Is installing solar panels in St. Marys a smart investment for 2026?
With strong coastal sun and electricity rates from Okefenoke Rural Electric Member Corp hovering around 14.2 cents per kWh, the potential for savings is clear. However, the key to a successful solar project in Georgia now depends entirely on understanding the state's rules for energy export. Using the power you generate is far more valuable than selling it back to the grid, which reshapes the ideal system design for St. Marys homeowners.

Estimated 2026 Solar Costs in St. Marys
The price of a solar installation depends on system size and whether you include energy storage. Here’s a look at typical costs for a home in the St. Marys area:
- Solar-Only System (9.8 kW): The estimated upfront cost is $24,010. This system is sized to handle the average local electricity consumption.
- Solar + Battery System (9.8 kW panels and 10 kWh battery): The combined system is estimated to cost $39,010. The battery adds energy independence and backup power, a valuable feature in a coastal community.
These modeled costs are a starting point. Your final price will depend on the specific equipment and installer you choose.
Incentives & Tax Credits
Key Financial Incentives for St. Marys Solar Owners
Even without a federal tax credit for homeowners in 2026, Georgia provides important financial support that makes solar a viable long-term investment:
- 100% Property Tax Exemption: This is the cornerstone of Georgia's solar policy. Your Camden County property taxes will not go up after installing a solar panel system, despite the significant value it adds to your home.
- State Sales Tax Exemption: You will not pay Georgia's state sales tax on the purchase of your solar panels and related equipment, which lowers the initial investment cost.

How Okefenoke REMC Handles Excess Solar Power
It's crucial to understand that you don't get a 1-to-1 credit for power you send to the grid. While you buy electricity at the full retail rate (around 14.2 cents/kWh), Okefenoke REMC credits you for exported power at a much lower 'avoided cost' rate of approximately 6.5 cents/kWh. This policy makes it financially advantageous to store and use your own solar power with a battery, rather than selling your excess generation for less than it's worth.
Projected Savings
Projected Bill Savings: Solar vs. Solar + Battery
Your total savings are directly tied to how much of your own solar energy you use. A battery helps bridge the gap between peak sun hours and peak usage hours in the evening.
- A solar-only system in St. Marys is projected to save about $1,446 annually on electricity bills.
- Adding a 10 kWh battery boosts the self-consumption of solar energy, increasing the estimated annual savings to $1,674.
For many in St. Marys, the battery's value extends beyond bill savings. It provides peace of mind with backup power during outages caused by hurricanes or other coastal storms. Furthermore, an owned solar system can be a compelling feature that supports your home's resale appeal to future buyers.
