Solar Panel Repair in Columbia, SC

Why do inverters and monitoring cause most Columbia service calls?

Inverter warranties are usually shorter than panel warranties, so the inverter is the part most likely to fail first. Columbia’s long, hot summers add heat stress to inverters mounted in direct sun on a south or west wall.

An inverter fault shows as zero or sharply reduced output in monitoring; a monitoring fault shows as no data while the inverter light is normal. The inverter replacement planner helps judge repair versus replacement.

On Dominion’s Solar Choice rider, a system that is down for weeks loses more than its own output: banked credits for that month do not build, and the bill reflects full Rate 5 prices, never less than the $13.5 minimum. Catch faults early by checking monitoring monthly.

What should Columbia owners do after a storm?

Richland County’s NOAA record from 2015 to 2025 shows about 33 damaging-wind reports a year, gusts up to 87 knots, seven tornadoes and about $31.8 million in reported property damage across all event types.

After a storm: check monitoring for lost production, look at the array from the ground for lifted panels, shifted rails or debris, photograph anything you see, and keep off the roof.

If the house lost power, a grid-tied system without a battery will be off until the grid returns; that is normal.

Hail is a smaller Columbia risk than wind: 49 reports in eleven years, none 2 inches or larger, largest 1.75 inches, most recently damaging in 2023. Panels are tested against hail, but a damaged panel should be replaced, not patched. Storm damage and insurance.

How do Columbia’s older roofs affect solar repairs?

With a median build year of 1978, many Columbia houses are on a second or later roof. Leaks at attachments usually trace back to flashing or to a roof that aged under the panels.

Replacing a roof under an existing array means removing and reinstalling the system, which needs care to keep warranties intact and may need City permits for the roof and the electrical reconnection. Ask the original installer first: their workmanship warranty may cover attachment leaks. Removal and reinstall.

When is replacement better than repair for a Columbia system?

Repair is usually right for one failed inverter, a damaged panel, a loose connector or a monitoring fault.

Replacement starts to make sense when several components are near end of life together, when parts for an old inverter are no longer available, or when a re-roof would mean removing an older, smaller system anyway.

A replacement is a new installation: it needs City building and electrical permits under the Development Center’s solar checksheet and a new Dominion interconnection review.

Check with Dominion before replacing equipment on a system still on legacy net metering, which runs until 31 May 2029. The steps are on Columbia solar installation.

Who pays for repairs on a Columbia system?

Three warranties usually apply: the panel and inverter manufacturers’ product warranties, and the installer’s workmanship warranty. The manufacturer replaces a failed part; the installer usually handles labour under workmanship cover.

If the original installer has closed, the manufacturer may still honour the part but you will pay a new company’s labour. Storm damage is typically a homeowner’s insurance question; check whether your policy lists the system and whether wind or hail deductibles apply. Leased systems are the lessor’s to repair under the lease.

What should you gather before calling for a Columbia solar repair?

Have ready: the installer’s name and contract, warranty documents, panel and inverter make and model, monitoring screenshots showing when production changed, inverter error codes or light colours, ground-level photos, and recent Dominion bills.
