Quick Answer
Miami is excellent for solar with 248 sunny days and 5.2 peak sun hours (NOAA data). FPL rates of $0.13-0.16/kWh (and rising) mean 8-12 year paybacks. The real case for Miami solar is hurricane resilience—battery backup during multi-day outages is worth real money. Budget $2.50-3.10/watt for solar, plus $10,000-15,000 for recommended battery storage.
Solar in Miami
Miami is the Sunshine State's largest metro, and lives up to the name with excellent solar conditions year-round. According to NOAA climate data, Miami averages 248 sunny days annually. Rising FPL rates and hurricane concerns are driving more homeowners toward solar with battery backup.
From my experience:I'll be honest—if I lived in Miami, I wouldn't even consider solar without battery storage. Not just for the bill savings, but for the peace of mind. After seeing what happened with Hurricane Ian and previous storms, being able to run your fridge and a window AC unit for days while everyone else sweats it out? That's worth real money. Factor in the resilience value when you're doing the math, not just the kWh credits.

FPL Net Metering
Florida Power & Light (FPL) serves most of Miami-Dade County and offers net metering for residential solar customers.
FPL Solar Programs
- Net metering: 1:1 credit for excess generation
- Monthly rollover: Credits carry forward indefinitely
- No expiration: Credits don't expire at year-end
- System limit: Up to 115% of historical usage
FPL Net Metering
FPL offers true net metering with 1:1 credits that roll over monthly with no annual true-up. This makes solar economics in Miami straightforward—what you export, you get back as credit. (Source: utility tariff filings and DSIRE Database)

Hurricane Considerations
Solar and Hurricanes
- Panel ratings: Most panels rated for 140+ mph winds
- Proper installation: Critical for hurricane zones
- Roof condition: Ensure roof is hurricane-ready before solar
- Insurance: Verify coverage includes solar panels
Battery Backup Value
- Outage protection: Keep critical loads running during outages
- Post-storm power: Generate electricity even when grid is down
- Peace of mind: Resilience has real value in hurricane zones
- FEMA statistics: Average Miami outage after major storm: 3-14 days
Battery Recommendation
In Miami, battery storage has value beyond bill savings. Post-hurricane outages can last days to weeks. Solar + battery keeps lights, refrigeration, and AC running when neighbors are in the dark. (Source: manufacturer specifications and EnergySage data)
Miami-Specific Installation
- Miami-Dade approval: Strictest building code in US
- Hurricane straps: Required for all roof attachments
- Permit process: More thorough than most cities
- Experienced installers: Choose companies familiar with Miami code
Production Estimates
- Annual production: 1,400-1,550 kWh per kW installed
- 8 kW system: ~11,200-12,400 kWh/year
- Best months: March-May (before summer storms)
- Summer: Afternoon thunderstorms reduce production slightly
The Bottom Line
Miami is a good solar market with unique considerations. The combination of abundant sunshine, FPL's favorable net metering, and the value of battery backup during hurricane season makes solar + storage particularly compelling.
Key points:
- FPL offers true 1:1 net metering with indefinite rollover
- Property and sales tax exemptions reduce effective cost
- Battery storage adds resilience during hurricane outages
- Choose installers experienced with Miami-Dade building code
- Expect 8-12 year payback; faster when you value backup power
