For homeowners in Martinez, managing high summer electricity bills from Georgia Power is a familiar challenge. With average bills around $142, finding ways to reduce that cost is a priority. Rooftop solar offers a direct path to generating your own power, but the financial outcome in 2026 depends heavily on understanding how you get compensated for surplus energy.
Unlike older solar programs, the current structure makes using your own solar power far more valuable than sending it back to the grid. This shift changes the conversation from just panels to a complete home energy system.

Estimated Solar Panel Costs in Martinez (2026)
In early 2026, the estimated cost for a professionally installed rooftop solar system in the Martinez area is around $2.45 per watt. For a typical 9.2 kW system designed to offset a significant portion of a $142 monthly bill, the total cost would be approximately $22,540.
- Solar-Only System (9.2 kW): An estimated gross cost of $22,540.
- Solar + Battery System (9.2 kW with 10 kWh battery): An estimated gross cost of $37,540.
These prices reflect installation in 2026 and do not include the federal residential clean energy credit, which is no longer available for systems placed in service after 2025. The primary financial benefits now come directly from bill savings and state-level incentives.
Incentives & Tax Credits
Georgia's Solar Incentives for 2026
While the 30% federal tax credit is no longer a factor for new installations, Georgia homeowners can still benefit from important state-level policies that make solar a better long-term investment.
- Property Tax Exemption: Georgia law ensures that adding a solar panel system will not increase your property taxes. The value added to your home by the panels is exempt from your property tax assessment, which is a significant long-term financial benefit.
- No State Sales Tax: While not a direct incentive, Georgia does not have a specific sales tax exemption for solar equipment, so standard sales tax applies to the materials portion of the contract.
An owned solar system can also be an attractive feature for potential buyers, possibly enhancing your home's resale appeal when it's time to sell.

Understanding Export Rates with Georgia Power
Georgia does not have a statewide net metering mandate that requires utilities to credit solar exports at the full retail rate. Instead, utilities like Georgia Power compensate homeowners for surplus energy based on an "avoided cost" rate. This rate reflects what it would cost the utility to generate that power themselves, which is significantly lower than the retail price they charge customers.
This is why a solar battery is strongly recommended. By storing your excess solar energy generated during the day, you can use it during the evening and overnight hours. This allows you to avoid selling it to the grid for a low price and then buying it back at the full retail price just hours later. A battery puts you in control of your own energy, maximizing your savings and providing resilience against grid outages.
Projected Savings
How Solar Creates Value on Your Georgia Power Bill
With electricity from Georgia Power costing around $0.14 per kWh, every kilowatt-hour of solar energy you use directly in your home is a direct saving. However, any surplus power you export to the grid is credited at a much lower rate, estimated around $0.065 per kWh. This difference is why maximizing self-consumption is key.
- A 9.2 kW solar-only system is modeled to save a Martinez homeowner around $1,286 annually, leading to a payback period of about 15.8 years.
- Adding a 10 kWh battery increases your ability to use your own solar power after sunset. This boosts annual savings to around $1,462, though the higher initial cost extends the payback period to roughly 19.1 years. The battery also provides valuable backup power during outages.
Furthermore, if grid electricity becomes more expensive over time, the value of the energy your system produces will grow, potentially shortening the long-term payback period.
