Solar in Lexington, SC · as of July 2026
Lexington sits in Lexington 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 Lexington
Built for Lexington roofs, rules, and utilities
Lexington County addresses are served by Dominion Energy South Carolina or Mid-Carolina Electric Cooperative depending on location, which we confirm per address. Exported energy is credited under your utility’s current solar program rather than legacy 1:1 net metering. The Midlands’ long, hot summers make afternoon cooling the biggest driver of the bill, and a well-sized system targets exactly that.
Many Lexington and Lake Murray neighborhoods have HOAs with architectural guidelines, and we prepare the review packet for you. Lakefront and wooded lots get a careful shade study so the design reflects real production, not a best-case guess. Every penetration is 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 Lexington 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 Lexington
Priced at the $2.59 per watt South Carolina benchmark as of July 2026, before and after $South Carolina’s 25% state tax credit. Worked examples to set expectations, not a quote.
| System size | Before incentives | SC 25% credit | Net after credit |
|---|---|---|---|
| 6 kW | $15,540 | $3,885 over 2 tax years | $11,655 |
| 9.5 kWClosest to our ~9.5 kW average system | $24,605 | $6,151 over 2 tax years | $18,454 |
| 12 kW | $31,080 | $7,770 over 3 tax years | $23,310 |
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 Lexington
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.

Lexington specifics
What installing here actually involves
The six things that shape a Lexington 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 Lexington is served by Dominion Energy South Carolina, though Mid-Carolina Electric Cooperative serves many addresses here. It sets how your exported power is credited, which matters more than any equipment choice.
- 02
What shades your roof here
Lakeside lots around Lake Murray are often open to the water on one side, which can be genuinely favourable. Wooded interior lots carry the usual pine and hardwood shading.
- 03
Mounting and structural review
Inland with no salt exposure, though lakefront properties do see higher wind exposure than sheltered lots. Lexington County structural review applies.
- 04
Architectural review and HOAs
Lake Murray communities and the newer suburban subdivisions commonly have HOAs with architectural review, particularly where a roof is visible from the water.
- 05
Outages and climate
Midlands summer cooling load is heavy and aligns well with peak production. Pool pumps are common around the lake and are an excellent daytime load to shift onto solar.
- 06
Permits in Lexington 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.
