Question 1

Do I need a battery with solar in Florida?

Accepted Answer

Not for savings — Florida's net metering already credits your excess solar. A battery is mainly for keeping essentials on during hurricane outages and rolling blackouts.

Question 2

How long will a battery last during an outage?

Accepted Answer

It depends on what you back up. A single 13.5 kWh battery can run essentials (fridge, lights, phones, a window AC) for roughly 8–12 hours; whole-home backup needs more units.

Question 3

Can a battery power my air conditioner?

Accepted Answer

Yes — a larger battery or multiple units can run a small or window AC. Central AC usually needs a bigger system. We size based on what you choose to back up.

Question 4

How much does a home battery cost in Florida?

Accepted Answer

Roughly $9,000–$12,000 installed per 13.5 kWh unit (for example, a Tesla Powerwall). Your estimate shows the size and cost for your specific backup goal.

Question 5

Will a battery lower my electric bill?

Accepted Answer

Only slightly in most of Florida, where rates are mostly flat. Some utilities offer time-of-use or peak-demand programs where a battery can shave costs; its main value here is resilience.

Question 6

Are batteries safe during hurricanes?

Accepted Answer

Modern lithium-ion home batteries are sealed, indoor-rated, and continue operating through storms when paired with solar — no fuel, no fumes, no noise.
