What to know in South Carolina.
South Carolina’s net-energy-metering law defines eligible customer-generation and requires applicable safety, performance, interconnection and reliability standards.
The State Energy Office directs interconnection and insurance questions to the utility and installer.
Do not assume one utility’s solar tariff applies statewide. The Building Codes Council directs project-specific code interpretations to the local building official; confirm the effective code cycle for your permit date.

Narrow possible delivery utilities by ZIP or confirm yours
Find the delivery utility on your electric bill first. A retail supplier or on-site solar seller may be a different company; your delivery utility handles the local grid connection.
ORS explains its electric utility role; municipal systems and cooperatives have different regulatory scope. Confirm the serving provider for the address.

Official logo sources · Initials indicate a logo not yet verified. Municipal-owner emblems identify the owning city or village.
Source: EIA-861 final 2025 detailed data · Reporting year 2025. Names and reported counties are historical survey data, not a live address lookup. A county can have several providers, and a listing does not mean every resident can choose it. Small/territory-only reports may not identify residential service separately.
Credits, rebates, and other opportunities.
Check the program’s scope before comparing savings: a tax exemption, equipment rebate, loan and electricity-export payment provide different benefits. Funding, utility territory, income, equipment and installation dates can limit eligibility. Amounts below are not added together or deducted from product prices.

South Carolina Solar Energy Credit
South Carolina Department of Revenue · Solar
A qualifying taxpayer-owned solar system may qualify for the state’s nonrefundable income-tax credit.
- Benefit
- 25% of eligible purchase and installation costs; annual use is limited to the lesser of $3,500 per facility or 50% of state tax liability.
- Who may qualify
- Qualifying equipment installed in or on a South Carolina facility owned by the taxpayer; certification/licensing and state tax-liability rules apply.
- Before applying or buying
- Review DOR’s ruling and filing instructions before purchase and claim. Rebates may affect eligible costs; unused credit and carryforward are subject to the state rules.
No matching records in this reviewed selection. Check the official program sources for more options.
Selected official opportunities, not a complete inventory. Eligibility, participating utilities, available funds and application timing must be confirmed for the service address. This is a curated starting list, not every local incentive or a guarantee of available funding.
Federal programs in every state
The federal rules below apply nationally. State-administered federal rebates still require the local program to be operating and your project to meet its conditions.
Residential Clean Energy Credit (25D)
Closed / endedNot available for new property placed in service after December 31, 2025. Do not assume a federal 30% credit for a new 2026 solar, wind, geothermal or battery installation.
IRS: Residential Clean Energy CreditEnergy Efficient Home Improvement Credit (25C)
Closed / endedThe federal home-efficiency credit, including qualifying heat-pump improvements, ended for property placed in service after December 31, 2025.
IRS: Energy Efficient Home Improvement CreditHOMES / High-Efficiency Electric Home Rebates
Eligibility / funding conditionsFederally funded home-energy rebates operate through participating local administrators. Check the state program’s launch, current funding, eligible measures and application requirements. This is not a blanket rooftop-solar rebate.
DOE: Home Energy Rebates ProgramWeatherization Assistance Program
Eligibility / funding conditionsIncome-eligible households may receive approved home-weatherization services through local agencies. This is assistance delivered through a program, rather than an automatic reimbursement for equipment you buy.

Permits and electrical codes.
Confirm the adopted electrical, building and fire code editions and amendments with the authority issuing the permit. A utility approval does not replace construction permits or inspections.
Use the adoption authority linked below to check the effective date and amendments. The newest published NEC edition is not automatically the edition adopted for your project.
Before ordering equipment.
Two conversations. Keep their answers separate.
Track permits and interconnection in a project
- Confirm the permit authority
Ask the city, county, or state electrical office which building, electrical and fire-code editions and amendments apply to this address. Request the solar/ESS permit checklist and inspection sequence.
- Confirm the utility process
Give the serving utility your proposed capacity, inverter model and operating mode. Ask which interconnection application, tariff, export limits, meter changes and written operating authorization apply.
- Document the exact equipment
Collect model-specific certificates, installation manuals, a one-line diagram, site/roof plans, and the battery/inverter pairing if storage is proposed. Check them with the permit authority and utility before ordering.
For the general permitting and inspection process: DOE: Permitting and Inspection for Rooftop Solar .
UL, NEMA, and system acceptance.
Different evidence, different scope.
Check the exact model and approved system configuration. A UL 1973 battery listing or UL 9540A fire-test report does not, by itself, establish UL 9540 certification of a complete storage system.
Open the UL & NEMA referenceScope and system-level certification: UL Solutions: Energy Storage System Testing and Certification .
