What determines solar cost in Greer?
Five things set what a Greer homeowner pays: system size, equipment, labour and overhead, the fixed local fees, and any roof or electrical work the house needs first. Only the fees are public. The rest comes from quotes, so compare at least three and read how to compare Greer installers.
Greer adds two local twists. Greer CPW caps the AC rating (DC × 0.85) at 90% of your service rating and charges you for any upgrade beyond that, so a smaller service can raise the cost of a larger array.
And because Greer CPW averaged 11.8¢ per kWh for homes in 2024 against 13.99¢ on Duke Energy Carolinas (EIA-861), the same system saves somewhat less in Greer than a few miles away on Duke.
Greer permit and CPW fees at three contract values
| If your contract is | City permit fee | 3% technology fee | CPW Tier 1 fee | Total |
|---|---|---|---|---|
| $18,000 contract (example) | $166.50 | $5.00 | $100.00 | $271.50 |
| $25,000 contract (example) | $205.00 | $6.15 | $100.00 | $311.15 |
| $35,000 contract (example) | $260.00 | $7.80 | $100.00 | $367.80 |

Unincorporated addresses are permitted by Greenville or Spartanburg County on their own fee tables. A re-inspection is $50 in the City. Ask whether a separate electrical permit applies to your job.
What system size suits a Greer home, and how does size change cost?
Size follows your CPW usage. Each kWh you use yourself is worth your energy rate (10.88¢ for the first 1,000 kWh a month, 11.99¢ above), so the economics favour covering daytime use rather than producing a big surplus. Residential Tier 1 tops out at 20 kW.
Price per watt is the usual way to compare quotes of different sizes, and larger systems usually spread fixed costs further. We do not quote a Greer price per watt; use how cost per watt works to compare yours.
Which extra costs show up on Greer solar projects?
Roof work. Greer’s median home dates from 2002, so many roofs will need replacing within the array’s life. Removing and reinstalling panels later is a cost to price now. Greenville County had eight hail reports of 2 inches or more from 2015 to 2025 in NOAA records.
Electrical upgrades. If the array’s AC rating would exceed 90% of your service rating, CPW’s agreement makes you pay for the upgrade. Get that line in writing.
Hidden extras. The visible-break disconnect beside the meter, the insurance certificate CPW requires (at least $100,000 liability), and permit re-inspections. Batteries add a large line item and, on Rate 750, mostly buy backup; see battery storage in Greer.
How do you work out net cost and payback for a Greer system?
The contract price, including permit and CPW fees.
25% of the cost of a system you own, claimed on Form TC-38, at most $3,500 a year and half your state liability, carried forward up to 10 years.
Interest and any dealer fee. See solar financing in Greer.
Self-used kWh × your CPW energy rate, plus exported kWh × 6.54¢ (on-peak) or 4.251¢ (off-peak).
Net cost ÷ annual savings. This ignores rate changes, degradation and maintenance, which is why it is a floor for comparison, not a forecast.
Three worked Greer scenarios (example inputs)
| Scenario | Example size | Example contract | SC credit | Net cost | Year-one savings | Simple payback |
|---|---|---|---|---|---|---|
| Small | 5 kW DC | $15,000 | $3,750 over 2 yrs | $11,250 | $565 | 19.9 years |
| Medium | 8 kW DC | $24,000 | $6,000 over 2 yrs | $18,000 | $904 | 19.9 years |
| Large | 11 kW DC | $33,000 | $8,250 over 3 yrs | $24,750 | $1,242 | 19.9 years |
Example inputs, not Greer prices or measured output: 1,300 kWh per kW DC a year, 60% of output used in the home, exports split 50/50 on-peak/off-peak, energy at the first-tier Rate 750 price.
Credits from the Greer CPW Rate 750 sheet, retrieved 5 October 2026. Excludes the purchased power adjustment, financing, degradation and rate changes. Assumes enough state tax liability to use the credit.
How do Greer CPW rates change the savings?
Two levers move the numbers above more than anything else. The first is how much you use yourself: raising the self-use share in the medium example from 60% to 80% adds about $114 a year, because each kWh shifted from export to self-use gains the gap between the energy rate and the credit.
The second is the credit itself: CPW’s rate sheet ties both credits to PMPA wholesale rates, so they can move up or down.
CPW said in February 2026 that it had not raised electric rates in 2026. A proposal that assumes steep annual rate increases should say where the figure came from. Run your own numbers in the savings calculator or the payback calculator; compare state context on South Carolina solar cost.
How should you compare solar quotes in Greer?
Line them up on the same basis: DC and AC size, equipment, total price with and without financing, and a savings estimate that uses CPW’s Rate 750 values.
A quote that credits exports at the full retail rate, or models Duke Energy’s rider, overstates savings for a CPW home.
Check that the City or county permit, the $100 CPW fee and the disconnect switch are included, and that the quote does not count a federal credit. Incentive details are on solar incentives in Greer.

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
- 115

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.
