What is the solar market in Greer like?
Greer is growing faster than any other city we track in South Carolina. The Census Bureau’s Vintage 2025 estimate puts it at 50,007 residents, up 7.3% in a year, split between Greenville County (35,669) and Spartanburg County (14,338).
The housing is young: the median home was built in 2002 and 72.4% of homes are owner-occupied, according to the 2023 American Community Survey. Newer roofs and owner-occupiers are the two conditions rooftop solar needs, which is why Greer draws so much door-to-door solar selling.
That selling has a local twist. In February 2026 Greer CPW warned customers about salespeople claiming to represent its net metering program, and said it would not typically knock on your door except in an emergency.
It also said it had not raised electric rates in 2026, contrary to what some sellers claimed. Any pitch built on rising Greer rates should show you where the number came from.
What do Greer CPW customers pay for electricity?
Greer CPW’s average residential price was 11.8¢ per kWh in 2024, by our calculation from EIA Form 861 (residential revenue divided by residential sales). Duke Energy Carolinas averaged 13.99¢ the same year. Lower prices mean each kilowatt-hour your panels replace saves a little less in Greer than on a Duke bill, which lengthens payback.
On the solar rate, energy is billed at 10.8828¢ per kWh for the first 1,000 kWh a month and 11.9861¢ above that, plus CPW’s purchased power adjustment and any taxes. A household that uses more than 1,000 kWh in summer saves at the higher tier first, because solar trims the top of the bill.
How much solar does a Greer home need?
Size from your CPW bills, not from roof area. Because exports earn 6.54¢ or 4.251¢ while your own use avoids about 10.9–12.0¢, an array that covers most of your daytime load and exports little tends to beat one sized to wipe out the whole annual bill.
CPW also caps size. Its interconnection agreement calculates the AC rating as installed DC capacity × 0.85, and that rating may not exceed 90% of your service rating; going over means you pay for the service upgrade.
A residential Tier 1 application covers systems of 20 kW or less. Run your own usage through the system size calculator.
How do you estimate solar savings on a Greer CPW bill?
Split your expected production in two. Solar you use as it is made is worth your marginal energy rate (10.88¢ or 11.99¢).
Solar you export is worth the credit for the hour it leaves the house: 6.54¢ during on-peak hours (1–9 p.m. weekdays June to September; 6 a.m.–1 p.m. weekdays October to May) and 4.251¢ at all other times, including weekends.
Those peak windows suit solar better than most utilities’ do. A summer weekday afternoon export and a winter weekday morning export both earn the higher credit.
Credits that exceed a month’s bill carry forward for up to 12 months, and the PMPA net billing agreement says unused credits are paid out at the end of each calendar year.
The $16.78 facilities charge is the minimum bill, so credits never take you below it. Use the savings calculator with these inputs, and see the worked examples on the Greer solar cost page.
What does solar cost in Greer?
We do not publish a Greer installed price or price per watt: our rule is twelve sourced, dated local quotes before printing one. What we can price are the fixed local costs. CPW charges a $100 non-refundable application fee for a Tier 1 system.
The City of Greer charges a building permit on a valuation table: $150 for the first $15,000 of construction value plus $5.50 for each further $1,000, plus a technology fee of 3% of the permit fee (minimum $4, maximum $100).
On an example $25,000 contract that is a $205.00 permit plus $6.15 technology fee. The full method, with three scenarios, is on solar cost in Greer; state context is on South Carolina solar cost.
Which incentives apply to solar in Greer?
The South Carolina solar energy credit (SC Code §12-6-3587) is the one that matters: 25% of what you paid to buy and install a system you own, claimed on Form TC-38, limited each year to the lesser of $3,500 or half your state tax liability, with up to 10 years to use the rest.
The federal §25D credit is not available for property placed in service after 31 December 2025.
We found no Greer CPW or City of Greer solar rebate. CPW’s incentive is the rate itself: on-peak export credits that line up with solar hours. Details and the full table are on solar incentives in Greer and the SC solar tax credit.
How does Greer CPW handle net metering?
Greer CPW calls it net metering; the paperwork is net billing. CPW buys all its wholesale power from PMPA, so excess solar is bought by PMPA under a three-way agreement between you, CPW and PMPA, and shows up as a credit on your CPW bill.
Your own use comes first; only power you do not consume counts as excess. CPW installs a meter that records both directions.
Because CPW is a municipal utility, the Solar Choice tariffs that Act 62 of 2019 created for Duke and Dominion do not set its terms.
CPW’s rate sheet ties the credits to PMPA’s wholesale rates, so they can change; ask CPW at 864-848-5500 for the current Rate 750 sheet before you sign.
If your bill comes from Duke Energy Carolinas instead, Duke’s Residential Solar Choice rider applies; see net metering in South Carolina.
How does a Greer solar installation get approved?
Use the CPW service map. Duke or a cooperative account means different rules.
Inside city limits, the City of Greer Planning & Development issues the permit through eTRAKiT. Outside, it is Greenville or Spartanburg County.
$100 fee, proof of IEEE 1547 and UL 1741 compliance, and a homeowner’s policy with at least $100,000 liability cover.
Code officials inspect first. CPW then checks the visible-break manual disconnect mounted beside the meter.
Tell CPW in writing at least ten business days before the in-service date; CPW may attend.
CPW sends written notice that parallel operation may begin within five business days of receiving your documents and seeing the switch work.
What else shapes a Greer install?
Roof and climate. Greenville County logged 84 hail reports from 2015 to 2025 in NOAA’s Storm Events Database, eight of them 2 inches or larger, with a largest stone of 2.5 inches, plus about 12 wind events a year.
Ask what hail rating the modules carry and whether your roof will outlast them; a 2002-era shingle roof may be due before the panels are. Installation steps in Greer.
Batteries. Rate 750 bills energy on flat tiers, so a battery mostly buys backup rather than bill savings. Battery storage in Greer.
Financing. CPW’s agreement allows leases and loans but forbids any arrangement where you buy electricity from a third party, matching state law. Financing in Greer.
Residential or commercial. Homes use code 750 and Tier 1; small businesses use code 704 and Tier 2 (100 kW or less, $250 fee, $300,000 liability cover). Commercial solar in Greer.
How do you choose a solar installer in Greer?
We do not rank or name Greer installers. These are the checks that matter here.
The proposal should use 6.54¢ and 4.251¢ exports, not Duke’s rider or full retail net metering.
Panel installation, roof attachment and wiring can need different SC LLR registrations. Verify each one yourself.
The $100 Tier 1 application, the insurance certificate and the ten-day in-service notice all need an owner.
CPW says it does not send solar sellers door to door. Call 864-848-5500 to check. You can cancel a door-to-door sale until midnight of the third business day.

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
- federal and state government sources
- 66
- researched pages published
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.
