Solar batteries are unique devices that store excess energy from your solar panels. Rather than letting it go to waste, solar batteries take that energy and keep it so you can put it to use when solar panels don’t provide enough energy. If you’re considering solar batteries, it is critical to understand how much they cost.

On average, a solar battery costs between $8,000 and $10,000 without the installation process. Once the installation goes into the price, solar batteries can cost as high as $20,000 to put in a home.

If you’re interested in learning more about how much solar batteries cost, you’ve come to the right place. Read on to learn more about price, the number of batteries necessary to power a home, and how long solar batteries typically last. The more you know, the better prepared you will be to invest in a solar battery.

How Much Does a Solar Battery Cost?

Is It Worth Getting a Battery With Solar?

Solar batteries are pricey. If you are interested in one, you need to be ready for an extensive investment. Is it worth purchasing a battery with solar, or are you better off sticking with just your solar panels for energy?

In the long-run, solar batteries are worth your money. If you already have solar panels, it makes sense to complement the system with a solar battery to collect excess energy and store it for the times you need additional energy.

Solar batteries can keep your home in operation if the power from your solar panels fails. They can also reduce the energy you need to draw from the grid, allowing more for the rest of the world. Solar batteries will save money and provide peace of mind when your solar panels aren’t working as well as they should.

How Many Solar Batteries Are Needed To Power a House?

Maximizing your money with solar panels requires investing in enough batteries to hold enough energy to power your home if the panels aren’t collecting or producing enough energy. 

If your panels don’t produce enough energy, two to three solar batteries are necessary to power the home. You should have at least two of them on hand to hold enough energy in case things go wrong with your solar panels.

On the other hand, it only takes one battery to keep the power going if the grid is offline. It’s up to you to determine what you are willing to risk and how much power you need on hand if something goes wrong with the grid or your solar panels.

How Much is a Good Solar Battery?

It may be tempting to purchase a cheaper solar battery instead of a more expensive option. The cheaper varieties can be $8,000 or less, while the pricier versions can be $10,000 or more. Despite the price difference, it’s often better to go with a pricier battery and installation if they have a quality reputation on the market.

A good solar battery and installation are worth the additional investment because it is:

  • Guaranteed to be of quality
  • Installed by a person who knows what they are doing
  • Able to last much longer than cheaply made varieties

If you’re investing, you might as well pay a little more for the best options available.

It’s critical to read reviews and customer opinions before investing. Purchase a solar battery and installer with a track record of quality, as it’s all too easy to spend a lot of money on a product and installer and receive a terrible battery in return.

How Long Do Solar Batteries Usually Last?

Home solar batteries won’t last forever. If you want to go with the product for your home, be prepared to replace them every five to fifteen years. Once they wear out, they won’t be able to store energy and provide power for your home in case of a power outage.

Here are a few factors that might impact the lifespan of your solar panels:

  • Type of solar battery
  • Temperature
  • Usage
  • Maintenance
  • Warranty

These can affect how long they live.

The standard solar panel system lasts twenty to thirty years, so your batteries will not live as long as your panels. Incorporate replacements into your budget to ensure you can afford multiple batteries over that period.

What Are the Types of Solar Batteries?

As with any other product, there are multiple types of solar batteries on the market. Each has something different to offer users. Some are cheaper than others, so it’s critical to assess your budget to determine which battery type is the best fit for your life. There are four common types used on solar panel homes.

There are four main types of solar batteries:

  • Lithium-ion
  • Lead acid
  • Flow
  • Nickel-cadmium

These provide different forms of energy to homes.

It’s up to you to determine which battery version works best for your solar batteries. Lead acid is the cheapest and most reliable, lithium-ion is the newest version, flow is an emerging technology with hydrogen, and nickel-cadmium offers durability, often used in the aircraft industry. It’s likely more varieties will emerge as technology continues to grow and change.

Final Thoughts

If you are interested in solar batteries, be ready to pay a steep price. Solar batteries cost between $8,000 and $10,000, and the price quickly goes up when considering the installation process. When considering that some homes need two or three batteries to charge, you should be prepared for a cost worth a solid down payment on a home. 

We hope this information was helpful! There is a lot to consider if you are interested in a solar battery, and one of the most critical components is the expense. It might seem like a steep price to purchase a solar battery, but it’s worth the investment if you want to have additional energy on hand. Solar batteries are valuable tools in an energy-efficient home.
