Head-to-Head Breakdown
Solar + Battery Storage
Features and considerations
- Provides power during grid outages — critical in Florida hurricane season
- Store excess solar production for use at night
- Hedge against Florida's time-of-use (TOU) utility rates
- Reduces grid dependence — full energy independence possible
Limits and questions
- Limited capacity — 1–2 Powerwalls won't run whole home AC for days
- Extended Florida hurricane outages exceed battery runtime
Solar Only (Grid-Tied)
Features and considerations
- Florida net metering credits excess production at retail rate
- Simpler system — no battery maintenance or degradation concerns
- Maximum long-term ROI per dollar invested
Limits and questions
- No power during grid outages — system shuts off automatically for grid safety
- Cannot provide hurricane season backup
- Florida net metering policy changes could affect future value
- No protection against FPL's shifting rate structures

Frequently Asked Questions
Does Florida's net metering policy affect whether batteries are worth it?
Florida currently has full retail net metering, meaning excess solar production is credited at the retail electricity rate. With full retail net metering, batteries primarily provide backup value rather than financial arbitrage value.
How long can a Tesla Powerwall run a Florida home during a hurricane?
For hurricane season backup, most Florida homeowners who want meaningful backup pair 2–3 Powerwalls with solar (which can recharge the batteries during daylight hours between storms) or supplement with a generator.
Can I add battery storage to my existing Florida solar system?
Yes — most major battery systems (Tesla Powerwall, Enphase IQ Battery, SolarEdge) can be retrofitted to existing grid-tied solar systems.
