Battery Chemistry

The Tesla Powerwall and the Powerwall+ are lithium-ion batteries; specifically, they are lithium nickel manganese cobalt oxide (NMC) batteries. These batteries are quite popular and have become one of the most common types of home storage options.

NMC batteries are known to have a longer lifespan and better performance than other batteries on the market. They have a higher power density, which means they can store a significant amount of your home energy but take up less space. Both batteries can withstand the elements and have operating temperatures between -4°F to 122°F.

Battery Capacity

The Powerwall and the Powerwall+ can store 13.5 kilowatt-hours (kWh) of power for your home. This capacity is higher than the typical battery, making it easier for homeowners to store more of their excess energy. Even when sunlight is low, the batteries will continue to draw power from the grid for later consumption.

You can expand your battery capacity by adding extra batteries to your solar power system. A typical home needs at least two Powerwall batteries to provide adequate power to go off-grid. This added protection will ensure you maintain energy independence even when your solar panels are not in use. Tesla states that a Powerwall power system can consist of up to 10 Powerwall batteries.

Solar Inverter

The Powerwall has incredible flexibility to integrate into an existing solar system. According to Tesla , the battery is compatible with several solar inverter brands, including Enphase, SolarEdge and SMA. Its inverter helps convert the stored direct current (DC) energy into the alternate current (AC) power that your home needs to run. The Powerwall+, on the other hand, comes with an integrated Tesla solar inverter, making it an excellent all-in-one home battery option for a brand new system.

Tesla Powerwall Performance

We found that the Tesla Powerwall’s features met or exceeded several standards for a typical solar battery. Along with its baseline storage capacity, we examined the battery’s functionality, efficiency and ease of use. Below are the highlights of the Tesla Powerwall’s overall performance.

Power Output

The Powerwall has a power output of 5.8 kW of continuous power and 10 kW of peak power. These numbers also reflect the Powerwall+’s performance capabilities when no sunlight is present. On a completely sunny day, the Powerwall+ gets an added boost, increasing production to 7.6 kW of continuous power and 22 kW of peak power.

Depth of Discharge

The Depth of discharge (DoD) measures how much energy can be pulled from a battery before its lifespan is affected. Since drawing 100% of a battery’s power would reduce its lifespan more quickly, many manufacturers keep a lower limit to preserve the battery. However, Tesla’s batteries can withstand complete power drainage without affecting their lifespan. Both Powerwall batteries rate at 100% for the DoD.

Round-Trip Efficiency

Round-trip efficiency measures the percentage of electricity put into storage that can be retrieved in order to power your system. The higher the round-trip efficiency, the less energy is lost in the storage process . Both Tesla Powerwall batteries have a 90% round-trip efficiency, higher than the industry standard of about 60% to 70%. This means you will have at least 90% of the stored energy available for your usage.

Operating Modes

The Powerwall system uses three operating modes to control its batteries.

• Self-Consumption : This allows the system to store energy directly in the solar battery.
• Time-Based Control Mode: This selection works best if your utility company uses Time-of-Use (TOU) rates, when your rate fluctuates based on the time of day you’re using energy and the demand for electricity. In this mode, Tesla’s battery will automatically begin storing energy when electricity rates are at their lowest. You can then draw from the battery once rates have increased, such as on a hot summer afternoon, helping you to save on your electricity bill.
• Backup Only: Homeowners can select this mode if they only want to use the Powerwall as an emergency backup. The battery will switch to battery backup power mode when it detects no active power being drawn from the solar system, such as during a blackout.

Customers can toggle between the modes on the Tesla mobile app. The Tesla app provides details on your energy consumption, storage capacity and panel productivity in real time. Both Powerwall batteries have Wi-Fi capabilities and sync with the app via the Powerwall Gateway 2. This electronic panel communicates directly with the battery and performs regular system checks automatically. The gateway can be mounted indoors or outdoors and can control up to 10 batteries.

