How Much Does SunPower’s SunVault Battery Storage Cost?

When many people hear about SunVault battery storage for the first time, one of the first questions that comes to mind is: how much does it cost?

There are a few things to remember when we talk about the cost of batteries. First, while home batteries like a SunPower SunVault can be expensive, a portion of the overall cost can be offset through financial incentives, rebates, etc. 

Secondly, there are many variables that impact how much it will cost for each individual homeowner, like how much electricity they use and how many batteries are needed. This can make it tough to know exactly how much your overall home battery investment will be without diving into the details. 

Finally, home batteries are an investment in your home’s future and can provide peace of mind by protecting your home and family during outages, blackouts and rising energy costs

Watch this short video overview of the SunPower SunVault™ Storage system to see the components that will come with your system:

Here are 3 things to help determine how much SunVault battery storage will cost you:

1. Batteries are expensive, but the cost can be reduced.

Home batteries are made with high-grade lithium-ion and require an advanced manufacturing process. Because of this, battery storage can be pricey. A five kilowatt (kW) solar energy system can cost anywhere from $9,000 to $15,000 depending on where you live and which home battery you choose. A SunVault storage battery system can cost anywhere from $12,000 to $28,000 or more depending on a variety of factors. This price estimate includes system installation. 

While evaluating your backup power options, it’s best to prepare yourself to make a significant investment for a storage solution that will store enough energy to power your home in the event of a power outage or blackout. Fortunately, there are several ways you can reduce these costs, including financial incentives like the Self-Generation Incentive Program (SGIP) in California and through tax incentives and benefits.

2. Installation costs and additional factors can impact the overall price for home battery storage.

As previously mentioned, figuring out the cost of installing a home battery isn’t as straightforward as looking up the price of the battery and knowing what your investment will be. The baseline price of a home battery is only one piece of the equation. Depending on your home’s electrical setup, installation costs can vary. 

Another thing to consider is if you’re adding a battery to an existing solar system or installing the solar panels and home battery simultaneously. You’ll also be evaluating which appliances you’ll want to power during an outage and what your overall energy needs are to see how many batteries you’ll need for your home. The size of your system will vary depending on whether or not you want to back up your essentials or if you are looking to optimize your comfort level during an outage for a longer period of time. When you meet with your energy consultant, you’ll have the opportunity to select the items in your home that you’d like to backup: 

Back Up Your Essentials (13 kWh or  26 kWh single-inverter system):

  • Well pump*
  • Electrical outlets (120 V) 
  • Garage door
  • Router, TV, and computer 
  • Refrigerator 
  • Freezer 
  • Home security system 
  • Interior lighting 
  • Microwave oven 
  • Gas stove or oven 

Backup With Additional Comfort (26 kWh or  52 kWh multi-inverter system):

  • Electric water heater 
  • Electric stove or oven 
  • EV charger*
  • HVAC unit*

*Additional details & information may be available for review. Please check with your solar energy consultant. 

In terms of the installation itself, your cost will vary depending on who you choose to install your system. The placement of your SunVault system may also impact the overall cost for installation. It is recommended to install your SunVault in the garage, or an area that does not receive direct sunlight or get too hot. You will need to add a shade structure to protect your unit if your options are limited to outdoor installation in direct sunlight.

3. Battery storage can be a wise investment for peace of mind. 

It makes sense to invest in solar + battery storage if you’re concerned about your family’s comfort and safety. The costs of a battery can be offset by reduced electricity bills from your solar panels, rebates and incentives, and peace of mind knowing your family will never be left without power. Batteries also make it possible for homeowners who may not have access to traditional utility services to live comfortably off-grid.

Whether you want to reduce your reliance on the grid or enjoy peace of mind protection from outages and blackouts, SunVault battery storage is one of the most advanced and energy-efficient energy storage solutions on the market today.
