Cost & Incentives · Greenville, SC
Solar cost in Greenville,
without the 2025 sales pitch.
The federal homeowner tax credit ended. South Carolina still has a state credit. We quote after we see your roof and bill, not from a national average.
Why this page exists
Cost searches are noisy.
Greenville is specific.
If you search “solar cost Greenville SC,” you will often land on a marketplace article or a national brand page. Those pages are useful for a ballpark. They are not a quote for your house on Augusta Road, Woodruff Road, or a wooded lot in Taylors.
Detail Solar is a family-owned installer at 1609 Rutherford Road. We will not invent a price per watt on this page. We will tell you which incentives still exist in 2026, which ones do not, and where to start if you want a real number.
2026 incentives
What still helps,
and what does not.
Federal residential credit (ended)
The federal residential clean energy credit for homeowner-owned systems ended December 31, 2025. A 2026 home install should not be sold as if a 30 percent federal credit is still attached.
South Carolina state credit
S.C. Code Section 12-6-3587 still allows a 25 percent state income tax credit on qualifying solar costs, claimed on form TC-38. The amount you can use in one year cannot exceed $3,500 per facility or 50 percent of that year’s state income tax, whichever is less. Unused credit can carry forward up to 10 years. It is not refundable: if you owe no South Carolina income tax, it does not turn into a check.
Sales tax and property tax
Qualifying solar equipment can be exempt from state sales tax. An installed system is generally not supposed to raise your county property-tax assessment the way a kitchen remodel can. Confirm the property-tax piece with your county assessor for your parcel.
Not PowerPair
Duke Energy’s PowerPair program is for North Carolina. It is not a Greenville, SC rebate. We will not copy that claim.
How we quote
Your bill and roof,
not a lead form.
Most Greenville city homes are on Duke Energy. Some nearby addresses are on Laurens Electric or another co-op. Interconnection rules follow the utility on your bill. Shade, roof age, and whether you also need a detach for roof work change the number more than a national “average system size.”
If you already have panels and the question is a repair, that is a different page: home solar panel repair. If you want a new system, start with our Greenville installer page or residential installation.
Frequently Asked Questions
Cost questions,
plainly answered.
How much does solar cost in Greenville, SC in 2026?
There is no honest one-number answer. Cost depends on roof size, shade, equipment, and your Duke Energy or co-op bill. We quote after a free consult. Marketplace articles often cite national averages that do not match an Upstate roof.
Is the federal residential solar tax credit still available in 2026?
No. The federal residential credit for homeowner-owned systems (Section 25D) ended December 31, 2025. Do not budget a 30 percent federal credit on a new home system started in 2026.
What South Carolina solar incentives still apply?
South Carolina still has a state income tax credit equal to 25 percent of qualifying purchase and installation costs, claimed on form TC-38. In any year the credit cannot exceed $3,500 per facility or 50 percent of your state income tax liability, whichever is less. Unused amounts can carry forward up to 10 years. Qualifying solar equipment can also be exempt from state sales tax, and installed systems are generally not supposed to raise your property-tax assessment the way a remodel can. We confirm what applies on a consult; a tax professional files the forms.
Is Duke Energy PowerPair available in Greenville, SC?
No. PowerPair is a Duke Energy program in North Carolina. Greenville, SC Duke Energy customers should not expect that rebate. If another website implies otherwise, it is mixing up the Carolinas.
Should I use an online solar cost calculator?
A calculator can sketch a range. It cannot see your shade, roof age, or which utility you actually have. We would rather walk the property than sell you a number from a form.