The Powerwall Warranty

A solar battery warranty often includes more than the standard workmanship coverage. These warranties typically cover efficiency, labor and performance. Here’s a detailed breakdown of the Tesla Powerwall warranty and why it stands out compared to other battery warranties.

Warranty Length

Tesla Powerwall batteries are covered by a 10-year warranty, the industry standard for coverage. However, Tesla also provides a four-year workmanship warranty covering the labor for repairs and replacements. In addition, the shipping for any parts is included, a benefit that is often missing in other warranty plans.

End of Warranty Capacity

Over time, solar batteries gradually lose their energy capacity. Standard solar battery warranties have a clause guaranteeing a minimum of 60% capacity by the end of the warranty. The Tesla Powerwall has a higher end-of-warranty capacity of 70%. Given that the standard lifespan of a solar battery is as long as 15 years, an investment in the longer-lasting Tesla Powerwall battery can pay off down the road.

Throughput and Cycle Expectancy

Though we’ve highlighted some of the clauses that Tesla includes in its warranties, it’s important to highlight a few that have been omitted for the customer’s benefit. Solar battery manufacturers typically add performance stipulations that can potentially end a warranty before its coverage time frame. For example, the inclusion of a throughput or cycle expectancy clause can be troublesome since the battery could reach these thresholds early on. The throughput is the amount of energy that the battery is expected to deliver during its lifetime. This measurement, listed in megawatt-hours (MWh), could be so low that you reach it before the end of your warranty. Similarly, the cycle expectancy measures the number of times your system completely charges and discharges. Manufacturers could include a clause with a low threshold of 4,000 cycles or as high as 10,000. When added to a warranty, these stipulations serve as secondary conditions for the warranty end date. For example, your warranty could last for 10 years or end earlier, when you reach the cycle expectancy or the throughput estimate. However, Tesla has intentionally excluded these clauses. Instead, the Powerwall has an unlimited cycle clause, essentially guaranteeing your coverage will last for 10 years.

Tesla Powerwall Cost and Installation

Tesla Energy is very clear about the prices of its products. The website will recommend the number of Powerwall batteries needed for your home based on your average monthly electricity bill. The price for one Tesla Powerwall is $11,500. If you decide to purchase two storage systems, the cost increases to $18,500, or $9,250 per battery. Homeowners can purchase the Tesla Powerwall directly from the company’s website. The purchase will need to be included with an order of Tesla solar panels or solar shingles. Customers can also use their battery with the Tesla electric vehicle (EV) charger. Certified third-party Tesla solar installers complete all Tesla installations. If you want to add the Powerwall to a non-Tesla solar system, you’ll need to purchase one through a third-party retailer. Some solar panel providers carry the Tesla Powerwall as an add-on option and can include it in your system during the design process. If you already have a solar system and just want to add a battery, you will need to find a certified Tesla installer in your area to complete your upgrade. To help offset the costs of a new solar system, homeowners should take advantage of any state tax credits, incentives or rebates. Local utility companies and city governments may offer additional rebates and credits. You can also qualify for the federal solar tax credit , which provides a federal tax reduction equal to 30% of the total cost of a new solar system. Solar batteries are included but must be purchased with a complete solar system. Beginning in 2023, stand-alone solar batteries will qualify for the credit as well.

The Bottom Line: Is Tesla Powerwall Right for You?

The Tesla solar Powerwall is rated as one of the best solar batteries for homeowners. Though the price point is higher than the average solar battery, the larger capacity will be enough to meet your energy needs. In addition, advanced, self-powered operating modes give you more control over how you use your solar battery system. Whether it’s for unexpected power outages or to help lower your electricity bill, the Powerwall and the Powerwall+ will be a beneficial addition to a residential solar panel system. When deciding if the Powerwall is the right choice for your solar system, we recommend comparing the battery with at least two other storage options. You should compare the storage capacity, functionality, efficiency and warranty coverage.

