What determines what solar costs in Summerville
Five things move a Summerville price. System size, which Berkeley Electric caps at your annual kWh ÷ 1,800 (and both utilities at 20 kW AC).
Roof condition, which matters because the median house in town dates from 2001 and may still have its first shingles.
Wind design, since Dorchester County logged 19.18 damaging wind events a year from 2015 to 2025 and attachments are engineered for it. Whether you need an electrical service upgrade.
And whether you add a battery, which earns more on Dominion’s Rate 5 than on the co-op.
Equipment and labour are where quotes differ most, and they are the part we cannot price for you. Compare them line by line using how cost per watt works and the proposal analyzer, rather than against a national average.
Town of Summerville solar permit fees by contract value
The Town values a renovation at its contract amount, so the building permit scales with your price. Solar needs a building and an electrical permit.
| Contract value | Building permit | Plan review (½) | Electrical permit | Admin ($30 × 2) | Total |
|---|---|---|---|---|---|
| $15,000 example contract | $120 | $60 | $30 | $60 | $270 |
| $25,000 example contract | $170 | $85 | $30 | $60 | $345 |
| $35,000 example contract | $220 | $110 | $30 | $60 | $420 |
HyreSolar arithmetic on the Town of Summerville Schedule of Permit Fees: $50 for the first $1,000 plus $5 per further $1,000 or fraction up to $50,000. The electrical permit is the $30 issuing fee; a new or upgraded service adds $0.25 per amp. Contract values are examples, not Summerville prices.
Work started before the permit is issued pays double fees, and a re-inspection after two failures for the same defect costs $150.
Interconnection and rate costs on each Summerville utility
Berkeley Electric Cooperative: $150 application fee and $50 inspection under the Renewable Surplus Rider, which is not available with time-of-day or demand rates. Exports earn 6.03¢/kWh, a figure the co-op revisits each year around 1 March.
Dominion Energy South Carolina: Solar Choice requires Rate 5, whose facilities charge is $0.4274/day against $0.36164/day on standard Rate 8, roughly $24 more a year before any energy is used.
Export credits never offset that charge, and the minimum bill is $13.50. Those are real costs of going solar on Dominion that a proposal should include.
Roof, electrical and battery costs a Summerville quote may add
A roof replacement before installation is the largest possible add-on. If your shingles date from the house’s construction, get a roofer’s opinion first: removing and reinstalling panels later is a separate job (removal and reinstall).
A main-panel or service upgrade adds both the electrician’s price and the Town’s $0.25 per amp electrical fee. A battery is priced separately; whether it pays depends on your utility, covered on the Summerville battery page.
Three Summerville cost scenarios, every input shown
The Summerville scenarios below are arithmetic for a Berkeley Electric member. Their contract prices and output figures are invented inputs to show the method, not quotes.
| Example system | Example contract | Town fees | SC credit (25%) | Net cost | Year-1 value (example) | Simple payback |
|---|---|---|---|---|---|---|
| Small: 5 kW | $15,000 | $270 | $3,750 over 2 yrs at the $3,500 cap | $11,520 | $739 | 15.6 yrs |
| Medium: 8 kW | $24,000 | $337.50 | $6,000 over 2 yrs at the $3,500 cap | $18,337.50 | $1,182 | 15.5 yrs |
| Large: 11 kW | $33,000 | $405 | $8,250 over 3 yrs at the $3,500 cap | $25,155 | $1,626 | 15.5 yrs |
Assumptions: 60% of output used on site, valued at Berkeley Electric’s 2024 average residential price of 14.93¢/kWh (EIA-861, which blends fixed and energy charges); the rest exported at 6.03¢/kWh.
Excludes the co-op’s $200 fees, financing, degradation and rate changes. The credit assumes your state tax liability is at least $7,000 a year; with less, it takes longer.
For a Dominion home the method is the same but the value of self-use follows the Rate 5 hour it replaces, and surplus is netted by period and cashed out each November at avoided cost. Run your own numbers in the savings calculator and payback calculator.
Gross cost, credit, financing and net cost: keep them separate
Gross cost is the contract price plus the Town and utility fees.
The South Carolina credit under SC Code §12-6-3587 is 25% of the purchase and installation cost of a system you own, claimed on Form TC-38 at no more than $3,500 or half your state tax a year, with up to ten years to use the rest.
On the medium example, a $6,000 credit takes two years even at the cap. Financing cost is the interest and any dealer fee on top. Net cost is what remains after the credit, and only then does savings arithmetic start.
A proposal that subtracts the whole credit on day one, or adds the ended federal credit, overstates the deal.

How Summerville electricity rates change the savings
On Dominion, panels produce mostly between late morning and mid-afternoon, which falls in Rate 5’s off-peak window at 15.074¢ in summer.
They do little against the 29.907¢ peak from 4 to 8 p.m. A household that can run its dishwasher, laundry and pool pump at midday captures more value from the same array.
On Berkeley Electric the gap that matters is between the price you pay and the 6.03¢ export credit, so the same advice holds: use the power while the sun is up.
Neither utility’s future rates are known. Treat any escalator a salesperson applies as an assumption, and ask to see the savings at zero escalation as well.

Primary-source research, data analysis and fact checking
We are a research desk, not a sales floor. We read the statute, the tariff, the code section, the federal filing or the manufacturer data sheet ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. That rule has cost us whole sections, and it is why the rest can be checked.

How this desk works
- Primary sources only. Statutes from the legislature’s own publishing system, federal data from the agency that collects it, code text from the adopted edition, manufacturer claims from the data sheet. We do not cite an article that cites a source; we go and read the source.
- Every figure carries its provenance. A named document and the date we retrieved it, so you can check it and so you know how old it is. Retrieval dates are not decoration: an EIA rate from May is a different fact from an EIA rate from August.
- We publish what we could not verify. Every research page carries a section naming the things we tried to establish and could not, and why. A paywalled standard, a state website that refused the request, a manufacturer that publishes no figure at all.
- We separate measurement from modeling from our own reasoning, and label which is which on the page. A laboratory measurement, an assumption inside a modeling tool and our own inference are three different kinds of claim and they are never presented as one.
- We do not sell solar, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Data as of Last verified 5 October 2026. Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
