Powerwall 3 starting from $19,999$9,799
Price for a standard installation.
Battery + full professional installation for California homes.
Backup power through outages and lower peak-rate bills.
The battery that keeps your home on autopilot.
Powerwall 3 is the next-generation home battery that gives California homes reliable backup power and smarter use of every kilowatt-hour you buy or produce.
How your battery works
Three situations, one consistent promise: your home always comes first.
Running in the background
Your Powerwall quietly charges when your utility's rates are cheapest and powers your home during expensive peak hours. Monitor everything in real time from the Tesla app.
Powerwall intelligence
It doesn't just store energy — it decides when to use it.
Powerwall 3 watches weather alerts, utility rates and your home's usage around the clock, then acts on its own. You just get the savings and the lights staying on.
Storm Watch
When the National Weather Service issues a severe weather alert for your area, Powerwall automatically charges to full so you're at 100% before the grid goes down.
Starts the big loads
Powerwall 3 delivers 11.5 kW continuous and can start heavy motors up to 185 A LRA — so one unit can typically kick on an AC compressor, well pump or heat pump during an outage.
Expandable to 4 units
Start with one Powerwall and add up to three more later for whole-home backup, longer outage coverage or an EV charger, without replacing what you already own.
You control it from your phone
Choose Time-Based Control to arbitrage peak rates, Backup-Only to hold a full reserve, or Self-Powered — and watch live energy flows in the Tesla app.
Built for California weather
Water and dust resistant with an operating range of -4°F to 122°F, so it mounts indoors or outdoors — garage wall, side yard, or under an eave.
Quiet and maintenance-free
No fuel, no oil changes, no annual service. The inverter is built in, so there's one sleek unit on the wall instead of a rack of equipment.
See every watt in the Tesla app
Set your backup reserve, switch operational modes, and watch live energy flow between the grid, your home and your Powerwall — from anywhere. Savings mode uses your utility rate plan to decide when to charge and when to discharge, automatically.

Why a battery beats a generator
California's grid keeps getting less predictable. Your power shouldn't.
Between public safety power shutoffs, storm outages and rising time-of-use rates, backup power has stopped being a luxury. A Powerwall protects your home and pays you back the other 364 days of the year.
Hours of backup, not minutes
One Powerwall carries the essentials — fridge, lights, Wi-Fi, medical devices — through a typical PSPS or storm outage. Stack a second unit to keep AC and an EV charger running too.
It switches over automatically
No cords, no manual transfer switch, nothing to start. The Backup Gateway detects the outage and your home keeps running in a fraction of a second — even when you're not home.
Silent and emission-free
A generator is loud, needs servicing and only runs during outages. A Powerwall is silent, sits flush on a wall or garage, and saves you money every single day.
No fuel to store or refill
Nothing to haul, spill or stabilize. The battery refills itself from off-peak grid power or your solar array, so it's always full when the grid goes down.
One partner, start to finish
Design, permitting, utility interconnection, installation and Tesla app setup all handled by SolarSesame — plus workmanship coverage after the truck leaves.
Monitored and future-proof
Track usage, backup reserve and VPP events from your phone. Over-the-air updates keep adding features long after install day.
No solar panels? You can still get a Powerwall.
A Powerwall 3 does not require an existing solar system. Most of our battery customers start with storage alone — and many never add panels at all.
- Install a Powerwall on its own — no panels, no roof work, no re-roofing required.
- Charge it from the grid at off-peak rates and run your home during expensive peak hours.
- Powerwall owners with or without solar can qualify for virtual power plant programs such as Tesla's with PG&E, subject to eligibility including a valid Rule 21 interconnection agreement.
- Add solar panels later — Powerwall 3 already has the solar inverter built in, so you're ready when you are.
Is Powerwall right for your home?
If any of these sound familiar, a battery may make more sense than you think.
You already have solar, but no battery
Your panels produce the most electricity during the day, but your home may need more energy in the evening.
Keep more of the solar you already produce.
Your newer home came with builder-installed solar
Thousands of newer California homes were built with solar, but that doesn't mean they received battery storage.
Your home came with solar. Now make it work after sunset.
Your electric bill is still too high
Even with solar, you may still buy expensive electricity during evening peak periods.
