Enter up to three recent bills. We average them, convert to kilowatt-hours at your own rate, and show the size band that covers your usage. Nothing is sent anywhere until you choose to send it.

Your figures travel with the form, so you do not retype them.
An estimate for planning, not a quote. Real sizing depends on the roof planes, shade and the panel we can actually get, and we confirm it on site. The price band uses $2.54 per watt for Hanahan. Tax treatment depends on your own liability. We are not tax advisers.
Solar in Hanahan
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.

Rates: US EIA Form EIA-861, 2024 averages incl. fixed charges, not tariffs. Export terms as of July 2026.
Hanahan sun, month by month
About 14,300 kWh a year from a south-facing roof with no shade. May is the strongest month at about 1,377 kWh and December the weakest at about 911 kWh.
Your roof will differ. Established lots carry mature canopy; the newer pockets are more open.

Hanahan specifics
Six things shape a Hanahan design. Getting them right is most of the job.
Most of Hanahan is on Dominion Energy South Carolina, but Berkeley Electric Cooperative serves many addresses here. Your utility sets what you are paid for exported power.
Established lots carry mature canopy; the newer pockets are more open. Worth measuring rather than guessing from a satellite image.
Close enough to the coast that wind loading and salt exposure are real design inputs, and Berkeley County structural requirements apply.
A mix of older streets with no HOA and newer subdivisions with active ones. We check which applies before designing.
Storm-season outages reach this part of the metro, and the practical case is backing up essentials rather than the whole house.
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
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 Berkeley County.
Ask who installs and who services the system. Our own crews do both, from Daniel Island.
That is the unshaded ceiling for a 9.5 kW system in Hanahan. A quote far above it, or one with no kWh figure, is guessing.
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.
9.5 kW at $24,130 claims $6,033 over 2 tax years. A quote should show that schedule, not one lump sum.
How it works
We read 12 months of your Dominion Energy bills (or whichever utility your bill names) and check roof age, shade and orientation, plus the coastal attachment detail.
One Hanahan design sized to your usage at the $2.54 per watt benchmark, with annual kWh and the 25% SC credit year by year.
6 approvals in Berkeley County. We file all of them.
Coastal wind-load attachment and salt-rated hardware, then the Berkeley County inspections, which we book and attend.
Dominion Energy approves the interconnection and adds its about $14 a month solar charge. We tell you the day you are live.
Dominion Energy also charges a standing monthly fee of about $14 a month on solar accounts, which we include in payback.

Hanahan solar FAQ
Most of Hanahan is served by Dominion Energy South Carolina, with Berkeley Electric Cooperative on some addresses. We confirm yours during the free assessment, since it sets how your solar is credited.
The one whose licence checks out with SC LLR (the Residential Builders Commission and contractor licensing), whose quote names Dominion Energy and states about 14,300 kWh a year for 9.5 kW, and who services what it installs. Ours does all three, with a lifetime full-system warranty.
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 Hanahan that 9.5 kW system makes about 14,300 kWh a year unshaded; your quote depends on roof, shade and usage.
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.
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.
Qualifying residential systems of 20 kW or less are exempt from South Carolina property tax. Check with the Berkeley County assessor.
68% of Hanahan 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.
Where a Hanahan neighborhood has an HOA, yes. We prepare the architectural-review packet and coordinate approval as part of every install.
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 Berkeley County and book the inspections.
Your roof needs replacing within about five years. Your power bill is under roughly $90 a month. Mature canopy shades your best roof planes.

Coverage
Yes. We install in Hanahan and across Berkeley County, from our office on Daniel Island in the Charleston metro. Dominion Energy South Carolina territory is the one we quote against here, and the permit route is Hanahan’s own.
What "near me" usually means for a solar job
Distance matters less than three things: whether we are licensed in your state, which utility meters your house, and whether a crew can get back to you for service. All three are settled before we quote, not after.
