Solar Panel System Cost in Cantonment
In early 2026, the estimated cost for a professionally installed 11.3 kW solar panel system in Cantonment is around $25,425. This size is typically sufficient to offset most of the electricity consumption for a home with an average monthly bill of $194.62.
For homeowners seeking protection from power outages, adding a 10 kWh battery for energy storage is an option. A combined solar and battery system would cost approximately $40,425. While the battery provides valuable backup power, it does extend the financial payback period.
Incentives & Tax Credits
Florida's 2026 Solar Incentives
Even with the federal 25D tax credit no longer available for new systems, Florida offers valuable state-level benefits that make solar more affordable:
- Property Tax Exemption: Florida law prevents your property's assessed value from increasing due to the addition of a solar system. You get the home value boost without the higher tax bill. This exemption is secured through 2037.
- Sales Tax Exemption: All solar energy equipment is exempt from Florida's state sales tax, saving you hundreds of dollars on the upfront cost of your system.
These incentives, combined with the long-term bill savings, form the foundation of solar's value. An owned solar system can also be an attractive feature for potential buyers if you decide to sell your home in the future.
Net Metering: Gulf Power Co

Understanding Net Metering in Cantonment
Your system's financial performance is strongly supported by Florida's net metering rules. When your panels generate more electricity than your home is using, the excess power is sent to the Gulf Power Co grid. In return, you receive a credit for every kilowatt-hour (kWh) exported, valued at the full retail rate you would normally pay. This 1-for-1 credit ensures you get maximum value for all the energy your roof produces, significantly reducing or even eliminating your monthly energy charges, aside from fixed connection fees.
Projected Savings
Expected Solar Savings with Gulf Power Co
A 11.3 kW solar system in Cantonment is modeled to produce around $1,975 in electricity savings in its first year. Based on the system cost of $25,425, the estimated payback period is approximately 10.8 years.
This calculation assumes a 3% annual increase in utility rates. If grid electricity from Gulf Power Co becomes more expensive over time, your solar panels will offset costlier power, potentially shortening your payback period and increasing your total return on investment.