Buy less electricity when it's most expensive.
Calculate what Powerwall could save me →You're worried about power outages
An outage can shut down your refrigerator, Wi-Fi, lights, security system, garage, AC and other important equipment.
When the grid goes down, your home doesn't have to.
You're considering a generator
Generators require fuel, maintenance and manual considerations, and they provide essentially no financial benefit while the grid is operating.
Don't buy backup power that only works when the power goes out.
Your home is becoming more electric
EVs, AC, heat pumps, pools and other large loads can significantly increase household electricity demand.
EV. Pool. AC. Heat pump. Your home uses more electricity than it used to.
Sound like your home?
We'll look at your solar system, utility, rate plan and electricity usage to estimate what Powerwall could actually do for you.
Two ways one Powerwall pays you back
Save — buy power when it's cheap and use it when it's expensive. Earn — get paid when your battery supports the grid. The sections below break down both, then you can run your own numbers.
Time-of-use bill savings
$350–$900/yr
PG&E ~$350–$600 · SCE ~$500–$900 per year
Tesla VPP earnings
$100–$450/yr
Paid $2.00/kWh when your battery supports the grid
Combined potential value
$450–$1,350/yr
Per Powerwall, per year, depending on your utility
Ranges are potential, not guaranteed. Actual results depend heavily on your usage pattern, rate plan, number of VPP events and how frequently the battery cycles.
Buy power cheap. Use it when it's expensive.
Your Powerwall charges when rates are lowest and powers your home through the expensive evening peak. Pick your utility to see the numbers.
PG&E — Sample time-of-use plan
- One full 13.5 kWh cycle a day is roughly $1.66 of avoided peak cost.
- That's about $50 a month, or up to ~$606 a year in theory.
- After real-world round-trip efficiency (~89%), plan on ~$350–$600 a year.
- Works with or without solar panels — the grid can do the charging.
The math, one Powerwall on PG&E
| Peak rate | $0.5224 / kWh |
| Off-peak rate | $0.3994 / kWh |
| Spread you capture | $0.123 / kWh |
| Usable capacity shifted | 13.5 kWh/day |
| Daily savings | ~$1.66 |
| Monthly savings | ~$50 |
| Realistic annual savings | $350–$600 |
Based on sample PG&E time-of-use rates and ~89% round-trip efficiency. Actual savings depend on your rate plan, usage pattern and how often the battery fully cycles.
SCE — TOU-D-5-8PM / TOU-D-4-9PM (delivery + generation)
- SCE's summer peak window (4–9pm) is the most expensive power in California — that's exactly when your Powerwall takes over.
- Combining delivery and generation charges, summer peak runs about $0.74/kWh vs $0.34/kWh off-peak.
- In winter, shifting from mid-peak to super off-peak still captures about 17.5¢/kWh.
- Realistically, most SCE homes see ~$500–$900 a year from one Powerwall.
The math, one Powerwall on SCE
| Summer on-peak (4–9pm) | $0.7379 / kWh |
| Summer off-peak | $0.3394 / kWh |
| Summer spread | $0.398 / kWh |
| Winter mid-peak vs super off-peak | $0.175 / kWh |
| Usable capacity shifted | 13.5 kWh/day |
| Summer daily savings | ~$4.79 |
| Realistic annual savings | $500–$900 |
Based on a real SCE TOU-D bill (summer on-peak $0.32633 delivery + $0.41155 generation; off-peak $0.27640 + $0.06298) and ~89% round-trip efficiency. Peak windows are only 4–9pm, so actual savings depend on how much of your usage falls in that window.
On SDG&E or a municipal utility? The same strategy applies — send us a recent bill and we'll model the savings on your exact rate plan.
Get paid when your battery supports the grid
When California's grid is strained, Tesla calls an event and your Powerwall discharges stored energy. You're paid $2.00 per incremental kWh delivered — and your backup reserve stays protected. Tesla estimates $100–$450 per Powerwall per year.
PG&E
Tesla Virtual Power Plant. Events typically in the late-afternoon peak; $2.00 per incremental kWh delivered.
SCE
Tesla + SCE Emergency Load Reduction Program (ELRP). Same $2.00 per kWh, with events concentrated in summer 4–9 p.m.
