New Hampshire rules and sources
Statutes checked October 1, 2026
Signed · takes effect January 1, 2027Is plug-in solar legal in New Hampshire?
Not yet, but it is signed. N.H. RSA 362-A:1-a, IV-a; 362-A:10; 374:1-b; 155-A:16 (2026 N.H. Laws ch. 262) takes effect January 1, 2027. Until then your utility's rules for small customer generators apply, so ask before you plug in. From that date, the law allows one plug-in system up to 1,200 W of AC inverter output, plugged into an ordinary outlet. One system per metered customer. It must meet the applicable building code and certification requirements.
What the statute says
These provisions apply from January 1, 2027, only to a qualifying device. They are not permission to install today.
| Cap | 1,200 W of AC inverter output. |
|---|---|
| Systems | One per metered customer. |
| Utility notification | Not required; the statute lets the utility ask for it after installation. |
| Interconnection fees | None: the utility cannot charge an interconnection fee. |
| Local permit | The statute does not settle it. Check with your county or city before you mount anything. |
| Electrician | Not addressed by the statute. |
| HOA | Not preempted: your HOA keeps its say. |
| Landlord | Not preempted: a landlord can refuse. |
| Net metering | Not stated. Size for what you use in daylight either way; a plug-in system is not a net-metering system. |
| Certification named | No standard named in the text. |
| Our kits | Unresolved system certification needs clarification |
Before you buy for New Hampshire: The law calls for certification to standards for distributed energy resources and plug-in solar generation systems. We have not established that our kit meets that system requirement; an inverter listing alone does not settle it. Read the cite and decide with that in front of you.
