New Jersey Legalizes Plug-In Solar to Cut Household Energy Costs

Governor Mikie Sherrill on Sep. 1 signed the Garden State Balcony Solar Act, opening the door for New Jersey residents to install qualifying plug-in solar panels without many of the regulatory hurdles that have limited their use. The legislation allows certified portable solar systems of up to 1,200 watts to connect through a standard 120-volt household outlet without utility interconnection approvals, metering requirements, or related fees, creating a simpler path for households to lower electricity costs through small-scale solar generation.

The measure is designed to expand access to solar for renters, apartment residents, and homeowners who cannot install conventional rooftop systems. It also limits the ability of landlords, homeowners’ associations, and municipalities to broadly prohibit qualifying plug-in solar devices, while still allowing reasonable restrictions on placement and installation. The law preserves electrical safety requirements by limiting streamlined treatment to certified equipment that automatically disconnects during power outages.

The legislation builds on Governor Sherrill’s broader effort to reduce energy costs while accelerating clean energy deployment across the state. Since taking office, the administration has approved 18 solar and battery storage projects, expanded New Jersey’s community solar program to 3,000 megawatts, advanced grid modernization initiatives, and adopted additional measures affecting utilities and large electricity users. Together, those actions are projected to save New Jersey ratepayers about $1 billion annually.

New Jersey’s action reflects a broader national shift toward plug-in solar as states pursue faster and more affordable ways to expand distributed renewable energy. More than half of U.S. states have introduced or advanced legislation on plug-in solar this year, driven by rising electricity demand and growing interest in customer-owned generation that can offset on-site consumption.

Colorado, Connecticut, Maine, Maryland, New Hampshire, Vermont, and Virginia have enacted statewide frameworks this year, joining Utah, which established the first dedicated legal framework for plug-in solar in 2025. Most of those laws set a 1,200-watt limit, eliminate prior utility approval and related fees for qualifying systems, and require compliance with recognized electrical safety standards. Some states have adopted different approaches, including Colorado’s 1,920-watt limit and Maine’s tiered installation requirements for larger systems.
