Current status
Signed—not effective
The law has been enacted but its new route is not available yet. Prepare now, then re-check the final implementation on the effective date.
Check your location
Framework status and exact product eligibility are separate checks.
What this means today
New Hampshire's SB 540 is signed and scheduled to take effect July 27, 2026. The short gap still matters: before that date, the new framework is not yet the governing route. Identify the serving utility and request launch guidance rather than relying on a retailer's compatibility claim.
The dataset tracks 1,200 W. Verify a complete US configuration and plan for snow, wind, ice and seasonal shade. Eversource, Unitil, Liberty, New Hampshire Electric Cooperative and municipal territories may use different contacts and procedures. No export credit is assumed.
What SB 540 says
The New Hampshire General Court record for SB 540 is the primary source; the dataset records a 1,200 W category effective July 27, 2026.

Your serving utility still matters
Law not effective as of verification date.
Pre-purchase checklist
- 1Confirm continuous inverter AC output is no more than 1,200 W; panel DC nameplate watts are a different measurement.
- 2Ask the serving utility for its current New Hampshire notice, registration, metering and export procedure.
- 3Verify complete-system safety evidence, anti-islanding, plug and branch-circuit requirements; a listed component is not a listed system.
- 4Obtain landlord or HOA consent and check local electrical, planning, fire and structural rules.
- 5Do not rely on the new framework before July 27, 2026.

Frequently asked questions
Can I use plug-in solar in New Hampshire today?
The tracked law is signed but not effective until 2026-07-27. Until then, follow the rules and utility process currently in force.
Does the watt limit refer to panel watts?
Do not assume so. Compare the final law’s definition with continuous inverter AC output; panel DC nameplate capacity is a different figure.
Will exported electricity be credited?
No export payment or retail credit is assumed here. Ask the serving utility how the meter treats surplus generation and size around daytime self-consumption.
Does a compliant product remove landlord or HOA rules?
No. State energy rules do not grant permission to alter a rented home, common property, balcony rail or façade. Obtain written consent and check local requirements.
Is system-level UL 3700 certification verified for these products?
No product is presented here as having verified system-level UL 3700 evidence. Confirm the precise complete-system listing and all conditions before purchase.
