It’s a Saturday morning in June. The sun is already hitting the railing of your apartment balcony, the fridge is humming inside, and you’re wondering why all that light can’t knock a few dollars off the power bill. In Germany, millions of people hang a couple of panels on the railing and plug them into an outlet. In the US, balcony solar (also called plug-in solar) is just arriving, state by state.

The best balcony solar kit for most US homes in a state that allows it is the EcoFlow STREAM Microinverter with two or three rigid panels: 1,200 W at 120 V, UL 1741 listed, 10-year warranty, about $369 before panels. If you want to store midday sun for the evening, the EcoFlow STREAM Ultra adds a 1.92 kWh battery. If your state or utility doesn’t allow plug-in solar yet, a power station charged by balcony panels is legal everywhere because it never connects to your house wiring.

Below: seven options, five grid-tied plug-in kits and two off-grid alternatives, with their real specs, what each maker says about where they may be used, and an honest estimate of what they produce. We researched and compared them from maker pages, state laws and published data; we did not test them.

Prices change often. The prices below are what we saw at the maker or a major retailer in October 2026; check the current price before you buy. Several plug-in kits were sold out when we checked.

First: is balcony solar legal where you live?

Check this before you spend anything. A plug-in kit pushes power back through a wall outlet, and in most of the US that still counts as connecting a generator to the grid, which needs your utility’s permission. A few states have passed laws that carve out small plug-in systems:

• Utah (HB 340, in effect since May 7, 2025): devices up to 1,200 W on a standard 120 V outlet, no interconnection agreement, but they must meet the electrical code, be UL (or equivalent lab) certified and must not energize the house during an outage.
• Maryland (HB 1532, signed May 12, 2026): up to 1,200 W; the Public Service Commission says to tell your utility before you install.
• Maine (LD 1730, in effect) and Virginia (HB 395, from January 1, 2027): up to 1,200 W. In Maine, systems over 420 W need a licensed electrician and a utility notice.
• Colorado (HB26-1007, up to 1,920 W) took effect August 12, 2026; its landlord, HOA and sales rules start January 1, 2027. California (SB 868, up to 1,200 W) was signed September 30, 2026 and is not in effect yet. Vermont and Connecticut also have laws in force, and New Hampshire and New Jersey have signed laws not yet in use: see our state-by-state guide.
• New York‘s SUNNY Act passed the legislature in May 2026 and was waiting for the governor’s signature when we checked.

Everywhere else, your utility’s interconnection rules apply, and some other states have bills moving. Never plug a solar panel into an outlet against your utility’s rules: ask the utility first. Our is balcony solar legal guide tracks the details state by state, and renters should also check the lease (Virginia’s and Colorado’s laws include renter or HOA protections).

The best balcony solar kits

1. EcoFlow STREAM Microinverter: best overall

The STREAM Microinverter is the box that turns panel power into 120 V household power and sends it through a standard outlet. It’s rated 1,200 W nominal (10 A), with four pairs of panel terminals on three MPPT trackers, up to 450 W per tracker and 1,200 W of panels in total. It works with third-party panels that use MC4 connectors and run between 16 and 60 V. EcoFlow lists UL 1741 certification with anti-islanding protection, which means it stops sending power when the grid goes down, so it can’t energize lines a utility worker is repairing. It’s NEMA 6 water-resistant and carries a 10-year warranty. EcoFlow’s page says plug-in installation “is currently permitted in Utah, Maryland and Colorado.”

• Good: right at the 1,200 W cap in most state laws; UL 1741 listed; long warranty; add a STREAM Ultra later for storage.
• Watch out: panels are sold separately (the panel bundle was sold out when we checked); no power during an outage on its own; only the states EcoFlow names.
• Best for: homeowners and renters in a plug-in-solar state who want the most output allowed.

2. EcoFlow STREAM Ultra: best with a battery

The STREAM Ultra is a 1.92 kWh LFP (lithium iron phosphate) battery with its own grid-tied inverter. It takes up to 2,000 W of panels on four MPPT inputs (500 W each), sends up to 800 W to your outlet on its own or 1,200 W with the STREAM Microinverter, and stacks to 11.52 kWh. EcoFlow rates it for 6,000 cycles to 70% capacity, NEMA 4 water resistance and a 10-year warranty. When the grid fails, EcoFlow says it stops feeding the grid and you can plug appliances straight into its two outlets to run on battery or solar.

