# Florida Solar Cost Calculator

> Solar panel cost calculator for Florida: size a system from your electric bill, price it per watt, and see the sales and property tax exemptions Florida law gives.

## Key facts

- 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.

## Data

- Florida solar cost by monthly bill, 2026. Methodology: 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.
