Does SunPower Offer Tesla Powerwalls?

SunPower direct does not sell Tesla Powerwalls, it offers the SunVault home battery storage solution. However, the SunPower® Equinox™ solar panels can be paired with leading battery storage solutions, including the Tesla Powerwall. This gives SunPower solar customers more options to select the best home battery for their energy storage needs.

While SunPower doesn’t sell Tesla Powerwall solutions directly, you can purchase them through SunPower dealers and Certified Powerwall Installers, like Solar Technologies, that have the unique ability to offer SunPower solar panels along with the Powerwall.

What is a Tesla Powerwall?

The Tesla Powerwall is a rechargeable lithium-ion battery designed to store energy at a residential level for backup power and self-consumption of solar power generation. It’s also scalable, so it can be easily expanded to meet the needs of larger homes or businesses.

The Powerwall is compact, integrates easily with your existing solar system and is engineered to require no maintenance for ten years. It optimizes your energy usage by automatically switching you over to battery when your solar production is lower than your consumption. With a 10-year warranty and the ability to charge during off-peak hours, Powerwall shifts solar power from day to night, effectively maximizing its use.

Frequently Asked Questions About the Tesla Powerwall

Now, let’s address some of the most common FAQs about the Tesla Powerwall, including how it works, how much it costs, and more.

How Does the Tesla Powerwall Work?

If you’re already getting solar power for your home, Tesla Powerwall allows you to maximize the benefits of your existing solar panel array. The Powerwall stores electricity generated by solar panels or from the grid in its lithium-ion battery.

When the grid goes down or the solar panels are not producing enough electricity, the Powerwall can automatically switch to battery power to provide electricity to the home. When the grid is up and the solar panels are producing excess electricity, the Powerwall can charge its battery using that excess electricity.

How Much Does a Tesla Powerwall Cost?

The cost of a Tesla Powerwall varies depending on how much electricity your home uses and how many batteries would be needed to power the home. While home batteries can be pricey, the cost can be offset through financial incentives like California’s Self-Generation Incentive Program (SGIP) or through tax incentives. Including installation, a Tesla Powerwall will cost between $12,000–$16,500 before incentives. 

Although the Powerwall may cost more than other home batteries, it has a higher storage capacity and power output – you can read our full Review of the Technical Details of the Tesla Powerwall to learn more. It’s important to note that the price is also based on how many Powerwalls you order: without the installation hardware and fees, one Powerwall is $10,500, but you can purchase two for $17,000 (or $8,500 each) and save some money.

Does Tesla’s Powerwall Come With a Warranty?

The Tesla Powerwall’s 10-year warranty is competitive when compared to other home batteries. It comes with the standard product and performance warranty, workmanship warranty and more, but what makes it unique is that it also comes with an unlimited cycle warranty.

Can the Tesla Powerwall Be Used in All Locations?

The Tesla Powerwall can be used in most locations. Most California homeowners can enjoy benefits but it is important to check with your Certified Powerwall Installer to determine if the battery is suitable for your home energy needs. Factors such as the local climate, the availability of grid power and solar resources may affect the suitability of the Powerwall for your particular location. 


Tesla’s Powerwall is an innovative way to store energy at a residential level and maximize the benefits of your existing solar panel array. It’s compact, integrates easily with your existing solar system and requires no maintenance for ten years. 

Powerwalls can be purchased from Tesla or from a Certified Powerwall Installer like Solar Technologies. If you want to change the way you power your home and save with clean energy, contact us today for a free customized quote.