- Enroll from the Tesla app in minutes — no cost to join.
- You set how much of the battery can participate, and can opt out of any event without penalty.
- Eligible with or without solar, with a valid interconnection agreement (Rule 21).
- Earnings are potential, not guaranteed, and vary by event participation.
Now put your own numbers in
Move the sliders to model your own time-of-use rate-shifting savings plus Tesla Virtual Power Plant earnings. Defaults use PG&E rates as an example — we'll run the numbers on your actual California utility and rate plan.
Based on PG&E's peak $0.5224/kWh vs off-peak $0.3994/kWh as a California example (a $0.123/kWh spread), 13.5 kWh usable per Powerwall and 89% round-trip efficiency. Tesla's PG&E Virtual Power Plant (one example program; other California utilities vary) pays $2.00 per incremental kWh delivered during events.

How the price works
Federal tax credit still available — through the lender
The $9,799 price is not a cash purchase. It is a prepaid PPA price that captures the remaining commercial clean-energy credit so you do not have to wait on a tax return or qualify for homeowner-level incentives.
Section 25D expired for homeowners
The federal residential clean energy credit (Section 25D) expired for battery storage on December 31, 2025. Homeowners can no longer claim the 30% tax credit directly on a battery-only purchase.
Section 48E still applies to companies
Commercial entities can still claim the Section 48E clean energy investment credit. SolarSesame partners with a financing provider that claims the credit and passes the savings to you as a lower upfront price.
Prepaid PPA = your discounted price
The $9,799 installed price is made possible through a prepaid power-purchase agreement structure. You pre-pay for the energy service, the lender claims the commercial credit, and you get the battery at a fraction of the cash cost.
Incentives change often
California utility rebates, Virtual Power Plant programs and federal tax rules can change with little notice. We keep this page current, but you should always verify the latest rules with the program source. Tesla maintains a public incentives guide for California homeowners.
- PG&E Permanent Battery Storage Rebate Program: up to $7,500 — homeowner applies directly.
- San Diego Community Power Solar Battery Savings Program: up to $350/kWh — homeowner applies directly.
- SMUD Battery Storage Rebate: currently the region's most generous battery rebate for Tesla Powerwall owners — but SMUD is reducing it soon, so apply early. See SMUD's program details — homeowner applies directly.
- Other city, utility or CCA rebates may also be available, but the homeowner is responsible for submitting those applications on their own.
Disclaimer: SolarSesame is not a tax advisor. The $9,799 price assumes the financing provider successfully monetizes the available commercial credit. Utility, city and state rebates are the homeowner's responsibility to apply for and are not guaranteed. Your final agreement, eligibility and pricing are subject to credit approval and program availability at the time of installation.

Free site review · No-pressure consultation
Transparent pricing — every possible add-on, listed up front
Most installers quote a headline price and hand you change orders once the work has started. We publish our full price list instead. Permit fees and, on most homes with existing solar, the Tesla Remote Energy Meter apply to nearly every project — so plan on those. Everything else depends on your home, and all of it appears on your SolarSesame install agreement before you sign, so it can be financed with the project instead of paid in cash at the end.
- City permit & utility interconnection application fees · applies to every project$800
- Site survey, if you'd rather not send us the 10 photos$500
- Tesla Remote Energy Meter, if required to connect to existing solar$500
- Battery located more than 15 ft from your main electrical panel · wiring runs $15 per ft beyond that$15/ft

Other uncommon site-specific or code-required upgrades may also apply — always quoted for your approval before any work starts.
Does it pay for itself?
Starting around $103 a month — and your savings can cover all of it
Most homeowners finance with a Figure HELOC instead of paying cash. At 6.35% APR over 30 years (excellent credit, primary residence), the Powerwall 3 + Expansion Pack starting price lands at about $103/month, while time-of-use savings and Tesla VPP earnings can run about $128/month. Adjust the numbers below to see your own break-even.
Choose your system
Prices shown are starting prices for standard installs. More complex projects — panel upgrades, long wiring runs, garage safety equipment or other code-required work — may cost more and are quoted after the site survey.
