Hurricane Prep for Solar Homes: Before, During, and After the Storm

Living with solar in hurricane country doesn't require dread — it requires a plan. Well-installed, permitted arrays have a strong track record in Florida storms because they're engineered to the state's stringent wind code. But the storm still changes how your system behaves, and knowing that ahead of time is the difference between calm and a scramble. Here's the practical version, no fear-mongering.

Before the storm

• Confirm it's actually working: open your monitoring app and check that production looks normal. Going into a storm blind about your baseline makes it harder to tell what the storm changed.
• Know your disconnects: locate your AC and DC solar disconnect switches (usually near the inverter and the meter). You generally don't need to shut anything down for a storm, but knowing where they are matters if there's damage afterward.
• Don't try to remove or cover panels: they're engineered to be attached; a homeowner up on the roof before a storm is a worse risk than the wind.
• If you have a battery, top it off: enter the storm with a full charge so it can carry your essentials from the first minute of an outage.
• Document the system: a few photos of the array and inverter before the storm help with any insurance claim later.

The thing most owners don't expect: solar shuts off in an outage

This surprises almost everyone, so let's be blunt: standard grid-tied solar with no battery stops producing power to your home the instant the grid goes down — even at noon in full sun. It's a mandatory safety feature called anti-islanding that keeps your panels from energizing lines that utility crews may be repairing. It is not a malfunction. But it means 'I have solar' does not mean 'I'll have power in the storm.' Only a battery (or islanding-capable system) keeps your lights on when the grid is down.

Grid-tied solar without a battery gives you exactly zero power during an outage. If riding out storm outages is your goal, the battery is the part that does it — and it's finite, so it's sized to essential circuits, not the whole house forever.

During the storm

If you have a battery and a backup-capable system, it will detect the outage, isolate your home from the grid, and power your backed-up circuits — fridge, some lights, internet, fans. During daylight your panels can recharge it, which is what stretches backup from hours toward days if the sun cooperates. Be realistic about air conditioning: it's a heavy load with a big startup surge, and a multi-day outage under storm clouds is the hardest test a battery faces. Prioritize what truly must stay on.

After the storm

• Safety first: never touch damaged panels, exposed wiring, or a hot or scorched inverter. Treat downed lines and damaged solar gear as live.
• Let the grid stabilize: after utility power returns, grid-tied inverters typically wait several minutes before automatically resuming. Give it time before assuming it's broken.
• Check your app: if production comes back and looks normal, you're likely fine. A flat line, a red inverter light, or a fault code means it needs attention.
• Inspect for physical damage: look (from the ground) for shifted panels, torn flashing, or debris impact. Roof damage under or around the array is a reason to call a pro.
• Don't assume silence means fine: a system can quietly stay offline after a storm and cost you a full season of production if nobody checks.

If your system doesn't come back, throws a fault, or took any physical hit, get it professionally inspected before you shrug it off — especially if the company that installed it has disappeared, which is the SWFL norm. Assure Protect handles post-storm diagnostics and repair on any system, any installer. Reach it at /assure-protect or (954) 952-0151. And if the storm made you rethink powerless outages, that's the conversation to have about a battery.

Questions worth asking

• Does my system have a battery, and if not, do I understand it gives me no outage power?
• Where are my solar disconnects, and what's my normal production baseline?
• After an outage, how long should I wait before assuming my system should have restarted?
• Who inspects and repairs storm-damaged solar in my area now that my installer is gone?
