Home Solar Battery Systems FAQ

SunVault Storage is an energy storage system designed and manufactured by SunPower. This solar battery is a Lithium Iron Phosphate battery instead of the conventional Lithium-Ion batteries used by the many devices we own today.

The SunVault Home Battery Storage is used to store the renewable energy your solar panels produce during the day. When your solar panel system produces more power than you can use, the energy is stored in the solar battery for later use.

SunVault Storage is a two-part system that includes the energy storage unit and Hub+. All customers can also enjoy SunPower’s mobile app to view their performance and manage their system’s settings.

The benefits of owning a solar battery storage solution from SunPower include:

  • A higher continuous power rating of 6.8 kWh – Run more appliances at once.
  • Store energy produced during peak daylight.
  • Avoid rising utility costs during peak hours.
  • Keep your home powered when your solar panels produce less.
  • Maintain power during a power outage.
  • Be in control of your home energy use.
  • Greater energy independence.
  • More savings on your utility bills.
  • Emergency backup power.
  • Reduce your carbon footprint by using more clean energy.

SunPower manufactures all the components of the solar energy system. With a rich history in solar energy and a strong focus on innovation, they pride themselves on delivering the highest-quality products that work best for their customers.

SunPower has been a leader in the solar industry for over 35 years. They focus on creating high-quality, reliable products that last longer than most. Accompanied with the most complete warranty, backed by a single company, you can be assured your investment is safe and will yield a good return.

How much money you save will depend on your energy usage, utility rate and structure, and more factors. When you receive a proposal from our team, an estimate of your savings based on your current electricity usage will be included.


Yes, the SunVault system comes with a 10-year warranty as part of the Complete Confidence Warranty.

This warranty ensures that the battery will be free of material and workmanship defects and retain at least 70% of the initial useable energy capacity until one of the following: 

  • 10 years from the date that the Storage System is installed
  • The date whereupon the Storage System has incurred 38.0 MWh energy throughput
  • The Storage System has incurred 4,000 cycles

The cost of SunPower’s battery backup solution is dependent on your home’s energy needs. To get a comprehensive quote for a solar battery, click here.

Home solar battery systems are designed to work with your solar panels to store power generated by the sun. When your home’s energy needs are being met, excess solar energy is used to charge your battery backup. During times of low solar output, such as at night or on cloudy days, your battery system will discharge to keep your appliances running.

Your system may also draw from the grid during off-peak times to prevent you from paying peak rates. This allows for true energy independence and the flexibility to charge your battery with solar during sunny days or use it as backup power when needed most.

Battery storage gives you access to cheap electricity when you need it most, saving you money on electricity bills and reducing demand on the grid during peak hours.

Solar plus storage is an alternative to a standard solar panel installation that allows you to charge your battery backup with excess power generated by your solar panels. This eliminates the need for expensive utility electricity and will enable homeowners to protect themselves from power outages and gain great energy independence.

Indoor installation is recommended for your SunVault system. However, outdoor installations are possible depending on your climate, shading, and the probability of severe weather.

This depends on how much energy your appliances require, how many batteries, and the context of the question.

Suppose there is a power outage for an extended period, and you need to power only the essential appliances in your home. Using only one solar battery can provide enough backup for up to 3 days.

There are two SunVault storage solutions. The first has a rated capacity of 13 kWh, approximately half of what the average household in America consumes daily.

The second is a 26 kWh battery, which holds enough capacity to power your home continuously for a day, based on typical household energy consumption.

The term ‘off-grid’ can mean different things.

Whether you’d like to have less reliance on the utility grid for power or disconnect from the grid completely*, SunVault + solar panels offers an excellent off-grid solution and will be able to give you greater energy independence.

*For those looking to go completely off-grid, we recommend you to get in touch with an Authorized SunPower Dealer to explore your energy storage options.

Net metering is a policy that allows you to have solar panels installed on your roof, which will then get credited for the amount of energy it produces. The credits can be used to power your home or get bill credits at the end of the month. To use net metering, you need to have a net metering agreement with your utility company.

SunVault has a smart piece of software that allows your home to draw from the grid during off-peak times and discharge excess electricity during peak times so you can maximize your savings. You will need a ‘time-of-use’ tariff to take advantage of this billing method. 

Investing in a SunPower solar battery storage system is an excellent choice for homeowners interested in increased energy independence and sustainability. With a 10-year warranty and quality construction, the SunVault is designed to last and will be able to provide you with power that can’t be matched by alternative battery storage solutions.

The SunVault offers a higher continuous power rating than competitors on the market and works well for those looking to go off-grid or who need emergency backup power. It’s also worth noting that investing in SunVault will benefit your wallet as it can help save you more money on your utility bill.
