Common solar problems in Greenville and what they usually mean
| What you see | Likely causes | Who to call first |
|---|---|---|
| Monitoring shows zero | Inverter fault, tripped breaker, lost internet connection | Installer, after checking the Wi-Fi |
| Output down 10–30% with no alert | Shading from new growth, soiling, one failed microinverter or optimiser, a damaged module | Installer |
| Inverter error code | Grid-voltage event, ground fault, overheating | Installer or inverter maker |
| Cracked or shattered glass | Hail or falling branch | Insurer and installer |
| Leak or stain under the array | Failed flashing at an attachment | Installer (workmanship warranty) |
| Duke bill higher than expected | Lower production, or exports netting in a different R-STOU period than assumed | Compare monitoring with the bill, then the installer |
Diagnostic guide. Do not open electrical equipment yourself.
What should you do after a Greenville hail or wind storm?
Greenville County’s hail record is heavier than the coast’s: eight reports of two-inch or larger stones in eleven years, against none of that size in Charleston County over the same span.
Most panels are tested against smaller hail, so a large-stone storm is the one to check after.
From the ground, look for cracked glass, bent frames, displaced panels or rails, and debris on the array; then check monitoring for a drop compared with the day before.
Report storm damage to your homeowner’s insurer promptly, with dated photos, and ask the installer for a written inspection. Keep off the roof. Storm damage and insurance and the solar hazard check.
Is it the inverter, the panels or the connection?
Inverters are the component most likely to fail before the panels. A string inverter stops the whole array; a failed microinverter loses one panel, which monitoring shows as a single dark tile.
A lost Wi-Fi link stops the app but not the panels, so compare the Duke meter’s export reading with the app before booking a call-out. Monitoring shows zero and inverter replacement planner.
Under Duke’s R-STOU and Rider RSC, a bill check needs both numbers by period. A system that is producing normally can still look worse on the bill if your evening use rose, because midday exports cannot offset the 6–9 p.m. on-peak window. Diagnosing underproduction.
What about roof leaks and re-roofing under panels in Greenville?
With a median build year of 1987 for Greenville’s housing (ACS 2023 5-year), many arrays sit on roofs that will need replacing during the system’s life.
Removal and reinstallation is a planned job, not a repair: it needs a roofer and a solar contractor working in sequence, and it may need a permit. A leak at an attachment within the installer’s workmanship warranty is the installer’s to fix. Roof leak after solar and removal and reinstall.
What goes wrong with batteries in Greenville?
Typical battery faults are firmware or communication errors, a battery that will not charge because its mode was changed, and capacity loss accelerated by heat in an uninsulated garage.
If a battery has been set to charge from the grid, check that against Duke’s Rider RSC, which counts storage only when it charges solely from onsite solar. Battery warranties usually cover a stated capacity for a stated term or throughput. More on battery storage in Greenville.
Repair or replace a Greenville solar system?
Repair is the default for inverters, optimisers, wiring and individual damaged modules.
Replacement makes sense when several components are failing at once on an older system, when matching replacement modules are no longer made, or when a re-roof is due anyway and the array is near the end of its warranties.
A full replacement is a new installation: a City of Greenville building permit through the E-Forms portal, the City’s inspection, and a new interconnection review with Duke.
A system that was on legacy net metering keeps that status only until 31 May 2029; ask Duke whether a major change affects it. How Greenville installations are permitted.
Who pays for a solar repair in Greenville?
| Cause | Usually covered by | What you need |
|---|---|---|
| Failed panel, inverter or battery component | Manufacturer warranty | Serial numbers, purchase date, monitoring data |
| Leak, loose wiring, poor installation | Installer workmanship warranty | Contract and warranty terms |
| Hail, wind, falling tree | Homeowner’s insurance, after the deductible | Dated photos, NOAA storm date, installer report |
| Installer out of business | Manufacturer for parts; you pay labour | Installer gone? |
General pattern; your contracts and policy decide.

Primary-source research, data analysis and fact checking
We are a research desk, not a sales floor. We read the statute, the tariff, the code section, the federal filing or the manufacturer data sheet ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. That rule has cost us whole sections, and it is why the rest can be checked.
- 160
- primary sources read and cited
- 228
- figures with a retrieval date
- 115
- federal and state government sources
- 66
- researched pages published
How this desk works
- Primary sources only. Statutes from the legislature’s own publishing system, federal data from the agency that collects it, code text from the adopted edition, manufacturer claims from the data sheet. We do not cite an article that cites a source; we go and read the source.
- Every figure carries its provenance. A named document and the date we retrieved it, so you can check it and so you know how old it is. Retrieval dates are not decoration: an EIA rate from May is a different fact from an EIA rate from August.
- We publish what we could not verify. Every research page carries a section naming the things we tried to establish and could not, and why. A paywalled standard, a state website that refused the request, a manufacturer that publishes no figure at all.
- We separate measurement from modeling from our own reasoning, and label which is which on the page. A laboratory measurement, an assumption inside a modeling tool and our own inference are three different kinds of claim and they are never presented as one.
- We do not sell solar, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Data as of Last verified 5 October 2026. Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
