Solar batteries: Are they worth the cost?


“Are solar batteries worth the cost?” This question has become increasingly prevalent as renewable energy technologies continue to evolve and gain traction in the mainstream. With rising concerns about climate change and the transition towards sustainable energy sources, the debate surrounding the value of solar batteries has captured the attention of homeowners, businesses, and policymakers alike. As we delve into this topic, it becomes crucial to explore the various factors influencing the cost-effectiveness of solar batteries and their potential impact on the broader energy landscape.

According to data from the U.S. Department of Energy, the average cost of a home solar + storage system in the United States is currently around $15,000. This includes approximately $7,000 for the solar panels and $8,000 for the storage system. If you already have solar panels installed and are looking to add storage capacity, you can do so at a cost ranging from $12,000 to $22,000 for the batteries. Consult with your solar installer to inquire about adding batteries to your system.

If you purchase batteries separately or a solar + storage system, you may be eligible for federal tax credits. The Federal Solar Investment Tax Credit (ITC) is a nationwide incentive established by the federal government in 2006. The ITC allows homeowners to receive a federal tax credit equal to 30% of the system's cost for solar systems installed from 2022 to 2032. For solar systems installed from 2033 to 2034, the ITC gradually decreases to 26% and 22%.

Furthermore, some states and regions also have additional incentives for solar batteries. For example, California offers solar battery rebates of up to $2,500.

What are the pros and cons of solar batteries?

Pros of solar batteries:

1. Backup power source:

Solar batteries can run key appliances when the power goes out, making them popular in areas that experience frequent blackouts. 

2. Increase energy independence: 

When you have a battery, you rely less on the utility company. Take your power into your own hands!

3. Decrease carbon footprint: 

Using solar energy stored in your battery maximizes the amount of renewable energy your home uses! 

4. Potential electricity bill savings: 

If your utility requires time of use billing or doesn’t offer full retail net metering, you could save more on your electricity bill when you get a battery installed. 


Cons of solar batteries:

1. Upfront cost:

The cost of purchasing solar cells needs to be invested in the early stage. I would like to emphasize that MeritSun customizes a free shelf life of more than 10 years for each customer and provides the world's top after-sales service.

2. Take up space:

solar batteries are bigger than you think. You'll need somewhere to put all that storage---somewhere you don't mind seeing it! Fortunately, MeritSun's batteries can be stacked to suit your needs, battery appearance is generous; you can also place some small items on top of the battery, further saving space for your storage.

Are solar batteries worth it?

Although pairing solar panels with energy storage is becoming more common, it doesn’t mean it’s the right choice for everyone. Whether a battery is worth it depends on what you want it for.

If you want a source of backup power, a battery is worth considering, especially if you live somewhere that experiences frequent power outages. Storage batteries can store power during periods of high load and release it during periods of low load. Unlike a gas generator, you don't need fuel to fill up a battery, and they're incredibly quiet.

If you want to increase electricity bill savings, you'll need to look at your state and utility solar billing policies. You can see some savings if your utility requires time-of-use billing, but the additional savings could be minimal, depending on the rates.

In this regard, MeritSun has developed an efficient energy solution for you, which is our stacked series batteries.

Solar Battery FAQs

Q: What appliances can a solar a solar battery power?

A: The battery's power output rating determines what and how many appliances a battery can run. The power output is measured in kilowatts (kW). Most solar batteries have an output of at least 5 kW and can power a refrigerator, WiFi router, lights , outlets device chargers, and even an electric stove.


If you want to run something like a sump pump or an air conditioner, you may need to install more than one battery to reach the required power output. Having said that, our stacked range offers each battery pack with capacities ranging from 5-40 kWh, available in 5 kWh increments; and up to 15 kW continuous output.


Q: Can I install a battery without solar panels?

A: Yes! Batteries can be installed with or without solar panels, but they provide the most benefits when charged with solar. The best part is standalone batteries still qualify for the federal tax credit!


Q: What features should I look for in a solar battery?

A: The two most important things to look at are a battery's storage capacity and power output. These tell you what appliances a battery can run and for how long.
