Pros and cons of the best solar panel brands

Adding a battery to your home solar installation can be a complicated decision. First, you have to choose if you want backup power in an outage or just enough energy storage to offset some of your evening usage. Then, you have to decide which circuits in your home to back up and how much storage capacity you need. 

The home solar batteries on the market differ a lot in how they can perform these functions. 

• Some are designed to accept DC solar power input, while others connect only to the AC wires from your home’s electrical panel. 

• Some are modular, meaning their capacity can be expanded easily by adding battery modules under a central inverter and/or management system. Others come in one size only, and you can only expand their capacity by purchasing two or more. 

• Some come with sophisticated additional functionality, like charging from a backup generator or managing home circuits with smart functionality.

Every battery on our list combines some or all of these functions to meet various needs. While we recommend all the brands on our top 10 list, we prioritize modular batteries that can charge directly from either solar DC or AC output and can be easily adapted to the needs of many different kinds of homeowners.

Methodology: Our expert energy battery storage system rankings

SolarReviews’ battery rating methodology differs from other websites because we don’t simply rank performance and cost characteristics. In addition to technical specs, our team of solar experts emphasizes factors that encompass the company's success, which in turn provides long-term benefits to homeowners. 

We also consider the value of the batteries on a dollar-per-kWh basis and examine the battery company’s popularity among installers to get a holistic view of which batteries are the best. 

Here are the categories and weights of our battery ranking criteria:

Company financial visibility and strength (20%)

This category offers the most points based on a manufacturer’s financial performance and transparency. Companies are awarded points for being publicly traded, publishing financial statements, and maintaining high revenue and profitability.

Value (15%)

For this category, we evaluate a battery system based on its cost per kWh of storage, including installation costs, but before any incentives. For DC-coupled batteries, we add the cost of a SolarEdge hybrid inverter to the evaluation to fully represent the cost compared to AC-coupled batteries that include their own inverter.

Design and usability (14%)

This category examines a battery’s design flexibility. Points are awarded based on expandability, modularity, indoor and/or outdoor rating, and AC-and/or DC-coupled capability. Virtual power plant eligibility is also considered.

Warranty coverage (10%)

The warranty is an extremely important evaluation criterion when it comes to batteries. Ten years has been the industry standard for a long time, but several companies now offer warranties of 12 years, and Enphase now leads the industry with a 15-year warranty. Companies get points for length and having cycle-life or total energy throughput clauses in their warranties.

Energy storage capacity (10%)

This category represents the total capacity for a typical home battery. In the case of modular batteries, we evaluate using the most common or most functional size for the average homeowner.

Continuous power output (10%)

Here, we look at a single battery’s ability to output continuous power. In the case of modular batteries, we evaluate a battery with the number of modules needed to reach the inverter's maximum output.

Safety certifications (10%)

Safety certifications ensure a product meets certain standards, providing peace of mind for both installers and homeowners. Points were awarded for the presence of specific UL and UN certifications. 

U.S. investment (6%)

Our country needs home-grown businesses to bring us into a post-carbon world. This category tracks whether a company has offices or is based in the U.S., manufactures its equipment here, and regularly attends U.S. trade shows and industry events.

Industry opinion (5%)

Data for this category comes directly from our annual Solar Industry Survey. We ask installers which battery brands they will work with and award points weighted by the percentage of the industry that says they will install a company’s products. Full points are awarded to companies with at least 50% of installers saying they choose to install the battery.

How long do solar batteries last? 

Most home batteries are guaranteed to last at least 10 years, but many brands are starting to extend their warranties to 12 or 15 years. Battery warranties typically include a number of discharge cycles or energy throughput, as well. 

Batteries will continue to operate after their warranty period. Exactly how long your battery will work depends on its chemistry and how it’s used. For example, a battery that is completely drained more than once a day won’t last as long as one that’s used once a week. 

Keep in mind that batteries age and store less energy. Think about your smartphone battery—it probably doesn’t hold a charge quite like it did when you first got it. The same thing happens with solar batteries. Most battery warranties outline how batteries degrade with use and how much energy they can store over time.

Solar batteries have a shorter lifespan than solar panels, so you may have to replace your battery over the 25-year lifespan of your solar power system. Consider this when calculating the return on your solar investment and deciding on your financing options.

Are solar batteries worth it? 

Most homeowners don’t need a solar battery, but it can be beneficial to some. From a financial perspective, there are very few cases where solar batteries are worth it. 

If you live in an area that experiences frequent, prolonged power outages, home battery backup systems can keep your most important appliances running for a few days. When paired with solar panels, a battery could keep them running indefinitely without the utility.

Batteries can also be helpful in areas where solar buyback rates are low, net metering is not available, or utilities require time of use rates. In these cases, batteries can save a bit of extra money on your utility bill, but the savings are likely too low to ever see a real return on your investment. 

Overall, whether or not you need a solar battery storage system depends on what matters most to you! For some homeowners, the peace of mind of having backup power is worth the upfront cost. The best way to figure out the best battery solution for you is to speak to a local solar installer who can assess your energy needs and map out how a battery can benefit you.
