Brooklyn's price band
Brooklyn is pricier than 68% of the 195 US metros we price for home battery work.
A Powerwall 3-size battery in Brooklyn starts near $11,350 installed, sits at $14,550 for a typical job and reaches $18,300 when the panel, wiring or access is hard. An expansion unit adds $4,950–$7,900 at install time.
EnergySage's first-half-2026 quotes in New York averaged $888 per kWh before incentives, about $12,000 for a typical 13.5 kWh system. That was well under the national average of $1,159. New York's NYSERDA pays rebates on grid-connected home batteries up to 25 kWh: $250 per kWh in Con Edison and Long Island areas, $200 per kWh in the rest of the state and $450 per kWh for lower-income homes, released in first-come blocks that step down over time (as of September 2026).
Every price here is before incentives, and there is no federal one left: the 30% credit for home batteries ended for expenditures after December 31, 2025, and the IRS treats the expense as made when the install is complete. Check your utility for a battery or demand-response program before you sign.

Prices cover the Brooklyn metro and assume one 13.5 kWh battery mounted on a garage or outside wall. Older homes in Williamsburg & Greenpoint more often need panel work.
Home battery prices across Brooklyn
The battery costs the same across Brooklyn; the house around it does not. Older wiring in Downtown Brooklyn & Park Slope pushes labor up, and garage installs in South & East Brooklyn keep it down.
Williamsburg & Greenpoint
- Installed
- $11,800–$18,650 installed
- Typical job
- $12,850–$22,200 / one battery + whole-home backup
Character homes and older wiring. The battery price is standard; the add-ons (panel, subpanel, longer wire runs) decide the final number.
Bushwick & Bed-Stuy
- Installed
- $11,800–$18,650 installed
- Typical job
- $12,850–$22,200 / one battery + whole-home backup
Mixed older housing. Many homes need a subpanel for partial backup; the battery price is standard but the electrical work varies.
Downtown Brooklyn & Park Slope
- Installed
- $12,250–$19,400 installed
- Typical job
- $13,350–$23,050 / one battery + whole-home backup
Dense blocks with older panels and little wall space. Expect an outdoor-wall install, a longer permit review and parking folded into the labor line.
South & East Brooklyn
- Installed
- $11,000–$17,550 installed
- Typical job
- $11,950–$20,900 / one battery + whole-home backup
The edges of the metro: longer drives, more homes on wells, and backup needs that can call for a bigger system.
Real home battery jobs in Brooklyn
Here's what common home battery jobs cost in Brooklyn in 2026, installed, before incentives.
Essentials backup: one battery + critical-loads panel
Fridge, furnace fan, lights, Wi-Fi and a few outlets on one 13.5 kWh battery. The battery is $11,350–$18,300 installed; moving those circuits to a critical-loads subpanel adds $390–$1,750.
Whole-home backup: one battery + gateway
A whole-home gateway or transfer switch ($990–$3,450) lets one battery run the whole panel during an outage. Central AC or a well pump may still need a second battery to start reliably.
Bigger home: two batteries
27–30 kWh for larger homes or longer outages. A Powerwall 3 plus an expansion unit sits at the low end; two full units or two FranklinWH aPower 2s sit at the top.
Adding a battery to solar you already have
An AC-coupled battery works next to your existing inverter. Expect $11,850–$15,050 for a straightforward job; older inverters or a full panel push it toward $19,250.
Older home: battery + panel upgrade
Many 100-amp panels have no room for a battery. Going to 200 amps adds $1,500–$4,450 in Brooklyn, and doing it with the battery means one permit and one inspection.
How much does a home battery cost in Brooklyn?
Between $11,350 and $18,300 for one 13.5 kWh battery, installed, and most Brooklyn homeowners pay close to $14,550. Three things set the number: how much of the house you back up, whether the panel needs work, and the brand. Partial backup on a good 200-amp panel lands near the low end; whole-home backup with a gateway and a panel upgrade can pass $20,100.
There is no federal credit to take off these numbers any more. What can still cut the bill in Brooklyn is a utility or state battery program, a second bid, and not buying more battery than you need. Two batteries ($16,300–$33,550) is more than many homes need. Figures re-verified against 57 sources in November 2026.
Home battery prices in Brooklyn (2026): the lines on a quote
One battery is $11,350–$18,300 installed, whole-home backup adds $990–$3,450, and a panel upgrade adds $1,500–$4,450.
| Line on the quote | Low | Typical | High |
|---|---|---|---|
| Tesla Powerwall 3 (13.5 kWh), installed | $11,350 | $14,550 | $18,300 |
| Expansion unit, added at install | $4,950 | $6,450 | $7,900 |
| Whole-home backup gateway | $990 | $1,800 | $3,450 |
| Critical-loads subpanel | $390 | $990 | $1,750 |
| Main panel upgrade (100A to 200A) | $1,500 | $2,450 | $4,450 |
| Permit and utility fees | $150 | $450 | $990 |
| Battery service visit | $150 | $350 | $790 |
| Standby generator, 20–24 kW (comparison) | $8,400 | $11,400 | $15,850 |
The battery is the biggest line, but it is not where Brooklyn quotes differ most. Compare the gateway, panel and permit lines; one bid may include all three and another none.
What moves a home battery quote in Brooklyn:
- Backup level — partial backup on a backup switch is cheapest; whole-home backup adds a gateway and often a second battery.
- The panel — a full or 100-amp panel can add $1,500–$4,450 for an upgrade.
- Where it mounts — a garage or outside wall near the panel is cheapest; long wire runs and trenching add labor.
- Brand and size — a 5 kWh Enphase unit and a 15 kWh FranklinWH are very different checks.
- Permits and the utility — $150–$990 in fees, plus the wait for permission to operate.
Ask every Brooklyn installer for the same four things: the battery price, the backup equipment (switch, gateway or subpanel), the panel work, and permit and utility fees. Compare those lines, not the total. Get a quote for your battery install →
Home Battery Cost in Brooklyn by Backup Level
Essentials backup on one battery is $11,350–$18,300, whole-home backup with a gateway is $12,350–$21,750, and two batteries for a larger home are $16,300–$33,550, before any utility incentive.
Worked example: a Brooklyn home with a 200-amp panel and a garage wall next to it gets one Powerwall 3 at $14,550 plus a whole-home gateway at $1,800: $16,350. The same house with a 100-amp panel adds an upgrade at $2,450, for $18,800.
A larger home that wants central AC on backup usually needs two batteries ($22,700 typical) plus the gateway, about $24,500. For comparison, a 20–24 kW standby generator runs $8,400–$15,850 installed in Brooklyn, plus fuel.

