Fort Mill Electricity Prices
Electricity rates affect household budgets in Fort Mill, and recent statewide figures show why future energy costs are worth considering.
South Carolina’s average residential rate increased from 12.9¢ per kWh in 2021 to 14.1¢ in 2024. The national average rose from 13.7¢ to 16.5¢. These are statewide and national averages, not Fort Mill-specific rates.
A solar system can generate some of a home’s electricity on-site, reducing how much power it needs to buy from the utility. Actual bill impacts in Fort Mill depend on system size, energy use, and utility rules.
Over time, producing part of your own electricity may offer more predictability as utility prices change. Comparing installation costs, expected output, and applicable utility policies can help homeowners assess whether solar fits their long-term plans.
Price of Energy: South Carolina vs National Average
Fort Mill Area Utility Providers
In Fort Mill, Duke Energy is the utility provider represented in the available comparison. The latest figures provided are from 2023: Duke Energy’s electricity price was 12.7¢ per kilowatt-hour.
That 2023 rate was below South Carolina’s average of 13.70¢/kWh and the national average of 16.0¢/kWh. These figures show the comparison, but do not explain what drives differences among rates.
For Fort Mill households, solar can generate some electricity at home and may reduce how much power they draw from the grid. Its value depends on household energy use and system performance.

South Carolina Solar Incentives
Fort Mill residents may find state and utility programs that help offset solar costs; eligibility and availability vary. See solar incentives in South Carolina.
TC-38 gives qualifying owners a nonrefundable credit of 25% of eligible costs, subject to annual limits and a 10-year carryforward. Export credits vary by utility tariff.
Santee Cooper and Dominion community-solar offers have eligibility limits; Duke storage payments are for nonresidential customers. With LightReach, Palmetto manages the commercial ITC and passes savings through lower payments.
| Incentive | Type | Description | Source |
|---|---|---|---|
| South Carolina Solar Energy System Credit (TC-38) | State Income Tax Credit | South Carolina taxpayers who own and install a qualifying solar system may claim a nonrefundable credit of 25% of eligible costs, subject to annual limits and a 10-year carryforward. | Learn More |
| South Carolina Solar Choice and Utility-Specific Net Metering / Export Compensation | Net Metering / Net Billing | Solar customers may receive bill credits for exported electricity under utility-specific tariffs, but South Carolina does not provide one uniform statewide export-credit rate. | Learn More |
| Duke Energy PowerShare Storage (South Carolina nonresidential program) | Utility Battery Storage Demand Response Incentive | Participating South Carolina nonresidential customers with qualifying battery storage may receive enrollment, monthly capacity, renewable-charging, and curtailment-event payments. | Learn More |
South Carolina’s TC-38 credit is 25% of eligible solar system purchase and installation costs. The amount used in a tax year is limited to the lesser of $3,500 per facility or 50% of the taxpayer’s South Carolina income-tax liability; unused credit may be carried forward for up to 10 years. The credit is nonrefundable.
The taxpayer must own the qualifying system installed at a facility in South Carolina, so a renter or a customer whose system is leased generally cannot claim the credit. Eligible costs may include equipment and installation expenses. SCDOR guidance says a battery connected to a solar system and charged entirely by solar may qualify; a standalone or grid-charged battery does not qualify under that guidance. Claimants should review the current TC-38 instructions and retain invoices and system documentation.
South Carolina’s solar billing benefit depends on the electric utility, the customer’s tariff, and sometimes the date of the interconnection application. Investor-owned utilities use Solar Choice or other approved tariff options; credits for exported energy can depend on time of use, and fixed or non-bypassable charges may still apply. Older customers may have different transition or grandfathering terms.
Electric cooperatives and municipal utilities may set their own interconnection and export-credit rules, so their terms should not be assumed to match Duke Energy. Before signing an installation contract, homeowners should obtain the applicable tariff in writing and check export-credit values, monthly charges, annual or monthly true-up rules, and any battery-export limits.
Duke Energy’s PowerShare Storage program is for qualifying nonresidential customers in South Carolina; it is not a residential battery rebate. Published payment terms include a one-time $120 per enrolled kilowatt connectivity credit, an additional $30 per kilowatt when the battery is charged using renewable energy, $3.50 per enrolled kilowatt per month subject to a system-loss factor, and $0.10 per kilowatt-hour for energy used during curtailment events.
Participants allow Duke to dispatch enrolled storage during approximately 30–36 events per year, with each event lasting up to four hours. Businesses should confirm eligibility, enrollment availability, equipment requirements, and final payment calculations directly with Duke Energy.

