PVTIME – Several US states are driving growth in the plug-and-play solar sector by introducing targeted legislation that removes the need for prior approval for installations. As of 15 May 2026, Utah, Virginia, Colorado, Maine and Maryland had formally legalised these systems, also known as ‘balcony solar’. These compact, portable devices connect directly to home circuits, providing access to renewable energy for those unable to install rooftop or community solar systems, such as tenants and apartment dwellers.
Colorado Governor Jared Polis recently signed House Bill 26-1007, also known as the Improve Customer Use of Distributed Energy Resources Act. This legislation prohibits electricity suppliers from demanding prior approval for the installation or use of portable solar systems and restricts them from imposing unreasonable limitations on their operation. The state’s Public Utilities Commission must update grid interconnection rules by 31 December 2026 to allow certified meter interface adapters.
Maryland has also implemented House Bill 1532, the RELIEF Act, which defines plug-and-play solar as portable systems with a maximum rated output of 1200 W that are connected via standard sockets. Residents installing such systems only need to notify local utilities; no approval or associated fees are required. A comparable bill in Connecticut has passed both legislative chambers and awaits gubernatorial signature.
By March 2026, over 30 US states had introduced legislation related to plug-and-play solar. Will Toor, Director of the Colorado Energy Office, noted that the widespread adoption of these small systems, particularly when combined with energy storage, would lower users’ electricity bills and enhance grid reliability during peak demand.
The US approach is partially inspired by Germany, which has over 13 million operational plug-and-play solar systems. According to German BVSS CEO Craig Morris, unlike Germany’s federal-led promotion, the US is progressing through state-level legislation, with more than 29 state legislatures currently reviewing related proposals.