Tesla Powerwall: Market Price and kWh Capacity

Just two decades ago, when climate change became apparent and solar panels made their debut on the retail scene, the need for electricity stored in a cheap and efficient way became apparent as well. As solar panels started appearing on more roofs, solar energy became a prominent contributor to the energy sector. Rechargeable lithium-ion battery technology became cheaper, and the way was paved for large-scale storage capacity.

What Is Tesla Powerwall?

Tesla Powerwall is the result of the changes in the use of electricity. Solar panels became cheaper thanks to mass production, and the same thing happened with solutions for stored energy. The opening of the Tesla Giga Nevada in 2016 represented a huge milestone in the field, as it provided a means for stored energy that was standardized, scalable, and affordable. Solar batteries, such as Tesla Powerwall, Tesla Powerwall 2, and Tesla Powerwall+, became a reality.

Tesla Powerwall Price

Tesla Powerwall price has been changing since the Tesla Powerwall 1 was introduced. At first, it cost $3,000 for 6.4 kWh. Later on, Tesla Powerwall 2 was introduced. It came with two price tags; $6,500 and later on, $7,500 for 13.5 kWh of storage capacity. The latest model, Tesla Powerwall+, comes with 13.5 kWh of storage capacity and at an initial price tag of $8,500.

Currently, the price for the same model is $10,500, and it comes only with a Tesla solar panel system. Purchasing the Tesla Powerwall as a separate device is still possible, but only through a certified Tesla Powerwall installer. Even then, you may have to wait up to a year to get your device since Tesla has a backlog of almost 80,000 batteries yet to be made.

Tesla Powerwall Settings

Your Tesla Powerwall has settings or modes that enable you to utilize the stored energy in the best possible way. To use all the benefits of a Tesla Powerwall, you should combine it with solar panels or a Tesla solar roof. Tesla solar panels seem to work the best with Tesla solar batteries, as the devices are fine-tuned to work in tandem. Here are the Tesla Powerwall settings:

Solar Self-Consumption

Solar self-consumption mode enables you to use your solar panel system even at night and in regions where there is no net metering. During the day, your solar panels produce electricity that your appliances use. Any excess energy is stored in your Tesla battery to be used at night.

Backup Power

Your Tesla battery can be used for backup only. In this case, the battery will charge and wait until there are power outages to start using stored energy. It can charge either from the grid or your solar system.

Time-Based Control

Time-based control allows you to reap the benefits of having electricity rates that change throughout the day. Speak with your energy provider and see when the electricity is the cheapest. Your Tesla Powerwall will charge during this time and release the energy during times of high energy prices.

Storm Watch

The storm watch function will monitor the data from the weather service station and charge up before a major storm hits your area. In the case that there is a power outage, your Tesla battery will detach itself from the grid and power your house until there is no more juice in it.

Preconditioning

A rechargeable lithium-ion battery cannot be charged to 100% in cold weather. To prevent this from happening and enable you to always use 100% of your storage capacity, Tesla energy has made sure that the battery can heat itself to operating temperature to store more energy during the coldest periods of the year.

Benefits of Buying Tesla Powerwall

There are many benefits of buying a Tesla Powerwall. With this device, you will be able to use more renewable energy and, depending on how many solar panels and solar battery devices you have, go completely off-grid. The Tesla Powerwall+ also has a built-in solar inverter so that you can think of one less device.

Self-Powered Home

Nothing says off-grid as a pack of 13.5 kWh of stored energy in your garage or basement. Lithium-ion batteries allow you to have a self-powered home even in remote areas and provide power even during blackouts. Depending on the energy use and usable electricity of your Tesla Powerwall 2 or + version, you will be able to pay $0 for your electricity for at least ten years.

