| 4 kW | $11,400 | $3,420 | $7,980 | 5,490 kWh | $714 | 11.2 years | $10,224 | $16,351 |
| 6 kW | $17,100 | $5,130 | $11,970 | 8,234 kWh | $1,070 | 11.2 years | $15,332 | $24,522 |
| 8 kW | $22,800 | $6,840 | $15,960 | 10,979 kWh | $1,427 | 11.2 years | $20,444 | $32,698 |
| 10 kW | $28,500 | $8,550 | $19,950 | 13,724 kWh | $1,784 | 11.2 years | $25,556 | $40,873 |
Solar Energy in Georgia: What You Need to Know
Georgia has good solar potential but limited state-level incentives. Georgia Power, the dominant utility, does not offer traditional net metering but has alternative programs for solar customers.
Electricity Rates in Georgia
The average residential electricity rate in Georgia is 13 cents per kWh, which is below the national average of approximately 16 cents per kWh. Lower electricity rates mean the payback period is longer, but the 25-year savings are still substantial. As electricity rates continue to rise (averaging 3% per year nationally), the value of solar ownership increases over time.
Peak Sun Hours and Solar Production
Georgia averages 4.7 peak sun hours per day, which is a solid level for residential solar. While not the sunniest state, the combination of decent sun hours with modern high-efficiency panels produces meaningful electricity savings throughout the year. A 6 kW system in Georgia produces approximately 8,234 kWh per year, accounting for standard system efficiency losses and typical weather patterns.
Georgia Solar Incentives and Programs
No state tax credit. No mandatory net metering. Georgia Power offers a solar buyback program at avoided cost rates. Some EMCs offer net metering voluntarily. Property tax exemption for solar systems.
Incentive Summary for Georgia
- Federal Tax Credit: 30% ITC (available through 2032)
- State Tax Credit: None
- Net Metering: Not mandated / Limited
- SRECs: Not available
- Avg. Installation Cost: $2.85/watt (before incentives)

Environmental Impact of Solar in Georgia
Installing a 6 kW solar system in Georgia offsets approximately 7,040 pounds of CO2 per year, which is equivalent to planting 58.1 trees annually. Over the 25-year lifespan of your solar system, that adds up to roughly 176,000 pounds of avoided carbon emissions. Choosing solar energy is one of the most impactful steps a homeowner can take to reduce their carbon footprint and contribute to cleaner air in Georgia communities.
