Solar battery installation in Myrtle Beach, SC
Why this changed in 2026 · as of July 2026
In Myrtle Beach, Santee Cooper credits exported solar at about 4.16¢ per kWh in summer and 3.84¢ outside summer while retail power costs about 11.4¢ per kWh. That means a kilowatt-hour you store and use yourself is worth roughly three to five times one you export. Storage in Myrtle Beach is now an economic decision as much as an outage-protection one.
Local storage case
Why storage does or does not fit in Myrtle Beach
Myrtle Beach has direct hurricane exposure and mandatory evacuation zones, so extended outages are a genuine planning case rather than a remote one. The realistic design scenario is a property without power for several days, possibly unoccupied for part of it, with return delayed by evacuation orders. Sizing for essentials with solar recharging the battery daily is what makes that survivable without an unreasonably large system.
For rental properties the calculation is commercial rather than domestic. An outage during a booked week means lost revenue and refunds, which puts a value on resilience that a private residence does not have. That frequently justifies a larger critical-load list than a homeowner would choose, covering guest comfort rather than just preservation of the property.
The economics need care here, because Santee Cooper's retail rate is around 11.4 cents, the lowest we work with, so the value of shifting a kilowatt-hour from midday to evening is smaller than in Dominion or Duke territory. Storage in Myrtle Beach is therefore easier to justify on resilience than on arbitrage, and we would rather say so than build a savings case that the local rate does not support. Horry Electric Cooperative serves many surrounding addresses on different terms again.
Written for Myrtle Beach 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
Santee Cooper does not credit exports one-for-one: exported power earns about 4.16¢ per kWh in summer and 3.84¢ outside summer. Sending surplus power to the grid is no longer almost as good as using it, which is what changes the case for a battery in Myrtle Beach.
You still buy power at about 11.4¢ per kWh. The gap between that and what an export earns 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 Santee Cooper's net metering and rebate programme rate structure rewards. Backing up essentials well beats undersizing a whole-house dream, and it costs less.
- 02
Permits, Santee Cooper interconnection and HOA
Horry 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 Myrtle Beach
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 Myrtle Beach 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.
Myrtle Beach specifics
What storage involves here
Coastal Myrtle Beach adds real constraints. Getting these right is most of the job.
- 01
A separate electrical permit
Horry 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
Direct hurricane exposure and mandatory evacuation zones. Extended outages are a genuine planning case here, and for rental properties an outage during a booked week has a direct cost.
- 03
Where the battery goes
Placement matters for heat, flood exposure and corrosion. Garage-interior siting is usually the right answer here.
- 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.
Permits and approvals
What approval takes in Myrtle Beach
This is the part most quotes leave vague, and it is the part that decides how long a job takes. Below is what a system at a Myrtle Beach address actually has to clear. We handle all of it, and you file none of it yourself, but you should know what you are agreeing to a timeline for.
- 01A building permit and a separate electrical permit for a rooftop system
- 02Standard plan review for systems of roughly 10 kW and above
- 03A zoning review as well for any ground-mounted array
- 04An additional electrical permit where battery storage is included
- 05Structural review, roof-access pathways and setbacks under high-wind coastal requirements
- 06A NABCEP-certified crew and Trade Ally participation if the Santee Cooper rebate is being claimed
- 07Utility interconnection approval before the system is allowed to energise
Rebate:Santee Cooper runs a rebate of $950 per kW up to $5,700, which requires a NABCEP-certified crew and Trade Ally participation, is capped at 6 kW-AC over the lifetime of a meter, and is funded annually with a first-come waitlist. It is real money and it materially changes the numbers, but it is rationed, so we confirm current-year availability for your address before it forms part of any figure we give you.
Requirements are read from the authority that reviews your address, not assumed from the county. In SC that distinction is routinely the difference between a permit issued and a permit returned.

Myrtle Beach battery FAQ
Battery questions from Myrtle Beach homeowners
Is a home battery worth it in Myrtle Beach in 2026?
The economics improved when net metering changed. Santee Cooper credits exported power at about 4.16¢ per kWh in summer and 3.84¢ outside summer while you buy power at about 11.4¢ 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 Myrtle Beach 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 Myrtle Beach?
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 Horry County?
Yes. Battery storage requires an additional electrical permit alongside the permits for the solar system itself in Horry 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.
