What’s the latest news on the Tesla Powerwall?
In early April 2021, Tesla stopped selling Powerwalls for individual sale. Instead, anyone who wanted a Tesla Powerwall would have to also install a brand new Tesla solar panel or solar roof system. That means no retrofits for existing solar systems, which is definitely a bummer.
Tesla then took it a step further later in April, when Tesla CEO Elon Musk tweeted that all Tesla solar panel and solar roof systems would be bundled with a Powerwall. So now, you have to purchase a Powerwall when you purchase solar panels through Tesla.
That wasn’t Musk’s only announcement. In Tesla’s Q1 2021 call, he revealed that Tesla has been manufacturing the “Powerwall +”, which has a higher peak power capability than previous models and comes with an integrated inverter, giving it a slightly different look than before. Overall though, the Tesla Powerwall+ has almost all the same features as the Powerwall.
All future Powerwall purchases will be the Powerwall+.
How much does the Tesla Powerwall cost in 2021?
As of July 2021, the total cost of installing one Tesla Powerwall+ battery system is $10,500.
The more Powerwalls you install, the cheaper they become. This is because the installation labor costs are spread out over the two batteries as opposed to just one.
And remember, Tesla no longer sells their Powerwalls individually, so the total amount you'll have to pay will be for the price of a Powerwall and the price of a new solar panel system.
The following table breaks down what goes into the cost of installing Powerwalls:
|Number of Powerwalls||Installation cost|
Despite Tesla claiming that the Tesla Powerwall cost would drop by half in the next three years, we’ve seen the price of the Powerwall increase twice, to its current price of $10,500, since that announcement in September 2020. Luckily, there are battery incentives available in some areas to help lower the cost of installation.
Not only can you take advantage of the 26% federal tax credit, some states and utilities offer additional rebates and incentives, as well. In some cases, rebates like California’s SGIP incentive and Green Mountain Power’s Bring Your Own Device Program in Vermont, can cover almost 90% of the total cost of installing a Powerwall.
You can order a Powerwall directly from Tesla’s website, or from a certified Tesla installer.
How long does it take to get a Tesla Powerwall?
Tesla Powerwalls have a substantial wait time because the demand for them is so high and their production simply can’t keep up. Some people have reported that they have to wait a full year before receiving the Powerwall they ordered.
It seems as though customers who order their Powerwall systems directly from Tesla have substantially shorter wait times - usually just a few months. However, those who have ordered Powerwalls through Tesla installation partners have waited almost a year to get their Powerwall. It seems Tesla has prioritized filling their direct orders first, and are leaving their installation partners out to dry.
There has been a spike in Powerwall demand, mostly related to the increase in widespread power outages, like the ones that have recently occurred in California and Texas.
So, if you’re looking for a battery to add to your already existing solar system, or you don’t want to wait a year or more to get a solar battery installed, you’ll need to find a Powerwall alternative.
Key features of the Tesla Powerwall
What exactly do you get when you pay for a Tesla Powerwall? The answer is: a lot.
The Tesla Powerwall has some of the best technical specifications in the solar battery game, as well as impressive smart monitoring and management.
|Feature||Tesla Powerwall+ specification|
|Total energy capacity||14 kWh|
|Usable energy capacity||13.5 kWh|
|Continuous power rating||On grid: 7.6 kW full sun/5.8 kW no sun, Off-grid: 9.6 kW full sun/7 kW no sun|
|Peak power rating||Off-grid: 22 kW full sun/10 kW no sun|
|Round trip efficiency||90%|
|Depth of discharge||100%|
|Dimensions||62.8 in x 29.7 in x 6.3 in|
|Operating modes||Solar Self-Consumption, Time-Based Control, Backup Power|
With the ability to hold 13.5 kilowatt-hours (kWh) of electricity, the Powerwall can store enough energy to cover about half of the average U.S. home’s daily energy usage.
The Tesla Powerwall+ comes integrated with the Tesla inverter and system controller, which allows for a quicker and more condensed installation.
Aside from the new installation setup, the main difference between the Powerwall and the new Powerwall+ is the power output, which now is slightly higher than industry standards. In full sun conditions, the Powerwall+ can now provide 7.6 kW of continuous power and 5.8 kW with no sun when connected to the grid. This means the battery can power things such as lights, electrical outlets, and small 120-volt appliances.
For off-grid applications, however, the Powerwall+ can release more power - between 7 kW and 9.6 kW - depending on the conditions. So, when your Powerwall is not connected to the grid, like during a power outage, it has the ability to power a few more appliances in your home.
The upgraded Powerwall also has a much higher peak power capacity when operating off-grid, ranging from 10 kW to a whopping 22 kW if the sun is shining. The peak power capacity is the absolute maximum amount of power a battery can supply for a very short period of time. Usually, the battery will reach peak power capacity when multiple appliances are being turned on at once, like when the power goes out and comes back on.
The Powerwall+ also has three standard operating modes:
- Solar Self-Consumption
- Time-Based Control
- Backup Power
These modes allow you to choose how and when you release and store energy in your battery. For instance, in Solar Self-Consumption Mode, you can power your home with renewable energy by storing solar power for use later, or the Powerall can just serve as an emergency battery backup in case of a blackout.
The Powerwall’s warranty is pretty standard for lithium ion batteries - the battery will operate at 70% of its original capacity after 10 years. Which operating mode you choose will impact how long your Powerwall battery will last. The specifics of how your usage impacts the battery life are outlined in Tesla’s warranty.
How many solar panels do you need to eliminate your electric bill?
How do other solar batteries compare to the Powerwall?
There are many solar batteries on the market to choose from. Some of Tesla’s top competitors include the LG Chem RESU Prime and the new sonnenCore battery.
