What moves the price of a North Charleston system?
Five things set what a North Charleston homeowner actually pays. System size, set by your usage and capped at 20 kW AC by both local utilities.
Roof condition, in a city whose median home was built in 1995, so many roofs are due a replacement within a typical solar loan term.
Electrical capacity, because a service upgrade is billed by the City at $0.25 per amp on top of the contractor’s own price. Storage, if you add a battery to work Dominion’s on-peak window. And financing, where dealer fees can sit inside the cash price.
Equipment brand matters less than these in the final number. Ask every installer to break the quote into equipment, labour, permitting, any roof or electrical work, and financing charges, so the lines can be compared across quotes.
North Charleston City permit fees by example contract value
| Example contract | Building fee | Plan check | Two $30 filing fees | Electrical alteration | Total |
|---|---|---|---|---|---|
| $12,000 | $70 | $35.00 | $60 | $30 | $195.00 |
| $20,000 | $110 | $55.00 | $60 | $30 | $255.00 |
| $28,000 | $150 | $75.00 | $60 | $30 | $315.00 |
| $36,000 | $190 | $95.00 | $60 | $30 | $375.00 |
| $48,000 | $250 | $125.00 | $60 | $30 | $465.00 |
HyreSolar arithmetic on the City of North Charleston permit fee schedule, retrieved 5 October 2026.
We assume the electrical tie-in is billed as an alteration ($30); if the job includes a new or upgraded service, the City charges $0.25 per amp instead (a 200-amp service is $50). Contract values are examples.
Above $50,000 the building fee becomes $260 plus $4 per further $1,000.
Should you compare North Charleston quotes on cost per watt?
Yes, as a check, not a target. Divide each quote’s total before incentives by the system’s DC watts to compare quotes of different sizes on one basis, then look for the reasons a quote is high or low: a battery, a re-roof, a panel upgrade, or a financed price with a dealer fee folded in.
We do not print a North Charleston benchmark for the reason above; how cost per watt works explains the method.
Local add-on costs a North Charleston quote may carry
| Item | When it applies in North Charleston | What sets the cost |
|---|---|---|
| Re-roof before install | Shingles near the end of life on a pre-1995 home | Roof size and material; prices separately from the solar contract |
| Service or panel upgrade | Older 100–150 A panels; adding a battery or EV charger | Contractor price plus City electrical fee of $0.25/amp |
| Elevation certificate | Homes in a special flood hazard area where the City asks for one | A licensed SC engineer or surveyor |
| Battery | Dominion customers working the on-peak window; outage backup | Usable kWh and backup scope |
| Berkeley Electric fees | Co-op members only | $150 application + $50 inspection |

How we calculate net cost and payback for North Charleston
Gross cost is the contract price plus City fees and any utility fees.
Incentives are the SC credit: 25% of the cost of a system you own, used at up to $3,500 a year or half your state tax liability, whichever is less, for up to 10 years.
There is no federal homeowner credit for systems placed in service after 31 December 2025. Financing cost is the interest and fees on any loan.
Net cost is gross cost plus financing cost minus the credit you can actually use.
Savings depend on your utility. On Dominion, solar you use at midday displaces off-peak energy at 15.074¢, and surplus can offset only lower-priced periods before it banks to a November cash-out at avoided cost.
On Berkeley Electric, self-used solar displaces the co-op’s retail price (14.93¢ average in 2024) and exports earn 6.03¢. Neither touches the fixed monthly charges.
Three North Charleston scenarios on example inputs
| Scenario | Example size / contract | Example annual output | SC credit (years to use at cap) | Year-one value on Dominion | Year-one value on Berkeley Electric |
|---|---|---|---|---|---|
| Small | 5 kW / $16,000 | 6,500 kWh, 60% used on site | $4,000 (2 yr) | $838 | $739 |
| Medium | 8 kW / $25,000 | 10,400 kWh, 55% used on site | $6,250 (2 yr) | $1,313 | $1,136 |
| Large | 11 kW / $34,000 | 14,300 kWh, 50% used on site | $8,500 (3 yr) | $1,766 | $1,499 |
Every input is an example chosen to show the arithmetic: not a North Charleston price, not a production forecast for your roof.
Dominion value = on-site kWh × 15.074¢ off-peak + exported kWh × 9.623¢ super off-peak (a floor). Berkeley value = on-site kWh × 14.93¢ average + exported kWh × 6.03¢. Before the minimum bill, taxes and riders.
Simple payback on the medium example, cash, Dominion: ($25,000 + $292.50 City fees − $6,250 credit) ÷ $1,313 a year ≈ 14.5 years, before rate changes and panel degradation. Run your own numbers in the savings calculator and payback calculator.
How Dominion and Berkeley Electric rates change North Charleston savings
The same roof is worth different amounts on the two utilities because the export credit differs and so does the time pattern.
On Dominion, moving a load such as a pool pump or water heater into the midday solar window raises the share used on site, which is the cheapest gain available.
On Berkeley Electric, exports at 6.03¢ are worth about 40% of retail, so the same shift pays as well.
Rate rises raise the value of every kWh you avoid buying; we do not assume an escalator in the scenarios above. If a quote shows a high annual price increase, ask where the figure comes from; our escalator calculator shows how much it inflates a 25-year saving.

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.
- 160
- primary sources read and cited
- 228
- figures with a retrieval date

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.
