Your utility is the city, and its rules are its own
The City of Concord operates its own municipal electric utility through the city's Electric Systems department. North Carolina has 76 municipally-owned electric utilities, and municipal electric providers and Electric Membership Cooperatives are not regulated by the North Carolina Utilities Commission, unlike investor-owned utilities.
The consequence is direct. Duke Energy's move away from legacy flat retail net metering for new residential customers, its time-differentiated rates and its bridge rate options are the subject of nearly every recent North Carolina solar article, and none of it governs a Concord Electric Systems customer. Applying a Duke payback figure here is not a small adjustment, it is the wrong utility.
Read the name on your electricity bill before anything else. Concord sits close enough to Duke territory that neighbouring towns operate under entirely different rules, so a recommendation from a friend a few miles away may be describing a different arrangement altogether.
It gives you a fair test of an installer, too. Someone who has worked in Concord will know that the city requires a pre-project approval meeting and will raise it unprompted. Someone who opens with Duke net metering savings has not done a project here.
The pre-project approval meeting comes first
The City of Concord requires a pre-project approval meeting before any interconnection paperwork can be submitted. That is a sequencing rule with teeth: paperwork filed ahead of the meeting is not a shortcut, it is a step out of order.
Used well, the requirement is an advantage rather than an obstacle. It puts you in front of the people who set the terms before you have signed a contract, ordered equipment or agreed an installation date, which is the one point in a solar project where questions are still cheap to ask.
Take a specific list into it. What metering arrangements are open to a residential customer at my address. What is paid for energy I export or produce, and is that rate fixed or does it move. Is there an interconnection or application fee, and when is it charged. Is there a size limit on a residential system. Is battery storage permitted under the arrangement I would be on.
Ask to attend even if your installer is arranging the meeting. The answers determine whether the system is worth buying, and hearing them first-hand from the utility is worth an hour of your time.
Buy-all sell-all, and what we could not confirm
Concord Electric Systems describes buy-all sell-all as a way for small scale renewable energy producers to connect back into the grid. It uses a two-meter arrangement, one meter measuring what you consume and the other measuring what you produce.
Understand what that structure implies before you evaluate any quote. Under a buy-all sell-all arrangement you are not offsetting your own consumption. Everything the array produces is sold to the utility, and everything your home uses is bought from the utility, so the two are settled separately rather than netted against each other. Advice about shifting laundry or vehicle charging into daylight hours, which is standard everywhere else, does not carry over to that structure.
What we did not confirm from the city's own published material is the rate Concord pays for produced energy, or whether other metering arrangements are also open to residential customers. Those two answers decide the economics completely, and we are not going to estimate them from what a neighbouring utility pays or from figures circulating on commercial solar sites.
So put both questions to Concord Electric Systems directly at the pre-project meeting, and ask for the answer in writing. For larger systems, note that for generating facilities above 20 kW residential the city determines whether the Fast Track Process or the Study Process applies, which affects how long approval takes.
The state benefit that stays, and the federal one that has gone
North Carolina excludes most of the added assessed home value of a residential active solar heating, cooling or electric system from property tax. That applies regardless of who supplies your electricity. The improvement does not raise your tax bill the way an equivalent renovation would, and because nothing has to be filed and no cheque arrives, most people leave it out of their own arithmetic.
The federal position has changed. 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 the resulting payback figure is wrong by a wide margin.
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 they offer you. What they claim and what reaches you are separate questions, so ask both and confirm with a tax advisor rather than with the sales material.
On permits, North Carolina requires both a building permit and an electrical permit from the local authority having jurisdiction. Confirm with the city what your address needs and agree in writing with your installer who files each one, since the common failure on a two-permit project is each party assuming the other handled one.