Savings default to the output of the calculator above (peak / off-peak bill savings plus Tesla VPP earnings). Payments match Figure's HELOC calculator: the system price plus Figure's 4.99% origination fee, financed over the term you pick. 6.35% APR reflects excellent credit (760+) on a primary residence — Figure sets your actual rate and approval, not SolarSesame.
Your monthly math
$0 out of pocket
Your savings cover the whole payment — and then some.
That means the Powerwall covers its own payment and leaves about $26 a month in your pocket — roughly $308 in the first year.
And what that buys you:
- •Whole-home backup instead of a generator — no fuel, no noise, no $5k–$15k install and no annual service contract.
- •Outages stop being an event — power switches over in a fraction of a second, so food, Wi-Fi, medical devices and A/C keep running.
- •A permanent home improvement — appraisers and buyers treat battery storage as an upgrade, and it stays with the house.
- •Rate protection — utility rates keep climbing, so the savings side of this math grows every year while your payment stays fixed.
Illustration only, not a financing offer. Payments assume a fully amortizing fixed-rate HELOC including Figure's 4.99% origination fee; Figure sets your actual rate, term, fee and approval. Home-value impact varies by market and is not guaranteed.
Ways to pay
Pay however works best for you
The price is the same no matter how you pay. Additional items such as permit fees, a site survey or a Remote Energy Meter appear on the same install agreement, so they can be financed with the project instead of paid in cash at the end.
Cash
Pay in full at the milestones listed on your SolarSesame install agreement. Simplest option, no interest, no lender.
Credit card
Card payments are accepted for your install agreement. Processing fees may apply and are shown before you pay.
HELOC (e.g. Figure)
Most homeowners use a home equity line. Rates are usually the lowest available and the payment can sit under your monthly savings.
GoGreen Home Energy Financing
California's state-supported GoGreen program offers lower-rate loans through participating lenders for qualifying energy upgrades.
Star One Credit Union
Solar loans at 6.25% interest, exclusively for solar and storage projects. You apply directly with Star One and we invoice them — see the details on Star One's solar loan page.
Your own financing
Bring a home improvement loan or any lender you prefer. We invoice you directly — no need to use ours.
Financing is provided by third-party lenders and is subject to their credit approval, rates and terms. SolarSesame is not a lender and does not set lender terms. GoGreen Home Energy Financing is a program of the California Alternative Energy and Advanced Transportation Financing Authority; eligibility is determined by the participating lender.
Two things we sort out before install day
First, where the battery can legally go on your home. Second, ten photos from your phone so we can design the system without charging you for a site visit.
Where your Powerwall can go — and why that can change the price
Tesla's installation manual and California fire and electrical codes set minimum clearances around an energy storage system. We walk every site against these rules before we quote, so you know exactly what your home needs.
3 ft from doors, windows and openings
Code requires the Powerwall to sit at least three feet away from any door, operable window or vent. This is the constraint that most often decides where your battery can go — and sometimes means a longer conduit run from the meter.
1 ft from the electric meter, 3 ft from gas
We keep a working clearance around your utility equipment so meters stay accessible for service and inspection. If the only compliant wall is far from the meter, extended wiring is quoted by the foot.
Garage installs: heat sensor + bollards
Indoor and garage installations add a listed heat sensor, impact protection bollards where a vehicle can reach the unit, and 3 ft of clearance to the door entering the living space.
The $9,799 starting price covers a standard installation. If the only code-compliant location adds wiring distance or requires garage protection, that's priced before work begins and approved by you first — see the full add-on pricing.
Clearances shown are typical requirements per Tesla's Powerwall 3 installation manual and California code. Your local authority having jurisdiction may impose additional requirements, which we confirm during permitting.
Send us 10 photos and we can design your system without a site visit
A physical site survey costs us about $500, and we charge that only when we have to send a surveyor out. Most homeowners can take these ten photos on a phone in about ten minutes and text or email them to their Energy Consultant instead — no fee, and your design starts the same day.
1. Meter-main panel — from ~15 ft
2. Meter-main panel — from ~5 ft
3. Electric meter face
4. Main panel breakers (dead front on)
5. Breaker schedule / circuit directory
6. Panel manufacturer's label
7. Main breaker
8. Gas meter — from ~10 ft

Questions homeowners ask
Everything our Energy Consultants get asked, grouped so you can jump to what matters to you.