Home Energy Control

Your Tesla Powerwall 2 comes with a handy Tesla app that lets you monitor and control your energy needs and energy storage levels in real-time. The app is intuitive and easy to use and shows how much energy your solar panels produce and home consume. This can help you bring future informed decisions on your new appliances or a solar system.

Backup Power

Having a source of backup power can help you in times of need. Your battery can serve as an emergency energy source and can even communicate with your local weather service and anticipate upcoming storms. In this case, the battery charges itself up and provides electricity in the case of an outage.

Energy Savings

If you have a variable-rate energy plan or your energy provider allows for a time-of-use plan, you can reap the benefits of low rates all day long. When the rates are low, your Tesla Powerwall 2 charges itself. When the rates are high, the Powerwall releases the energy so that you can enjoy low tariffs even during peak time.

AC-Coupled

Unlike Tesla Powerwall 2, Tesla Powerwall+ is AC-coupled. This means that the device already has an integrated solar inverter. This reduces the price of your entire solar system, which makes it really easy to connect your battery storage to your existing solar installations.

How Does Tesla Powerwall Work?

Both Tesla Powerwall 2 and Tesla Powerwall+ give you the ability to store power. Based on how much electricity you use, you may even go for 2-3 Powerwalls to meet your energy needs. The system that controls the Powerwall batteries learns about your energy use and pricing and adapts itself to offer the most benefits.

With Solar

Your Tesla Powerwall 2 works in tandem with solar to ensure you use most of the renewable energy you produce. During the day, your solar panels produce solar power to run your appliances. Any excess electricity is sent to Tesla batteries for energy storage and later use. This system effectively allows you to go off-grid, especially with additional powerwall units.

Without Solar

Your Tesla Powerwall 2 can also work without solar. In this case, your battery storage starts to store electricity from your utility grid when the prices are the lowest. The energy storage releases that same power when electricity prices are at their lowest. This allows you to save money by offering you reduced prices during peak demand times.

Key Features Tesla Powerwall

When considering any battery or a solar battery to extend your solar panel array, it is a good rule of thumb to compare their key specs. The most important features of any battery are listed below. Together, they can influence the price and the performance of your power storage system.

Battery Capacity

Your Tesla Powerwall 2 battery has a capacity of 13.5 kWh. Older models, such as the Tesla Powerwall (1), had a capacity of 6.4 kWh. The newer model can run an average American household for 12 hours, which is more than enough, especially when coupled with solar power.

Battery Type

Tesla Powerwall contains 21-70 types of batteries. Their production began on January 1st in 2017. The benefits of these batteries are that they are around 20% more energy-dense and around 9% cheaper than the previous 18-65 model.

Power Rating

Power Rating is another very important spec that you should pay attention to before purchasing a power storage unit. Power rating tells you about how many appliances you can run and for how long. It also tells you about the maximum power output of a battery, even if for a short time.

Continuous Power Rating

The continuous power rating of your Tesla Powerwall tells you how many appliances you can run all at the same time. The power rating depends on your Powerwall system and how many batteries are connected to the home. Continuous power rating is important during the normal day-to-day use of appliances.

With a Powerwall 2 maximum power rating of 7.6 kWh when the sun is shining, it can run your oven, hotplate, TV, fridge, freezer, and lights simultaneously. It can run even more appliances during outages as it can release a maximum power rating of 9.6 kWh during a blackout. A higher power rating means that you can use more appliances at the same time.

Peak Power Rating

Your peak power rating is the maximum power rating that your Powerwall 2 can release in a short period of time, usually a couple of seconds. This peak rating is needed when the devices you use start themselves or during peak operating times. Tesla Powerwall 2 has a peak of 10 kWh with no sun and 22 kWh during sunshine.

Depth of Discharge (DoD)

Depth of discharge is another important factor to consider when choosing your home or solar battery storage. This percentage shows how much of the energy capacity of your Tesla’s Powerwall you can actually use. The higher the percentage, the more electricity you can use from your home battery. The maximum amount of the Powerwall 2 you can draw is 100%, meaning you can discharge 13.5 kWh from it.

