South Carolina has good sun and has typically offered a state solar tax credit plus property tax relief, but net metering has been transitioning to newer rate designs, so verify your utility's current export terms on DSIRE. The estimates on this page combine the national cost of a typical residential system with South Carolina's local price level, so they reflect roughly what homeowners here pay in 2026 — but a real quote is the only way to know your number.
The single biggest incentive is the same everywhere: the federal Clean Energy Credit, worth 30% of your installed cost through 2032. On a $18,700 system in South Carolina, that is about $5,610 back at tax time. State and utility programs stack on top — and those are exactly the ones that change often, so we link you to the official, always-current database below rather than quoting figures that may be outdated.

How the 30% Federal Tax Credit Works
The federal Residential Clean Energy Credit gives you back 30% of your total installed solar cost as a credit against your federal income taxes — not a deduction, but a dollar-for-dollar reduction in what you owe. It covers panels, inverters, wiring, mounting hardware, labor, permitting, and even battery storage. For a $18,700 system in South Carolina, that is roughly $5,610.
The credit is non-refundable, but any unused portion can usually be carried forward to future tax years. You claim it with IRS Form 5695 for the year your system is placed in service. This is general information, not tax advice — confirm the details with a tax professional. Our solar tax credit guide walks through it step by step.
Net Metering in South Carolina
Net metering decides what your utility pays for the excess power your panels send back to the grid, and it has a huge effect on payback. South Carolina's posture in recent years is best summarized as net billing / reduced credit. These policies are among the most frequently revised in all of solar, and they often differ from one utility to the next, so treat this as a starting point and verify the exact buyback terms with your electric company.
