Cost of solar panels in Florida by monthly bill, 2026
Last updated
System size and installed cost for a range of Florida electricity bills, at the state's May 2026 average rate of 15.17 cents per kWh and $2.80 a watt. The last column is the Florida sales tax you do not pay, since solar energy systems are exempt.
Every row comes from the calculator's own formulas. Annual kWh is monthly bill x 12 divided by the rate in dollars per kWh (15.17 cents, the Florida residential average for May 2026 from the EIA). System size is annual kWh divided by 1,400 kWh per kW per year for an unshaded south-facing roof, rounded to one decimal and clamped to 2-20 kW. Installed cost is size x 1,000 x $2.80 a watt. The tax column is 6% of that cost, Florida's general state sales tax rate, which solar energy systems are exempt from under s. 212.08(7)(hh), F.S. The electricity rate and the tax rate are official; the price per watt and the production figure are editable inputs with typical 2026 defaults, not published market rates. No federal credit is applied.
| Monthly bill | Electricity bought per year | System size | Installed at $2.80 a watt | Sales tax not paid (6%) |
|---|---|---|---|---|
| $100 | 7,910 kWh | 5.7 kW | $15,960 | $958 |
| $140 | 11,074 kWh | 7.9 kW | $22,120 | $1,327 |
| $160 | 12,657 kWh | 9 kW | $25,200 | $1,512 |
| $200 | 15,821 kWh | 11.3 kW | $31,640 | $1,898 |
| $250 | 19,776 kWh | 14.1 kW | $39,480 | $2,369 |
| $300 | 23,731 kWh | 17 kW | $47,600 | $2,856 |
- A $160 monthly Florida electricity bill at the state's May 2026 average rate of 15.17 cents per kWh implies about 12,657 kWh a year, which an unshaded south-facing roof covers with roughly 9 kW of solar, $25,200 installed at $2.80 a watt.
- Florida exempts solar energy systems and any component of one from sales tax, so a $25,200 system carries no 6% state sales tax, a saving of about $1,512 before any county surtax.
- For residential property, Florida law says the just value attributable to a renewable energy source device may not be considered in the assessment, so a rooftop solar system should not raise your property tax bill.

What Florida's utilities charge per kWh, from their own tariffs
A solar system in Florida offsets a specific utility's rate, not a state average. The three largest investor-owned utilities publish their residential tariffs; the figures below are theirs, read on the date shown, with the document each came from. Put your own utility's energy plus fuel charge into the calculator above.

How this is worked out
- The federal residential clean energy credit (Internal Revenue Code Section 25D) is not applied. Per the IRS page, it "equals 30% of the costs of new, qualified clean energy property" installed "anytime from 2022 through December 31, 2025".
- It also states "the credit is not available for any property placed in service after December 31, 2025" (irs.gov). The page was last reviewed July 4, 2026; we read it again on our updated date. Confirm your position with a tax professional before letting any 2026 quote net 30% off.
- The default electricity rate of 15.17 cents per kWh is the Florida residential average for May 2026. It was 14.97 cents in May 2025 (EIA, Electric Power Monthly, Table 5.6.A). It is an input: use the figure from your own bill.
- Sizing assumes roughly 1,400 kWh per kW per year for an unshaded south-facing Florida roof. It is scaled by 0.85 for an east or west roof and 0.7 for a shaded or north-facing one.
- These are working estimates, not figures from an official source we can cite today. Treat the suggested size as a starting point, and ask your installer for modeled production for your address.
- Price per watt is your input. The $2.80 default is a typical 2026 Florida quote. It moves with roof type and pitch, tile versus shingle, panel and inverter tier, needed roof work, and the permitting jurisdiction. We publish no Florida market average: no official source we can cite publishes one.
- The sales tax line applies Florida's 6% general state sales tax rate (Florida Department of Revenue) to the system price. Florida exempts "solar energy systems or any component thereof" from sales tax (s. 212.08(7)(hh), F.S.).
- Many counties add a discretionary sales surtax, which is exempt too. So the figure shown is a floor, not the whole saving.
- For residential property, "the just value of the property attributable to a renewable energy source device may not be considered" in determining assessed value.
- Photovoltaic modules and inverters are named as renewable energy source devices (s. 193.624, F.S.). Adding solar should not raise your Florida property tax assessment.
- Nothing here estimates savings. Florida does run net metering for customer-owned renewable generation. But a banked credit's year-end value is not the retail rate: see how Florida net metering works.

Frequently asked
How much do solar panels cost in Florida in 2026?
It depends on how much electricity you buy and your quoted price per watt. For example, a $160 monthly bill at Florida's May 2026 average of 15.17 cents per kWh points to roughly 9 kW. That is $25,200 installed at $2.80 a watt. Enter your own bill, rate and quote; no official source publishes a Florida average.
What is the average cost of solar panels in Florida?
No official Florida average exists; we read installers. Of 55 Florida solar price pages read on 12 October 2026, seven published a price per watt: $2.00 to $3.00, $2.65 in the middle. Palmetto quotes $28,316 cash for a typical 10.53 kW system on its Orlando, Naples and Port St. Lucie pages. The calculator's $2.80 default sits inside that range.
How much does solar cost in Miami or Broward County?
Not published: none of the pages we read in October 2026 printed a Miami-Dade or Broward County price we could take a figure from, including EnergySage's Miami page. Price a Miami or Broward roof the same way as anywhere in Florida: put your own bill, your utility's rate and the per-watt price on your quote into the calculator.
Is the 30% federal solar tax credit available in Florida in 2026?
The IRS page says the 30% credit applies to property installed from 2022 through December 31, 2025. It is not available for any property placed in service after December 31, 2025. That is what we read on irs.gov on this page's updated date. Confirm your case with a tax professional before pricing any federal credit in.
Does Florida charge sales tax on solar panels?
No. Section 212.08(7)(hh), Florida Statutes exempts solar energy systems or any component of one. At Florida's 6% general state rate that is about $1,512 on a $25,200 system, and any county discretionary surtax is exempt too, so the real saving is a little higher.
Will solar raise my Florida property taxes?
It should not. Section 193.624, Florida Statutes provides that for residential property the just value attributable to a renewable energy source device may not be considered in the assessment. Photovoltaic modules and inverters are named in the statutory definition. Your county property appraiser administers it.
What size solar system does a Florida home need?
Divide your annual kilowatt-hours by roughly 1,400 for an unshaded south-facing roof to get a size in kW, then reduce it for shading or an east or west roof. Because banked credits are settled at the utility's rate rather than retail at the annual read, there is little reward for sizing above your own annual usage.
Is a battery worth it in Florida?
Judge it as storm resilience rather than as a bill saving. A standard grid-tied array shuts down in an outage, so a battery is what keeps selected circuits running through a multi-day event. Price it separately from the panels and ask which circuits it backs up and for how long.