How to Choose a Solar Installer in Fort Mill
Verify the license
South Carolina does not have one single solar-contractor license. The South Carolina Department of Labor, Licensing and Regulation (LLR), principally its Residential Builders Commission, oversees credentials for residential work. Electrical work requires a residential-builder specialty registration with an electrical classification or a residential-builder license. Roof-mounted systems also require the appropriate roofing specialty registration or a residential-builder license; added structural framing may require a carpenter classification. Ask which business and crew members will perform each part of the job, and verify credentials using South Carolina’s license guidance. Confirm that the credentials cover the actual work, not just sales or project management.
Look for certified installers
Ask whether the people designing and installing your system hold relevant North American Board of Certified Energy Practitioners (NABCEP) certifications; you can learn about certification at NABCEP. Certification can provide evidence of tested or documented solar training, but it is not a substitute for South Carolina credentials or a guarantee of workmanship. Ask what the specific certification covers and who on your project holds it. Manufacturer certifications may indicate that an installer has completed training or met a manufacturer’s requirements for particular equipment. They are useful context, not a reason to skip comparing the design, contract, warranties, and state licensing.
Compare quotes the same way
Request written proposals with matching assumptions. Compare:
- System size in kilowatts (kW), and price per watt; check that quotes include the same equipment and scope.
- Panel and inverter brands and models, plus the estimated production in kilowatt-hours per year (kWh/year) and the assumptions behind it.
- Warranty terms: panel product and performance, inverter, installer workmanship, and roof penetrations. Note who backs each warranty and how to make a claim.
- Who obtains permits and submits and follows up on utility interconnection.
- Total cost or monthly payment, what is included, and any payment escalator. Compare financing or lease terms, not only the initial payment.
Ask each installer to explain differences in production estimates or exclusions before comparing totals.
Permits, interconnection and your HOA
Building and electrical permits come from the local authority having jurisdiction, typically a city or county building-code office; requirements depend on the property. Ask which permits apply and who will obtain them. The homeowner or installer applies to the electric utility serving the property. Local providers include Dominion Energy South Carolina, Inc.; Duke Energy Carolinas, LLC; South Carolina Public Service Authority; and Duke Energy Progress – (NC). Confirm your provider and ask for the interconnection steps and who will manage them. South Carolina has no enacted statute preventing an HOA from banning or restricting residential rooftop solar; state guidance says HOAs may restrict panel placement. Review your HOA’s requirements before signing.
Red flags
- Pressure to sign the same day or a claim that a special offer cannot wait.
- Unlicensed crews, or an installer unwilling to identify who will do the work and show applicable credentials. An out-of-state crew is not automatically disqualified, but verify credentials for the South Carolina work.
- Vague production estimates with no explanation of assumptions, or large upfront deposits without clear written terms.
- Promises of federal homeowner tax credits for purchases in 2026; homeowner credits ended December 31, 2025.
Leasing Solar Panels
For Fort Mill homes served by Duke Energy Carolinas (DEC), a Palmetto LightReach power purchase agreement (PPA) is available. Availability depends on your utility, so check the provider listed on your bill.
With a PPA, you pay for the electricity the panels produce at an agreed price per kilowatt-hour, rather than a fixed monthly lease amount. Payments can vary seasonally as production changes. Learn more about buying or leasing solar.
A PPA can avoid paying the full system cost upfront. Palmetto owns the system and handles maintenance under the agreement, unlike a cash purchase where you own the equipment and are responsible for its upkeep. Explore LightReach details and agreement terms.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!

Yes. Fort Mill residents served by Duke Energy Carolinas have monthly net metering. Under the current tariff, solar exports offset electricity drawn from the grid one-to-one within the same time-of-use period during each billing month.
Any remaining excess is credited at a lower rate, roughly 2.7–4 cents per kWh, and rolls over month to month; there is no annual true-up. The tariff requires a time-of-use rate and includes a $30 minimum monthly bill. Check your utility bill to confirm your provider.
Yes. An owned (purchased) solar panel system may increase a Fort Mill home’s value. Zillow’s study found homes with solar panels sold for about 4.1% more, but this national finding is not a Fort Mill-specific valuation or a guarantee; system condition and the local market matter.
This potential increase applies to owned systems, not leased or third-party-owned (TPO) systems. With a lease or PPA, a buyer may need to assume the agreement, which can affect resale differently.
With Palmetto LightReach, Fort Mill homeowners can go solar with no upfront cost and a low fixed monthly payment. The calculator estimates $72/month for a small home, $93 for a medium home, and $117 for a large home.
A cash purchase is another option: the calculator estimates $17,436 after a modeled $3,500 South Carolina incentive for a medium system. Residential cash purchases no longer qualify for the federal 30% solar tax credit following the 2025 federal law change. See the calculator above for specific pricing.
With Palmetto’s LightReach solar lease, Palmetto owns the panels and you pay monthly to use the system. There’s no upfront cost; one payment includes the system, installation, monitoring, maintenance, and protection with a 90% Production Guarantee.
For a typical 7.38 kW Fort Mill system, the estimate is about $93/month, based on South Carolina’s 1,442 kWh/kW/year production ratio and a $0.105/kWh rate. The payment is typically below your current electricity bill, though utility charges may remain and savings vary with usage.
Solar can be worth it financially for Fort Mill homeowners. With LightReach, there’s no upfront investment, and the monthly lease payment is typically less than your current electricity bill, so savings can begin as soon as the system is active.
Your actual savings depend on your home’s energy use, solar production, and Duke Energy’s billing rules. You may still receive a utility bill for grid electricity or other charges.
A typical Fort Mill home system of about 7.4 kW may produce roughly 10,700 kWh per year, based on the article’s NREL PVWatts estimates for a 7 kW system.
Actual output varies with roof direction and pitch, shading, weather, and season. Fort Mill systems generally produce more electricity in summer and less in winter.
Yes. Solar panels work in Fort Mill, SC’s climate. South Carolina averages about 5.3 peak sun hours per day. Panels also produce electricity on cloudy days from available daylight, though output is lower than in direct sun.
Production changes with the seasons: longer summer days generally mean more output than shorter winter days. For example, the article’s Fort Mill estimate for a 10 kW system is about 45.9 kWh per day in July and 27.7 kWh per day in December.
