South Carolina is the #23 solar market nationally for residential solar installations. With approximately 210 MW of residential solar installed in 2024 and average AHJ review times of 9 business days at Charleston Building Inspections, getting your permit documentation right on the first submission directly impacts project profitability. The SC Distributed Energy Resource Program is the primary state-level financial incentive driving installer activity in South Carolina.
For South Carolina solar installers, permit turnaround time is a direct cost. Every business day a permit sits in AHJ review is a day the project cannot be installed — and 9 days is the average at Charleston Building Inspections. Jurisdictions that receive complete, AHJ-ready plan sets on first submission consistently process permits faster than the average. An incomplete first submission at Charleston Building Inspections can add another 9 days or more to your project timeline, pushing installation and PTO out by weeks.
Our South Carolina solar permit drawing service is purpose-built for this reality. Every plan set we produce for South Carolina projects is prepared to Charleston Building Inspections's specific checklist — not a generic national template. That means our South Carolina clients average first-pass approval rates well above the statewide average, and spend far less time chasing corrections, resubmitting paperwork, or explaining documentation to South Carolina reviewers.
