Solar Panel Repair in Charleston, SC

Storm damage to solar panels in Charleston

Charleston County’s storm record is a wind record. Between 2015 and 2025 NOAA logged about 24 damaging wind events a year, gusts to 83 knots and 21 tornadoes; hail was reported 61 times but never at 2 inches or more, and the largest stone was 1.75 inches.

Wind damage to an array usually starts at the edges and corners of the roof, where uplift is highest, and at attachments that were under-sized or poorly sealed.

After a named storm or a tornado warning, check the monitoring and walk the house from the ground. Photograph anything out of place before it is moved, then call the installer and your insurer.

Do not climb onto the roof or touch loose wiring: a damaged array can still be live in daylight even when the grid is down. Insurance questions are on solar storm damage and insurance.

Flooding and salt air on Charleston solar equipment

Inverters, disconnects and batteries are often mounted on garage or exterior walls, which puts them at risk where tidal or storm flooding reaches.

The City requires 2 feet of freeboard above base flood elevation for new construction and 1 foot for residential substantial improvements, and Charleston County’s flood map in force dates from 29 January 2021.

Equipment that has been under water should not be re-energised until a licensed electrician or the installer has inspected it.

If the replacement goes back on the same wall, ask whether it can be raised.

Salt air near the harbour, rivers and marsh corrodes exposed fasteners, connectors and enclosures faster than inland. Corrosion shows up as intermittent faults and ground-fault errors. Ask the installer to check terminations and enclosures on any service visit, and check whether your equipment warranty has terms for coastal sites.

Roof leaks and removing panels for a Charleston re-roof

A leak under an array is usually at a penetration, and the installer’s workmanship warranty is the first place to look.

The median Charleston home was built in 1994 (ACS 2023 5-year), so many arrays sit on roofs that will need replacing during the system’s life.

Removing and reinstalling an array is a planned job, not a repair: it needs a licensed crew, coordination with the utility, and a City permit if the electrical work or attachments change.

Ask for a written price and who re-certifies the attachments to the City’s 150 mph design wind.

Warranty and insurance: who pays for a Charleston solar repair

Three parties may be responsible. The installer’s workmanship warranty covers its own work, such as leaks and loose connections. Manufacturers cover their products: panels, inverters and batteries, each with its own term and claim process, usually run through the installer.

Your homeowners policy may cover storm damage to a system that is part of the house, subject to the deductible; many coastal policies carry a separate windstorm or named-storm deductible, so check yours.

If your installer has gone out of business, the manufacturer warranties usually still stand, but you will need another licensed company to diagnose and file the claim. What a workmanship warranty should cover.

What drives the cost of a solar repair in Charleston

We do not publish Charleston repair prices. The cost depends on whether the fault is covered by a warranty, whether the work needs the roof, the parts involved, and whether the City needs a permit.

A repair that changes wiring or attachments may need an electrical or building permit with its $40 application fee, and a failed re-inspection costs $100 under the City’s fee schedule.

Ask for a written diagnosis and quote before work starts, and ask whether the diagnostic visit is credited against the repair.
