South Carolina solar calculator

Live production from NLR (formerly NREL) PVWatts V8. South Carolina offers one of the strongest state solar credits in the US (TC-38, 25% of cost, $3,500/year with carryforward) plus a 100% property tax exemption. This calculator models the Dominion Energy SC residential 1:1 net-metering case — Duke Energy customers are different and not modeled here. Defaults: south-facing roof mount, 20° tilt, 14% losses.

Try (Charleston), (Columbia), (Mount Pleasant) — any valid US ZIP for this state also works.
