Incentives & Tax Credits

Financial Incentives for McDonough Homeowners in 2026

While the widely known federal tax credits for residential solar have ended for systems installed in 2026, the financial case for solar now centers on direct bill savings and long-term value. Georgia homeowners don't have a state-level income tax credit for solar, but the primary benefits are economic and practical:

  • Direct Bill Reduction: The most significant financial benefit is avoiding the purchase of electricity from Snapping Shoals Electric Membership Corporation, currently priced at $0.13 per kWh.
  • Increased Home Value: An owned solar system is an attractive feature for potential home buyers, potentially adding to your property's resale appeal without increasing your property taxes.
  • Energy Independence: A solar and battery system provides a buffer against grid outages, keeping essentials like refrigeration and lights running.

Understanding Export Rates with Snapping Shoals EMC

In Georgia, the rules for selling excess solar power back to the grid are critical. Snapping Shoals Electric Membership Corporation compensates homeowners for exported energy at an 'avoided cost' rate, which is significantly lower than the retail rate.

  • Retail Rate (what you pay): ~$0.13 per kWh
  • Export Rate (what you get paid): ~$0.06 per kWh

This difference is why maximizing self-consumption is key. Every kilowatt-hour of solar energy you use at home saves you $0.13. Every kilowatt-hour you export only earns you about $0.06. A battery helps you store that excess daytime energy so you can use it at night, saving you the full retail rate and making your system more valuable.

Projected Savings

Comparing Annual Savings: With and Without a Battery

Your savings depend on how much of your own solar power you use. A battery helps you use more of it, which is why it's recommended.

  • A 12.6 kW solar-only system is projected to save a McDonough homeowner around $1,607 annually, leading to a payback period of about 17.1 years.
  • Adding a 10 kWh battery increases the total annual savings to $1,887. While the initial cost is higher and the payback period extends to 18.6 years, this configuration provides more bill control and backup power during outages. The extra savings come from avoiding cheap grid exports and expensive evening grid purchases.

Over time, if grid electricity becomes more expensive, the value of producing and storing your own power will only increase.

Local Questions Answered

Why is a battery recommended in McDonough if it makes the payback period longer?
The recommendation is based on maximizing your monthly savings and gaining energy security. With export rates at just $0.06/kWh, sending power to the grid is not very profitable. A battery lets you store that power and use it later, saving you the full $0.13/kWh retail rate. It also provides valuable backup power during outages, a benefit not captured in simple payback math.
Are there any Georgia state tax credits for solar in 2026?
No, Georgia does not currently offer a state income tax credit for residential solar installations. The financial benefits come directly from reducing your electricity bill from Snapping Shoals Electric Membership Corporation and the long-term value added to your home.
