The only requirement to appear on this page is a checked state electrical license, confirmed against the state licensing board as part of our approval process, that's why every listing above shows "License checked." Installers are listed alphabetically by default, not ranked by quality, and no installer pays for placement in that order. LumoWatt does not sell ranking. If paid placement is introduced, it will be clearly labeled and will not change the standard list order. Use the sort dropdown above to re-order the list yourself by years in business or how recently we checked a listing. See our editorial policy and listing standards & verification methodology for the full details.

South Carolina has a real, dated record of hurricanes knocking out power at scale. Hurricane Helene, in September 2024, left roughly 1.3 million South Carolina customers without power even though the storm never made direct landfall in the state, with Duke Energy customers in Greenville, Spartanburg, and Anderson counties seeing outage rates near 100 percent, comparisons widely made at the time to Hurricane Hugo, the Category 4 storm that made landfall near Sullivan's Island on September 22, 1989 and remained the state's benchmark disaster until Helene. Hurricane Florence, in 2018, left more than 32,000 South Carolina customers without power.

How long does installation take in Greenville?
The installation itself typically takes 1-2 days once a permit is approved and equipment is on-site, that part doesn't vary much by location. The variable is permit review time: it depends on your local building department's current workload, not on the installer, and can range from about a week to well over a month. Ask your installer for a current estimate, or contact Greenville's permitting office directly (see the permit section above) for the timeline you should actually expect.
