For homeowners in Suwanee, the value of rooftop solar in 2026 is driven by one key factor: using the power you generate yourself. With Georgia Power's current rules, electricity you send back to the grid is worth much less than the electricity you buy. This shifts the focus from exporting power to maximizing self-consumption, making system design and the role of battery storage more important than ever.

Estimated Solar Panel Costs in Suwanee (2026)
Without a federal tax credit available for systems installed in 2026, understanding the upfront investment is crucial. Here are the modeled costs for a typical Suwanee home:
- Solar Panel System (8.3 kW): The estimated gross cost is around $20,335. This system is sized to offset a significant portion of a home's electricity usage.
- Solar Panels + Battery (8.3 kW system with 10 kWh battery): The estimated combined cost is $35,335. The battery adds backup power and allows you to store solar energy for use at night.
These figures are based on an average cost per watt of $2.45 and serve as a reliable benchmark for budgeting in the Gwinnett County area.
Incentives & Tax Credits
Navigating Georgia's Solar Incentives in 2026
The financial landscape for solar has changed. The default federal tax credit for homeowners (the 25D credit) is not available for systems placed in service in 2026. Georgia also does not offer a state income tax credit for solar.
The primary financial benefits are now:
- Direct Bill Reduction: The most significant incentive is the money you save each month by not purchasing power from Georgia Power.
- Long-Term Rate Protection: Owning your power source helps protect your budget against future utility rate hikes.
- Potential Home Value: An owned solar system can be a compelling feature for potential home buyers, possibly enhancing your property's resale appeal.

Understanding Export Rates with Georgia Power
Georgia does not have a traditional 1-for-1 net metering policy. Under Georgia Power's Renewable and Non-Renewable (RNR) tariff, the electricity you export to the grid is credited at a much lower "avoided cost" rate—around $0.065 per kWh.
This is less than half of the retail rate you pay to buy electricity. Because of this gap, sending excess power to the grid provides limited financial benefit. The smartest strategy is to use as much of your own solar production as possible. A home battery is the most effective tool for this, storing your excess daytime energy so you can use it during the evening instead of selling it for a low price.
Projected Savings
How Solar Creates Value on Your Georgia Power Bill
Savings are generated primarily by avoiding Georgia Power's retail electricity rate of $0.14 per kWh. The more solar power you use directly in your home, the less you have to buy from the grid.
- A solar-only system is modeled to save a Suwanee homeowner approximately $1,157 annually, with a payback period of around 15.8 years.
- Adding a battery increases the annual savings to about $1,291. While the payback period extends to 19.9 years, the battery provides energy independence during outages and ensures you use your own cheap solar power instead of buying expensive grid power after sunset.
Over time, these savings can become more impactful if grid electricity costs continue to rise.
