Solar calculator for Georgia
Panels, system size, cost and payback for Georgia, from your own power bill.
The average Georgia home uses 1,074 kWh a month and pays 14.1 cents per kWh, which puts Georgia at mid-range electricity prices, so payback depends mostly on how much sun your roof gets. Summer cooling drives the bill in Georgia, and that load lands in the sunniest hours, which suits solar. A south-facing fixed array there makes about 1,420 kWh per installed kW a year, and the worst winter month still gets 3.45 peak sun hours a day. Drop in your own bill below and the numbers on this page are replaced by yours.
A worked example for Georgia
Take the average home: 1,074 kWh a month, which is 12,888 kWh a year, at 14.1 cents per kWh (EIA, 2024 residential averages, as of 2026-11). Sized to cover all of that use, the tool returns 9.1 kWdc and 23 panels, needing about 483 square feet of roof. The installed estimate is $22,599 (national median, EnergySage H2 2025), yearly savings are about $1,817, and simple payback is 12.4 years, with no incentive applied.
Sun and yield in Georgia
We use 1,420 kWh per installed kW per year for Georgia, from NREL PVWatts v8 for the state's largest city at a 20 degree south-facing tilt (via TheGreenWatt, as of 2026-11). The darkest month averages 3.45 peak sun hours a day, which matters if you plan to go off-grid or size a battery. A different roof angle or heavy shade changes this, so treat it as a starting point.
Incentives
The 30% federal tax credit ended for homeowner purchases after December 31, 2025, so none is applied here. See the tax credit guide. Look up Georgia and your own utility for net metering terms and any local programs before relying on a payback number.
