New to plug-in solar?

Plug-in solar lets anyone generate free electricity — no roof, no permit, no contractor. A single panel on your balcony can meaningfully cut your bill, especially as rates keep rising.

Coming Soon — North Carolina is considering plug-in solar legislation

'Balcony Solar' would authorize portable solar devices up to 1,200W connected via a standard 120V outlet, add renter-rights protections (GS 42-42.4), and bar utility fees or interconnection agreements — though it would still require a standardized 15-day advance notice to the utility before operating the device.

Solar you can use in North Carolina today, while you wait

Plug-in solar that ties into your home's wiring isn't legal here yet — but a portable solar generator (a panel charging a battery you plug devices into directly) never touches your home's wiring, so it's legal everywhere, including North Carolina, right now.

Pending bill information may change as legislation advances. Bill text, watt caps, and effective dates are subject to amendment or failure. This is not legal advice.

What to Expect If This Passes

🔌

Up to 1200W, no permit

The bill as drafted would allow systems up to 1200W AC connected to a standard household outlet — no permit, no utility approval required.

⚡

No net metering

The bill does not include net metering for plug-in systems. Excess generation would not be credited. Self-consumption maximization is key.

🏠

Renters included

The bill does not restrict installation to homeowners. Renters would still need landlord consent, but no permanent installation is required.

ℹPanels typically last 25–30 years with a 25-year output warranty. Microinverters carry a 10–25 year warranty depending on brand. Battery modules degrade faster — expect 10–15 years before capacity drops below 80%. The 25-year savings figure above assumes the panel and inverter run for the full window; budget ~$200–$400 for an inverter swap around year 15 if needed.

Frequently Asked Questions

Can an HOA in North Carolina ban solar panels?
No. Under NCGS 22B-20 and a 2022 NC Supreme Court ruling, HOAs cannot effectively prohibit solar collectors, though they can impose reasonable restrictions on placement and appearance.
Is there a balcony solar bill in North Carolina?
Yes - House Bill 1129 ('Balcony Solar'), introduced in April 2026, would address plug-in solar devices, but as of mid-2026 it remains in the Rules Committee and has not passed.
Does Duke Energy require interconnection approval for tiny plug-in solar devices?
Under current rules, yes - any grid-tied system needs a Pre-Application and Interconnection Request with associated fees, regardless of wattage, unless HB 1129 changes this.
What happens to Duke Energy's net metering after 2026?
Duke's favorable Net Metering 'Bridge Rate' closes to new applicants on December 31, 2026, after which new solar customers move to a Time-of-Use rate structure.
