You’ve seen the videos from Germany: a couple of solar panels clipped to an apartment railing, a cord running to an outlet in the living room, and a little app showing the fridge running on sunshine. It looks so simple that the obvious question comes next: is balcony solar legal in my state? In the U.S., the honest answer depends on where you live and, in most places, on your utility.

The short answer: as of October 2, 2026, ten states have passed laws that let you use a small, certified plug-in solar device without a utility interconnection agreement: Utah, Maryland, Maine, Virginia, Colorado, Connecticut, Vermont, New Hampshire, New Jersey and California. Several of them don’t take effect until 2027. Everywhere else, your utility’s interconnection rules apply, so ask the utility before connecting anything.

Below is what each law says, checked against state legislature, governor, regulator or utility pages; we left out anything found only on third-party trackers. This is general information, not legal advice. Confirm with your utility and your state before you buy.

What “legal” means for plug-in solar

A balcony or plug-in solar kit is one or two panels plus a small grid-tied microinverter that plugs into a regular 120 V outlet. Its power flows into your home’s wiring, where the fridge and router use it first, so you buy less from the grid. That makes it a small power plant on the utility grid, and utilities have rules for connecting those (an “interconnection agreement”), written for rooftop systems with permits and inspections.

The new state laws carve out a simpler path. Most say the device must stay under a watt limit (usually 1,200 W), be certified by a recognized testing lab such as UL, and shut off during an outage so it can’t put power on lines where crews are working. In exchange, the utility can’t demand approval, fees or extra equipment. Some laws add a utility notice, one device per meter, or rules for renters and HOAs.

Safety is why the details matter. UL Solutions, which began certifying plug-in systems in January 2026 under its UL 3700 outline, warns that grid current plus panel current can exceed a circuit’s wire rating without tripping the breaker, and that plug blades can be live in sunlight if the system isn’t designed to prevent it. Certified devices are built for those risks; uncertified imports may not be.

States where plug-in solar is allowed today

Utah

Utah went first. HB 340, signed March 25, 2025 and in effect since May 7, 2025, allows a movable “portable solar generation device” of up to 1,200 W on a standard 120 V outlet with no interconnection agreement. It must meet the latest National Electrical Code, be certified by UL or an equivalent lab and not energize the building’s wiring in an outage. Rocky Mountain Power’s page repeats those rules, says utilities may not require approval, fees or extra equipment, and notes that these devices are excluded from net metering, so power you don’t use at that moment earns no credit.

Maryland

Maryland’s Utility RELIEF Act (HB 1532, Chapter 353) was approved on May 12, 2026 as an emergency law, effective right away. According to the Maryland Public Service Commission, you may install one portable solar system per electric meter, residential only, supplying no more than 1,200 W and certified by UL or an equivalent lab. You must notify your electric company before installation, with a certification of the device’s safety features and maximum output. The utility can’t require approval or a fee, but if your device needs an automatic locking disconnect switch, you pay for it.

Maine

Maine’s LD 1730 (Public Law Chapter 644, approved April 6, 2026) uses tiers. You can install plug-in solar or plug-in battery systems totaling up to 420 W yourself. From 420 W to 1,200 W per service address, a Maine-licensed electrician must install each system on a dedicated circuit with a single outlet, and you notify the utility within 30 days. Systems must be listed to UL 3700 or a comparable standard (or configured to the electrical code), and inverters must shut off within 0.2 seconds when the grid fails. No net energy billing. Renters must not damage the building and must restore it afterward.

Vermont

Vermont’s Act 149 (S.202), signed June 16, 2026, took effect July 1, 2026. You may install plug-in devices up to 1,200 W of combined inverter capacity per meter, only where the home has a smart meter. Devices must be certified to UL 3700 or an equivalent, follow IEEE 1547-2018, shut off in an outage and be securely attached. No approval, fees or extra equipment can be required. The catches: exported power isn’t paid for, and you can’t have both a net-metered system and a plug-in device. Tenants must give the landlord 10 days’ notice; the landlord may set reasonable restrictions.

Colorado

Colorado’s HB26-1007, signed May 7, 2026, set the highest limit in the country: one system per address supplying no more than 1,920 W to the grid. The act’s text sets its start date at August 12, 2026 (barring a referendum petition). The device must be listed by a recognized testing lab and must not energize the grid in an outage, and only one device may go on a single outlet. Utilities can’t require approval, fees or extra equipment, but may ask you to report the device and its size. From January 1, 2027, unlisted devices over 391 W can’t be sold in Colorado, and landlords, HOAs and covenants can’t unreasonably ban plug-in solar, though owners may set reasonable restrictions (notice, location, fire safety). Fire and local building codes still apply.

Connecticut

Connecticut’s Public Act 26-127 (HB 5340), approved June 4, 2026, covers plug-in devices from October 1, 2026. A qualifying device is not permanently attached, puts out no more than 1,200 W through a standard 120 V outlet, meets the building code, the National Electrical Code and IEEE 1547, is certified to UL 1741 by UL or an equivalent lab, and won’t energize the house in an outage. One device per meter is exempt from interconnection. Note the warning the law requires: power beyond what you’re using at the moment will be charged to you as usage unless your meter allows net metering. Ask your utility about your meter first.

