Florence Electricity Prices
Electricity prices shape household budgets in Florence, and South Carolina’s recent rate trend helps put solar’s potential role in perspective.
The chart’s statewide South Carolina average rose from 12.9 cents per kWh in 2021 to 14.1 cents in 2024, about 9%, while the U.S. average reached 16.5 cents. These are benchmarks, not Florence-specific rates.
For Florence homeowners, solar panels can generate electricity at home and reduce how much power they buy from the grid. The amount offset depends on system output, household use, and utility rules.
Over time, using solar may help limit exposure to rising grid prices, but it does not guarantee lower bills or eliminate utility charges. Long-term value depends on upfront cost, upkeep, production, and rate policies.
Price of Energy: South Carolina vs National Average
Florence Area Utility Providers
In Florence, SC, the latest available utility figures are from 2023: Duke Energy Progress averaged 14.7¢/kWh, Dominion Energy South Carolina 14.4¢/kWh, and Santee Cooper 11.4¢/kWh.
Duke Energy Progress and Dominion Energy South Carolina were above South Carolina’s 2023 average of 13.70¢/kWh, while Santee Cooper was below it. All three were below the 2023 national average of 16.0¢/kWh.
These figures compare prices but do not explain why rates differ among providers. Florence households can compare their electricity costs with a solar system’s potential production to consider whether it may offset some grid use; results vary.

South Carolina Solar Incentives
Florence residents may find state and utility programs that help offset solar costs. Explore the solar incentives in South Carolina below; eligibility varies by provider and program.
Options include South Carolina’s 25% income tax credit for qualifying system costs, utility-specific export bill credits, and programs from Santee Cooper, Dominion Energy South Carolina, and Duke Energy. Availability depends on utility, customer type, and program terms.
The 30% federal residential credit ended under the Big Beautiful Bill; state and local incentives remain. LightReach leasing has Palmetto handle the commercial ITC, passing 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 Florence
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 for residential work, requires credentials covering the work being performed. Electrical work requires a residential-builder specialty registration with an electrical classification or a residential-builder license. A roof-mounted system also requires the appropriate roofing specialty registration or a residential-builder license; added structural framing may require a carpenter classification. Ask the installer which credentials cover each part of your project, then verify them with the state. Review South Carolina’s licensing guidance.
Look for certified installers
Ask whether the people designing and installing your system hold relevant North American Board of Certified Energy Practitioners (NABCEP) certifications, and what work each credential covers. NABCEP certification is an additional qualification to consider; it does not replace any required South Carolina license. Ask about manufacturer certifications for the specific panels or inverters in your quote, too. They can indicate product-specific training or authorization, but compare the actual equipment, contract terms, and warranty support rather than treating a certification as a guarantee of quality. Learn about NABCEP.
Compare quotes the same way
Request written quotes with the same assumptions and check that each includes:
- System size in kilowatts (kW), total price, and price per watt.
- Panel and inverter brands and models, plus estimated annual production in kilowatt-hours (kWh/year).
- Warranty terms for panel product and performance, inverter, workmanship, and roof penetrations.
- Who obtains permits and submits the utility interconnection application.
- Total cost or monthly payment, the payment term, and any escalator that could change payments over time.
Ask installers to explain differences in production estimates and quote assumptions in writing. A lower monthly payment alone does not tell you which offer costs less overall.
Permits, interconnection and your HOA
Building and electrical permits are handled by the local authority having jurisdiction, typically a city or county building-code office; requirements depend on your property’s jurisdiction. The homeowner or installer applies for utility interconnection. Identify the provider serving your address from your electric bill. Providers in the supplied South Carolina list are Dominion Energy South Carolina, Inc; Duke Energy Carolinas, LLC; South Carolina Public Service Authority; and Duke Energy Progress – (NC). The applicable utility and requirements depend on the property and service provider.
South Carolina has no enacted statute preventing an HOA from banning or restricting residential rooftop solar; state solar guidance says HOAs may restrict panel placement. Check your HOA’s rules and approval process before signing or making assumptions about where panels can go.
Red flags
- Pressure to sign the same day or claims that an offer will disappear immediately.
- Unlicensed crews, or out-of-state crews whose South Carolina credentials and responsibility for the work are unclear.
- Vague production estimates, missing quote details, or reluctance to explain assumptions.
- A large upfront deposit without clear written terms for the work and payment schedule.
- Promises that a homeowner purchase made in 2026 qualifies for federal tax credits: homeowner credits ended December 31, 2025.
Leasing Solar Panels
In Florence, Palmetto’s LightReach Power Purchase Agreement (PPA) is available to eligible customers served by Duke Energy Progress or Dominion Energy South Carolina. LightReach is not available through Santee Cooper, so check your utility before comparing options.
With a PPA, you pay for the electricity the solar panels produce at an agreed price per kilowatt-hour, rather than a fixed monthly lease payment. Bills may vary with seasonal production. Learn more about buying or leasing solar and LightReach.
Unlike paying cash to own a system, a PPA generally avoids the upfront system purchase and the system owner is responsible for maintenance under the agreement. Review its payment terms, service coverage, and utility charges to understand your full costs.
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, but net metering in Florence, SC depends on your electric utility. Santee Cooper nets usage against exported electricity monthly, then credits any extra at 4.16¢/kWh in summer and 3.84¢/kWh in other months. Duke Energy Progress uses time-of-use billing: solar exports offset imports 1-to-1 within the same time period, while remaining excess earns a lower credit.
Dominion Energy South Carolina offers 1-to-1 time-of-use credits, with excess credits carried forward and settled each November. Check your utility bill and current tariff for the rules and charges that apply to your home.
Yes, an owned solar panel system may increase a home’s value in Florence, SC. Zillow’s study found homes with solar panels sold for approximately 4.1% more than comparable homes without them. This is a national estimate, not a guaranteed increase for every Florence property.
That potential value applies to systems the homeowner owns, not leased or third-party-owned (TPO) systems. A lease or PPA may affect resale differently because the buyer may need to assume the agreement.
In Florence, homeowners can go solar with a LightReach lease for a low fixed monthly payment and no upfront cost. The calculator estimates $93 per month for a typical 2,000–3,000-square-foot home; the actual payment depends on the system and agreement.
A cash purchase is another option: the calculator estimates $20,936 for a 7.38-kW system, or $17,436 after an estimated South Carolina incentive, if eligible. The federal 30% tax credit is no longer available for residential cash purchases following the 2025 federal law change. See the calculator above for other home sizes.
In Florence, a typical 7.38 kW solar lease is estimated at about $93 per month, based on South Carolina’s production ratio of 1,442 kWh per kW annually and a rate of $0.105/kWh. There is no upfront cost, and the monthly payment covers the system and installation.
With Palmetto’s LightReach lease, monitoring, maintenance, and a protection program with a 90% Production Guarantee are included. Payments are typically below the current electricity bill, so savings may begin when the system operates; actual costs and savings vary with usage and utility charges.
Yes. Solar panels work in Florence, SC, where sunny summers and long days support production. South Carolina averages about 5.3 peak sun hours per day, though a home’s roof exposure and shade affect its results.
Panels also generate electricity on cloudy days, but at a lower rate. Production typically rises in sunnier months and falls in winter, when Florence has shorter days and more weather-related variation.
Solar can be worth it financially in Florence, SC when the value of the electricity your panels produce outweighs your solar payments and any remaining utility charges. Savings depend on your roof, energy use, system output, and utility’s rules for solar power sent to the grid.
With a LightReach lease, there’s no upfront investment, and homeowners can start saving immediately because the monthly lease payment is typically less than their current electricity bill. Actual savings vary by home and bill.
