For homeowners in Roswell, a typical Georgia Power Co bill running around $156 a month is a constant reminder of grid dependency. With abundant sunshine, rooftop solar presents a clear opportunity to lower that cost. However, the financial outcome in 2026 depends entirely on understanding how to use the energy you generate, as Georgia's rules prioritize self-consumption over selling power back to the grid. An owned solar system is also a long-term asset that can improve a home's resale appeal.

Estimated Solar System Costs in Roswell (2026)
In early 2026, with the absence of a default federal tax credit for residential solar, the upfront cost is the primary number to consider. Below are modeled estimates for a typical Roswell home based on local energy needs.
- Solar-Only System (10.1 kW): The estimated gross cost is around $24,745. This system is sized to cover a significant portion of a home's electricity usage during daylight hours.
- Solar + Battery System (10.1 kW panels, 10 kWh battery): The estimated gross cost is approximately $39,745. This option includes energy storage to save your solar power for use at night or during an outage, which is key for maximizing savings with Georgia Power.
These figures are modeled estimates. The final price depends on equipment, roof complexity, and the installer chosen.
Incentives & Tax Credits
Georgia's Solar Incentives for 2026
As of 2026, the solar incentive landscape has shifted. The 30% federal income tax credit that many homeowners were accustomed to is not available for systems placed in service this year. This makes understanding Georgia-specific benefits even more important.
- Property Tax Exemption: This is a significant benefit in Georgia. The value added to your home by a rooftop solar system is 100% exempt from property taxes. You get the potential resale value boost without the higher tax bill.
- No State Income Tax Credit: Georgia does not offer a state-level tax credit for residential solar installations.
- Focus on Self-Consumption: The primary financial driver is avoiding Georgia Power's retail rate of over $0.14 per kWh. Every kilowatt-hour your panels produce and you use at home is a direct saving.

How Georgia Power Compensates for Your Extra Solar Power
Georgia does not have a traditional 1-for-1 net metering policy. Under Georgia Power's Renewable and Non-Renewable (RNR) tariff, the value of the electricity you send to the grid is much lower than the price of the electricity you buy.
- Retail Rate: You pay Georgia Power approximately $0.1418 per kWh for electricity you use from the grid.
- Export Rate: They credit you only about $0.0652 per kWh for any surplus solar energy you export.
This difference is why using your own solar power is so critical. A battery lets you store your valuable solar energy generated during the day and use it in the evening, instead of selling it to the grid for a low price and buying it back for more than double the cost just hours later.
Projected Savings
Projected Monthly & Annual Electricity Savings
Installing solar panels is about creating long-term value by reducing the amount of expensive electricity you need to buy from Georgia Power Co. If grid electricity rates continue to climb, the power your panels generate becomes more valuable each year.
- A solar-only system in Roswell is projected to save about $1,414 annually, with an estimated payback period of around 15.7 years.
- Pairing solar with a 10 kWh battery increases the potential annual savings to $1,632. While the initial cost is higher and the payback period extends to about 18.4 years, the battery allows you to store and use nearly all the solar energy you produce, providing greater bill reduction and backup power during outages.
