The financial case for solar is built on strong incentives. All Mableton homeowners are eligible for:

  • The 30% Federal Solar Tax Credit: A direct credit, not a deduction, that reduces your federal tax liability dollar-for-dollar. It applies to the full cost of both solar panels and battery storage.
  • Georgia Property Tax Exemption: While solar panels boost your home's resale value, a state-level exemption ensures this added value doesn't increase your Cobb County property tax bill.

How Net Metering Unlocks Your Savings

The key to these savings is Georgia Power's net metering policy. When your panels produce more electricity than your home is using—like on a sunny afternoon while you're at work—that excess power flows to the grid. The utility credits you for this power at their 'avoided cost' rate (around 10¢/kWh). This credit offsets the cost of the electricity you pull from the grid at night, effectively maximizing the value of your solar investment.

Projected Savings

How Much Can You Really Save with Solar?

A properly sized solar panel system in Mableton is projected to save the average family around $733 in the first year. Over the 25-year warranty period of the panels, this can add up to over $25,000 in savings, assuming modest utility rate increases. You're essentially pre-paying for decades of electricity at a fixed, lower cost.