Round Trip Efficiency

During the charging time, some electricity is lost. The same happens when the battery is discharged. The total energy in the cycle minus the energy losses in both steps gives you the round-trip efficiency. Your Tesla battery storage has a round trip efficiency of 90%.

Warranty

All Tesla Powerwall devices come with a ten-year warranty. The warranty says that the device will retain 70% of its usable capacity at the end of the 10-year period. This is better than some other devices that store electricity, but Tesla’s customer support is known to be very laggy and unprofessional for existing customers.

Best Place to Buy Tesla Powerwall

The best place to buy your Tesla Powerwall is on the Tesla website. This way, you can get your battery storage in as little as a few months and connect it to your utility grid. The most significant benefit of buying directly from the manufacturer is that Tesla will install your Tesla battery. Installation costs are included in the prices on their website.

The next best place to buy a Tesla Powerwall is a certified Tesla Powerwall installer and seller. You can find information on Tesla Powerwall certified installers and sellers on Electricrate. This way, you will wait longer (up to a year) but will know that a certified body is doing the purchase, delivery, and installation. There is no difference in the performance of the battery itself.

Incentives or Rebates: Does Tesla Powerwall Qualify?

Your Tesla Powerwall qualifies for solar rebates only if it is coupled with a solar panel system. Considering that Tesla sells their Powerpacks in combination with a solar panel system, an average home can get the incentives or rebates for the Powerwall as well. On the other hand, if you purchase your Tesla Powerwall through a Tesla Certified installer, you may not be eligible for rebates and incentives.

Federal Tax Credit – ITC

If you install your battery storage at the same time as your solar panel system, you will be eligible for the 26% Federal Tax Credit. Under this incentive, you can deduct 26% of your Tesla Powerwall off your owed Federal Taxes. Any unused tax credit can be rolled over for up to 10 years.

California SGIP

Your Tesla Powerwall can also be eligible for California SGIP Self Generation Incentive Program. Under this program, your Powerwall can receive a significant rebate. However, since the program operates on a first-come, first-serve basis, there is no guarantee that your investment will receive a rebate. If you want to apply, you have to connect your Powerwall to a solar system and cycle the battery. You cannot use it as a backup power source.

FAQs

Can Tesla Powerwall be installed outside?

Yes, in some climates, you can install your Tesla Powerwall outside. However, if the temperature drops below -4℉ during winter or rises above 122℉ during summer, you may consider another place. The attic, the basement, and the garage are all great places to install a Powerwall.

How much will a Tesla Powerwall save me?

Depending on where you live, your Tesla Powerwall can save you up to $0.11 per kWh if you use it to store energy from the grid during low-demand hours and use it during peak hours. This way, you can save around $1.50 per day or $45 per month. Please check with your local Tesla-certified installer before purchasing.

Can the Tesla Powerwall be stacked?

Yes, you can stack your Tesla Powerwall. An average home storage capacity system has 2-3 powerwalls stacked. This way, you get 40.5 kWh of energy stored for emergencies and periods with no sunshine. Considering that an average USA home consumes around 30 kWh of power a day, this is just enough even for busy evenings with friends by the hot tub.

How long does it take to get a Tesla Powerwall?

Depending on who you order your Tesla Powerwall from, you can expect to wait up to a year to get your Tesla storage. If you order through a Tesla-certified installer, you can wait up to a year. If you place your order on the Tesla website, the wait times are shorter, but it will still be a few months before your Powerwall is installed.

Conclusion

Tesla Powerwall is the next best thing after solar panels. This amazing electricity storage solution allows you to use electricity stored during a power outage or during periods when there is no sun. Stacking 2-3 powerwalls will easily allow you to store enough energy for a full day. Combining a Tesla Powerwall with a solar roof or solar panels will help you use the solar energy you produce fully and save you more money than a powerwall on its own.

