What does your state ask before you plug in?
Ten states have signed a plug-in solar law, and each asks for different things: a certified kit, a size cap, sometimes a note to the utility or the landlord first. Pick your state, your kit and your home, and get the steps in order, each with the law's own words.

State law: plug-in solar is legal here. Checked Nov 12, 2026.
- What the law says
800 W is within the 1,200 W cap
Compare the output on the kit's label with how the law measures it, below. If the law counts every kit on an address or meter, add them up.
Size cap in the law1,200 W: maximum power output; one device per meter; 120 V outlet; not permanently affixed to a structure
- State law asks
Check the label for the certification the law names
The law names outage protection, IEEE 1547 and UL 1741. Look for the testing lab's listing mark on the kit, not just the seller's word.
Certification in the lawUL or equivalent NRTL and UL 1741; NEC, IEEE 1547, State Building Code; outage protection

No utility notice in the law
The law sets no notice step. Your utility can still tell you how it bills power that goes out.
Utility rules in the lawNo approval or extra equipment, and no fee or charge related to the device except charges it incurs through its use (power it sends to the grid can be billed as usage).
- Check first
Check your meter: power you send out can be billed as usage
On a meter that only counts one way, power the kit sends to the grid can show up as power you used. Ask your utility what your meter does before you plug in.
In the lawDevice must warn that generation above on-site use is charged as usage unless the meter allows net metering.
What your meter does with a kit → - Good practice
Check the circuit before you plug in
The breaker can't see the power a kit adds at the outlet. Keep heavy appliances off that circuit, or use one with nothing else on it.

Short forms of each law's wording in our state table, read in the statutes (state table last checked ). The checklist quotes the full wording. "Utility may ask" means the law lets the utility ask for a notice or registration. "Lease decides" means the law sets no landlord rule. Other states: no plug-in solar law yet, or a bill that hasn't passed; pick one above for what that means.
Plug-in solar steps by state
Do I have to tell my utility about a plug-in solar kit?
In Maryland and Virginia (from Jan 1, 2027), state law asks for notice before installing. In Maine, above 420 W, within 30 days. In California (from Jan 1, 2027), Colorado and New Hampshire (from Jan 1, 2027), the utility may ask you to report or register it. Connecticut, New Jersey (from Mar 1, 2027), Utah and Vermont: no notice in the law.
Do I need my landlord's permission?
In New Jersey (14 days, from Mar 1, 2027), Vermont (10 days) and Virginia (7 days, from Jan 1, 2027), the law sets a notice process for tenants instead. Where the law says nothing about landlords, your lease decides. The checklist links to a letter matched to your state.
Can an HOA or condo association ban a balcony solar kit?
In Colorado, New Jersey (from Mar 1, 2027) and Vermont, the law limits bans, though associations can still set reasonable rules. In Virginia (from Jan 1, 2027), the law says it doesn't override HOA covenants or condo documents. Elsewhere the law is silent, so the association's rules decide.
What if my state has no plug-in solar law?
Then your utility's normal interconnection rules apply. Ask your utility what it requires before you connect anything, and if you rent, ask your landlord. Your state's page shows any bill that's moving.
Is anything I enter saved?
No. The checklist is built in your browser from our state table, and nothing you pick is stored. Our analytics counts only which state was chosen, never your kit, home or address.
How the checklist works
Each law step comes from our state table, which is filled only from statutes and official state pages and shows "Not verified yet" for anything we haven't read in the law. The checklist sorts that wording into steps: when to tell the utility, whether your kit is inside the size cap and any wattage clauses, what the certification wording names, what happens to power you send out, and, if you rent or have an HOA, what the law says about them. Every law step shows the law's own wording, so you can check our reading.
Steps marked "Good practice" aren't law: they come from our outlet check and certification guide. Laws change; a law that is signed but not in force yet shows its start date first. Nothing you pick is stored; our analytics counts only which state was chosen. General information, not legal advice.