The battery & your home
No. Powerwall 3 works as a standalone battery — it charges from the grid during cheaper off-peak hours and powers your home during expensive peak hours and outages. Tesla also allows battery-only homes into virtual power plant programs such as the one with PG&E, subject to eligibility requirements including a valid Rule 21 interconnection agreement.
Yes — this is a battery-only installation with no additional solar panels, and adding storage does not change or jeopardize your existing NEM 2 interconnection. Your solar stays on the same net-metering agreement; we file a storage addendum with your utility as part of the interconnection paperwork.
Most homes are served by the Tesla Backup Switch (meter collar), which is included. A Tesla Gateway is required instead when:
- Installing the Backup Switch would obstruct the electrical panel's access hatches, covers or doors — electrical equipment must remain accessible and operable per the NEC.
- The home's electrical service or main panel is rated above 200 amps, which exceeds the Backup Switch's supported service rating.
- The home has an existing generator connected through an automatic transfer switch. A Gateway is needed to properly coordinate and isolate the home's power sources.
- The existing solar system exceeds the allowable AC-coupled solar capacity for the proposed Powerwall system, so a Gateway-based design is needed to control and integrate it.
In these situations the Gateway provides the system control, isolation and equipment compatibility needed for a safe, code-compliant installation. It is listed on our price list at $1,800.
It depends on your home and what you want to back up. One Powerwall provides 13.5 kWh of storage and can typically keep essentials like your fridge, lights, Wi-Fi and outlets running for roughly a day.
If you want to run larger loads like AC, EV charging, pool equipment or more of your home, you may need 2 or more Powerwalls.
We'll review your electricity usage and backup goals to recommend the right number of batteries for your home.
Yes. Our listed prices are for a main Powerwall 3 plus Expansion Packs, which share the main unit's inverter. If you'd prefer a second full Powerwall 3 with its own inverter, add $1,500 to the quoted price.
A large annual true-up means you don't have enough solar production, not just a storage problem. A battery shifts when you use energy, but it can't offset panels you don't have. Tell your Energy Consultant — we can quote additional panels alongside the battery so both problems get solved.
Most installs are completed in a single day once permits are approved. Permitting and utility interconnection timelines vary by city and typically add a few weeks.
Price, fees & what's extra
The starting price covers a standard Powerwall 3 installation: the battery, the Tesla Backup Switch, mounting and electrical work, permitting paperwork, commissioning and walkthrough. Two items apply to almost every project and are quoted up front:
- City permit & utility interconnection application fees — $800
- Tesla Remote Energy Meter — $500, when the battery has to be connected to an existing solar system (most homes with solar)
Everything else is on our published price list in the pricing section above, and appears on your install agreement before you sign.
Some homes need extra electrical work, equipment or code-required upgrades — a main panel upgrade, a subpanel, longer wiring, garage safety equipment or a Remote Energy Meter. Every one of those has a published price in the pricing section above, and you can skip the $500 site survey by sending us 10 photos instead.
Other uncommon site-specific or code-required upgrades may also apply. No surprises: anything extra is identified before we start and quoted for your approval.
Because unknown fees at the end of a project are the worst part of home improvement. Quoting $800 up front means it goes on your install agreement, can be financed with the rest of the project, and you know your true total before you sign. It also means your battery is fully permitted and inspected — so it won't create problems years later when you sell or do another home project.
Using PG&E as an example, with peak at $0.5224/kWh and off-peak at $0.3994/kWh, every shifted kWh saves about 12.3 cents. A 13.5 kWh Powerwall cycled daily is roughly $606/yr in theory, or about $363/yr after 89% round-trip efficiency. We present a realistic range of about $350–$600 per year depending on your usage and how often the battery fully cycles. Other California utilities such as SCE and SDG&E have their own time-of-use spreads, so we quote savings against your actual rate plan.
