Is solar worth it in Florida?
Florida earns the Sunshine State name on production, but residential electricity is cheaper than the national average, which lengthens payback. Solar still works well here — especially for homes with large bills from year-round air conditioning.
Here is what the numbers look like for a Florida home using 900 kWh a month (10,800 kWh a year) and covering all of it with solar:
| Item | Estimate for Florida |
|---|---|
| System size needed | 7.4 kW (about 19 panels) |
| Gross cost at $2.75/W | $20,483 |
| Net cost after 30% credit | $14,338 |
| Bill savings per year | $1,605 |
| Payback period | 8.9 years |
| 25-year net savings | $25,784 |
How Florida compares
Florida's average residential electricity rate is about 14.86¢ per kWh, against a national average near 18.56¢. Local solar production runs around 1,450 kWh per year for every kW installed — strong sun by national standards.
Two things decide payback, and rate matters more than most people expect. A high-rate, cloudy state often beats a low-rate, sunny one, because every kWh your panels make is worth more. That is why the sunniest states are not automatically the best places to buy solar.
What the estimate leaves out
State and utility incentives are not included above — rebates, performance payments, and property-tax exemptions vary widely and can shorten payback meaningfully. Net-metering rules matter too: full-retail net metering is worth considerably more than partial export credit. Ask any installer to spell out both before you sign.
If your bill is modest, efficiency may beat solar dollar-for-dollar. Find out what is actually driving your usage with the Electricity Bill Calculator and the Appliance Running Cost Calculator first. If you drive electric, pairing solar with home charging stacks the savings — see the EV Charging Cost Calculator.
Frequently asked questions
Where do these Florida numbers come from?
The electricity rate is the state residential average from the US Energy Information Administration's Electric Power Monthly (Table 5.6.A), March 2026. The production figure is a typical annual output per installed kW for Florida's latitude and climate. Both are planning estimates — your utility and roof will differ.
Does this include a battery?
No. This estimates a grid-tied system with no battery, which is the most common and lowest-cost setup. A home battery adds cost and is generally about backup power rather than extra savings.
Is the 30% federal tax credit guaranteed?
Tax law changes and eligibility depends on your situation. Treat 30% as a planning assumption and confirm the current credit with a tax professional or the IRS before buying.
