Solar Panel System Costs in Tavares (2026)
A typical solar installation designed to offset a monthly electric bill of around $175 in Tavares costs approximately $24,525 before any incentives. This estimate is for a 10.9 kW system, which is a common size for homes in the area.
- Solar-Only System (10.9 kW): The estimated gross cost is $24,525.
- Solar + Battery System (10.9 kW with 10 kWh battery): Adding a battery for backup power brings the estimated cost to $39,525. A battery provides power during grid outages but doesn't shorten the financial payback period under Duke Energy's current rules.
These prices reflect the total cost of equipment and installation. Florida's tax exemptions, discussed below, provide significant savings on this initial investment.
Incentives & Tax Credits
Florida's Solar Incentives for 2026
While the federal 25D tax credit for residential solar systems placed in service after 2025 is no longer available, Florida offers powerful state-level incentives that make solar a strong investment:
- Property Tax Exemption: This is a major benefit. Florida law exempts 100% of the value added by a solar system from your property tax assessment. Installing a $24,525 system will not increase your property taxes. This exemption is secured through 2037.
- Sales Tax Exemption: Solar energy equipment is exempt from Florida's 6% state sales tax, saving you over $1,400 on a typical system purchase right from the start.
Additionally, an owned solar system can be an attractive feature for potential buyers, potentially improving your home's resale appeal in the competitive Central Florida market.

How Duke Energy's Net Metering Works
Tavares is in Duke Energy Florida territory, which currently offers a retail-rate net metering program. This is one of the most beneficial policies for solar owners.
Here’s how it works: When your panels produce more electricity than your home is using, the excess power is sent to the grid. Duke Energy gives you a 1-for-1 credit for every kilowatt-hour (kWh) you export. These credits are then used to offset the cost of any electricity you pull from the grid at night or on cloudy days. This policy ensures you get full value for every bit of energy your system produces, maximizing your savings.
Projected Savings
Projected Monthly and Annual Solar Savings
Installing a 10.9 kW solar system in Tavares can generate significant savings. Based on Duke Energy's current rate of $0.137/kWh, homeowners can expect to save approximately $1,742 annually. This translates to an average of over $145 per month off your electric bill.
With a net cost of $24,525, the simple payback period is about 11.6 years. After this point, the electricity your system generates is pure savings for the remainder of its 25+ year lifespan. As utility rates rise over time, the value of the energy you produce at home will only increase, offering a powerful hedge against energy inflation.
