Solar panel repair in Hanahan, SC
If your system stopped working
We diagnose and repair solar systems in Hanahan including ones we did not install. Most production problems come down to an inverter fault, a tripped disconnect, vegetation growth or a monitoring failure rather than the panels themselves, and several of those are inexpensive to fix. The assessment is free, and if repair is not economic we will tell you.
Local failure patterns
What actually fails in Hanahan
Proximity is the practical point in Hanahan: we are minutes away, and a system that is offline is losing production every single day it waits. What we most commonly find on the older systems here is an inverter at end of life, or a disconnect that tripped during a storm and was simply left, because the original installer had gone and nobody wanted to be the one climbing into the loft to look.
The utility question comes back at repair time too. Berkeley Electric Cooperative serves many addresses here and Dominion Energy South Carolina serves others, and if a repair changes the system's capacity or replaces the inverter with a different model, the cooperative may want notifying before it goes back on line. We handle that paperwork as part of the job rather than leaving you to discover it after the fact.
Where a system predates the current housing on the street, we also look at what has grown. Established Hanahan lots carry mature canopy and the newer pockets are more open, so two systems a mile apart can have completely different explanations for the same drop in output. Measuring rather than assuming is the only way to tell a shading problem from an equipment problem, and they have very different price tags.
Written for Hanahan specifically. Your own roof, bill and meter still decide the answer, which is what the free assessment settles.
Orphaned systems
Your installer closed. Your system is still yours.
South Carolina has roughly fifteen years of installed rooftop solar behind it, and a good number of the companies that sold those systems are no longer trading. If you are searching for repair in Hanahan because the number on your paperwork does not connect any more, you are not in an unusual position.
Here is the honest picture on your coverage. Manufacturer warranties on your panels and inverter usually survive, because they attach to the equipment rather than to the installer, and they are often 25 years on panels. What does not survive is the original company's workmanship warranty. Nobody can honour that on their behalf, and any company telling you otherwise is not being straight with you.
What we can do is diagnose the fault, tell you which manufacturer coverage still applies and help you make the claim, quote honestly for anything not covered, and stand behind our own work with our lifetime warranty on what we install or reinstall.
Bring whatever paperwork you have, even if it is incomplete. Panel and inverter model numbers and the install date are the useful parts, and we can read most of that off the equipment if the documents are gone.
What usually goes wrong
Six causes, in roughly the order we find them
- 01
Inverter fault or end of life
The most common single point of failure, and usually not the panels.
- 02
Microinverter or optimiser failure
Shows as a few panels underproducing rather than a total outage.
- 03
Tripped breaker or open disconnect
Sometimes the whole problem. Worth ruling out before buying anything.
- 04
Vegetation growth
Common in Hanahan: established lots carry mature canopy; the newer pockets are more open. Worth measuring rather than guessing from a satellite image.
- 05
Roof leak around penetrations
Poor original flashing, usually surfacing years later.
- 06
Monitoring or comms failure only
Production is fine but you cannot see it, often after a router change.
Notice how many of these are not panel failures. Panels are the most durable part of a solar system and usually the last thing at fault. The full diagnostic sequence is set out in what to check when a system stops producing, and inverter replacement covers the most common finding in detail.
Roof replacement
Panel removal and reinstall in Hanahan
One sequence, one party accountable for the roof and the array, and our roof-penetration warranty on the result. What a detach-and-reset involves generally is covered in removal and reinstallation for roof work.
Close enough to the coast that wind loading and salt exposure are real design inputs, and Berkeley County structural requirements apply. A reinstall is also a chance to correct mounting that was marginal the first time.
One thing to know before you plan a reinstall: if your system has to be re-interconnected, Dominion Energy South Carolina's current Solar Choice terms may apply rather than the terms your system was originally signed up under. That is worth understanding before you commit to a sequence, and we will walk you through it.

Maintenance
What actually needs doing here
Solar is low-maintenance, not no-maintenance, and Hanahan has its own list.
- 01
Watch your monitoring monthly
The cheapest maintenance there is. A fault caught in a month costs you a month of production, not a year.
- 02
Vegetation, annually
Established lots carry mature canopy; the newer pockets are more open. Worth measuring rather than guessing from a satellite image.
- 03
Rain does most of the cleaning
Panel washing is oversold. Pollen season and salt film are the exceptions worth a look.
- 04
Inspect after severe weather
Wind-lifted modules and loosened attachments are not always visible from the ground, and this coast gets tested.
- 05
Inverters are consumables
Budget for one replacement across the system's life. That is normal, not a defect, and it is the most common repair we do.
- 06
Keep your documents
Model numbers, install date and interconnection paperwork make every future service call cheaper and faster.
- 07
What the weather does here
Storm-season outages reach this part of the metro, and the practical case is backing up essentials rather than the whole house.
- 08
Re-approval with Dominion Energy South Carolina
An inverter swap or a capacity change usually means notifying Dominion Energy South Carolina, and Berkeley Electric Cooperative serves many addresses here, so we confirm the account first. Exports credit at roughly 2.8–4.1¢ per kWh against about 14.4¢ per kWh (July 2026), which is also why a system running at reduced output costs more than it looks like it does.
- 09
Permit position in Berkeley County
A building permit and a separate electrical permit for a rooftop system. Like-for-like component swaps often do not, but a design change does, and we establish which applies before quoting.
Hanahan solar repair FAQ
Repair questions from Hanahan homeowners
My solar installer went out of business. Can you service my Hanahan system?
Often yes. We diagnose systems we did not install, and this is one of the most common calls we get in South Carolina. What we cannot do is honour another company's workmanship warranty, and we will be straight with you about which parts of your original coverage survive. Your panel and inverter manufacturer warranties usually do, and they transfer with the equipment rather than the installer.
Why has my solar production dropped?
The common causes, roughly in order: an inverter fault or end of service life, a tripped breaker or disconnected string, shading from vegetation that has grown, soiling, a failed optimiser or microinverter on one or more panels, or a monitoring fault where production is fine but reporting is not. A diagnostic visit distinguishes these. Several are inexpensive fixes.
Do I need to remove my panels to replace my roof in Hanahan?
Yes, panels have to come off and go back on, and it is worth planning as one project rather than two. We remove and store the array, coordinate with the roofing work, then reinstall and recommission with fresh flashing and roof-penetration detail. Doing it as a single sequence avoids paying twice for scaffolding and avoids gaps in who is responsible for the roof.
Can you repair panels damaged in a storm?
We assess storm damage and document it for an insurance claim, which matters on the coast. Individual panels can usually be replaced, though matching a discontinued model sometimes means replacing a string. Micro-cracks are not always visible from the ground, so we test electrically rather than judging by eye.
Is it worth repairing an older system or replacing it?
It depends on the fault and the age. An inverter replacement on a healthy ten-year-old array is usually worth it. Widespread panel degradation or a system that was undersized to begin with can favour replacement. We will give you the honest comparison including what Dominion Energy South Carolina's current Solar Choice terms mean for a new interconnection, because that has changed since your system was installed.
Do you charge for a diagnostic in Hanahan?
The initial assessment is free and there is no obligation. If the fix is straightforward we will tell you what it is. If it needs parts or significant labour we will quote it before doing the work, and if the honest answer is that repair is not economic we will say that too.
