Solar Installers in Greer, SC

What is the solar installer market like in Greer?

Greer is a target for solar sales because it is growing fast and its homes are newer than most.

The city gained 7.3% in population between 2024 and 2025 (Census Vintage 2025), and its median home was built in 2002.

That combination brings in national sales companies, regional installers from Greenville and Spartanburg, and electricians who add solar as a sideline.

The selling has gone wrong often enough for the utility to step in.

Greer CPW’s February 2026 notice said salespeople claiming to represent its net metering program were going door to door, and that some claimed CPW had raised electric rates in 2026.

CPW said it had not. If a seller says they work with CPW, call 864-848-5500 and ask.

Which kinds of installers work in Greer?

You will meet three kinds. Direct installers sell, design and install with their own crews.

Sales-only dealers sign the contract and hand the work to a subcontractor, so ask who will actually be on your roof and who answers for the workmanship.

Electrical contractors may install solar alongside service upgrades, which can help where CPW’s 90% service-rating limit means your panel or service needs work first.

None of these is better by default. What matters in Greer is whether the company has done CPW interconnections before, because CPW’s paperwork runs through PMPA and differs from the Duke process most Upstate installers know best.

What should a qualified Greer installer handle for you?

A complete job in Greer covers six things: a design sized to your CPW bills, the building permit from the City of Greer through eTRAKiT (or from Greenville or Spartanburg County if you live outside city limits), equipment that meets IEEE 1547 and UL 1741 as CPW’s application requires, the CPW Tier 1 application and $100 fee, a code inspection, and a visible-break manual disconnect mounted on an outside wall next to the meter but separate from the meter socket.

Ask, too, who sends CPW the written notice at least ten business days before the system goes into service. CPW can attend on the day, and it will not give written permission to operate until it has the inspection paperwork and has seen the disconnect switch work. The full Greer installation sequence.

How do Greer installers size and price a system?

A good proposal starts from twelve months of your CPW usage. Under Rate 750, power you use yourself avoids 10.88¢ or more per kWh, while exports earn 6.54¢ on-peak or 4.251¢ off-peak.

An installer who sizes to cover 100% of your annual use will push more of your output into exports at the lower value. Ask to see the split between self-used and exported energy, and the credit rate applied to each.

CPW also limits the size: the AC rating, calculated as DC capacity × 0.85, may not exceed 90% of your service rating.

Pricing is usually quoted per watt or as a total; we do not publish a Greer price because we do not yet have twelve dated local quotes.

Compare quotes against each other with the proposal analyzer and read solar cost in Greer for the fixed local fees.

What should you ask a Greer installer before signing?

Ask how many Greer CPW interconnections the company has completed and how long the last one took from application to CPW’s written go-ahead. Ask who inside the company deals with CPW.

Ask what export credit the savings estimate uses and where it came from; the answer should be CPW’s Rate 750 sheet.

Ask what happens to the savings estimate if PMPA changes the credit, since CPW’s rate sheet ties both credits to PMPA wholesale rates.

Ask whether your roof will outlast the array. Greenville County had eight hail reports of 2 inches or more from 2015 to 2025 in NOAA records, and a roof from the early 2000s may need replacing during the panels’ life.

Removing and reinstalling an array costs real money, so get that price in writing. Also ask the company whether you should tell your home insurer before installation, as CPW suggests.

Which licences should a Greer solar installer hold?

South Carolina splits solar work between licences, and Greer has no separate local solar licence that we found.

"Solar Panel Installer" is a Residential Specialty registration with the Residential Builders Commission (SC LLR): fabricating, assembling, installing and replacing panels and related components. On its own that does not cover roof mounting.

Roof mounting: a Residential Builder, a Residential Specialty Contractor with the Roofer classification, or a General Contractor with a roofing classification. Wiring and connection: a Residential Builder, a licensed residential electrician, or a mechanical contractor with the electrical classification.

Check each name and number on the SC Labor, Licensing and Regulation lookup yourself.

Insurance runs two ways in Greer. The installer should carry its own liability and workers’ compensation cover.

Separately, CPW requires you, the homeowner, to keep a homeowner’s policy with at least $100,000 of liability cover per occurrence for as long as the system is connected, and to give CPW a certificate showing it. How to verify a licence.

What warranties and equipment should Greer quotes include?

Expect three separate warranties: the panel maker’s product and performance warranty, the inverter maker’s warranty, and the installer’s workmanship warranty covering roof penetrations and wiring.

The workmanship warranty is the one that matters if the company leaves the market, which is why the company’s track record in the Upstate matters more than the panel brand. Workmanship warranties explained.

For equipment, CPW’s requirement is specific: a utility-interactive inverter listed to UL 1741 that stops exporting when the grid goes down. Microinverters, string inverters and optimisers all qualify if listed.

Batteries are optional; on Rate 750 they are mainly a backup purchase, covered on battery storage in Greer. Financing options are on solar financing in Greer.
