Solar in Mount Pleasant, SC · as of July 2026

Mount Pleasant sits in Charleston County and is served by Dominion Energy South Carolina. Whether solar works at a given address here depends on that utility's current export terms, how much of your production you use on site, your roof's condition and orientation, and any review your community or locality applies. We confirm the utility from your bill before designing, because it decides more of the outcome than any equipment choice on a quote.

Solar in Mount Pleasant

Built for Mount Pleasant roofs, rules, and utilities

Mount Pleasant homes are served by Dominion Energy South Carolina, whose Solar Choice program credits exported power on a time-of-use basis rather than the older 1:1 net metering, which closed to new applicants on 1 June 2021. Mount Pleasant is one of the most HOA-dense markets in the Lowcountry, so how a system looks and where panels sit often matters as much as how it performs.

Communities like I’On, Old Village, and Park West have active architectural-review committees with real rules on panel placement and street visibility. We design within those rules and prepare the review packet for you, so approval is our job, not yours. Coastal exposure also means we detail every roof penetration carefully, backed by our lifetime roof-penetration warranty.

Handling the paperwork most homeowners dread is our job: HOA and architectural-review coordination, permitting, and the utility interconnection. See what our lifetime warranty covers.

You get the same crew, the same standards, and the same lifetime warranty in Mount Pleasant as anywhere else we work in South Carolina. We're a South Carolina company, headquartered in the Charleston area and built to serve homeowners statewide.

Honest numbers

What solar actually costs in Mount Pleasant

Priced at the $2.54 per watt local benchmark as of July 2026, before and after $South Carolina’s 25% state tax credit. Worked examples to set expectations, not a quote.

Illustrative installed cost in Mount Pleasant. The state credit is capped at $3,500 per tax year, so larger systems are claimed across more than one return.
System size Before incentives SC 25% credit Net after credit
6 kW $15,240 $3,810 over 2 tax years $11,430
9.5 kWClosest to our ~9.5 kW average system $24,130 $6,033 over 2 tax years $18,098
12 kW $30,480 $7,620 over 3 tax years $22,860

The number most quotes leave out: because Dominion Energy South Carolina credits exported power at roughly 2.8–4.1¢ per kWh rather than at retail, how much production you use on site drives your payback more than which panels you buy.

2026 incentives

What you can actually claim in Mount Pleasant

The federal residential credit ended for systems placed in service on or after January 1, 2026. Any quote still applying 30% federal is wrong, and the gap runs to thousands of dollars.

$South Carolina’s 25% state tax credit did not expire. It is worth 25% of installed cost, capped at $3,500 per tax year, with a 10-year carry-forward and a further limit of 50% of your state tax liability. Qualifying systems of 20 kW or less are exempt from property tax, and equipment is exempt from state sales tax.

Dominion Energy South Carolina runs no upfront residential rebate, so there is no cash-back programme to stack here. We would rather say that plainly than let you find out after signing.

Mount Pleasant specifics

What installing here actually involves

The six things that shape a Mount Pleasant design. Getting these right is most of the job, and it is where a local crew beats a national sales operation.

  • 01

    Your utility, confirmed per address

    Most of Mount Pleasant is served by Dominion Energy South Carolina, though Berkeley Electric Cooperative serves some addresses. It sets how your exported power is credited, which matters more than any equipment choice.

  • 02

    What shades your roof here

    Established neighbourhoods carry heavy live-oak canopy, while newer subdivisions are often close to unshaded. Which side of that your street falls on changes the design substantially.

  • 03

    Coastal mounting and wind load

    Charleston County is a high-wind coastal zone, so structural review and roof-penetration detailing matter, and salt exposure rules out under-specified hardware.

  • 04

    Architectural review and HOAs

    Mount Pleasant is one of the most HOA-dense markets in the Lowcountry, with active architectural-review committees that have real rules on panel placement and street visibility.

  • 05

    Outages and climate

    Multi-day hurricane-season outages are the design case here, which favours backing up essentials well over trying to run the whole house.

  • 06

    Permits in Charleston County

    A building permit and a separate electrical permit, with plan review above roughly 10 kW. We pull all of it and manage the inspection sequence.
