- Solar costs and savings are estimates that depend on your system, energy use, utility rules, and eligibility for incentives.
Aiken Electricity Prices
Electricity prices have climbed in recent years, making the cost of powering an Aiken home worth a closer look.
South Carolina’s average residential electricity price rose from 12.9 cents per kWh in 2021 to 14.1 cents in 2024. These are statewide averages; rates in Aiken can vary by utility and plan.
A rooftop solar system can generate some of a household’s electricity, reducing the amount it needs to buy from the utility. How much it offsets depends on system output, household use, and local utility rules.
Over time, solar can help limit exposure to changing electricity prices by supplying power at home. Its long-term value depends on installation costs, system performance, and utility billing policies, so savings aren’t guaranteed.
Price of Energy: South Carolina vs National Average
Aiken Area Utility Providers
For Aiken-area residents served by Dominion Energy, the latest available comparison uses 2023 rates: electricity averaged 14.4¢ per kWh. 2024 figures are not yet available, so these numbers provide a snapshot rather than current pricing.
Dominion’s 2023 rate was above South Carolina’s 13.70¢/kWh average, but below the national average of 16.0¢/kWh. These comparisons show where the local rate stood; the figures alone don’t explain why prices differed.
For Aiken households, solar panels may provide a way to generate some electricity at home and reduce reliance on utility power. The effect on a bill depends on household usage and the solar system, so savings aren’t guaranteed.

South Carolina Solar Incentives
Aiken-area solar customers may find state and utility programs that help offset costs; availability depends on location and eligibility. See the solar incentives in South Carolina in the table below.
South Carolina’s TC-38 offers eligible system owners a nonrefundable tax credit. Utility export credits vary; Santee Cooper lists rooftop and Solar Share rebates, while qualifying Dominion customers may access community-solar bill credits.
Duke Energy’s storage payments apply to qualifying nonresidential customers. With LightReach leasing, Palmetto handles the commercial ITC and passes savings through lower monthly 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 |
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 or Dominion 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.

How to Choose a Solar Installer in Aiken
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 done. 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 each installer which credentials cover your project and who will perform each part of the work, then look up the credentials.
Look for certified installers
Ask whether the people designing and installing your system hold NABCEP certification, and check the certification information through NABCEP. You can also ask whether the installer has certifications from the manufacturers whose equipment it proposes. These are useful qualifications to compare, but ask for the exact credential and what it covers; they are not a substitute for the South Carolina credentials required for the work.
Compare quotes the same way
Request written quotes with the same assumptions so you can compare the system and the deal, not just the headline price. Ask each installer to explain any differences, including how its production estimate was calculated.
- System size: Compare the proposed size in kilowatts (kW) and estimated annual production in kilowatt-hours (kWh/year).
- Equipment: Record the panel and inverter brands and models.
- Price and payment: Compare total cost, price per watt, or monthly payment, as applicable. For a payment plan, ask whether there is an escalator and how it affects payments.
- Warranties: Compare panel product and performance coverage, inverter coverage, workmanship, and roof penetrations. Ask who handles a warranty issue.
- Project responsibilities: Confirm who handles permits and utility interconnection, and whether those costs are included.
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; the specific permits depend on your property’s jurisdiction. Ask the installer to identify the permits needed and who will obtain them. The homeowner or installer applies for interconnection with the electric utility serving the property. Local utilities include Dominion Energy South Carolina, Inc.; Duke Energy Carolinas, LLC; South Carolina Public Service Authority; and Duke Energy Progress – (NC). Confirm which serves your address and who submits the application. 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. Review your HOA requirements before signing.
Red flags
- Pressure to sign the same day: Take time to review the quote, contract, equipment, and responsibilities.
- Unlicensed or out-of-state crews: Ask who will do the work and verify the required credentials for it.
- Vague production estimates: Request a specific annual kWh estimate and an explanation of the assumptions.
- Large upfront deposits: Ask what the deposit covers and when remaining payments are due.
- Promises of federal tax credits for 2026 purchases: Homeowner credits ended December 31, 2025.
Leasing Solar Panels
In Aiken, Palmetto LightReach is available as a power purchase agreement (PPA) for eligible homes served by Dominion Energy South Carolina. Availability depends on your utility and address; other South Carolina utilities may not have LightReach. Check your utility bill to confirm service.
With a PPA, you pay for the electricity your panels produce at an agreed price per kilowatt-hour, rather than a fixed monthly lease amount. Payments can be higher in sunnier summer months and lower in winter. Learn more about buying versus leasing solar and LightReach.
Compared with paying cash, a PPA typically avoids the system’s upfront purchase cost. The system provider handles covered maintenance and repairs, while cash owners are responsible for arranging and paying for upkeep. Review agreement terms, including payment rates and service coverage, before deciding.
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, many Aiken homes have net metering or a similar solar export-credit arrangement, but the terms depend on the electric utility. For Dominion Energy South Carolina customers, the policy listed requires time-of-use Rate 5, which has a $14 monthly charge. Exported power offsets electricity used in the same on- or off-peak period.
Unused credits can carry forward, then are settled in November at a lower rate. Check your electric bill to confirm your provider and ask which solar tariff applies to your address.
Solar panels can increase a home’s value in Aiken, SC, when the homeowner owns the system. A Zillow study found homes with solar sold for about 4.1% more on average, but that national finding is not a guaranteed increase for every Aiken home. Value can depend on the system, roof condition, utility rules, and buyer demand.
This potential value benefit applies to purchased or otherwise owned panels, not leased or other third-party-owned (TPO) systems. A leased system or PPA may affect resale differently because the buyer may need to assume the agreement.
In Aiken, the LightReach option offers solar with no upfront cost and a low fixed monthly payment. The calculator estimates $72–$117 per month depending on home size; its medium-home example is $93 per month.
Cash purchase is another option. The calculator estimates $13,320–$22,105 after listed South Carolina incentives, with a medium-home estimate of $17,436. The federal 30% tax credit is no longer available for residential cash purchases following the 2025 federal law change. See the calculator above for estimates; actual costs vary by home and system.
Solar leasing lets Palmetto own the system while you pay for its electricity, with no upfront cost. In Aiken, LightReach is available to eligible Dominion Energy South Carolina homes; PPA payments can vary by season.
A typical 7.38 kW system is estimated at $93/month, based on South Carolina’s 1,442 kWh/kW/year production ratio and a $0.105/kWh rate. The payment includes the system, installation, monitoring, maintenance, protection, and a 90% production guarantee. Savings can start on day one if the payment is below your utility bill.
South Carolina’s nonrefundable TC-38 gives qualifying system owners 25% of eligible costs, capped at $3,500 per facility yearly or 50% of state tax liability, with unused credit carried forward 10 years. Utility export credits vary: Santee Cooper lists rooftop and Solar Share rebates; eligible Dominion customers may get community-solar bill credits. Duke storage payments are for qualifying nonresidential customers.
After the 2025 federal law change, the 30% residential credit is unavailable for cash purchases. With LightReach leasing, Palmetto claims the commercial ITC and passes savings through in lower payments.
In Aiken, a 7-kW solar system is estimated to produce about 10,200 kWh per year. The article’s typical 7.38-kW home system would produce roughly 10,800 kWh annually, based on the local NREL PVWatts estimates.
Output changes by season: a 7-kW system averages about 31 kWh per day in July and 20 kWh per day in December. Your home’s actual production depends on roof direction and pitch, shade, weather, and system conditions.
