Solar in Hanahan, SC · as of July 2026
Hanahan sits in Berkeley 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 Hanahan
Built for Hanahan roofs, rules, and utilities
Hanahan addresses (29410) are typically served by Dominion Energy South Carolina, with Berkeley Electric Cooperative on some streets, which we confirm per address. Exported energy is credited under your utility’s current solar program rather than the retired 1:1 net metering, and we walk you through exactly what that means for your bill. Being a few minutes away means fast site visits and a team you can actually reach.
Newer Hanahan subdivisions like Tanner Plantation often have HOAs with architectural guidelines, and we prepare the review packet for you. Every roof penetration is sealed carefully and 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 Hanahan 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 Hanahan
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.
| 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 Hanahan
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.

Hanahan specifics
What installing here actually involves
The six things that shape a Hanahan 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 Hanahan is served by Dominion Energy South Carolina, though Berkeley 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
Established lots carry mature canopy; the newer pockets are more open. Worth measuring rather than guessing from a satellite image.
- 03
Coastal mounting and wind load
Close enough to the coast that wind loading and salt exposure are real design inputs, and Berkeley County structural requirements apply.
- 04
Architectural review and HOAs
A mix of older streets with no HOA and newer subdivisions with active ones. We check which applies before designing.
- 05
Outages and climate
Storm-season outages reach this part of the metro, and the practical case is backing up essentials rather than the whole house.
- 06
Permits in Berkeley 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.
