Before you buy in South Carolina

This page is informational research, not legal advice — and it can fall out of date quickly. Before installing anything, confirm the current law and its start date, any size limit, your local building and fire codes, your utility’s requirements, that the kit is certified as a complete system, your landlord or homeowners association (HOA) rules, a safe way to mount it, and the maker’s instructions.

Estimate your savings in South Carolina

Use the calculator to get a rough idea. For a truer number, swap the national average electricity price for your own rate (it’s on your bill), and remember that surplus power you send back may earn nothing unless your state and utility specifically pay for it.

Estimated monthly savings$12
Electricity made per year794 kWh
Time to pay off8.0 years

A planning estimate, not a promise. It doesn’t check whether plug-in solar is legal where you live, whether a kit is certified, whether your outlet or mount is suitable, or whether your utility pays for surplus power.
