt of the table, from Alabama’s $563 per kWh to Louisiana’s $1,586 per kWh. These endpoints are observations from the listed marketplace prices, not national minimum and maximum installation costs. Cost comparisons should retain the per-kWh denominator and the H1 2026 quote period; the table’s averages do not imply that every quote or system in a state had that price. EnergySage battery cost by state
California’s $1,079 per kWh is one state marketplace average in the same table. It should not be equated with the separate California historical benchmark below, which measures an entire PV-plus-storage system per battery kWh and uses a different population and price basis.

Battery storage prices statistics: California residential PV-plus-storage benchmarks
A separate historical series from the National Renewable Energy Laboratory reports median prices for residential rooftop PV-plus-storage systems in California. The measure is total system price normalized per kWh of battery, expressed in 2024 dollars. Included rooftop PV systems fall within a 3–30 kWdc range. Because the numerator includes the PV-plus-storage system, these are not battery-only prices and should not be directly compared with EnergySage’s battery quote averages. NREL, Spring 2025 Solar Industry Update, p. 59
| Installation year | Median total PV-plus-storage system price per battery kWh, 2024 dollars |
|---|---|
| 2018 | $2,831 |
| 2019 | $3,372 |
| 2020 | $2,387 |
| 2021 | $2,319 |
| 2022 | $2,742 |
| 2023 | $2,812 |
| 2024 | $3,074 |
The annual median series does not move in a single direction. The reported value rises from $2,831 in 2018 to $3,372 in 2019, then is $2,387 in 2020 and $2,319 in 2021. It increases to $2,742 in 2022, $2,812 in 2023 and $3,074 in 2024. Each number is a median for that installation year under the stated system filter and dollar basis; the observations alone do not explain the year-to-year changes. NREL, Spring 2025 Solar Industry Update, p. 59
The distinction between a system price per battery kWh and a battery-only price matters when reading price statistics. A PV-plus-storage benchmark combines the cost basis of a broader installed system and divides it by battery capacity. EnergySage’s state table, by contrast, presents average battery pricing per kWh on its marketplace. The two datasets answer different questions, despite using a kWh denominator.

Battery storage prices statistics: EnergySage battery brand quotes
EnergySage’s H1 2026 brand table gives average price per kWh and typical battery size for the 10 most quoted batteries on the platform. The listed capacity is median usable capacity. The prices are platform averages for that period, and the capacities describe typical usable size; neither field should be generalized to every product or quote from a company. EnergySage cost of top battery brands
| Battery company | Average price per kWh, H1 2026 | Typical battery size, kWh |
|---|---|---|
| MidNite Solar | $342 | 16 |
| Canadian Solar Inc. | $654 | 10 |
| Fox ESS | $782 | 14.3 |
| Tesla | $967 | 13.5 |
| Sigenergy | $1,028 | 15.4 |
| EG4 | $1,149 | 12.9 |
| FranklinWH Energy Storage Inc. | $1,232 | 15 |
| EcoFlow Technology Inc | $1,365 | 9.5 |
| Enphase Energy | $1,429 | 10 |
| APsystems | $1,648 | 10.2 |
The displayed average prices span $342 per kWh for MidNite Solar to $1,648 per kWh for APsystems. Listed typical battery sizes range from 9.5 kWh for EcoFlow Technology Inc to 16 kWh for MidNite Solar. Price per kWh and usable capacity describe different aspects of the table: one is a unit price, while the other is a capacity measure. Brand rows therefore offer useful examples of marketplace variation, but they do not establish a like-for-like product comparison across specifications or quote configurations.

Battery storage prices statistics: residential battery price and capacity examples
EnergySage states that solar batteries typically cost $15,647 before available incentives for 13.5 kWh of storage, a capacity it describes as typical for a home. The article was updated July 13, 2026. This is a typical-cost statement and capacity example, not a guarantee that a particular household will receive a quote at that total. System design and the selected battery are outside the scope of this single reported example. EnergySage solar battery cost guide
The same guide says equipment costs typically account for 50–60% of an energy storage system’s price. That proportion refers to equipment’s share of system price; it is not itself a battery price or a separate estimate of the total installed cost. It helps distinguish the equipment component from the broader system figure, while leaving the specific cost breakdown for an individual project undetermined. EnergySage solar battery cost guide
EnergySage also gives about $34,000 as the cost of whole-home backup battery storage. The guide places this example in a discussion of how much battery storage a home may need. It is an approximate whole-home backup figure, distinct in scope from the $15,647 typical battery cost statement and its 13.5 kWh capacity. The two examples describe different storage needs and should not be treated as interchangeable price points. EnergySage solar battery cost guide
For readers comparing these residential examples with marketplace statistics, three indicators help keep the measures straight: the 5% H1 2026 median storage-price increase and 76% reported interest describe EnergySage shopper activity; state and brand tables report marketplace price observations per kWh; and the California historical series is a median total PV-plus-storage system price per battery kWh in 2024 dollars. The typical-home and whole-home figures are separate cost examples, not substitutes for those averages or historical medians.
