Bill-to-size
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 size band will appear here.
Add one bill and your rate to start.
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 $2.59 per watt, a statewide figure. Tax treatment depends on your own liability. We are not tax advisers.
Solar in Walterboro
Walterboro-area addresses are served by Dominion Energy South Carolina or Edisto Electric Cooperative depending on location, which we confirm per address. Exported energy is credited under your utility’s current solar program rather than the retired 1:1 net metering. Larger rural lots here often open up ground-mount options when a roof isn’t ideal.
Many Colleton County properties have fewer HOA restrictions than the coastal towns, which can simplify design, though where an HOA applies we prepare the review packet for you. Older roofs and outbuildings get careful mounting and sealed penetrations, backed by our lifetime roof-penetration warranty.

Some addresses
For comparison: South Carolina average 14.23¢ · U.S. average 16.48¢. South Carolina had 40,055 net-metered home solar systems at the end of 2024.
Rates: US EIA Form EIA-861, 2024 averages incl. fixed charges, not tariffs. Export terms as of July 2026.
Walterboro 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. Wooded rural lots are the norm, so shading is the usual constraint on a roof array.

Walterboro specifics
Six things shape a Walterboro design. Getting them right is most of the job.
Most of Walterboro is on Dominion Energy South Carolina, but Edisto Electric Cooperative serves many addresses here. Your utility sets what you are paid for exported power.
Wooded rural lots are the norm, so shading is the usual constraint on a roof array. Open acreage often makes ground-mount the better answer here.
Inland Colleton County, so salt is not the driver, but wind-load requirements and county structural review still apply. Standing-seam metal roofs are common and mount cleanly.
Largely rural with few HOAs, so placement is driven by the roof and the sun rather than by an architectural-review committee.
Rural distribution lines can be slower to restore after a storm, so backup has practical value beyond convenience here.
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 Colleton 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 Walterboro. 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 $24,605 claims $6,151 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.
One Walterboro design sized to your usage at the $2.59 per watt benchmark, with annual kWh and the 25% SC credit year by year.
6 approvals in Colleton County. We file all of them.
Standard structural attachment, then the Colleton 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.

Walterboro solar FAQ
Walterboro-area homes are served by Dominion Energy South Carolina or Edisto Electric Cooperative, depending on the address. We confirm yours during the assessment.
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 $2.59 per watt benchmark, a 6 kW system is about $15,540 installed and a 9.5 kW system about $24,605. South Carolina’s 25% state credit brings those to about $11,655 and $18,454, claimed at up to $3,500 a year. In Walterboro 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 Colleton County assessor.
50% of Walterboro 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.
Many Walterboro properties have no HOA, which can make design simpler. Where one applies, we handle the architectural-review paperwork for you.
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, which is common in Colleton County; An additional electrical permit where battery storage is included. We pull every one through Colleton County and book the inspections.
Your roof needs replacing within about five years. Your power bill is under roughly $90 a month. Your lot is heavily wooded and you have no open ground for a ground-mount alternative.

Yes. We install in Walterboro and across Colleton 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 Walterboro’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.
