Solar panel repair across South Carolina

If your original installer no longer trades

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 the number on your paperwork does not connect any more, that is a common position rather than an unusual one.

We diagnose systems we did not install. What we cannot do is honour another company’s workmanship warranty, and we will be straight about which parts of your original coverage survive. Manufacturer warranties on panels and inverters usually do, because they attach to the equipment rather than to the installer, so it is worth locating your original paperwork before assuming you have nothing.

Bring whatever you have: the original proposal, the equipment list, any monitoring login, and recent bills. Monitoring history in particular shortens diagnosis considerably, because it shows when production changed rather than only that it did.

Most production problems are not panel failures

Panels fail rarely. The more common causes of a system underproducing are inverter faults, communication or monitoring dropouts that make a working system look dead, string or connector issues, and shading that has grown in since installation. Tree growth over ten years is a genuinely common and entirely undramatic explanation.

Soiling matters less in most of our territory than people expect, with the exception of specific local conditions. A diagnosis that jumps straight to cleaning without establishing production history is skipping the step that identifies the actual fault.

Roof leaks near mounting points are a separate category and a more urgent one. They often appear years after installation and not obviously beneath the panel responsible, which is why flashing detail is worth getting right at install and worth inspecting properly when a leak appears.

Failure patterns differ by market (salt-air exposure on the coast is a different profile from inland heat cycling), and each page below covers what we actually find in that town rather than a generic checklist.

Maintenance, monitoring and when to replace rather than repair

The single most useful thing you can do for an existing system is check that its monitoring still reports. A surprising number of systems have been silently offline for months because a router was replaced and nobody reconnected the inverter, and a system nobody is watching can underproduce for a year before a bill makes it obvious.

Inverters are the component most likely to need replacing within a system’s life. String inverters typically have a shorter service life than the panels they serve, so an original inverter on a ten to fifteen year old array reaching the end of its warranty is an expected event rather than a fault. Planning for it beats being surprised by it.

Whether to repair or replace depends on the age of the rest of the system and on what is still supported. Equipment from manufacturers that have exited the market can be difficult to source, which sometimes makes replacing a component with a current equivalent more sensible than chasing a like-for-like part.

We will tell you when a repair is not worth doing. An old, small, partially shaded array with a failed inverter is sometimes better addressed as a replacement decision than a repair one, and that is a conversation worth having with the numbers rather than avoiding.

How to use these pages

Start with your town rather than the state. Every page below is grouped by the utility that serves it, because that is the variable doing the most work, and a statewide average is a number that applies to nobody in particular.

Then check the assumption behind any figure you are comparing. Two quotes for a similar system can differ enormously on their twenty-five year totals purely because of what each assumed about export credits and rate escalation, and neither assumption is usually stated on the front page.

If your town is not listed, it is worth asking rather than assuming we do not cover it. We install statewide from a Daniel Island office, and the page list reflects where we have enough verified local detail to publish something useful rather than the limit of where we work.

What we need to give you a real number

Twelve months of electricity usage. Not one bill, twelve. A system sized from a summer peak is oversized for the year and one sized from a mild month disappoints every August, and neither error is visible until the system is on the roof. Twelve months also shows us the shape of your consumption across the day, which is what determines how much of your own production you will actually use rather than export.

Confirmation of who serves your meter, read off the bill rather than inferred from your address. In the Charleston metro especially, territory boundaries run between streets, and modelling the wrong provider produces a confident answer to the wrong question.

Some idea of your roof: its age, its covering, and whether anything has grown up around it since you moved in. Roof age is the detail that most often changes our recommendation, because installing over a roof with a few years left means paying to remove and reinstall the array later.

And your own horizon. A household planning to move within a few years is making a resale decision rather than a payback decision, and those are different questions with genuinely different answers. Telling us early saves everyone a survey.

With those four things we can give you figures rather than a projection built on averages. Without them, anyone quoting you a payback period is guessing with a straight face.

Common questions

My solar installer went out of business. Can you help?

Yes, we diagnose systems we did not install. We cannot honour another company’s workmanship warranty, and we will be straight about which parts of your original coverage survive: manufacturer warranties on panels and inverters usually do, because they attach to the equipment.

Why is my solar system producing less than it used to?

Most often an inverter fault, a monitoring or communication dropout that makes a working system look dead, a string or connector issue, or shading that has grown in since installation. Panel failure is comparatively rare.

Do solar panels need cleaning in South Carolina?

Less often than people expect in most of our territory, with exceptions for specific local conditions. A diagnosis that jumps to cleaning without establishing production history is skipping the step that finds the actual fault.

What should I bring to a repair assessment?

The original proposal and equipment list, any monitoring login, and recent bills. Monitoring history shortens diagnosis considerably because it shows when production changed rather than only that it did.

Can you fix a roof leak around my solar mounts?

Yes. Leaks near mounting points often appear years after installation and not directly beneath the panel responsible, so they need proper investigation rather than sealing the nearest visible point.
