How Much Do Solar Batteries Cost?

The changing environmental landscape has prompted people to look into more sustainable and green options, with homeowners looking far and wide to find new ways of making wise investments.

One such investment can be in the form of solar panels! Given solar power is clean and renewable, solar panels produce electricity free of harmful emissions.

So, anyone with a solar panel system is bound to desire to get their hands on efficient solar batteries. This will allow the individual to store energy generated from the sun to utilize it later.

In simple terms, it gives you energy independence and saves you from massive electricity bills. So, pairing a solar battery with a solar panel gives way to a ‘hybrid solar system,’ which means you never have to worry about a power outage.

If you, too, seek to invest in solar panels but are unfamiliar with how solar batteries work and their cost, you have come to the right place! We have got all your answers for you. So, read on ahead.

Key Takeaways

• Solar batteries allow individuals to store excess energy generated by solar panels, providing energy independence and potential cost savings on electricity bills.
• The cost of solar battery storage systems can range from $200 to $15,000, depending on factors such as battery chemistry, manufacturer, and the number of batteries installed.
• Various factors impact the cost of solar batteries, including the type of battery, its capacity, installation labor, and available rebates and incentives. The average lifespan of a solar battery is 5-12 years.

Functioning of Solar Batteries

Solar panels work best during the daytime, especially at noon. This is also the hour when there is the least energy consumption.

On average, a solar panel system creates about 170 to 350 watts in one hour. Assuming a standard grid-tied solar panel system, all the excess solar energy returns to the utility grid. But, if you have a solar battery attached to your solar panel, every extra watt of energy is stored in the battery.

Subsequently, this battery-stored energy helps provide backup power when the sun goes down. This means you no longer have to rely heavily on electricity, and you are likely to save a lot of energy costs.

In short, day or night, rain or sunshine, your house will always be lit up if you invest in good solar battery storage!

The Cost of Solar Battery Storage Systems

A solar battery installation costs about $200 to $15000. This range of price relies on the battery chemistry. On the other hand, the solar panels for the residential grid that are usually coupled with lithium-ion batteries can cost about $7000 to $14000.

Additionally, other lead-acid batteries with small capacities are usually around $200. Although, these are not powerful enough to serve power throughout your house. You can use them as emergency backup power in RVs, sheds, etc.

Interestingly, the cost of solar batteries has dipped in recent years, but it still costs a decent amount. As such, people usually hesitate while investing in solar batteries. However, with the 30% federal solar tax credit and many other additional incentives, purchasing solar batteries is easy on the pocket.

Factors that Impact the Solar Battery Costs

The varying price fluctuations in different solar batteries are due to the following factors:

Manufacturer

As with everything else, a solar battery’s cost is highly determined by the brand manufacturing it. Different brands offer a range of varied features and services. Additionally, every brand has a peculiar manufacturing process. For example, Tesla Powerwall 2 costs just about $10,500. But Sonnen, a German manufacturer, offers a great line of luxury batteries worth $30,000 and beyond.

Battery System Chemistry

You can find an extensive range of batteries with differing internal chemistry in the market. In residential areas, lithium-ion batteries are among the most popular solar batteries. These batteries also have two specific chemistries involved.

One is the Nickel Manganese Cobalt (NMC), and the other is Lithium Iron Phosphate (LFP). NMC is more inexpensive than the LFP batteries and has been in the market for much longer. You can also find lithium polymer batteries that are pretty safe, handy, and secure for usage.

Other solar options that a homeowner generally leans towards are sealed lead-acid batteries. They are easy on the pocket but have little capacity. Additionally, they require consistent maintenance and have a short lifespan. On the other hand, a saltwater battery that uses sodium to conduct electricity makes the best of a liquid saltwater solution to capture, store, and disseminate the energy. They are also safe, last longer than 5000 cycles, are easily recyclable, need little maintenance, and are eco-friendly.

Lastly, there are deep-cycle batteries and solar gel batteries as well. The former solar energy system offers constant power over some time, while the latter is perfect for people who move around often. This is because they are rough and can handle a decent amount of traveling.

Number of Solar Batteries

This is pretty obvious. If you install multiple batteries, the energy storage system will be expensive. To figure out how many solar batteries are required for your solar panel to work aptly, be mindful of these factors:

1. The length of hours for which your appliances are actively used
2. The number of appliances requiring battery power
3. Number of kilowatt-hours utilized
4. The battery’s capacity

Generally, even after considering a power outage, the battery bank of one or two solar batteries is enough for everyday electrical work. There is also enough excess electricity to power up some necessary circuits.

Backup Load Panel

Solar batteries are only equipped to power key appliances in your house- from lights to the fridge. But, if you need to run heavy appliances, say an air conditioner, you would need additional batteries. One battery capacity does not have enough battery backup for the entire house. Hence, there might be a need to install a sub-panel.

Such a sub-panel, a backup load panel, or a critical load panel can cost installation charges of $1000-$2000.

Cost of Labor

A solar battery’s price differs from the labor required during installation. If the solar battery systems, aka the solar battery and panel, are installed simultaneously, the labor cost might be low. It’s because all the electrical work for both pieces of equipment can be done simultaneously.

But, if a solar battery is being installed to the existing system of the panel, there will be extra costs as additional electrical material would be required, and newer permits need to be filed.

Rebates, Incentives, and Benefits

Different areas have different solar battery incentives, which one can avail of at the time of solar battery system installation. For example, Oregon provides various solar battery programs that minimize upfront costs. On the other hand, California has come up with SGIP, a solar battery incentive program that pays for one-quarter of battery installation costs.

Additionally, an extra 30% is waived from the total battery installation cost if you pass for the federal solar tax credit. You should also check out the different incentives offered by your state.
