- System Size: 11.0 kW
- Estimated Upfront Cost: $24,750
- What this includes: Panels, inverters, racking, professional installation meeting Florida's hurricane-code standards, and all necessary permits with Duke Energy Florida.
Optional Battery Storage: For homeowners seeking protection from grid outages, adding a 10 kWh battery like a Tesla Powerwall or Enphase IQ Battery increases the total cost to around $39,750. While this extends the financial payback period, it provides valuable peace of mind during storm season.
Incentives & Tax Credits
Florida's Solar Incentives for 2026
As of 2026, the primary federal residential solar tax credit is no longer available for systems placed in service this year. However, Florida offers powerful state-level incentives that make solar financially attractive:
- Property Tax Exemption: This is a major benefit. Florida law prevents your property taxes from increasing due to the value added by a rooftop solar system. You get the home value boost without the tax burden.
- Sales Tax Exemption: Solar panel systems and all related equipment are exempt from Florida's 6% state sales tax, which provides immediate savings on the upfront cost of your project.
These two state policies are the cornerstones of solar economics in Florida today, ensuring the investment remains accessible and rewarding for homeowners.

How Duke Energy Handles Your Excess Solar Power
Altamonte Springs is in Duke Energy Florida territory, which currently offers a favorable 'net metering' program. This policy is critical to your solar savings.
Here’s how it works: When your panels produce more electricity than your home is using, the excess power flows out to the grid. Duke Energy gives you a full, one-for-one credit for every kilowatt-hour (kWh) you export, valued at the same retail rate you pay for electricity ($0.1535/kWh). These credits offset the power you draw from the grid at night or on cloudy days, effectively zeroing out your usage charges.
Projected Savings
Projected Energy Savings with Duke Energy
Installing an 11.0 kW solar system can generate significant long-term value by offsetting purchases from the grid. Based on current Duke Energy Florida rates, a homeowner in Altamonte Springs can expect to save approximately $1,975 in the first year alone.
- Estimated Annual Savings: $1,975
- Simple Payback Period: 10.6 years
These savings create a clear path to return on investment. Furthermore, solar helps insulate your budget from future utility rate increases. If grid electricity becomes more expensive over time, the power your roof generates becomes even more valuable, improving the system's lifetime value.
