Tesla Powerwall Cost | Tesla Home Battery Price

What is the Tesla Powerwall home battery?

The Tesla Powerwall home solar battery storage is an integrated battery that stores solar energy. It can be used in two ways: to charge the batteries or as a power source for your home.

The cost of the Tesla Powerwall will vary depending on how you use it, but it’s within reach for most homeowners. Furthermore, the Tesla Powerwall home battery is a solar battery designed to work with an array of solar panels. It stores energy from both rooftops and the grid so that it’s available when needed. This product can be used in homes or businesses as it has significant benefits over other traditional batteries such as lithium-ion cells

It will also help utilities by reducing peak demand on power grids since they are becoming more decentralized due to renewable energy sources such as wind and solar


Tesla’s Powerwall is about 44 inches tall and 29.5 inches wide (112 cm x 74cm). It weighs nearly 200 pounds (90 kg) and has a life expectancy of more than 10 years, with about 90% of its capacity available after daily cycling for 10 years. It uses industry-standard lithium-ion batteries like those used in electric cars and can be mounted on the wall or the floor.

Basic functionality

The Tesla Powerwall is a home battery that offers software solutions for rate arbitrage. The basic functionality of the device is compatible with most types of off-grid inverters. It provides a backup solution for homes and small businesses that is independent of the grid. Inverter power rating will have to be matched to Tesla’s Powerwall power rating.

While you can use it when sunlight isn’t available, that’s not the primary function of the Powerwall. It’s designed to be used in conjunction with solar panels so that they can store energy when it’s generated and release it during high-demand times such as when everyone gets home from work or on hot summer days.


The Powerwall is available in two models: a 10 kWh version and a 7 kWh version. The more expensive model can generate 2,000 watts of power for up to four hours and the less expensive one can generate 1,000 watts for up to six hours. Because both products cycle daily, your usage will vary depending on the season.

A single battery needs 220 V AC or two separate 110 V AC lines to work. At full capacity, this accounts for about 1 kW of electricity. It has an integrated inverter that converts direct current (DC) stored in the batteries into alternating current (AC). The inverter’s small size means it could be installed near where it’s needed rather than at the source of power generation, likely a solar panel array or the grid.

To help you determine which Powerwall is right for your home, Tesla has a handy power calculator on its website. When you plug in the average amount of power required by a household and select a battery size, it will give you a monthly cost estimate for installation and maintenance.

The larger model is sized more to store up energy from utilities or solar panels when prices are low and release it when they’re high. The smaller model is designed for backup applications such as powering your home during a blackout.

  • 10 kW (7 kW on Powerwall 2 units)
  • Size: 45.3 in x 29.6 in x 5.75 in
  • Weight: 251.3 pounds
  • -4°F to 122°F Operating temperature range
  • 10 years warranty

With the Tesla Powerwall, homeowners with solar panels can store excess energy generated during the day for use at night.

Powerwalls have an integrated inverter, so installation requires less equipment and makes it easier to switch to a new provider if necessary.

How much does the Tesla Powerwall cost?

tesla powerwall cost

The Tesla Powerwall costs between $12,000 and $16,500 for a complete system installation (before incentives and taxes). The price includes all parts needed to make the battery functional. Additional labor may be required; check with your local contractor for details.

Tesla Powerwall price depends on the size you choose. The smallest power pack has a capacity of 7 kWh, suitable for those who own smaller solar installations or those who live in areas with stable electricity rates.

If your power needs are more substantial, you can opt for a battery that stores twice as much energy: a 14 kWh power pack costs about $8,000 more than an equivalent 7 kWh unit. If you require a huge reserve of electricity, you can purchase Tesla’s largest power pack with a capacity of 52 kWh for around $13,500 more than the cost of two 7 kWh batteries.

When seeking out an installer to buy and install your Tesla Powerwall battery, make sure they are experienced in-home energy storage systems. If you lack experience in these matters or have been putting off renovating your home due to the daunting task ahead, consider hiring a contractor familiar with installing PV solar panels as well. The installation process is fairly complex and requires some expertise; if something goes wrong during installation, it could result in thousands of dollars lost for repairs.

Also, keep in mind that both state and federal incentives may lower the up-front cost of purchasing and installing the Tesla Powerwall. Additionally, some utility companies may promote energy storage systems to their customers by allowing them to sell excess electricity back to the grid at more favorable rates than standard midday charging. Powerwall cost savings will depend on the size of your power pack, current electricity rates, and how much excess energy is available for sale.

