Solar battery installation in North Augusta, SC
Why this changed in 2026 · as of July 2026
In North Augusta, Dominion Energy South Carolina credits exported solar at roughly 2.8–4.1¢ per kWh while retail power costs about 14.4¢ per kWh. That means a kilowatt-hour you store and use yourself is worth roughly three to five times one you export. Storage in North Augusta is now an economic decision as much as an outage-protection one.
Local storage case
Why storage does or does not fit in North Augusta
Storage in North Augusta is a self-consumption argument first. On a Dominion Energy South Carolina meter, exported power earns roughly 2.8 to 4.1 cents against a retail rate near 14.4 cents, so holding afternoon production for the evening captures several times what exporting it pays. That is arithmetic, and it stands whether or not you are worried about outages.
On an Aiken Electric Cooperative address the same logic applies but against the cooperative’s own numbers, which it sets under its distributed-generation rider rather than under a Commission tariff. We read the current schedule before advising, because the gap between retail and export is exactly what a battery monetises and the wrong gap gives a confident answer that is wrong.
On resilience we would rather be modest than sell the bigger number. Summer thunderstorm outages happen across the CSRA, and we size for essentials over a couple of days: refrigeration, lighting, internet, a well pump where there is one. Running central air through a multi-day outage is a much larger and more expensive system than most people have in mind when they ask for whole-house backup.
Written for North Augusta specifically. Your own roof, bill and meter still decide the answer, which is what the free assessment settles.
The maths changed
Storing a kilowatt-hour now beats exporting one
Until the end of 2025, Dominion Energy South Carolina credited exported solar close to one-for-one. Sending surplus power to the grid was almost as good as using it, so a battery in North Augusta was mostly about riding out storm-season outages.
That ended on December 31, 2025. Under Solar Choice, exports credit at roughly 2.8–4.1¢ per kWh on a time-of-use basis, with a rider of about $14 a month and a November true-up at avoided cost. You still buy power at about 14.4¢ per kWh. The gap between those two numbers is the entire case for storage.
A battery closes that gap. Instead of exporting afternoon surplus for a few cents and buying evening power back at full retail, you store the surplus and spend it yourself. For a household that is out during the day and home in the evening, this is the difference between a system that barely moves the bill and one that does what you expected.
We are not going to promise you a figure for that, because it depends on your usage shape and your rate. What we will do at the assessment is model your actual load profile against your actual rate and show you whether storage earns its cost at your address.

We handle everything
From critical-load mapping to switched-on
- 01
Critical-load mapping, not box-selling
We start from what you actually need running in an outage and what your Solar Choice rate structure rewards. Backing up essentials well beats undersizing a whole-house dream, and it costs less.
- 02
Permits, Dominion Energy South Carolina interconnection and HOA
Aiken County (city limits extend into Edgefield County) requires a separate electrical permit for storage on top of the solar permits. We pull all of it, file the interconnection, and prepare the architectural-review packet where a board or HOA is involved.
- 03
Installation and critical-loads panel
Our crews install the battery and tie it to a critical-loads subpanel with automatic switchover, so backup engages the moment the grid drops. No manual steps, no extension cords.
- 04
Commissioning and monitoring
We commission the system, walk you through the app so you can see state of charge and what is protected, and stay reachable long after activation.
Every battery install carries our lifetime full-system and roof-penetration warranty, on top of the manufacturer's battery warranty.
Honest numbers
What drives battery cost in North Augusta
There is no honest fixed price for a battery. These are the real drivers, and a free assessment turns them into a figure for your home.
Usable capacity
How many kilowatt-hours you want available, and whether you stack more than one unit. This is the largest single factor.
Electrical work
Adding a critical-loads subpanel, and any service-panel upgrade your home needs first. Common on older North Augusta properties.
Retrofit or new build
Pairing storage with a new system is cleaner than retrofitting to an existing inverter that was never specified for it.
North Augusta specifics
What storage involves here
North Augusta has its own constraints. Getting these right is most of the job.
- 01
A separate electrical permit
Aiken County (city limits extend into Edgefield County) requires one for storage on top of the solar permits, with its own inspection. We pull it and meet it.
- 02
Your outage profile
CSRA summers run hot and long, so cooling load peaks in the same hours a roof produces hardest. Summer thunderstorm outages do occur.
- 03
Where the battery goes
Placement matters mostly for heat. Batteries dislike an unconditioned attic or a west-facing wall in a Midlands summer, so garage-interior siting is usually right.
- 04
Service panel capacity
Older services often need attention before storage can be added cleanly. We run the load calculation before quoting, not after.
- 05
Battery or generator?
For very long outages a standby generator can be the better answer, and we will say so if it is. Compare the two.
- 06
Retrofit or new build
Pairing storage with a new system is cleaner than retrofitting to an inverter that was never specified for it. We check yours first.
North Augusta battery FAQ
Battery questions from North Augusta homeowners
Is a home battery worth it in North Augusta in 2026?
The economics improved when net metering changed. Dominion Energy South Carolina credits exported power at roughly 2.8–4.1¢ per kWh while you buy power at about 14.4¢ per kWh, so a kilowatt-hour you store and use yourself is worth roughly three to five times one you export. That is a stronger case than under the old one-for-one net metering, on top of the outage protection.
How long will a battery run my house during a North Augusta outage?
It depends on usable capacity and what you back up. Most homeowners back up essentials, refrigerator, lights, Wi-Fi, well pump, medical equipment, a few outlets, which stretches runtime far longer than trying to run central air. During your assessment we map your critical loads so you know realistically what to expect rather than a marketing number.
Can I add a battery to solar I already have in North Augusta?
Usually yes. Many existing systems can be retrofitted with a battery and a critical-loads panel. We check your current inverter, panel capacity and interconnection status first, and tell you honestly whether it is a clean add-on or needs additional equipment.
Do I need solar to get a battery?
No. A battery can be installed on its own to back up your home from the grid, though pairing it with solar lets you recharge from your own panels instead of only from the utility. We will walk through both options based on your goals.
Does battery storage need a separate permit in Aiken County (city limits extend into Edgefield County)?
Yes. Battery storage requires an additional electrical permit alongside the permits for the solar system itself in Aiken County (city limits extend into Edgefield County), and the installation must satisfy the National Electrical Code as adopted in South Carolina. We pull the permits and handle the inspection sequence as part of the project.
Does a battery qualify for South Carolina’s 25% state tax credit?
Battery storage paired with solar may qualify for South Carolina’s 25% state tax credit, subject to the same annual cap and eligibility rules as the rest of the system. The expired federal credit no longer applies. Confirm your own position with a tax professional.
