In short: Plug-in solar is not banned anywhere in the United States, but whether you can use it without utility paperwork depends on your state. As of 2026, 10 states have passed plug-in solar laws and 35 states in total have introduced legislation. Passed does not always mean in effect yet, and a few states add their own conditions, so the rules are a genuine moving target. The most reliable way to check where you live is our legislation tracker, where you can open your state's bill and confirm its current status and effective date.
"Is it legal?" is the first question most people ask about plug-in solar. The law is in the middle of catching up to a technology that is already mainstream in Europe, and your experience depends a lot on where you live.
The short answer: it is legal to own, but the rules to use vary
Plug-in solar panels are legal to buy and own across the country. What differs from state to state is whether you need an interconnection agreement with your utility before you plug in. These agreements were written for large rooftop systems, and applying them to a small appliance-sized panel is the red tape that 10+ states are now clearing away.
There are effectively three situations you could be in:
Your state has passed a plug-in solar law. These laws treat small systems more like appliances than power plants and, once in effect, generally free a certified kit from the utility interconnection process. Some have already taken effect, others are still phasing in, and a few add conditions, so confirm your state's status and effective date on the bill itself. 10 states are in this group.
Your state has introduced legislation but not yet passed it. Momentum is building, and the rules may change soon. Legislation has been introduced in 35 states in total.
Your state has not acted yet. Plug-in solar is still legal to own, but the older interconnection rules can technically apply even to a tiny panel that doesn't send energy back to the grid.
To see exactly which of these applies to you, check the plug-in solar legislation tracker. We keep it current as bills move, and it links to each state's bill so you can confirm the current status and effective date, which is why we point you there rather than to a list in an article that ages the moment a new bill passes.
What the passed laws actually do
The states that have acted generally create a new category for small portable solar devices, often capped around 1,200 watts, that connect through a standard 120-volt outlet. In exchange for meeting safety requirements, owners are freed from the utility interconnection process. The common threads in these laws are:
A size cap that keeps the systems small.
A requirement that the device be certified by a nationally recognized testing laboratory.
A requirement that the system automatically shut off during a grid outage, which certified microinverters already do.
Utah was the first state to pass this kind of law, and others have followed as lawmakers from both parties have taken up the issue.
Are there states where the rules are stricter?
Yes. Passing a law does not always mean a small system is free to use with no further steps. In a few states, even a small system may still need an interconnection agreement, and at least one state requires a licensed electrician for larger systems. These requirements are still shifting, so before you buy, open your state's bill from the tracker and confirm the exact rules, including whether the law has taken effect.
What to know if your state has not passed a law yet
You can still use plug-in solar in these states, but go in informed:
Interconnection rules may technically apply. A small panel rarely sends energy back to the grid, but if your utility detects backfeed, it could contact you or, depending on your meter, count that energy as consumption. Sizing the system small keeps this backfeed risk to minimum.
Outdoor outlets need GFCI protection and a weatherproof cover, which may call for a small amount of electrician work.
A permit may be required depending on your city and how you mount the panel. Many building departments have not seen an appliance-like solar device before, so expect a short conversation.
How to change the rules where you live
The reason these laws are passing is that residents are asking for them. If your state is still in the "introduced" or "not yet" column, you can help move it along. Bright Saver is a nonprofit organizing exactly this effort, and a $29 per year membership funds the policy work and gives you an easy way to weigh in with lawmakers a few times a year, only if you choose to. You can join without buying anything.

It is legal to own everywhere. Whether you can use it without a utility interconnection agreement depends on your state. 10 states have passed plug-in solar laws, and 35 have introduced legislation.
How do I find out if plug-in solar is legal in my state?
Check the live legislation tracker, which shows the current status for every state, links to each state's bill, and updates as bills move.
What states allow balcony solar?
10 states have passed plug-in (balcony) solar laws as of 2026, with many more considering them. Because the list changes and not every law is in effect yet, the tracker is the most reliable place to confirm your state's status and effective date.
Do I need a permit for plug-in solar?
It depends on your city and how you mount the system. Some jurisdictions require one and many do not, especially in states that have passed plug-in solar laws.
What happens if I use plug-in solar in a state that has not passed a law?
It remains legal to own and use, but older interconnection rules can technically apply, and you may want to keep the system small and confirm your local utility's requirements.
Bright Saver is the first and only nonprofit in the United States dedicated to plug-in solar, also known as balcony solar, built on a simple premise: no American should have to choose between saving money and fighting climate change. We sell our members these small plug-in systems at cost, the kind anyone can set up on a balcony, patio, or other small space, and we have already helped pass laws in 10 states that make it cheaper for people to power their own homes. Check your state on the legislation tracker, or join for $29 a year to help change the rules.