Battery vs installation: where a Brooklyn quote goes
The battery itself is about $8,200–$10,000 for a Powerwall 3 anywhere in the US. On a $14,550 Brooklyn job that leaves roughly $5,450 for labor, wiring, the backup switch or gateway, permits and the utility paperwork.
That is why Brooklyn bids for the same battery can sit $6,950 apart. One installer's $14,550 may include a whole-home gateway and permit fees; another's $13,400 may not. Line up the items before you compare totals.
What's included in a Brooklyn battery quote (and what costs extra)
A standard quote covers the battery, mounting, wiring to your panel, a basic backup switch, commissioning and the app setup. The headline price often leaves out:
- Whole-home backup gateway — $990–$3,450 if you want the whole panel backed up
- Panel upgrade — $1,500–$4,450 to go from 100 to 200 amps
- Critical-loads subpanel — $390–$1,750 for partial backup on older panels
- Permit and utility fees — $150–$990, plus bollards or a heat alarm if the battery goes in a garage
Ask for the warranty terms in writing: years, capacity guaranteed at the end, and who services the battery locally.
Your local market
Brooklyn is a big metro where battery installs run above the US typical. The hardware price is national; labor, permits and how many installers compete for the job are local, and they decide whether a quote lands nearer $11,350 or $18,300.
How much of the house you back up
Partial backup on one battery is $11,350–$18,300. Whole-home backup adds a gateway ($990–$3,450) and, in bigger homes, a second battery.
Your electrical panel
A crowded or 100-amp panel is the most common surprise. Upgrading to 200 amps adds $1,500–$4,450 in Brooklyn; a critical-loads subpanel adds $390–$1,750.
Where the battery goes
Garages and outside walls are the usual spots. Model codes keep batteries out of bedrooms and living space, cap garage installs at 80 kWh, and call for impact protection where a car could hit the unit.
Brand and capacity
An Enphase IQ 5P is $5,950–$8,900 per 5 kWh unit, a Powerwall 3 $11,350–$18,300 for 13.5 kWh, and a FranklinWH aPower 2 $14,300–$22,700 for 15 kWh.
Solar or no solar
A battery added to existing solar is $11,850–$19,250; a grid-charged battery with no solar is $11,350–$18,300. A battery installed with new solar shares one permit and one crew.
Permits and the utility in Brooklyn
Expect $150–$990 in permit and interconnection fees and a wait for the utility's permission to operate if the battery ties into solar.
- Get two or three bids.Same battery, different labor lines. Brooklyn quotes for one 13.5 kWh battery run $11,350–$18,300; a second bid is the fastest way to find the padding.
- Back up the essentials, not the whole house.A critical-loads subpanel ($390–$1,750) keeps one battery on the circuits that matter. A second battery costs $8,900–$12,350.
- Ask about your utility's battery program.NYSERDA pays $200–$250 per kWh on grid-connected home batteries up to 25 kWh ($450 per kWh for lower-income homes), in regional blocks that step down (as of September 2026). Programs that pay you to share the battery at peak times can return a few hundred dollars a year or more.
- Add storage at install time.An expansion unit added with the first battery is $4,950–$7,900. Coming back later means a second trip, a second permit and often a second full battery.
- Do the panel work with the battery.A 200-amp upgrade ($1,500–$4,450) done in the same job shares the permit, the inspection and the utility visit.
- Read the warranty before you pick a brand.Powerwall 3 and SolarEdge carry 10 years at 70% capacity; Enphase and FranklinWH carry 15 years. A longer warranty can be worth a higher price.
Before you pay a deposit to a Brooklyn installer, get these in writing:
- The battery brand, model and usable kWh
- Backup type: partial (backup switch or subpanel) or whole-home (gateway)
- Any panel upgrade or subpanel, priced as its own line
- Where the battery mounts, and any bollards or heat alarm the code needs
- Permit, inspection and utility interconnection fees
- Warranty: years, capacity guaranteed and who services it locally
- Monitoring app setup and any utility program enrollment
- Payment schedule, and what happens if the utility approval is delayed

Enphase IQ Battery 5P: $5,950–$8,900 per 5 kWh unit; IQ Battery 10C: $10,850–$16,800. FranklinWH aPower 2 (15 kWh): $14,300–$22,700, installed.
What permits does a home battery need in Brooklyn?
An electrical permit at minimum, often a building or fire review, and your utility's approval if the battery ties into solar or can send power to the grid. Fees run $150–$990. Garage installs may need a heat alarm and bollards.
How long does a home battery last, and what does upkeep cost?
Warranties run 10 years (Powerwall 3, SolarEdge) to 15 years (Enphase, FranklinWH), guaranteeing 60–70% capacity at the end. Upkeep is mostly app monitoring; a service visit costs $150–$790 once the warranty is over.
