Best Solar Batteries of 2023 (1)

Solar batteries are a smart investment for residential energy storage and DIY solar projects. Peoplewho want to go off the grid can use solar batteries to store excess energy that can be used at night or on cloudy days. A few solar batteries come in handy if you live in an area with unreliable utilities. You can also use solar power battery storage to run RVs, boats, golf carts and more.

As you compare solar batteries, keep in mind that capacity tells you what the battery can storeand is measured in kilowatt-hours (kWh). Power shows a battery's output capability and is measured in kilowatts (kW). Look for a solar battery with a depth of discharge at least 40% or higher and round-trip efficiency around 80%.

  • Capacity:The average American household uses about 30 kWh each day, and a typical solar battery has a capacity of around 10kWh.
  • Depth of discharge: The depth of discharge shows how much of your battery capacity can be used before potentially shortening its life span. The higher the DoD, the more usage you'll get from the battery's capacity.
  • Power: Power shows a battery's output capability. The amount of power a battery can deliver at once is displayed in kilowatts (kW).
  • Round-trip efficiency: Round-trip efficiency is the difference between the amount of energy used to charge it and the available amount of energy. Like the depth of discharge, a higher round-trip efficiency percentage is a better value.

The last thingto consider is the battery’s warranty and guarantee. Since battery performance declines over time, a warrantythat guaranteesa number of cycles or years of good performance is essential. It should also guarantee the battery maintains a specific capacity.

What is a solar battery?

A solar battery is an energy storage option for those with solar panel systems. With the increased use of solar power, solar batteries are more popular with homeowners who want to offset electricity costs and those living or camping off-grid.

Solar generators and portable solar chargers are types of solar battery storage systems. While solar generators are typically affixed to their location — usuallyhouses, campers or boats — a portable solar charger is a smaller, often hand-held device typically used to charge phones or other electronics. Some solar generators are available as all-in-one kits, but you can buy components separately as well.

Types of solar batteries

There are multiple battery types to consider when choosing solar batteries. Which type is bestvariesbased on your needs and whether you prioritize cost efficiency, safety or environmental impact.

Deep-cycle battery
The term “deep cycle” refers to the battery’s ability to complete a discharge-recharge cycle several times. Deep-cycle batteries are designed to keep a steady flow of power over an extended period. Thick lead plates help prolong the battery's life. Lithium-ion, flooded and gel batteries are types of deep-cycle batteries.
Lithium-ion battery
Lithium-ion batteries are an excellent choice because they are relatively low maintenance and easy to install. The benefits of a lithium-ion solar battery include higher energy density, less weight and increased life span. Lithium-ion batteries are considered a revolution in home energy storage solutions.

Lithium batteries have the added advantage that their voltage stays relatively constant as it discharges. In a lead-acid battery, the voltage decreases as the battery discharges. So, in order for a lead-acid battery to maintain its output, the current draw increases as the voltage drops. This, in turn, discharges the lead-acid battery more quickly. Lithium batteries do not have this drawback.

Lithium-polymer battery
Similar to lithium-ion, lithium-polymer batteries are more resistant to issues like overcharge or electrolyte leakage. They are also more expensive and don't usually last for as many cycles as lithium-ion batteries.
Flooded lead-acid battery
Also known as wet-cycle batteries, flooded lead-acid batteries contain liquid in an open container and disperse hydrogen gas. These batteries are cheaper but require more maintenance because the battery must be kept upright and well-ventilated. The battery also needs to be monitored and regularly refilled with distilled water.
Sealed lead-acid battery
This valve-regulated battery is considered the maintenance-free option in sealed lead-acid (SLA) batteries. They are designed to keep the battery from reaching its gas-generating limit while charging, which prevents water depletion and gas dispersal. This also means that the battery can never be completely charged.
Nickel-cadmium battery
Ni-cad batteries have a long lifespan if properly maintained. This is one of the more rugged battery types available, but they occasionally require a full discharge to keep their longevity. Be aware that cadmium is toxic, so this battery cannot be disposed of in landfills.
Saltwater battery
If you’re looking for clean and environmentally friendly energy, a saltwater battery is a good choice. Like lead-acid batteries, saltwater batteries offer a natural alternative for clean energy storage. The electrolyte is saltwater, which is nontoxic and nonflammable. These batteries are maintenance-free and have good longevity.
Solar gel battery
A gel battery, or gel cell, is similar to a sealed lead-acid battery. This battery also uses a gel electrolyte. Unlike other lead-acid batteries, you don't need to keep it upright — it handles movement very well, which makes it a smart choice for campers, vans and boats.

How do solar batteries work?

Solar batteries can be installed alongside your solar panel system to store the excess energy it produces. When the panels don't produce power at night, you can use the stored energy instead. Many solar battery storage options come with an inverter to convert the stored DC power to the AC power you need, but some require you to buy the inverter separately.

You can then use it as a solar battery generator to power electricity needs. This helps people looking to mitigate electricity costs, prepare for disasters or be completely off-grid. Homes still on the electrical grid can offset their consumption with backup energy and run on battery power until the storage is depleted.

The amount of electricity a solar battery can deliver at once is measured in kilowatts (kW). Kilowatt-hours (kWh) refers to the total amount of energy utilized over an hour. The U.S. Energy Information Administration (EIA) states the average American home consumes 901 kWh per month, or 30 kWh a day. With a battery that provides 2.5 kWh, you would need 12 batteries for sufficient daily power.

Since solar batteries self-discharge, the stored solar energy depletes over time. The rate of self-discharge depends on the type and age of the battery. Newer batteries typically deplete at a rate of 1% to 2% per month, whereas older batteries could deplete by as much as 2% per week.

Residential solar panel arrays don’t usually require solar batteries. Still, solar panel battery storage lowers yourutility bills, protects you from power outages and reduces your carbon footprint. If you already have solar panels, solar batteries work to store energy for the future. However, most popular solar batteries like Tesla Powerwall and LG Chem RESU aren’t designed to go completely off the grid.

Solar battery FAQ

Small solar batteries run between $200 and $2,000. However, a quality battery for residential solar energy storage can cost up to $7,000 or more. When comparing solar battery prices, you should also consider the cost of battery storage per kWh (kilowatt-hour), which ranges from $400 per kWh to $750 per kWh.

Most homeowners need between two and five solar batteries to effectively power a house. Depending on your energy needs, you can connect several batteries in a series or parallel battery bank with interconnecting cables. Solar batteries are stackable, meaning that you can install multiple batteries with your solar storage system to reach the right capacity for you.

Solar panels are expensive because of the materials required to produce them. Prices are expected to drop as solar technology advances.

Generally, fully charged solar batteries should power your home for 12 to 24 hours. Variables like your household energy consumption, the capacity of your batteries and whether you’re connected to an electricalgrid determine exactly how your long solar batteries last. A solar battery’s lifespan can be anywhere between five and 15 years. You can extend a battery’s life with proper maintenance and by protecting it from extreme temperatures.

A battery bank is a collection of batteries that are connected. A battery bank allows for more power storage than you get from a single battery.

Are solar batteries worth it?

Solar batteries are an energy-efficient way to generate backup power. However, for those who just want to go off the grid, diesel generators might be cheaper in the short term. Solar batteries make a lot of sense if you live in an area where utilities are unreliable or if you want to go off the grid while using renewable energy. Solar batteries store excess energy produced by your solar energy system so that you can tap into it whenever your panels don’t produce enough electricity.