States where the law is signed but not in force yet

Virginia. HB 395 added Code of Virginia § 56-596.8, which takes effect January 1, 2027. It allows a movable device of up to 1,200 W per customer, or per apartment in multifamily housing, that meets the latest electrical code and is certified by a recognized lab. Before installing you notify the utility on a form set by the State Corporation Commission; if the utility doesn’t respond within 15 days, the notice counts as complete. Landlords who own more than four rental units can’t forbid a tenant from installing one on the outside of their unit.

New Hampshire. Governor Kelly Ayotte signed SB 540 in July 2026. The bill text caps devices at 1,200 W of AC inverter output and exempts them from interconnection and net metering. But the City of Dover explains that part of the law starts January 1, 2027 and that actually using these systems won’t be legal until the state Department of Energy certifies that a national electrical standard exists and building codes are updated. Dover’s energy commission and electrical inspector advise residents to wait before buying.

New Jersey. Governor Mikie Sherrill signed the Garden State Balcony Solar Act (S2368/A4836) on September 1, 2026. Her office says it exempts plug-in devices of up to 1,200 W from utility interconnection and metering requirements, fees, approvals and equipment mandates, stops landlords and homeowner associations from broadly prohibiting them, and bars towns from banning them or requiring permits. News reports of the bill give a start date of March 1, 2027; wait for the state’s go-ahead.

California. Governor Gavin Newsom signed SB 868 (portable solar generation devices) on September 30, 2026, according to his office’s legislative update. The legislature’s bill page describes a limit of 1,200 W of combined AC output per dwelling and an exemption from interconnection rules. California’s rules aren’t in force yet; watch for guidance from the California Public Utilities Commission and your utility.

New York is close but not there. The New York Senate says the Legislature passed the SUNNY Act on May 28, 2026. At our last check it was still waiting for Governor Kathy Hochul’s signature. Until it’s signed and in effect, New York utilities’ interconnection rules apply.

What if your state has no plug-in solar law?

Then a grid-tied plug-in kit is treated like any other grid-connected solar system: usually an interconnection application to your utility, and often a permit and inspection. Some sellers call their kits “legal in all 50 states”; that’s the seller’s claim, not something any state has said. Don’t plug a grid-tied kit into an outlet unless your utility has approved it in writing. Beyond the rules, an uncertified setup can overload a circuit or put power on the line during an outage.

You still have good options that need no permission at all:

• Portable panels with a power station. The panels charge a battery, and you plug devices into the battery. Nothing connects to your home’s wiring, so no utility rules apply. It’s the same setup campers use, and it doubles as outage backup. See our best solar generators guide.
• Community solar. In states with programs, you subscribe to part of a solar farm and get credits on your bill. More in our guide to solar panels for renters.
• Ask your utility whether it has a simple process for small systems.

Kits that follow the new laws

Prices change often. The prices below are what we saw at the maker in October 2026; check the current price before you buy.

Few plug-in kits are sold in the U.S. so far. We quote each maker’s words; your state’s law and your utility have the final say. Our best balcony solar kits guide compares more.

EcoFlow STREAM. EcoFlow’s product pages say plug-in installation of the STREAM Microinverter and STREAM Ultra “is currently permitted in Utah, Maryland and Colorado,” and the same pages note that, under Utah’s HB 340, plug-and-play installation is only available in Utah. Elsewhere, follow your utility’s rules.

A power station with a panel works in any state or rental today, because it never connects to your home’s wiring. The Jackery Solar Generator 1000 v2 pairs a 1,070 Wh LiFePO4 station (1,500 W AC) with a 200 W folding panel. It won’t cut your bill much, but it keeps phones, lights and a fridge going in an outage.

Before you buy: a five-step check

1. Find your state’s status in the table above, and check the date: a signed law may not be in force yet.
2. Call or check your utility. Ask whether it needs a notice (Maryland and Virginia do; Maine above 420 W), whether you need a smart meter (Vermont), and what happens to power you send back.
3. Buy only certified equipment under your state’s watt limit, and keep the certificate. Several laws require a UL or equivalent listing, and some name UL 3700.
4. Get the landlord’s or HOA’s OK in writing, unless your state’s law protects you, and even then follow the notice rules (Vermont, Colorado, Virginia and New Jersey address renters or HOAs).
5. Use a sound outlet and circuit, follow the maker’s instructions, and if you’re unsure about your wiring, have a licensed electrician check it.

Balcony solar legal questions

Is balcony solar legal in the USA?

In some states. As of October 2, 2026, ten states have plug-in solar laws: Utah, Maryland, Maine, Vermont, Colorado and Connecticut have them in force, while Virginia, New Hampshire, New Jersey and California have signed laws that start later. New York’s bill awaits the governor. Elsewhere, utility interconnection rules apply.

Can a renter install balcony solar?

Often, with the landlord’s agreement. Vermont requires 10 days’ notice to the landlord, who may set reasonable restrictions. Virginia stops landlords with more than four units from forbidding exterior installs, and Colorado and New Jersey limit blanket bans by landlords or HOAs. Everywhere else, get written permission first and use mounts that leave no damage.

Do I get paid for the power I send to the grid?

Usually not. Utah, Maine and Vermont keep plug-in devices out of net metering, Vermont says exported power isn’t compensated, and Connecticut warns excess power may be billed as usage unless your meter allows net metering. Size your kit to what your home uses during the day, not to the maximum allowed.

Is there a tax credit for balcony solar in 2026?

No federal one. The 30% residential clean energy credit (25D) ended for systems installed after December 31, 2025. A few states and utilities have their own programs, so check DSIRE and your utility’s rebate page, but don’t count on money for a plug-in kit.
