Home Energy Rebates & Incentives —
What’s Actually Available Right Now

South Carolina’s state income tax credit covers 25% of the cost of a qualifying solar energy system — one of the strongest state solar incentives in the Southeast, and it has no expiration date.

• Claim up to $3,500 per year (or 50% of your SC tax liability)
• Unused credit carries forward up to 10 years — lifetime cap $35,000
• Also applies to solar water heating and certain geothermal equipment
• Filed with Form TC-38 on your SC return

Solar adds value to your home — but in South Carolina, residential systems up to 20 kW are exempt from property tax on that added value. Your system pays you back without raising your tax bill.

South Carolina’s income-based rebate programs for efficiency upgrades and electric appliances — including heat pumps and electrical work — are in development and expected to launch in 2026. Rebates are not yet available, and work completed before launch generally won’t qualify.

• HEAR: for households under 150% of Area Median Income
• Projects will require program-approved contractors

Duke Energy customers in SC earn credit for excess solar power sent to the grid. Rate structures are changing under the Solar Choice program, so how you’re credited depends on when and how you enroll — this is exactly the kind of detail we model for you before you sign anything.

Duke Energy and other SC utilities periodically offer rebates and financing support for high-efficiency heat pumps, smart thermostats, and weatherization. Offerings change by utility and season — as a Duke Energy Ally, we check what your specific utility offers before quoting your project.

North Carolina’s home energy rebate program is now available in all 100 counties. Rebates are based on household income and can cover up to 100% of project costs for qualifying households.

• 80–150% AMI: up to 50% of costs covered
• Work must be done by a program-registered contractor

Duke Energy’s incentive for new solar + battery installations in North Carolina is first-come, first-served — and capacity is nearly gone. Duke Energy Progress territory closed to new applications in late 2025; Duke Energy Carolinas territory has very limited remaining capacity.

• New solar + battery systems only, installed by a Duke Trade Ally
• Availability depends on your Duke territory and rate option
• Status changes weekly — contact us before assuming eligibility

Own a home battery in Duke territory? Enroll it in Duke’s Battery Control program (Power Manager / EnergyWise) and earn monthly bill credits — around $6.50 per kW — for letting Duke draw on your battery during peak demand. Open to existing and new battery owners.

North Carolina excludes 80% of the appraised value of a residential solar system from property tax — so most of the value solar adds to your home doesn’t show up on your tax bill.

NC solar customers choose between Duke’s Bridge Rate and time-of-use options for crediting excess solar production. The right choice depends on how your household uses power — we model both before you commit.
