New Jersey just made plug-in solar panels legal. No roof required.

New Jersey just made plug-in solar panels legal. No roof required. For renters, condo owners, and anyone whose roof is shaded, leased, or owned by someone else, that is not a slogan. It is a change in the rules.solarpowerworldonline.com

On September 1, 2026, Governor Mikie Sherrill signed the Garden State Balcony Solar Act (S2368/A4836, now P.L.2026, c.82). The law takes effect March 1, 2027. It legalizes portable solar systems that plug into a standard 120-volt outlet, with a combined output cap of 1,200 watts—roughly two or three modern panels. The panels can sit on a balcony, patio, or sunny yard. A microinverter converts DC to household AC. Excess power is not credited through net metering. Savings come from using the electricity on site.

That is the point. Treat a small solar kit more like an appliance than a power plant.

What the law actually does

The statute defines a “portable solar generation device” as movable PV equipment that:

• outputs no more than 1,200 watts
• plugs into a standard 120-volt outlet
• sits on the customer side of the meter and is meant to offset household use
• is listed or certified to UL 3700 (or a comparable nationally recognized lab standard)
• shuts off exports during a grid outage so line workers are not back-fed

Utilities cannot demand an interconnection agreement, prior approval, extra fees, or extra hardware beyond what is already in the kit. Municipalities cannot ban the devices or require a permit just to place or use them. Building modifications and real electrical work still follow the National Electrical Code and the State Uniform Construction Code. Systems of 400 watts or less are exempt from code provisions that would force changes to wiring or the panel.

Landlords cannot ban a qualifying system if the tenant pays the electric bill. HOAs and condo associations cannot impose blanket bans. They can set reasonable rules on size, location, and placement. Tenants must give at least 14 days’ written notice, name the location, and show the kit complies. The tenant owns the risk of damage from the device.

The bill passed the Senate 40-0 and the Assembly 79-0. Public polling from Fairleigh Dickinson earlier in 2026 found nearly 80 percent support.

Governor Sherrill called it “a practical, easy-to-use tool that can help families save money while allowing more people to participate in our clean energy future.” Environment New Jersey’s Doug O’Malley put it more simply: solar small enough to plug in, big enough to matter for people who could not go solar otherwise.

Specifications and real-world savings

Typical kits use one or two panels plus a microinverter. Hoymiles’ HiFlow Pro is the first U.S. microinverter certified to UL 3700. One 360-watt unit is advertised at up to about 721 kWh per year; four units in parallel can reach the 1,200-watt cap. Bright Saver, CraftStrom, EcoFlow, and generic Hoymiles DIY kits are already selling into this market. Prices run from a few hundred dollars for a starter 180–400 watt kit to roughly $1,500–$2,000 for an 800–1,200 watt setup.

Advocates say a qualifying system can offset 10 to 25 percent of household use, depending on sun and load. New Jersey officials have cited monthly savings starting around $15 and rising toward $50, or up to about $600 a year in a high-rate state where residential power sits near 18 cents per kWh. Those numbers assume daytime use that matches generation. There is no payment for leftover power sent to the grid.

This is not a rooftop replacement. It is a low-friction first step for the large share of New Jersey households that rent or live in apartments.energysage.com

Companies in the mix

A few names keep showing up:

• Hoymiles — first UL 3700-certified balcony microinverter in the U.S. (HiFlow Pro). That certification is the safety keystone of the new state laws.
• CraftStrom — German-rooted balcony specialist selling U.S.-spec kits; CEO Stephan Scherer praised New Jersey’s density and renter base.
• Bright Saver — California nonprofit selling at-cost kits (180 W around $285 for members; 360 W around $414) and lobbying for enabling laws. They have sold systems well beyond California.
• EcoFlow and various Hoymiles/APsystems DIY bundles — consumer electronics and component routes for buyers who want monitoring or batteries.

Consumers get helped when products are listed, anti-islanding works, and the price is low enough that payback is measured in a few years of bill reduction. Consumers get hurt when uncertified import inverters skip anti-islanding, overload a shared circuit, or get sold as if they were full rooftop systems with net-metering credits they do not have.

A national pattern, not a party monopoly

New Jersey is the ninth state with an explicit plug-in solar framework. The list as of September 1, 2026: Utah, Maine, Virginia, Colorado, Maryland, Connecticut, New Hampshire, Vermont, and New Jersey. New York’s SUNNY Act was still awaiting the governor. California’s SB 868 had passed both chambers but was not yet law.

Party control of those nine states is mixed, which matters if the claim is that only one side “helps consumers.”
