Common solar problems in Myrtle Beach and what usually causes them
| Symptom | Likely causes on the Grand Strand | Who to call |
|---|---|---|
| System producing nothing | Inverter fault, tripped breaker or disconnect, grid outage (systems without a battery shut down by design) | Installer; Santee Cooper if the grid is out |
| Production lower than last year | Soiling and salt film, shading from new growth, a failed string or optimizer, inverter derating in heat | Installer |
| Monitoring offline | Wi-Fi change or router outage, often after a storm or a change of tenant in a rental | Usually fixable by the owner; installer if not |
| Panels or rails visibly shifted | Wind uplift, loosened attachments | Installer immediately; stay off the roof |
| Cracked glass, scorch marks | Hail, debris, hot spots | Installer; insurer |
| Roof leak below the array | Failed flashing at a penetration | Installer first (workmanship warranty), then roofer |
| Corroded connectors or racking | Salt air, especially on oceanfront blocks | Installer or qualified PV technician |
Diagnosis guide only. Do not open inverters, combiners or disconnects yourself.
Spotting a solar fault on a Santee Cooper bill
Santee Cooper’s DG-25 rider measures what you import and export every hour, so your bill shows both. A month where exports drop to near zero in spring or summer, with no change in how you use power, points to a production problem.
Compare the same month last year rather than the previous month, since output follows the season. A sudden jump in your RG-25 demand charge can also mean the panels were offline during a 3–6 p.m. peak hour they usually cover.
If the system has a battery and your demand charge rose, check whether the battery is still discharging in the peak window. Settings can reset after a firmware update or outage. Why monitoring shows zero and diagnosing underproduction.
Storm damage to solar panels in Myrtle Beach
After a named storm or a severe thunderstorm, look from the ground or a window: are panels sitting flush and evenly spaced, are any rails visible, is any wiring hanging loose, is there debris on the array?
Check the monitoring app for strings that stopped producing. Photograph everything before anything is moved, with dates. Stay off the roof and keep children away from fallen equipment.
Flooding is a separate risk on low-lying lots. The City of Myrtle Beach has AE and VE flood zones and sets a home’s first floor three feet above base flood elevation; inverters, disconnects and batteries mounted lower can be submerged.
Water-damaged electrical equipment usually needs replacement rather than drying out, and must be checked by a licensed electrician before re-energizing.
Roof problems under a Myrtle Beach array
Leaks at attachment points are a workmanship issue for the installer. Re-roofing is the other common job: with the city’s median home built in 1992, many roofs will need replacing while the panels still have years left, which means paying to remove and reinstall the array and re-inspecting the new attachments.
Wind-rated attachment design is engineering work; ask that the reinstall follows sealed drawings as the original did. Roof leak after solar.
When repair or replacement makes sense in Myrtle Beach
Repair a single failed inverter, optimizer, connector or panel. Consider replacement when the inverter is out of warranty and failing repeatedly, when several panels are damaged in one event and matching models are no longer made, or when corrosion has spread through racking on an oceanfront roof.
Replacing panels or inverters can require new City permits, and changing the system’s size or inverter rating means updating your Santee Cooper interconnection; an expansion may also qualify for rebate under the program rules in place at the time, within its 6 kW lifetime cap.

Warranty and insurance for Myrtle Beach solar repairs
Manufacturer warranties cover defects in panels, inverters and batteries; the installer’s workmanship warranty covers the installation, including roof penetrations and wiring. Call the installer first. If the installer has closed, the manufacturers still honour product warranties, usually through a certified service company. If your installer is out of business.
Homeowner’s insurance is what usually pays for storm damage, subject to your policy and its hurricane or wind deductible, which can be a percentage of the dwelling coverage on coastal policies.
Tell your insurer the system exists. Separately, Santee Cooper requires customers to keep liability insurance meeting its interconnection standard for as long as the system is connected. Storm damage and insurance.
Repair cost factors and finding a technician in Myrtle Beach
We do not publish Myrtle Beach repair prices. What moves the cost: whether a warranty applies, roof access on a two- or three-storey coastal house, whether panels must come off, the availability of matching parts, and any new permit.
For a technician, look for the same South Carolina credentials an installer needs: wiring and connection: a Residential Builder, a licensed residential electrician, or a mechanical contractor with the electrical classification.
Check licences on SC LLR. More on how to vet a Myrtle Beach installer.
What to collect before calling for a Myrtle Beach solar repair
Contract, as-built drawings, equipment list, and every warranty with its start date.
Daily production before and after the problem began.
The months before and after, showing exports and the demand charge.
Especially after a storm; your insurer will ask.
The City permit number and the Santee Cooper interconnection approval.
Do not climb onto the roof, open electrical boxes or touch damaged panels or wiring.

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

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.
