For homeowners in Alpharetta, a typical monthly electric bill runs around $142. As utility rates change over time, many are looking for ways to control this recurring cost. Rooftop solar offers a direct path to generating your own power, but the financial outcome in Georgia depends heavily on how you use that energy, especially under Georgia Power's compensation rules. Understanding the system costs and how export rates work is the first step to seeing if solar is the right fit for your home.

Estimated Solar System Costs in Alpharetta (2026)
The cost of a solar installation is based on its size, equipment, and whether you include battery storage. Based on local electricity usage, here are two modeled scenarios for an Alpharetta home:
- Solar-Only System (9.2 kW): The estimated gross cost is around $22,540. This system is sized to offset a significant portion of a typical household's electricity consumption.
- Solar + Battery System (9.2 kW panels, 10 kWh battery): Adding a home battery for energy storage and backup power increases the estimated total cost to $37,540.
These prices reflect the full installation cost before any savings are applied. An owned solar system can also be a significant long-term feature, potentially improving your home's resale appeal to future buyers.
Incentives & Tax Credits
Georgia's Solar Incentives for 2026
Georgia's incentive landscape is different from many other states. The primary financial benefits come from bill savings rather than tax credits.
- Federal & State Tax Credits: As of early 2026, there is no federal residential solar tax credit available for new systems. Georgia also does not offer a statewide income tax credit for solar installations.
- Focus on Self-Consumption: The main financial driver is using the solar energy you produce to avoid buying it from Georgia Power. Because exported power is credited at a low rate, the more solar you use at home, the more you save. A battery is the most effective tool for maximizing this self-consumption.

Avoided-Cost Compensation

Understanding Exported Power with Georgia Power
In Alpharetta, your utility is Georgia Power, which uses a compensation structure often called 'net billing' or an 'avoided cost' rate. This is a critical detail for understanding solar economics.
When your panels produce more electricity than your home is using, the excess power is sent to the grid. Georgia Power credits you for this exported energy at a rate of approximately $0.065 per kWh. This is significantly lower than the retail rate of about $0.14 per kWh that you pay for electricity you buy from them.
This rate difference is why a battery is recommended. Storing your excess solar energy in a battery for use in the evening is more valuable than exporting it for a low credit. It allows you to offset power you would have otherwise purchased at the full retail price, increasing your total savings and providing backup during outages.
Projected Savings
How Much Can You Save on Your Georgia Power Bill?
Installing solar panels creates savings by replacing the expensive electricity you would normally buy from the grid. The value of those savings changes depending on whether you add a battery.
- With a 9.2 kW solar-only system, you could see an estimated $1,286 in electricity bill savings in the first year. The simple payback period is modeled at around 15.8 years.
- Adding a 10 kWh battery increases the first-year savings to an estimated $1,462. The battery helps you use more of your own solar power on-site, but its higher initial cost extends the modeled payback period to 19.1 years.
These savings can become more valuable over time. If grid electricity from Georgia Power becomes more expensive in the future, the power your system generates will offset those higher costs, increasing your return on investment.