During a qualifying grid event, your Powerwall discharges energy to the grid and Tesla pays $2.00 per incremental kWh delivered. Tesla's own example: a 13.5 kWh Powerwall with a 20% backup reserve has 10.8 kWh available, dispatches 7.8 kWh during the event, and earns $15.60 for that single event. Tesla estimates $100–$450 per Powerwall per year. Payments vary with the number of events and how much your battery contributes, and are not guaranteed. Source: Tesla's PG&E Virtual Power Plant program; availability and terms vary by California utility.
Agreements & the Prepaid PPA
Battery-only customers sign two documents:
- SolarSesame Install Agreement — the price you owe us, including any add-ons such as the $800 permit fee, a Remote Energy Meter or a site survey.
- HDM Prepaid Storage Agreement — the prepaid energy agreement that shows the value of the energy your battery delivers over time.
If you later add solar panels, there is a third document: a separate HDM solar-only agreement. Nothing else is hidden behind the scenes.
Prepaid PPA providers are in the business of claiming and monetizing the commercial clean-energy tax credit, which is what funds your discount. To qualify, the paperwork has to be a genuine power-purchase style agreement. HDM issues a Memorandum of Understanding stating plainly that ownership of the system transfers to you for $0 in year 6. SolarSesame has no power to change or modify the lender's agreement — if you'd rather not use the prepaid program, you can simply pay the full price of the battery instead.
You do. Your Powerwall is controlled through your own Tesla app — backup reserve, Self-Powered or Time-Based Control mode, storm watch, and charge/discharge settings are all yours to set at any time. The prepaid agreement is a financial arrangement; it does not hand over operational control of your battery.
No. This is not a lease. Your Powerwall is provided through a Prepaid Energy Storage Service Agreement. After 6 years, ownership transfers to you for $0, with no Fair Market Value payment required, subject to the terms of your agreement.
No. HDM is the prepaid vendor behind this program — and they have been in business for over 8 years without ever charging a single customer an additional Fair Market Value payment at the end of the term. They are the oldest and most reliable lender in the prepaid storage market, and the HDM Memorandum of Understanding states plainly that ownership of your Powerwall transfers to you for $0 in year 6.
You can read the MOU yourself in the documents section below — that's the whole point: you shouldn't have to take anyone's word for it.
Yes. Programs such as the PG&E battery storage rebate or San Diego Community Power's program are applied for by you directly as the homeowner, and those funds go to you. We'll point you to the right program; the application is yours to submit.
Warranty & service
Tesla provides a 10-year warranty on the Powerwall itself, and that coverage stays with your system including after ownership transfers to you. SolarSesame provides a lifetime workmanship warranty on anything caused by our installation work, and we're the ones you call — we coordinate with Tesla on your behalf rather than leaving you on a support line.
Your Powerwall is installed by licensed electricians in our certified installer network — every crew is trained to SolarSesame standards and held to the same install checklist. Because we stand behind every crew's work, our workmanship warranty can be lifetime.
Read the documents yourself
No need to ask a sales rep for paperwork — here are the prepaid program documents in full.
Documents are provided by HDM for review. SolarSesame cannot change or modify the lender's agreement. Prefer not to use the prepaid program? You can purchase the battery outright at full price instead.

Tesla Virtual Power Plant compensation of $2.00 per incremental kWh and estimated $100–$450 per Powerwall per year comes from Tesla and is not guaranteed. PG&E customers participate through Tesla's PG&E Virtual Power Plant and SCE customers through Tesla's SCE program (ELRP). SDG&E customers may be eligible through Tesla's SDG&E Virtual Power Plant. Eligibility requires a valid interconnection agreement and other Tesla and utility requirements. $19,999 is SolarSesame's standard list price for a standard Powerwall 3 installation. The $9,799 promotional starting price reflects a commercial tax credit passed through to the homeowner and is available for a limited time, while commercial tax credit funds last. $29,999 is SolarSesame's standard list price for 1 Powerwall 3 plus 1 Expansion Pack installed; $15,799 is the corresponding promotional starting price after the pass-through commercial tax credit. Final pricing depends on site conditions and may be higher for more complex projects. City permit and utility interconnection application fees of $800 are not included in the starting price and are quoted up front on your SolarSesame install agreement. Discounted pricing below $9,799 is available through our Prepaid PPA program; program availability, eligibility and final discounted pricing are confirmed during design and agreement.
