Buying solar panels in South Carolina
These pages give you the questions that make a solar salesperson uncomfortable, including questions that are awkward for us. A homeowner who understands price per watt, dealer fees and warranty structure gets a better system from whoever they choose.
It matters more in 2026 than it did, because there are companies still quoting on pre-2026 assumptions. Any quote applying a 30% federal credit is out of date by thousands of dollars.
Pick your town for the local version: which utility to verify, which rebate is or is not available there, and what the county requires before a system can energise.
By utility
Grouped by who bills you
Your utility decides more about a solar system than any equipment choice, so these are grouped that way rather than alphabetically. Territory can vary by address, which we confirm at the assessment.
