The short answer

  • Panels don't draw strikes. The National Weather Service says height, pointy shape and isolation are the dominant factors in where lightning strikes, and that "the presence of metal makes absolutely no difference." Panels mounted a few inches above a roof don't make a house taller or pointier.
  • Damage can still happen two ways. A report published by the National Institute of Standards and Technology notes that solar systems are exposed to both direct and indirect lightning effects, and that grid-connected systems are also exposed to surges coming from the power grid.
  • The code covers the basics. Florida's building code adopts the 2020 National Electrical Code, which requires panel frames and racking to be bonded to the grounding system and requires a surge-protective device on new and replaced home electrical services.

Florida's lightning, by the numbers

Texas logged the most lightning of any state in 2025 because of its size, but per square mile Florida led the country:

NOAA calls the stretch from Tampa Bay to Titusville "Lightning Alley," the area with the most yearly lightning in the U.S., and says 90% of its lightning falls from May through October. That's also when solar panels produce the most. Florida also had more lightning-related homeowners insurance claims than any other state in 2025, 5,167 of them averaging $35,993 each, according to the Insurance Information Institute and State Farm, and the same source, citing weather service data, names Florida as the state with the most lightning deaths.

What happens if lightning hits a solar panel

A direct strike sends a huge current looking for a path to ground. On a solar array, the code-required path is the grounding system: the 2020 National Electrical Code says the exposed metal parts of module frames, electrical equipment and conductor enclosures must be connected to an equipment grounding conductor, and racking used to bond the frames must be listed and identified for that job. That path doesn't make a strike harmless, but it gives the current a planned route instead of an unplanned one.

What a strike damages varies. In the NIST case histories, investigators couldn't pin all the damage on direct hits and suggested lightning-induced overvoltages had broken down insulation at the edges of the panels, after which the array's own current did further damage. A direct hit is a reason to have the system inspected before it runs again, even if the panels look fine.

Surges from nearby strikes and power lines

Two ways in

Lightning doesn't have to touch your roof to reach your electronics. It can arrive through the ground and wiring from a nearby strike, or down the utility lines.

The NIST report describes both routes: a grounding network can collect lightning current from nearby strikes, and a grid-connected system is also exposed to surges from the power grid and to differences in ground voltage between the house wiring and the panel wiring. Anything electronic on those wires is exposed, including the inverter, which is why surge protection matters as much as the panels' ruggedness.

That's also why the 2020 National Electrical Code added a whole-home rule: every service supplying a home must have a Type 1 or Type 2 surge-protective device, built into the service equipment or installed right next to it, and the rule applies whenever service equipment is replaced. A solar job that replaces or upgrades your main panel should include one.

What protects a Florida solar system

  • Bonded and grounded equipment. Panel frames, racking and enclosures tied to the grounding system, as the electrical code requires. The permit inspection is where this gets checked.
  • Surge protection at the service. A Type 1 or Type 2 surge-protective device at your main electrical service, required on new and replaced services.
  • A permitted, inspected installation. The Florida Building Code requires an electrical permit, which is what puts a building inspector's eyes on the grounding and bonding. Our permit guide covers the process.
  • Staying clear during storms. The National Weather Service says a house is a safe place in a thunderstorm as long as you avoid anything that conducts electricity, including wiring and electrical equipment. That includes the inverter and the disconnects.

If you think the system took a hit, check its monitoring app for an inverter fault or a sudden drop in output, and have a licensed professional look at it before it's switched back on.

Is lightning damage to solar panels covered?

Usually it falls under your homeowners policy, but check the details. Florida's Department of Financial Services explains that the common HO-3 policy covers the house for all perils except those the policy specifically excludes, while basic HO-1 and HO-2 forms cover only the perils they list. Roof-mounted panels are usually covered as part of the dwelling, the same as the roof; ground-mounted arrays may fall under lower "other structures" limits. Before storm season, ask your insurer how the policy treats surge damage to electronics like an inverter, and what your deductible is. Our solar and homeowners insurance guide covers the rest.

Common questions

Can lightning damage solar panels?

Yes. A direct strike can damage panels, wiring and electronics, and a nearby strike or a surge on the power lines can damage inverters and other electronics without touching the panels. Florida's electrical code requires the panels and racking to be bonded and grounded, and requires surge protection on new and replaced home electrical services.

Do solar panels attract lightning?

No. The National Weather Service says height, pointy shape and isolation are the dominant factors in where lightning strikes, and the presence of metal makes no difference. Panels mounted a few inches above a roof don't make a house meaningfully taller.

What happens if lightning hits a solar panel?

The current looks for a path to ground, which on a code-compliant system runs through the bonded frames, racking and grounding conductors. Panels, wiring and the inverter can still be damaged, so the system should be inspected before it runs again.

Does Florida get more lightning than other states?

Per square mile, yes. Vaisala's 2025 report put Florida first with 305 lightning events per square mile, ahead of Oklahoma, Louisiana, Mississippi and Arkansas. NOAA says the Tampa Bay to Titusville corridor gets the most yearly lightning in the U.S., 90% of it from May through October.

Do I need a surge protector for my solar system in Florida?

Florida's building code adopts the 2020 National Electrical Code, which requires a Type 1 or Type 2 surge-protective device on every service supplying a home, including when service equipment is replaced. If your solar installation replaces or upgrades your main panel, it should include one.

Does homeowners insurance cover lightning damage to solar panels?

Usually. Florida's Department of Financial Services explains that HO-3 policies cover the house for all perils except those specifically excluded, and roof-mounted panels are usually covered as part of the dwelling. Ask your insurer how it handles surge damage to electronics and what your deductible is.