Tesla Powerwall monthly costs

The Tesla Powerwall monthly cost also varies depending on how you use it. If you charge the battery using solar energy, your monthly cost will be minimal. However, if you need to draw power from the grid at night or during peak hours, your monthly bill will reflect that usage.

Keep in mind that when the Tesla Powerwall is used to provide power for your home, it will take precedent over the grid power. This means that if you are using power from the Tesla Powerwall and your utility company experiences a power outage, you will not have power from the grid.

What are the benefits of a Tesla Powerwall?

A Tesla Powerwall can provide a homeowner with a number of benefits, including:

Energy Security & Independence

A Tesla Powerwall can provide a homeowner with energy security and independence. This is because Powerwalls can store electricity generated from solar panels or from the grid so that the homeowner has a reliable source of power even during outages.

Time of Use Bill Management

A Tesla Powerwall can also provide a homeowner with a time of use bill management. This is because the battery is charged using electricity generated from solar panels or stored power during off-peak hours and this stored power can then be used at any time.

There are a number of different applications for a Tesla Powerwall, including:

  • Backup power support – the battery provides backup power in case there’s an outage;
  • Higher self-consumption of solar power – homeowners use more onsite solar energy and reduce their reliance on traditional utility grid supply;
  • Peak Shaving – homeowners store energy when they have excess and use it later to shave off part of their during peak periods; and/or
  • Time of use load shifting – storing power when the rates are low and using it during higher rate periods.

Clean power and more savings

A Tesla Powerwall can help homeowners achieve a number of clean power goals, including:

  • Net-zero energy usage – when paired with rooftop solar and net metering, the battery system may allow for a homeowner to generate more power than they consume and thereby produce excess energy that can be sent back into the grid;
  • Lower electricity costs – by charging the battery during off-peak hours and using stored power during peak demand periods, homeowners can reduce their electric bills;
  • Reduce greenhouse gas emissions – by using renewable sources like solar power or wind power to charge the battery, homeowners can reduce their impact on the environment.

Additional benefits of a Tesla Powerwall include:

Home power independence – if you’re concerned about blackouts after an emergency, the battery ensures you’ll always have power;

Rooftop solar support – homeowners can get additional energy produced by their rooftop solar panels stored in the battery system; and

Lower electric rates – during off-peak hours, homeowners can charge the Powerwalls to use during peak hours when rates are higher.

Solar companies in your area are likely to offer Powerwall for their customers. They can advise you on the best solar system for your home and install it as well.

FAQ: Tesla Powerwall Cost

Can you go off-grid with a Tesla Powerwall?

A Tesla Powerwall can be used in conjunction with solar panels, allowing you to generate and store your own electricity. Many people plan on using a Tesla Powerwall to disconnect from the grid entirely. In some situations this is possible, however, it depends on how much power you use and what type of solar panel system you have installed.

Before going off-grid the first thing you need to know is how much power your home uses. This will help you choose a Tesla Powerwall size that most accurately fits your needs. Some homes don’t use very much energy at night when their solar panels aren’t producing electricity; others might not use any at all if they’re equipped with batteries (like a Tesla Powerwall) that can store energy for future use. However, other homes will require enough solar power to meet their daytime usage and then recharge the battery at night when they’re not using any electricity.

Does Powerwall come with Tesla solar panels?

Powerwall is a battery that’s included with every Tesla solar purchase. You may store your solar energy for usage at any time, whether it’s during the night or during an outage. You can also charge your Powerwall with reliable solar power and use it to power your home at any time.

Tesla solar panels are installed on your roof in order to capture the energy from the sun. They can then store that power in a Powerwall for future use. You may also sell any excess solar power you generate back to your local utility, which means you get paid by the kilowatt-hour whenever you need an extra boost of electricity during high usage times. Tesla solar roof customers typically have an electric bill that’s either $0 or very low when they’re using their solar panel system.

What is the life expectancy of the Tesla Powerwall?

Most modern batteries last between 4 and 10 years if treated well. This means that you should assume that your Tesla power pack will still be working perfectly when it reaches its fourth year of service, but not necessarily afterward. The life span of lithium-ion batteries has been improving over time as scientists discover new ways to make these batteries more efficient.

However, the Tesla Powerwall does not last forever. All batteries wear out with use and will stop working properly once they become too old or too filled with power. For this reason, it’s important to consider your daily energy needs when deciding how many of these batteries you’ll need at home. A smaller battery pack may suffice for people who don’t require much electricity on a daily basis, but larger battery packs are ideal for those who exceed their current power demands by large margins throughout the day.
