| 10 kW | $26,500 | $7,950 | $18,550 | 15,184 kWh | $2,050 | 9.0 years | $33,733 | $51,332 |
Solar Energy in Florida: What You Need to Know
Florida is the Sunshine State and ranks among the top states for solar installations. No state income tax means no state solar tax credit, but strong net metering rules, property tax exemptions, and abundant sunshine drive strong solar economics.
Electricity Rates in Florida
The average residential electricity rate in Florida is 13.5 cents per kWh, which is below the national average of approximately 16 cents per kWh. Lower electricity rates mean the payback period is longer, but the 25-year savings are still substantial. As electricity rates continue to rise (averaging 3% per year nationally), the value of solar ownership increases over time.
Peak Sun Hours and Solar Production
Florida averages 5.2 peak sun hours per day, which is a solid level for residential solar. While not the sunniest state, the combination of decent sun hours with modern high-efficiency panels produces meaningful electricity savings throughout the year. A 6 kW system in Florida produces approximately 9,110 kWh per year, accounting for standard system efficiency losses and typical weather patterns.
Florida Solar Incentives and Programs
No state income tax credit (Florida has no income tax). Net metering required for all investor-owned utilities. Property tax exemption for solar — your home value increases but taxes do not. Sales tax exemption on solar equipment purchases.
Incentive Summary for Florida
- Federal Tax Credit: 30% ITC (available through 2032)
- State Tax Credit: None
- Net Metering: Available
- SRECs: Not available
- Avg. Installation Cost: $2.65/watt (before incentives)

Environmental Impact of Solar in Florida
Installing a 6 kW solar system in Florida offsets approximately 7,789 pounds of CO2 per year, which is equivalent to planting 64.3 trees annually. Over the 25-year lifespan of your solar system, that adds up to roughly 194,725 pounds of avoided carbon emissions. Choosing solar energy is one of the most impactful steps a homeowner can take to reduce their carbon footprint and contribute to cleaner air in Florida communities.