• Good: stores midday sun for the evening; doubles as a small outage battery; expandable.
• Watch out: panels extra; same three-state limit as the microinverter; 800 W to the home without the microinverter.
• Best for: people who are out all day and use most of their power after sunset.

3. US Solar Supplier 810W Plug-In Kit: best complete starter kit

This Kentucky retailer’s kit is the closest thing in the US to a German-style balcony kit in one box: two Runergy 405 W panels, an APsystems EZ1 microinverter (up to 900 VA at 120 V) and SunModo racking that mounts the panels like an awning. Warranties: 15 years on the panels’ product and 30 years on performance, 10 years on the microinverter, 20 years on the racking. The retailer is clear that the system has to meet local code and be approved for grid connection before use, and it ships by freight.

• Good: panels, inverter and mounting in one order; long warranties; honest about approvals.
• Watch out: sold out (“contact for availability”) when we checked; certification not stated on the page we read; freight delivery.
• Best for: a house or ground-floor deck where you can mount two full-size panels.

4. Zendure SolarFlow Kit: most storage in one kit

Zendure’s US kit bundles two 410 W rigid panels, the Hub 2000 (up to 1,800 W of solar on two MPPT inputs), two AB2000S LFP batteries (3.84 kWh, expandable to 7.68 kWh), a 900 W microinverter and a smart meter clamp so it can match output to what your home is using. The microinverter is UL 1741 listed with anti-islanding; Zendure says that once the power fails, the microinverters stop. Warranty: 10 years. Zendure gives no state list and asks buyers to “consult the local authorities or professionals.”

• Good: complete kit with storage; smart meter avoids sending power you can’t use to the grid.
• Watch out: sold out and expensive at about $3,932; no backup power during an outage; no state-by-state statement from the maker.
• Best for: a homeowner with yard or deck space who wants storage and is fine waiting for stock.

5. Craftstrom 1200W Eco-Line: most panels in a box

Craftstrom sells a 1,200 W kit of six 200 W panels and three 400 W inverters for about $2,250, and the maker estimates up to 2,160 kWh a year. Read its marketing carefully: the site says the kits are “legal in all 50 states” and need no permits, but only a handful of states have plug-in solar laws, so that claim is the maker’s, not the states’. The page says the inverters are “UL certified” without naming the standard. Ask the company for the UL 1741 listing and your utility for its rules before buying. Its bigger 2 kW + 3 kWh battery kit is above the 1,200 W cap in Utah, Maryland, Maine, Virginia and California and above Colorado’s 1,920 W, so it wouldn’t count as a plug-in device under those laws as written.

• Good: six panels in one order at 1,200 W; in stock when we checked.
• Watch out: legality and certification claims we could not confirm; warranty terms not on the page we read; six panels need a lot of railing.
• Best for: buyers in a plug-in state who have confirmed the listing and have the space.

6. EcoFlow DELTA 3 Plus with balcony panels: best legal-everywhere option

If your state has no plug-in law, there is a simple workaround that involves no utility at all: hang folding panels on the railing, charge a portable power station, and plug a lamp, laptop, router or fan into the station instead of the wall. The DELTA 3 Plus stores 1,024 Wh of LFP battery, puts out 1,800 W (3,600 W surge), takes up to 1,000 W of solar on two 500 W inputs, and expands to 5 kWh with an extra battery. EcoFlow rates it for 4,000 cycles to 80%, under 30 dB at 600 W, with a 5-year warranty. A good balcony match is one or two EcoFlow NextGen 220 W bifacial panels (IP68, 15.4 lb, about $399 each at EcoFlow).

• Good: no grid connection, so no utility approval; doubles as outage backup; moves with you.
• Watch out: it only powers what you plug into it, so you carry the savings by hand; panels cost extra.
• Best for: renters in states without a plug-in law, and anyone who also wants storm backup.

7. Jackery Solar Generator 1000 v2: off-grid kit with a panel included

Jackery bundles its Explorer 1000 v2 (1,070 Wh LFP, 1,500 W, 3,000 W surge) with a SolarSaga 200 W bifacial panel (IP68, 14.33 lb). The station accepts up to 400 W of solar, and Jackery lists about 7.5 hours of solar charging for this kit in good sun. It’s the easy one-box answer if you want sun-charged power on the balcony without picking parts.

