Solar in Mount Pleasant
Solar companies in Mount Pleasant: what is different here
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.

Choosing a company
How to compare solar companies in Mt. Pleasant
Most solar companies in Mt. Pleasant can source the same panels. What separates them is how they handle three local facts.
Architectural review. 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. Ask which roof plane a layout uses and whether your committee will accept it before you compare prices.
Shade. 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.
Wind and salt. Charleston County is a high-wind coastal zone, so structural review and roof-penetration detailing matter, and salt exposure rules out under-specified hardware.
On price, solar panels in Mount Pleasant run about $2.54 per watt installed. A quote well below that usually has something missing from the list above.
Mount Pleasant specifics
What installing in Mount Pleasant actually involves
Six things shape a Mount Pleasant design. Getting them right is most of the job.
- 01
Your utility, confirmed per address
Most of Mount Pleasant is on Dominion Energy South Carolina, but Berkeley Electric Cooperative serves some addresses. Your utility sets what you are paid for exported power.
- 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 for a rooftop system. We pull all of it and manage the inspection sequence.
Before you sign
How to choose a solar company in Mount Pleasant
- 1
The licence covers the work
Look the business up with SC LLR (the Residential Builders Commission and contractor licensing) before you sign, and ask which licence covers the electrical work in Charleston County.
- 2

Ask who installs and who services the system. Our own crews do both, from Daniel Island.
- 3
About 13,940 kWh a year, in writing
That is the unshaded ceiling for a 9.5 kW system in Mount Pleasant. A quote far above it, or one with no kWh figure, is guessing.
- 4
Dominion Energy, by name
The quote should use about 2.8–4.1¢ per kWh for exports, or the terms of whichever utility your bill names, not a national average.
- 5
The credit, year by year
9.5 kW at $24,130 claims $6,033 over 2 tax years. A quote should show that schedule, not one lump sum.

Mount Pleasant solar FAQ
Common questions from Mount Pleasant homeowners
Who is my electric utility in Mount Pleasant?
Mount Pleasant is served by Dominion Energy South Carolina. Your exact rate and how exported solar is credited depend on your plan and address, which we confirm during your free assessment.
What is the best solar company in Mount Pleasant, SC?
The one whose licence checks out with SC LLR (the Residential Builders Commission and contractor licensing), whose quote names Dominion Energy and states about 13,940 kWh a year for 9.5 kW, and who services what it installs. Ours does all three, with a lifetime full-system warranty.
How much do solar panels cost in Mount Pleasant?
At the $2.54 per watt benchmark, a 6 kW system is about $15,240 installed and a 9.5 kW system about $24,130. South Carolina’s 25% state credit brings those to about $11,430 and $18,098, claimed at up to $3,500 a year. In Mount Pleasant that 9.5 kW system makes about 13,940 kWh a year unshaded; your quote depends on roof, shade and usage.
Does Mount Pleasant have net metering?
One-for-one net metering closed to new applicants on 1 June 2021, and new Dominion Energy South Carolina systems are credited under Solar Choice instead, at roughly 2.8–4.1¢ per kWh for exports. Dominion Energy South Carolina households paid about 14.6¢ per kWh on average in 2024, so every kWh you use at home is worth more than one you export, and we size to your usage rather than to fill the roof.
Is there still a federal solar tax credit in 2026?
Not for homeowners who buy: it ended December 31, 2025. South Carolina’s 25% state credit still applies to systems you own, capped at $3,500 a year with a 10-year carry-forward.
Will solar raise my property taxes in Mount Pleasant?
Qualifying residential systems of 20 kW or less are exempt from South Carolina property tax. Check with the Charleston County assessor.
Should I lease or buy solar in Mount Pleasant?
74% of Mount Pleasant homes are owner-occupied, and for owners the choice is real. Buying, with cash or a loan, means you own the system, can claim South Carolina’s 25% credit, and add an asset to the house. With a lease or power purchase agreement the provider owns the panels, so you cannot claim the state credit for them, and a buyer of your home has to take over the agreement.
Do Mount Pleasant HOAs allow solar panel installation?
Usually, yes, and you won’t manage it alone. Mount Pleasant has many active HOAs and architectural-review boards; we prepare the review packet and coordinate approval as part of every install.
What permits does solar panel installation in Mount Pleasant need?
A building permit and a separate electrical permit for a rooftop system; Standard plan review for systems of roughly 10 kW and above; A zoning review as well for any ground-mounted array; An additional electrical permit where battery storage is included. We pull every one through Charleston County and book the inspections.
What are the downsides of solar here?
Your roof needs replacing within about five years. Do the roof first, or do both together. Your power bill is under roughly $90 a month. Live-oak canopy shades your best roof planes for much of the day.