How exactly do these batteries stack up to the Powerwall? Let’s take a closer look.
|Feature||Powerwall+||LG Chem RESU Prime 16H||sonnenCore|
|Battery chemistry||Lithium nickel manganese cobalt (NMC)||NMC||Lithium iron phosphate (LFP)|
|Usable energy capacity||13.5 kWh||16 kWh||10 kWh|
|Power rating||On grid: 7.6 kW full sun/5.8 kW no sun, Off-grid: 9.6 kW full sun/7 kW no sun||7.0 kW continuous / 11.0 kW peak||4.8 kW continuous / 8.6 kW peak|
|Operating modes||Solar Self-Consumption, Time of Use, Backup Power||Solar Self-Consumption, Time of Use, Backup Power||Solar Self-Consumption, Time of Use, Backup Power|
|Warranty||10 years or 37.8 MWh throughput||10 years or 54 MWh throughput||10 years or 58 MWh throughput|
All three batteries have the same basic operating modes:
- Solar Self-Consumption Mode - Your solar system will send the extra energy it produces during the day to the battery that can then be used later to power your home when your solar panels are no longer producing energy
- Backup Power Mode - The battery will be charged by solar or from the grid to power your home in the event of a power outage
- Time of Use Mode - The battery will change how its charged based on the price your utility is charging for electricity with Time-of-Use rates
Though all three batteries have the same operating modes, we had to do some digging to figure out what modes the LG Chem Prime actually offered. It’s not listed anywhere explicitly on their site or in their operating manuals.
Capacity and power rating
In terms of power ratings, the Powerwall+ can deliver more power than the LG Chem and the sonnenCore. But, the LG Chem Prime can store more energy, so it can power your appliances for longer.
While the Powerwall+’s peak power capabilities pack quite the punch when operating off the grid, there’s nothing on the spec sheet to tell us what the peak power capacity is while it is connected to the grid. We can assume that it’s higher than 7.6 kW, which is the maximum amount of continuous power that the battery can deliver, but we don’t know if it’s high enough to beat the LG Prime’s peak power capacity of 11 kW.
Although the Powerwall has an impressive power output, the LG Chem Prime comes out on top for this one. The Prime still offers a higher-than-average power output, plus it can hold more energy.
All of these batteries are able to operate at 70% of their capacity after 10 years with regular use. But when you look at the fine print, you’ll find that the sonnenCore and the Tesla Powerwall have a better warranty than the LG Chem Prime.
The sonnenCore will operate at 70% of its original capacity after it releases 58 megawatt-hours (MWh) of electricity, or after 10 years - whichever comes first. In order to use 58 megawatt-hours of electricity from the sonnenCore before you reach ten years, you’d have to completely discharge the battery more than once a day, which is extremely unlikely.
The Powerwall will also operate at 70% of its capacity after 10 years with unlimited cycles. This means no matter how many times you discharge the battery, its capacity won’t drop below 70% until Year 10.
The LG Chem Prime, however, will operate at 70% of its original capacity at 10 years or after it has released 54 megawatt-hours of electricity, whichever comes first. This means you would reach 54 megawatt-hours if you discharged the battery every day for a little over 9 years, so you could end up reaching the throughput limit first, and having your battery operate at a lower capacity sooner.
However, the LG Chem Prime itself has a high capacity to begin with, so it would still be operating at 11.2 kWh of capacity, which is larger than what you start with, with the sonnenCore.
Overall, the Powerwall has the best performance warranty, but the LG Chem Prime would actually last longer because it has a higher starting capacity.
The LG Chem Prime definitely offers the best value for the price. In order to compare the prices better, we need to look at how much each battery costs per kWh of electricity they can store.
The LG Chem Prime costs around $9,000 before installation costs, which comes out to about $562 per kWh of storage. Compare that to the Tesla Powerwall, which is about $629 per kWh. The sonnenCore is much more expensive, as it costs around $950 per kWh.
In terms of what’s going to give you the most bang for your buck - it’s the LG Chem Prime.
Is the Tesla Powerwall worth it?
In our opinion, the Powerwall is a great battery. It has advanced features and impressive technical specs for a decent price.
But is the Powerwall worth it? To be honest, not really. The battery that we put at the top of our list is the LG Chem Prime because of its high power capacity, operating modes, and low price.
Unfortunately, Tesla’s decision to only sell Powerwalls with new solar panel installations makes it much harder for homeowners to get their hands on one, which is a huge letdown for a few reasons.
First, homeowners who already have solar panels and want to install a battery can no longer get a Powerwall.
Second, when it comes to solar installations, Tesla is notorious for having poor after-sales service. So now, if homeowners want a Tesla Powerwall, they run the risk of dealing with the subpar customer service that Tesla has been known for. And that’s not just when you’re getting the system installed, it’s a problem you’ll have to deal with over the lifetime of the solar panels - a whole 25 years!
Plus, Tesla recently increased the prices of solar roof systems for customers who already signed contracts, making it even more difficult for consumers to trust them. Who’s to say they won’t increase your prices after you sign a contract?
Tesla Powerwall Manual
You can still get a Powerwall installed through companies like Sunrun, but even then you can’t pair a Powerwall with an existing solar installation. Besides, with Tesla filling their own orders before honoring projects their installation partners have already signed contracts for, there’s no telling when you’ll get a Powerwall from someone other than Tesla.
So if you already have solar installed on your roof, we’re sorry to say it seems like you’re out of luck.
With all that being said, if you don’t already have solar, are willing to risk getting poor customer service over the 25 years that you have Tesla panels on your roof, plus are okay with potentially month or year-long wait times to get a battery installed, then a Tesla Powerwall is right for you.
If that’s not going to cut it, you can always contact local solar installers and find out what solar batteries they recommend, or if they have Powerwalls in stock to install.