• Good: panel included; legal anywhere; light enough to carry inside.
• Watch out: 400 W solar input limits a second panel; one 200 W panel won’t refill it in a short winter day.
• Best for: small apartments that want a solar-charged backup and a lower electric bill on a few devices.

How much will a balcony kit produce?

A simple estimate: daily kWh ≈ panel kW × peak sun hours × 0.8. The 0.8 covers heat, wiring, dust, partial shade and inverter losses (NREL’s PVWatts calculator uses 14% system losses before the inverter by default). Most of the continental US gets roughly 4 to 6 peak sun hours a day on average, less in the Northeast and Northwest, more in the Southwest.

• 800 W of panels at 4.5 sun hours: about 2.9 kWh a day, or about 1,050 kWh a year.
• 1,200 W of panels: about 4.3 kWh a day, or about 1,580 kWh a year.
• Value: at EIA’s 2026 forecast US average of 18.2 cents per kWh, that’s about $190 and $290 a year, but only if your home uses every kWh as it’s made.

These are our estimates for south-facing, tilted, unshaded panels. Panels hung flat against a railing make noticeably less, east or west faces less again, and a north-facing balcony is rarely worth it. The state laws we read don’t promise payment for power that flows back to the grid, so plan on saving only what your fridge, router and other always-on devices use while the sun is up. That’s why many buyers add a battery: see balcony solar with a battery.

How to choose a balcony solar kit

• Start with the law and your utility. If your state has a plug-in law, stay under its watt cap (1,200 W in most; 1,920 W in Colorado). If not, ask the utility or choose an off-grid power station kit.
• Insist on a real listing. Look for a microinverter certified to UL 1741 with anti-islanding, named on the maker’s page. Utah’s law requires UL or equivalent lab certification; Colorado’s references UL 3700.
• Measure the space and the sun. Full-size 400 W panels are big and heavy: check the dimensions and weight on the spec sheet against your railing. Count how many fit, which way they face and how many hours of direct sun they get.
• Mount it safely. Panels on a railing catch wind. Use racking made for the job, follow the maker’s instructions and your building’s rules, and never hang anything that could fall on people below.
• Use a dedicated outdoor outlet on a circuit that isn’t overloaded. If you’re unsure, a licensed electrician can check it (Maine’s law requires one above 420 W).
• Don’t expect federal money. The 25D residential clean energy credit ended for systems installed after December 31, 2025. Check your state and utility for rebates.

Balcony solar kit questions

Can I buy a balcony solar kit in the US?

Yes, but the choice is small. EcoFlow sells the STREAM Microinverter and STREAM Ultra, Zendure and US Solar Supplier sell complete kits (both sold out when we checked), and Craftstrom sells multi-panel kits. Most popular European kits, such as Anker’s Solarbank and BLUETTI’s Balco, were not sold in US versions when we checked.

Is it safe to plug a solar panel into a wall outlet?

Only with a certified plug-in microinverter that shuts off when the grid goes down, on a circuit that can take it, and where your state or utility allows it. Never wire a panel or a generic inverter to a plug yourself. State laws such as Utah’s require UL or equivalent certification and that the device not energize the house in an outage.

How much money does a balcony solar kit save?

Our estimate for an unshaded, south-facing 800 W kit is about 1,050 kWh a year, worth about $190 at the 2026 US average price, if your home uses all of it as it’s made. A vertical or shaded railing makes less, and power sent back to the grid may earn nothing. Treat makers’ payback claims as best cases.

Do balcony solar kits work during a power outage?

A plain plug-in kit doesn’t: the microinverter shuts off when the grid fails, by design. A kit with a battery that has its own outlets, like the EcoFlow STREAM Ultra, or a portable power station charged by panels, can keep a few devices running.

Can renters install balcony solar?

Often, with care. Get the landlord’s or HOA’s OK unless your state’s law protects you (Virginia’s and Colorado’s include protections), follow the state’s watt cap, and use mounts that leave no damage. An off-grid power station with folding panels needs no one’s permission to use inside your home.
