South Carolina is one of the sunniest states in the Southeast. The Peach State gets about 4.5 to 5 peak sun hours per day on average. That makes it a great place for solar panels — even without a lot of state-level incentives.
The truth is, South Carolina's state programs are pretty thin compared to places like California or New York. But the federal tax credit is still huge, and South Carolina Power has made some progress on solar buy-back. Here is exactly what is on the table for South Carolina homeowners in 2026.
Top South Carolina Solar Incentives
🔑 Key Takeaways for South Carolina
Federal Tax Credit — 30%
The biggest incentive for South Carolinan solar owners.
No State Solar Tax Credit
South Carolina does not offer its own solar tax credit. Be honest with your budget.
South Carolina Power Net Metering Pilot
Available but limited — capacity caps apply.
8–13 Year Payback
Average break-even time for South Carolina homes.
30% Federal Tax Credit (ITC)
If your solar system costs $30,000, you get $9,000 back from the IRS. It's a dollar-for-dollar credit on your federal income taxes. This is the single biggest financial benefit for South Carolina solar buyers, and it is valid through 2032.
You can claim 30% of the total system cost — including panels, inverters, labor, and even battery storage if installed at the same time.
South Carolinans Should Know: No State Solar Tax Credit
Here is the honest truth — South Carolina does not have a state-level solar tax credit. This is unlike many other states that layer their own credit on top of the federal one. Some South Carolina lawmakers have pushed for solar tax incentives in the past, but as of 2026, nothing has passed into law.
The good news? The 30% federal ITC is still one of the largest solar incentives in the country — even without any state help.
South Carolina Power Net Metering Pilot
South Carolina Power runs a net metering pilot program that lets rooftop solar owners sell excess energy back to the grid. But it comes with a catch — the program has strict capacity caps and enrollment limits.
Even if you are accepted, compensation rates may be lower than the retail price of electricity. This is unlike states with full 1:1 net metering, where every watt you send to the grid gets credited at the same rate you buy power.
Bottom line: Ask your installer about South Carolina Power's current net metering policy before you sign any contract.
Property Tax Exemption for Solar — Varies by County
South Carolina has no statewide property tax exemption for solar installations. However, some individual counties have chosen to exempt the added home value from solar panels from property tax calculations.
This means the extra value your home gets from solar may not raise your property tax bill — but only in certain counties. Other counties will tax that added value like any other home improvement.
Check with your local county tax assessor to find out if your area offers an exemption.
South Carolina Power Renewable Energy Programs
Beyond net metering, South Carolina Power offers a few other programs that can help solar owners and green energy buyers:
- Community Solar: South Carolina has a community solar program. If your roof cannot handle solar panels, you can subscribe to a shared solar farm near you and get credits on your bill.
- Green Energy Program: South Carolina Power lets customers choose to pay a small premium to support renewable energy generation.
- Electric Vehicle Programs: South Carolina Power has made EV charging cheaper. Pair an EV with rooftop solar for maximum savings.
💡 Tip: Contact South Carolina Power directly or ask your solar installer about all current utility programs. Rates and eligibility change often.
How South Carolina Net Metering Comparest to Other States
If you have looked into solar in other states, you may hear a lot about net metering. Net metering is when your utility company buys back the extra electricity your panels produce, and gives you a credit on your bill.
In many states, net metering works at a 1:1 ratio. That means for every kilowatt-hour (kWh) you send to the grid, you get a credit for one kWh. South Carolina is not quite there yet.
South Carolina's net metering pilot program has limitations:
- The total program capacity is capped — once full, new applicants cannot join.
- Compensation rates may be based on avoided cost rather than retail electricity rates, which means you get paid less per kWh.
- Not all South Carolina utilities participate in the program.
This is one reason why battery storage is becoming more popular in South Carolina. If you cannot send excess power back to the grid at a good rate, it makes sense to store that energy in a battery and use it at night instead.
Solar Cost & Payback Period in South Carolina
So, what does a real solar system cost in South Carolina — and how long until it pays for itself?

Cost per watt
$28K–$35K

After federal tax credit
Based on a typical 10 kW residential solar system. Prices vary by installer, roof type, and location.
How Long Until Solar Pays for Itself in South Carolina?
Most South Carolina homeowners see a payback period of 7 to 10 years. Here is what drives that timeline:
- System size and cost: Bigger systems cost more but save more. Find the right balance.
- Electricity rates: South Carolina's average rate is around 12–14 cents per kWh. Higher rates = faster payback.
- Net metering participation: If you are in the South Carolina Power pilot program, your payback is shorter because you get credit for excess energy.
- Sun exposure: A south-facing roof with no shade will produce way more energy than a shaded or east-facing roof.
Solar panels last 25 to 30 years. So even on the longer end (13 years payback), you still get 12 to 17 years of essentially free electricity after that.
