Do Solar Panels Increase Home Value in South Carolina?
Yes. Homes with owned solar panels sell for roughly 4–6% more than comparable homes without them, according to national studies. In South Carolina there's a bonus: the state gives a 100% property tax exemption on the value solar adds, so your home is worth more but your property tax bill doesn't go up. Leased systems are the main exception.
Buyers increasingly see a solar home as one that comes with a paid-off utility bill — and in a state where Duke and Dominion rates keep climbing, that's a real selling point. Two questions usually sit underneath "does solar add value?": how much value does it actually add, and does it raise my property taxes. Here's the straight answer for South Carolina.
How much value do solar panels add?
National studies from Zillow and Lawrence Berkeley National Lab put the resale premium at roughly 4–6% for homes with owned solar, and those homes tend to sell faster because the buyer inherits lower power bills. Treat it as a range, not a guarantee — the actual number depends on system size, system age, and your local market.
| Home value | ~4% premium | ~6% premium |
|---|---|---|
| $300,000 | +$12,000 | +$18,000 |
| $400,000 | +$16,000 | +$24,000 |
| $500,000 | +$20,000 | +$30,000 |
These are illustrative ranges from national resale studies, not an appraisal. A local agent and appraiser set your actual number.
Will solar raise my property taxes in South Carolina?
No. South Carolina offers a 100% property tax exemption on the added value from residential solar systems 20 kW or smaller, including battery storage and advanced inverters. So the value bump doesn't increase your assessed value or your tax bill. The exemption is usually applied automatically at permitting and interconnection, but some county assessors ask for documentation — keep your install paperwork.
Owned vs. leased — this is the part that matters at resale
An owned or paid-off system adds value cleanly. A leased system or PPA can complicate a sale because the buyer has to assume the lease — and some buyers walk rather than take on someone else's contract. If resale value is a goal, buying (cash or loan in your name) beats leasing.
Does solar help a home sell faster in SC?
Generally yes, when the system is owned. A transferable, paid-down energy cost is an easy selling point — especially as SC utility rates keep rising. Pair the listing with production history, warranties, and inverter/monitoring info so the buyer's agent has everything ready.
The bottom line for SC homeowners
Owned solar generally adds resale value, sells faster, and in South Carolina isn't taxed on the bump — a rare combination. Whether it pays off for your specific home still depends on your roof, your bill, and how long you plan to stay.
