For homeowners served by Duke Energy, rooftop solar presents a direct way to reduce or even eliminate that monthly bill. Looking ahead to 2026, the key question is whether the savings justify the investment, especially with changes to federal incentives. The answer lies in Duke's policies and Florida's supportive state laws.

How Much Do Solar Panels Cost in Seminole?
To achieve the savings mentioned above, a typical home in Seminole requires a 10.4 kilowatt (kW) solar system. In early 2026, the all-in cost for a professionally installed system of this size is approximately $23,400.
- System Size: 10.4 kW
- Estimated Net Cost: $23,400
- Average Cost per Watt: $2.25
This upfront investment is the primary driver of the system's long-term value. For those concerned about power outages, particularly during hurricane season, a battery can be added. A combined solar and battery system costs around $38,400. While this provides valuable peace of mind, the solar-only configuration has a quicker financial payback of 11.2 years.
Incentives & Tax Credits
Florida's Pro-Solar Tax Policies
While the landscape of federal incentives has changed for 2026, Florida continues to offer powerful benefits that make going solar financially attractive.
- 100% Property Tax Exemption: Under Florida law, the value added to your home by a solar installation is exempt from property taxes. This means you can increase your home's value without increasing your tax bill.
- Sales Tax Exemption: All solar energy systems are exempt from the state's sales tax. On a $23,400 system, this saves you more than $1,400 at the time of purchase.
These incentives, combined with the energy savings, contribute to a strong return on investment. Furthermore, an owned solar system can be a positive feature when selling your home, potentially enhancing its marketability.

Understanding Duke Energy's Net Metering Program
A key reason solar works so well in Seminole is Duke Energy's net metering policy. This rule ensures you get full value for every bit of solar energy you produce. When your panels generate more power than your home needs, the surplus energy flows to the grid. Duke Energy credits your monthly bill at the full retail rate for this exported power. It's a simple, 1-to-1 exchange that maximizes your savings and is essential to achieving the payback period calculated for your system.
Projected Savings
Expected Solar Savings with Duke Energy
A properly sized solar panel system in Seminole can deliver significant financial returns. Based on Duke Energy's rate of $0.137 per kWh and the excellent sun exposure in Pinellas County, a 10.4 kW system is projected to save the average homeowner $1,742 in electricity costs during its first year.
With a payback period of around 11.2 years, the system pays for itself and then continues to provide free electricity for the remainder of its 25+ year lifespan. This is not only about today's bill; it's also a smart hedge against rising utility costs. If grid power from Duke Energy becomes more expensive in the future, the value of the energy you generate yourself increases right along with it.
