Who installs solar in Summerville
Three kinds of company quote in Summerville. Dedicated solar firms that handle design, permits and installation themselves.
Sales organisations that sign the contract and subcontract the installation, sometimes to a crew from elsewhere in the state. And electrical or roofing contractors that add solar to their trade.
Any of them can do good work; what matters is who is accountable after the sale.
Ask who will be on your roof, whether they are employees or subcontractors, and who answers the phone if the inverter fails in year six.
Summerville’s position matters here. Because the town straddles two utility territories, a company that mostly installs on Dominion homes may default to Dominion assumptions. If you are a Berkeley Electric member, confirm the proposal was built on the co-op’s rider.
Licences a Summerville solar job needs, and how to check them
South Carolina splits solar work across several registrations. Ask for each number, then look it up with SC LLR yourself.
"Solar Panel Installer" is a Residential Specialty registration with the Residential Builders Commission (SC LLR): fabricating, assembling, installing and replacing panels and related components.
Roof mounting: a Residential Builder, a Residential Specialty Contractor with the Roofer classification, or a General Contractor with a roofing classification.
Wiring and connection: a Residential Builder, a licensed residential electrician, or a mechanical contractor with the electrical classification.
Structural roof upgrades: a Residential Builder, a Residential Specialty Contractor with the Carpenter classification, or a General Contractor with building or structural framing.
Ask for a certificate of liability insurance naming you, and ask whether the company holds a Town of Summerville business licence.
How to check a licence: verify a solar installer’s licence. Statewide detail: South Carolina solar installers.
How Summerville installers size and price a system
A careful installer starts from twelve months of your bills.
For a Berkeley Electric member the rider caps size at annual kWh ÷ 1,800 (or average monthly kWh ÷ 150); for a Dominion customer Solar Choice caps it at 20 kW AC, and anything much larger than your use just builds a bank that Dominion pays out at avoided cost in November.
A proposal sized to fill the roof rather than your bill is the most common sign that the seller has not modelled your utility.
Price is usually expressed per watt. We do not publish a Summerville figure; the Summerville cost page shows the fees the Town and the co-op add and how to put several quotes on the same footing.

Warranties and equipment: what to compare in Summerville
Three warranties matter: the panel manufacturer’s product and output warranty, the inverter warranty, and the installer’s workmanship warranty on roof penetrations and wiring. The last is the one most tested by Summerville weather.
Dorchester County averaged 19.18 damaging wind events a year from 2015 to 2025, so ask what the workmanship warranty says about wind damage and leaks, and whether it survives if the installer subcontracted the job.
A warranty is only as good as the company still answering in ten years.

Red flags in a Summerville solar sale
The homeowner credit (§25D) is not available for systems placed in service after 31 December 2025.
That rebate is for Santee Cooper retail customers only.
South Carolina does not allow third-party sales of electricity from a system on your property.
You can cancel a home-solicitation sale until midnight of the third business day after signing, by written notice (SC Code §37-2-502).
The Town requires both; a seller who ignores them has not planned the job.
Sellers must comply with SC consumer-protection law (Title 37); the Office of Regulatory Staff can fine up to $2,500 per violation and void the agreement (SC Code §58-27-2660). Complaints go to the Office of Regulatory Staff.

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

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.
