Florida solar panel cost calculator

Estimate system size, panel count, gross cost, annual production, and savings using defaults for Florida. Enter an address or ZIP Code below to replace them with live location data.

Warm climate and cooling load can make offset valuable; hurricane exposure and roof age deserve extra review.

Decision brief

What changes the decision in Florida

These state-specific checks are not included in a generic national quote. Resolve them before comparing payback claims. Supporting rules and official references are collected at the end of this page.

  1. 01Before you sign

    Confirm annual excess-credit treatment

    Florida net metering offsets on-site consumption, but year-end excess treatment and interconnection details belong to the serving utility tariff. Ask for the exact written schedule.

  2. 02Before you sign

    Document roof condition and wind design

    Florida roof provisions address wind resistance for rooftop photovoltaic systems. A calculator cannot determine the roof's remaining life, load path, or fastening design; put those responsibilities in the contract.

  3. 03Before you sign

    Verify both state tax exemptions

    Florida separately addresses renewable-device value in property assessment and qualifying equipment under sales-tax law; confirm invoice treatment before signing.

Verified state policy

What can reduce your cost in Florida

Review these 4 statewide or utility-level policy signals before comparing net cost. They are not automatically applied because eligibility, tax liability, utility territory, equipment, and program capacity can change.

Policy configuration verified .

Policy sources
Not statewide01
Broad state solar cash rebate

$0 statewide

Florida has no broad state-funded residential PV cash rebate. Utility, local loan, and PACE programs are separate.

Generally available02
Solar sales and use tax exemption

100% exempt

Qualifying solar systems and certified integral components are exempt from Florida sales and use tax.

Generally available03
Residential property-tax abatement

100% of added solar value

For qualifying residential property, the value added by a renewable energy source device is excluded from assessed value.

Eligibility applies04
Investor-owned utility net metering

Retail-rate monthly energy credit

Qualifying customer generation offsets monthly usage at the applicable retail energy rate. Annual excess and interconnection details follow the serving utility's approved tariff.

Calculation walkthrough

How we calculate for Florida

A worked example using this page's baseline assumptions. Calculator results above change when you edit the inputs.

Baseline inputs

Illustrative 1,000 kWh/month household

Solar resource
4.916 peak sun hours/day
Modeled system loss
20% loss / 80% delivered
Household electricity use
12,000 kWh/year
Energy value
$0.1510 retail / $0.04 export
  1. 01

    Annual output per 1 kW

    Location and production losses

    4.916 h/day × 365 days × 80% delivered

    1,435 kWh/year

  2. 02

    Required system capacity

    Annual demand divided by output

    12,000 kWh ÷ 1,435 kWh per kW

    8.36 kW

  3. 03

    Energy-based panel count

    Rounded up; entered usable roof area can cap the result

    8.36 kW ÷ 0.4 kW per panel → round up

    21 panels

    8.4 kW

  4. 04

    Estimated first-year value

    Retail offset plus export credit

    12,000 kWh × $0.1510 + 58 kWh × $0.04

    $1,814/year

Model notes and limitationsSources and scope

Production baseline

NLR PVWatts v8 modeled a 1 kW array at 20° tilt and 180° azimuth for Orlando, FL 32801, USA.

Energy valuation

Self-consumed production offsets the retail rate. Production above annual use is valued at the configured export rate; utility tariffs may use different timing or settlement rules.

Not included

Roof shading, structural conditions, hourly tariffs, financing, maintenance, incentives, and tax eligibility require separate verification.
