Fort Mill Electricity Prices
Electricity costs in Fort Mill, SC have been rising steadily. Here’s what the data shows — and why it matters for homeowners.
South Carolina electricity rates climbed from 12.9 cents per kWh in 2021 to 14.1 cents per kWh in 2024 — a roughly 9.3% increase in just three years. Understanding this trend helps Fort Mill homeowners make informed energy decisions.
Solar installation in Fort Mill, SC gives homeowners a way to generate their own electricity. Rather than depending entirely on the grid, you produce power at home — which can reduce how much rising utility rates affect your monthly bill.
Solar panels typically last 25 years or more. Over that time, locking in a portion of your energy supply at a fixed cost can provide meaningful protection against the kind of steady rate increases South Carolina has seen in recent years.
Price of Energy: South Carolina vs National Average
Fort Mill Area Utility Providers
Fort Mill homeowners are served by Duke Energy, which charged 12.7¢ per kWh in 2023 — below both South Carolina’s state average of 13.70¢ and the national average of 16.0¢ per kWh that same year.
While Duke Energy’s current rate is relatively low, electricity prices have historically trended upward over time. That means what feels affordable today may cost noticeably more in five or ten years.
Solar can help Fort Mill homeowners lock in more predictable energy costs long-term. Even with lower-than-average rates today, reducing dependence on the grid is a practical way to plan ahead.

South Carolina Solar Incentives
Fort Mill homeowners have access to several solar incentives in South Carolina that can help reduce the upfront and long-term cost of going solar.
Available incentives include a 25% state tax credit, a full property tax exemption for systems up to 20 kW, and net metering credits. Additional rebates and loan programs depend on whether your home is served by Duke Energy Progress or Santee Cooper.
Note that the federal residential solar tax credit is no longer available. State and local incentives still apply. If you lease solar through Palmetto’s LightReach program, Palmetto claims the commercial tax credit and passes those savings to you through lower monthly payments.

South Carolina’s Solar Energy Tax Credit allows homeowners to claim 25% of their total solar installation cost as a credit against their state income tax liability. The credit is capped at $3,500 per year and can be carried forward for up to 10 years, with a lifetime maximum benefit of $35,000 — or 50% of your annual state tax liability, whichever is less. This makes it one of the most generous state-level solar incentives in the Southeast.
Eligible technologies include solar photovoltaic (PV) panels, solar water heaters, solar space heaters, and small hydroelectric systems. The system must be installed on a property located in South Carolina — either your primary residence or a business property. Because the credit is non-refundable, it can only offset taxes you actually owe; however, any unused portion rolls forward automatically each year.
To claim the credit, file Form TC-38 (SCH.TC-38) along with your South Carolina state income tax return. You’ll need to include supporting documentation such as your solar system design, permits, and receipts showing total installation costs. There is no expiration date on this credit, so it remains available for 2026 and beyond.
South Carolina law provides a full (100%) property tax exemption for solar energy systems installed on residential properties. This means that even though adding solar panels increases the market value of your home, that added value will not be included in your property’s assessed value for tax purposes — so your property tax bill stays the same after going solar.
The exemption applies to solar systems with a capacity of 20 kilowatts (kW) or less, and also covers advanced inverters and battery storage systems paired with solar. Both owned and leased solar systems are eligible, making this benefit accessible regardless of how you finance your installation.
This exemption is automatic and does not require a separate application in most cases, but homeowners in Fort Mill should confirm the process with their county assessor’s office. Combined with the state’s 25% solar tax credit, the property tax exemption helps make South Carolina a financially attractive state for going solar.
Duke Energy’s Shared Solar Program allows Duke Energy Progress residential and nonresidential customers in South Carolina to subscribe to solar energy generated at a community solar facility — no rooftop installation required. This program is open to all qualifying customers, including renters, those in multifamily housing, and customers who may not have a suitable roof for solar panels.
Subscribers receive a bill credit based on the energy output of their subscribed share of the community solar farm. For qualified low-income customers, Duke Energy Progress will waive the application cost and initial fees, a value of approximately $120, making the program even more accessible to those who need it most.
This is a practical alternative for Duke Energy customers in Fort Mill who want to benefit from solar energy without the complexity or cost of a rooftop system. Contact Duke Energy at 1-800-777-3600 or visit their website for current subscription availability, pricing, and eligibility requirements in South Carolina.
South Carolina’s net metering policy requires all investor-owned utilities with more than 100,000 customers to offer net metering to residential solar customers. Under net metering, any excess electricity your solar panels produce and send to the grid earns you a bill credit that can be applied to future months. Residential systems must be 20 kW or smaller to qualify, and enrollment in a time-of-use (TOU) rate plan is required by most utilities. The statewide program cap is set at 2% of each utility’s average peak demand over the prior five years.
Credit rates and policies vary by utility. Duke Energy ended 1:1 net metering in 2021 and now credits excess generation at reduced rates of approximately 2.6–4 cents per kWh. Electric cooperatives (e.g., York Electric) offer monthly netting with excess credits at reduced rates ranging from roughly 3.8–5.9 cents per kWh.
Because net metering credit rates in South Carolina are generally below the retail electricity rate — especially for Duke Energy customers — pairing your solar system with a battery storage system can be a smart financial move for residents of Fort Mill. Storing excess solar energy for use during peak hours allows you to avoid buying expensive grid electricity rather than selling it back at a discount. Always contact your specific utility before installing solar to confirm their current net metering terms, as policies can change.

Leasing Solar Panels
If you’d prefer not to pay the full cost of solar upfront, Palmetto offers an alternative through its LightReach program. Fort Mill homeowners served by Duke Energy Progress (DEP) or Duke Energy Carolina (DEC) — the primary utility providers in the area — are eligible for a Power Purchase Agreement (PPA) through LightReach.
With a solar PPA, you don’t own the system — Palmetto does. Instead of paying a large upfront cost, you simply pay for the electricity your panels produce at a set rate per kilowatt-hour (kWh). Because solar panels generate more power in summer than winter, your monthly PPA payment will naturally be a bit higher in summer and lower in winter. Over the course of a year, the average works out similarly to what a fixed monthly lease payment would be. You can compare buying vs. leasing solar to see which approach fits your situation best.
One of the biggest advantages of a PPA over a cash purchase is simplicity. With a cash purchase, you own the system — which means you’re also responsible for monitoring performance and coordinating any maintenance or repairs. With Palmetto’s LightReach PPA, Palmetto owns and maintains the system, including a 90% production guarantee and a comprehensive protection program. There’s no large upfront investment, no loan to manage, and no maintenance headaches. As soon as your panels are active, your savings start.
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!

Duke Energy Carolinas (DEC) and Duke Energy Progress (DEP) both offer monthly net metering, though 1:1 net metering ended in June 2021.
