South CarolinaSolar Rebates — Utility, State & Local Programs

South Carolina solar rebates in 2026 come from the state, regulated utilities, and local programs. The federal residential credit does not apply to a system installed in 2026, so these programs do not stack with it.

State-Level Programs

South Carolina offers a 25% state income tax credit on installed solar costs, capped at $3,500. This is technically a tax credit, not a rebate — it reduces your state income tax liability rather than paying out cash up front. Carry-forward rules typically allow unused credit to apply in future tax years.

Utility Rebate Programs

The following utilities operate in South Carolina and may run rebate programs at any given time. Program availability is volatile — utilities open and close incentive windows multiple times per year, often without notice. Check directly with your utility before committing to an installation timeline.

How Rebates Stack

For a system installed in 2026 there is no federal residential credit to reduce, so a utility rebate does not change a federal credit basis. State income tax credits, where they exist, are claimed against state tax liability. Confirm the current rebate with the utility before you sign.
