Panels on the roof are not a working system
Winston-Salem puts it plainly: your PV system must be inspected and approved by a licensed electrical inspector and utility before it can operate. The City's Inspections Division handles solar project electrical permits and can be reached on 336-727-2624.
Those are two separate approvals from two separate organisations. The city inspection is one gate. Utility approval is another, and it runs on the utility's timetable rather than your installer's. An installer can be entirely diligent and your system can still sit idle waiting for the second.
So ask the question that matters before you sign: what is your typical time from installation complete to permission to operate in Winston-Salem, and what have the last few projects actually taken. An installer who works here regularly knows the answer. One who quotes only an installation date is quoting the easy half.
It also changes how you read a payment schedule. If a contract treats installation as substantial completion, understand that you may be paying in full for a system that cannot legally run yet. That is not necessarily unreasonable, but it should be a decision you made rather than one you discovered.
The city publishes a buying checklist, and it is a good one
Winston-Salem's guidance to homeowners is unusually practical. It advises shopping around to compare prices before choosing a PV contractor, and obtaining two to three estimates from different contractors to compare pricing and PV systems.
It also tells you to check contractors with the local Office of Consumer Affairs, and to verify that the contractor provides a written contract that includes equipment pricing, installation costs, model numbers and warranty information. Model numbers are the item most often left out, and they are what turn a warranty into something you can actually enforce.
The sharpest item on the list is the one about warranties: make sure you know who is responsible for honoring the warranty. On a solar installation that can be three different parties for the panels, the inverter and the workmanship, and a company that has left the market cannot honour any of them. Ask which obligations sit with the manufacturer and which sit with the installer.
Contractors must be licensed by the state of North Carolina performing work within the scope of their license, and the city notes that the PV contractor assists with obtaining all building permits and inspections. Verify the licence rather than assuming it, and agree in writing which filings the contractor is handling.
Your association, and where the panels should go
The city's guidance includes a reminder worth taking seriously: if you live in a homeowners association, verify that you have all required approvals from the Architectural Review Committee as applicable. Approval from the city says nothing about approval from your association, and the two run independently.
Submit a specific application to the committee rather than a general request. Layout, mounting method, panel and frame colour and the route of any visible conduit remove most of the uncertainty a committee is actually reacting to. North Carolina law also limits how far an association can go in restricting solar, which is worth knowing before a conversation becomes an argument.
On siting, the city's advice matches the physics. Systems should be installed on a southern exposed roof, ideally mounted parallel with the roof at a 15 to 45 degree roof pitch, with no shading between the hours of 9 a.m. and 4 p.m.
Use that window as a test rather than a decoration. Ask your installer to demonstrate shading across 9 a.m. to 4 p.m. through the year, not just on the day they visited, because a tree that clears the roof in July may not in October. Check the roof covering's age at the same time, since panels outlast most coverings and one near replacement should be replaced first.
What changed recently, and what a stale quote misses
Winston-Salem is served by Duke Energy, and Duke Energy no longer offers legacy flat retail net metering to new residential solar customers. New customers are placed on time-differentiated net-metering or bridge rate options, so what your generation is worth depends on when it happens rather than only on the annual total.
That interacts with the city's siting advice in a useful way. Under flat retail crediting the only question was how much you produced. Under time-differentiated rates, when you produce and when you consume both matter, so a household that is empty from 9 a.m. to 4 p.m. is in a different position from one that is not.
The federal position has changed as well. The 30 percent residential tax credit under Section 25D applied through December 31, 2025 and is not available for a purchased home system placed in service after that date. A quote that still applies it is describing an earlier year, and combined with the utility change a published payback figure can be wrong twice over.
If you take a lease or a power purchase agreement rather than buying, the provider may claim the business version of the credit under Section 48E and reflect part of that value in the rate offered, so ask what they claim and what reaches you and confirm with a tax advisor. North Carolina's exclusion of most of the added assessed value of a residential solar system from property tax still applies and requires no application.
