Best solar batteries for your home in 2025

We reviewed the top solar batteries and found that the Villara VillaGrid comes in at number one.

Home batteries can be a great investment for your home, though we’ll admit they’re not for everyone. Adding storage to your solar panel system makes perfect sense if your area doesn’t have a consumer-friendly net metering program, you face frequent power outages, or you simply want more independence from your utility company. 

If that’s you, the next step is weeding through all of the home storage options on the market. Choosing the best battery boils down to factors like battery chemistry, performance, customization, warranty, and cost. We looked at all these factors in dozens of models featured on the EnergySage Marketplace to determine the best batteries of 2025. 

Five brands stood out: Villara, Tesla, Panasonic, HomeGrid, and Duracell Power Center.

1. Villara VillaGrid: Best efficiency & warranty

  • Price: Not available

  • Capacity: 11.5 kWh 

  • Roundtrip efficiency: 98.5%

VillaGrid battery

The Villara VillaGrid battery stands out with its industry-leading, 20-year  warranty, made possible by its special lithium titanium-oxide LTO battery chemistry. Unlike more traditional lithium-ion batteries, LTO has better recharge capabilities and doesn't contain any carbon, which makes it extra safe. The VillaGrid also has a 98.5% efficiency rating—the best on our list—and offers the highest peak power output, making it a great choice if you have power-hungry appliances that need a strong surge of energy to start up.

The VillaGrid has many advantages, but there are better options if you need long-duration backup power. The 11.5 kilowatt-hour (kWh) battery can drain relatively quickly, depending on what you're powering.

2. Tesla Powerwall 3: Most popular

  • Price: $926/kWh

  • Capacity: 13.5 kWh 

  • Roundtrip efficiency: 97.5%

Tesla Powerwall 3

The Tesla Powerwall 3 is a big step up from the Powerwall 2 and a popular pick among EnergySage customers. It has solid peak and continuous power ratings, which provides ample power for most homes. The Powerwall 3 comes with an integrated hybrid inverter, which means it can be AC-coupled or DC-coupled and easily added to an existing solar system through a retrofit installation. 

If you have a shady roof and want panel-level optimization for your solar panel system (e.g., microinverters), you might consider skipping the Powerwall 3. You'll get the most out of the Powerwall 3 by DC-coupling it, which means using the Tesla hybrid inverter that comes with it.

3. Panasonic Evervolt: Price & warranty runner-up

  • Price: $843

  • Capacity: 18 kWh/kWh

  • Roundtrip efficiency: 94%

Panasonic Evervolt batteries

The Panasonic Evervolt Home Battery is our runner-up in affordability, warranty term, and degradation rate (how much its ability to hold a charge decreases over time). While it might not be number one in any category, it’s one of the most affordable batteries and a strong pick all around. It also comes with an integrated hybrid inverter that can be AC- or DC-coupled to fit your unique installation needs.

The Evervolt is the least efficient battery in our top five, though it’s still higher than most in the market with an impressive 94% roundtrip efficiency. While it has plenty of capacity, it isn’t the most powerful pick, so if you experience extended outages often, the Evervolt might not be for you.

4. HomeGrid Stack’d Series: Best scalability 

  • Price: $973/kWh

  • Capacity: 38.4 kWh 

  • Roundtrip efficiency: 98%

HomeGrid battery

The HomeGrid Stack’d Series is a powerful and efficient battery that's particularly good for those interested in going off-grid: It's the most scalable battery, with the highest maximum usable capacity by a landslide (576 kWh). The average person won't need a battery system this big, but the great thing about the Stack’d Series is that you can scale the capacity up or down to better meet your needs. 

If you already have solar and want to add a battery, skip this one—it can only be DC-coupled. It also doesn't have the strongest warranty, guaranteeing only 60% of initial capacity by year 10. 

5. Duracell Power Center Max Hybrid: Best price per kWh

  • Price: $564/kWh

  • Capacity: 15 kWh 

  • Roundtrip efficiency: 96%

Duracell home battery

You’re used to powering your TV remote with Duracell batteries, and now you can use them to power your entire home. Of our top five picks, the Max Hybrid battery provides the highest continuous power, meaning you can power many devices simultaneously. It’s also super scalable and way more affordable than most batteries based on quotes through the EnergySage Marketplace. 

The biggest downside of the Max Hybrid is that its smallest size is 15 kWh, which is pretty big. If you don't need that much capacity, you’re probably better off with a different battery.

Just like there are different types of alkaline batteries for your devices and gadgets, there are different types of solar batteries. You’ll want to install a battery with the right chemistry and coupling for your unique needs. 

Most batteries are lithium-ion

A battery's chemistry refers to the primary compound used to store electricity inside it. Today, most home batteries use lithium-ion chemistry, which can be broken down into three primary categories: Lithium Nickel Manganese Cobalt Oxide (NMC), Lithium Iron Phosphate (LFP), and Lithium Titanium Oxide (LTO).

A couple of ways to couple batteries

A battery's coupling refers to its configuration relative to your solar inverter and electrical panel. There are two ways batteries can be coupled: alternating current (AC) coupling and direct current (DC) coupling.

We evaluated dozens of battery models quoted through the EnergySage Marketplace to determine which solar batteries are best. Here are some of the most significant factors we used to compared them:

Performance 

Warranty

Price

It generally costs about $9,400 to install a 13.5 kWh battery (after the federal tax credit).  

Choosing a costly battery can be worth it. Just make sure you understand why the battery is more expensive than the average to ensure it's worth it.

We think the VillaGrid is the best battery overall, but that doesn't mean it's the best battery for you. Some batteries are ideal for certain setups but won't work in others. Here are some questions to think about to find the best battery for you:
