2026 Solar Installation Costs in Carrollton
After understanding the savings, the next step is looking at the investment. For a 9.2 kW system, which is a common size for homes in the area, the estimated upfront costs in 2026 are:
- Solar-Only System (9.2 kW): An estimated investment of $22,540. This system provides power during daylight hours. The payback period is projected at around 15.8 years.
- Solar + Battery System (9.2 kW with 10 kWh battery): This option, which includes energy storage for 24/7 solar power access and outage protection, is estimated at $37,540. The payback period is longer, at about 19.1 years, but it delivers higher annual savings and greater energy resilience.
Incentives & Tax Credits
Financial Incentives Available in 2026
For residential solar systems installed in 2026, the financial landscape is straightforward. The 30% federal tax credit that was available in previous years is no longer in effect for new homeowner systems. There are also no state income tax credits for solar in Georgia.
The entire financial case for solar in Carrollton now rests on its ability to generate long-term bill savings. The investment is weighed directly against the money saved by not buying power from the utility. This creates a clear, direct path to return on investment through energy cost avoidance.

How Georgia Power's Export Rules Affect Your Savings
Understanding how you are compensated for extra solar power is crucial in Georgia. There is no 1-to-1 net metering program. Instead, Georgia Power credits you for exported energy at a rate based on their 'avoided cost,' which is currently around $0.065 per kWh.
Since you pay about $0.14 per kWh for electricity you buy from them, the power you generate and use yourself is worth more than double the power you sell to the grid. This is why maximizing self-consumption—either by using power as it's generated or storing it in a battery—is the most effective strategy for savings in Carrollton.
Projected Savings
Potential Bill Savings with Solar in Carrollton
The primary benefit of installing solar panels is the direct reduction in your monthly electricity costs. By generating your own power, you purchase less from Georgia Power. Here’s what a typical 9.2 kW system could deliver:
- Estimated Annual Savings (Solar Only): A standard rooftop solar installation is modeled to save a Carrollton homeowner around $1,286 per year.
- Estimated Annual Savings (Solar + Battery): By adding a 10 kWh battery, you can store solar energy for nighttime use. This increases self-sufficiency and boosts the estimated annual savings to $1,462.
Beyond the monthly bill, an owned solar system can also be a useful long-term home-value feature, making your property more appealing to future buyers who are also concerned about rising utility costs.