Tesla’s Powerwall 2 and Solar Roof Tiles: Our Review

In October 2016, Tesla announced the Powerwall 2 home storage battery, significantly updating the first generation’s capabilities. The new version has twice the energy density (14kWh vs last year’s 7kWh) and comes with an integrated inverter, which the previous version did not include. This means the home backup market just got more competitive, a good thing for consumers. Home battery solutions can provide emergency power during an outage or store electricity for hours when prices are higher or the sun isn’t shining. If several batteries are combined with solar panels, a battery bank can even power an entire house for off-the-grid living.

Each Powerwall 2 costs $5,550, and the average US home will need 2 or 3 to supply its power needs. A single Powerwall can provide limited backup power for critical appliances and lights, but not enough for the entire power usage of a typical house.

A potential downside to the Powerwall 2 is that it uses a different battery chemistry, nickel manganese cobalt (NMC), which is more volatile than traditional lead-acid batteries or another common lithium-ion chemistry, lithium ferrous phosphate (LFP). Under ideal conditions, NMC batteries are safe, but when punctured or improperly charged, there is a small risk of fire. Most

recently this happened with the Samsung Galaxy Note series of phones, but there have been other isolated incidents in the past. Additionally, temperature could play a role: NMC is more sensitive to charging at low or high temperatures and have strict temperature operating ranges. There have not been any reports of Powerwall dangers so far. While not something to panic about, it is one point to be considered when choosing a battery pack meant to last a decade. Lead-acid batteries are cheaper and field-tested over decades. LFP lithium-ion batteries offer longer lifespan, higher current capacity, and inherently safer chemistry. Either could be alternatives to NMC.

On paper the Powerwall 2 is a good deal, but based on specifications from Tesla and its battery partner, Panasonic, it remains to be seen whether the unit can truly live up to the hype. The technology seems better suited for electric vehicles, not ideally home energy storage (because this particular chemistry prioritizes smaller physical size over safety or longevity). We have systems immediately available with more storage capacity, more output, and more cycles for a competitive price. We are continually looking at new battery technologies and are very interested in some of the advancing lithium ferrous-phosphate products soon to enter the marketplace as Powerwall competitors, but right now, we still recommend traditional lead-acid as the best combination of price, performance and safety. Even if you are dead-set on going with the more modern lithium-ion batteries, we’d recommend at least waiting until early 2017 for competing batteries from Sony, Mercedes-Benz, etc. to come out. Some of them will use the safer LFP chemistry, and the additional time will give the market and early adopters a chance to figure out any potential kinks.

You can learn more about the Powerpack 2 from Tesla’s website or give us a call at 1-800-472-1142 for alternatives. Unlike Powerwall’s one-size-fits-all approach, our battery backup systems come in different sizes tailored for any home, and we’ll help you figure out the right system for your specific requirements — with or without solar panels.

Solar Roof Tiles

Tesla also announced their new solar roof tiles — on the set of Desperate Housewives in Universal Studios, no less, perhaps a nod to the increasing mainstreaming of household solar.

Tesla’s new tiles are stunningly beautiful, but they are not the first building-integrated PV system. Other companies have tried to market similar products in the past, but are usually held back by reliability, maintenance, and cost concerns. Hopefully, Tesla has been able to address the reliability concerns but price and availability are still unknowns. Consumer Reports estimates that Tesla solar roof tiles could cost up to $70,000. If true, it would likely be over a decade before this technology is cost-effective compared to conventional panels, during which time a conventional system would’ve already paid for itself.

Like Tesla’s first electric cars, these new tiles are aimed at a luxury market (or perhaps locations where homeowners’ associations make traditional panels difficult). We won’t know its true cost-effectiveness until Tesla releases more details about longevity, maintenance, and pricing. Our guess is that they will be out of the price range of many homeowners, at least at first.
