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.

Your plug-in solar checklist for Iowa

State law: no plug-in solar law yet. Checked Nov 12, 2026.

  1. Check first

    No plug-in solar law in Iowa yet

    No plug-in solar law in Iowa as of Nov 12, 2026. Your utility's normal interconnection rules apply.

    Iowa law page →
  2. State law asks

    Ask your utility before you connect

    Without a plug-in solar law, a kit that feeds power into your home falls under the utility's normal interconnection rules. Ask what it requires for a small system.

  3. Good practice

    Pick a certified kit anyway

    Every signed state law names certification by a testing lab, and UL 3700 is the standard written for plug-in kits.

    How to check a certification →
  4. 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.
