How Much Does a Solar Battery Cost? Price Factors and Considerations

You've likely heard about solar batteries if you've recently considered installing a solar panel system. Solar batteries allow you to store energy produced by solar panels for future use. Creating a 'hybrid solar system' by combining solar panels and solar batteries offers a number of benefits, including having access to dependable backup power and independence from your utility provider.

A key factor for any aspiring solar household is understanding how much they'll need to invest in a solar battery for later use when needed. In this blog post, we'll explore price factors and other considerations that play a role in solar battery costs, helping you make an informed decision on whether investing in one could be beneficial for you.

How Does Solar Battery Work?

A solar battery is a component that can be included in a solar power system to store excess energy. So that when your solar panels aren't producing enough electricity, such as at night, on overcast days, or during power outages, you can use the stored energy to power your home.

Solar panels generate the highest amount of electricity in the daytime, coinciding with the period of lowest energy consumption in homes. A standard solar system that is grid-connected sends extra solar energy to the grid. Meanwhile, when solar panels are connected to a home battery, extra electricity is stored in the battery rather than sent to the grid. So that when the sun sets and your solar panels are no longer producing electricity, the energy stored in your battery can be used instead of paying the utility for electricity.

What Is the Cost of Solar Batteries?

The specific cost of solar batteries will mostly depend on the size of the battery system needed to meet your energy requirements and the overall complexity of the installation. If you use more energy, it might be necessary to install more solar batteries to sufficiently power your home, thereby increasing the overall cost. According to the National Renewable Energy Laboratory (NREL), the estimated expense for a solar battery, including installation, amounts to $18,791. However, it is important to note that costs related to installation and permits can vary depending on the location and chosen installer. NREL's estimated cost specifically for the battery itself, without considering installation, is $16,007.

However, there are various incentives and rebates to minimize the expenses associated with installing a solar power system, which includes solar storage. One notable example is the Residential Clean Energy Credit, a federal tax credit that grants a 30 percent credit on the overall expenditure of solar installations, including battery systems. By taking advantage of this incentive, you can potentially save approximately $5,000 on the estimated price of a solar battery, as determined by NREL (National Renewable Energy Laboratory), prior to accounting for any supplementary costs.

Factors That Impact Energy Storage Costs

In addition to the size of the battery system, there are several other factors can influence energy storage costs, including -

  • The Battery Quality

The first thing to consider when installing batteries is the quality of the product that you choose. Despite the fact that all storage products on the market today meet strict safety testing requirements, the overall quality of energy storage systems can vary, and you can expect to pay more for higher-quality products.

  • Battery Manufacturer

As with anything else you purchase, the battery's price will depend on the brand you select. This is due to the fact that various brands manufacture their products differently and offer different services.

  • Battery Chemistry

Lithium iron phosphate (LFP) and nickel manganese cobalt (NMC) are the two primary lithium-ion chemistries for solar batteries. Since NMC batteries, such as the LG Chem Prime, have been around for a longer period of time, they are a bit cheaper than Enphase IQ (One of the LFP batteries). However, An LFP battery offers several advantages over NMC batteries, such as superior safety features, longer lifespan, temperature tolerance, high discharge rates, and reduced environmental impact. The LFP battery of Anker Powerhouse 767, specifically designed with these benefits in mind, provides a reliable and efficient energy storage solution.

There are also some homeowners who opt for lead-acid batteries because they are more affordable than lithium-ion batteries. However, lead-acid batteries have a shorter lifespan, and reduced capacity and require regular maintenance.

Benefits of a Solar Battery Storage System

A solar battery storage system offers several benefits that enhance the efficiency, reliability, and cost-effectiveness of solar power usage:

  • Energy Independence

With a solar battery, you can store excess solar energy generated during the day and use it later, reducing your reliance on the grid. This provides greater energy independence and resilience, especially during power outages or periods of high electricity demand.

  • Lower Bills

A solar battery allows you to utilize that stored energy during times when solar production is low, such as at night or during cloudy days. This means you can rely less on grid electricity and draw power from your battery instead. As a result, you can see a significant decrease in your monthly electricity bills.

  • Environmental Impact

By integrating a solar battery storage system with your solar panels, you can further reduce your carbon footprint. The stored energy allows you to rely less on fossil fuel-based grid electricity, promoting the use of clean, renewable energy and contributing to a more sustainable future.


In conclusion, understanding the cost of a solar battery in 2023 is crucial for anyone considering investing in solar energy storage. The price of a solar battery can vary based on factors such as battery capacity, technology, brand, and installation costs. On average, solar batteries can range from a few thousand dollars to tens of thousands of dollars. It is important to assess your energy needs, evaluate available incentives and rebates, and compare quotes from reputable suppliers to determine the most suitable and cost-effective option for your specific requirements. Additionally, keep in mind that while the upfront cost may seem significant, a solar battery can provide long-term financial savings by maximizing self-consumption, optimizing energy usage, and providing backup power during outages.
