As subject matter experts, we provide only objective information. We design every article to provide you with deeply-researched, factual, useful information so that you can make informed home electrification and financial decisions. We have:
Sourced the majority of our data from hundreds of thousands of quotes through our own marketplace.
Incorporated third-party data and information from primary sources, government agencies, educational institutions, peer-reviewed research, or well-researched nonprofit organizations.
Built our own database and rating system for solar equipment, including solar panels, inverters, and batteries.
We won''t charge you anything to get quotes through our marketplace. Instead, installers and other service providers pay us a small fee to participate after we vet them for reliability and suitability.

A typical home needs about 11.4 kilowatt-hours (kWh) of battery storage to provide backup for its most critical electrical devices. In 2024, a battery with that capacity costs $9,041 after federal tax credits based on thousands of quotes through EnergySage.
If you''re looking at solar batteries, it''s probably because you either frequently experience power outages, or your utility company may not provide compensation for excess electricity your solar panels send to the grid. You could also just have access to really great incentives. If you fall under one of these categories, solar batteries are probably worth it. They could save you thousands of dollars over a decade.
If you think you need a battery just because you have solar panels, maybe reconsider. Batteries can significantly increase the overall cost of your solar system, sometimes even doubling the price. In many cases, solar batteries aren''t worth it yet. We''ll help you decide if investing in a battery will pay off.
Solar battery cost varies dramatically across brands. Different companies offer different battery sizes, so the easiest way to compare costs is to look at the price per kilowatt-hour (kWh). Kilowatt-hours measure the capacity of the batteries, or how much energy they can store at once.
On EnergySage, Tesla offers some of the most affordable batteries at about $1,000/kWh. You''ll typically pay the most for Generac batteries, which cost about $1,961/kWh.

Battery prices aren''t consistent from state to state. Based on EnergySage quotes, you''ll pay the most for a battery installation in Oregon and the least in California. Installers may be less familiar with batteries in certain states and charge more for labor. Or, they may tend to carry more expensive battery brands in your state, which can also drive up the price.
The optimal battery size also varies by state based on weather, policies, electricity usage, and more. As we explain more below, battery size and cost go hand-in-hand. Take a look at the average battery cost in your state:

The most significant cost factor of a battery installation is the equipment itself. What battery are you installing and how many do you need? What chemistry does the battery use to store energy and does it come with an inverter?
Equipment costs typically account for 50-60% of the price of an energy storage system. Labor and project planning make up the bulk of the remaining costs, so choosing the right installer is key.
The first thing to consider when selecting a battery is its quality. Energy storage products must meet rigorous safety testing requirements, but there are still variations in the overall quality of batteries, which primarily comes down to chemistry.
Most home batteries use some form of lithium-ion chemistry to store electricity. The two most common types of lithium-ion batteries are nickel manganese cobalt (NMC) and lithium-iron phosphate (LFP). NMC batteries tend to be more power-dense while LFP batteries are more efficient, tend to last longer, and are slightly safer. On the EnergySage Marketplace, LFP batteries are often 30-50% more expensive than NMC batteries, though this still varies by brand.
If you just want to back up a few critical loads, your solar battery cost will be on the lower end. If you''re looking to back up your whole home or go off-grid, expect to pay a lot for battery storage. We''re talking $20,000 to over $80,000 in some cases.
Compared to solar panel systems, batteries are a bit less customizable in terms of size. It''s usually pretty easy to add or subtract a single solar panel to get the ideal system size. It''s more challenging to fine-tune the size of the battery, though this is improving. Some companies today offer very modular options for more flexible configurations.
Batteries store direct current (DC) electricity, but your appliances use alternating current (AC) electricity. You need an inverter to convert the DC electricity stored in your battery to usable AC electricity. Some batteries come with a hybrid inverter that also works with solar or a storage-specific inverter. If yours doesn''t, you''ll need to purchase one separately. The inverter could add a couple thousand dollars to your system cost.
Energy storage installations require significant electrical work. If you install storage at the same time as your solar system, you save money by getting the electrical work completed simultaneously. If you retrofit a battery to an existing solar system, you''ll pay extra for labor, wiring, and in some cases, equipment.
As we said, big storage projects cost a lot of money. Most home battery systems today aren''t large enough to cover all your electricity usage. This means you need to put specific circuits onto a critical load panel. A critical load panel functions like a secondary electrical panel. On the panel, you include the essential circuits that you want to remain energized in the event of an outage.
While the critical load panel itself isn''t costly, the electrical work required to install one can add up. Some battery companies today offer load management devices that make critical load panels unnecessary. If you have or choose to install a smart electrical panel, you also won''t need a separate critical load panel for your battery.
If electricians will already be pulling circuits during your storage installation, it''s worth considering a smart electrical panel to get the most out of your storage system. Several companies, like Span, Lumin, and Schneider, now offer smart electrical panels that provide circuit-level monitoring and controls. You can set schedules and remotely turn each circuit on and off depending on the time of day and remaining power in your battery.
Smart electrical panels are more expensive than critical load panels, but the flexibility they provide can be well worth it. Why decide today which appliances and circuits you want to back up for the next 10 years when a smart electrical panel lets you update those preferences in real time?
There''s no one-size-fits-all storage solution. It''s important to get multiple quotes and compare prices, the same way you would for other big purchases like a car or a new HVAC system.
If you use EnergySage''s online quote comparison platform, solar and storage installers will compete for your business, helping drive down the price. We vet all the installers on our platform, so you can feel confident that you''re getting a quality solar-plus-storage system.
