A bill record is not permission to connect
Plug-in solar requirements can involve state law, the law’s effective date, utility notification, equipment limits, electrical code and property conditions. This page links selected legislative records rather than making an unsupported nationwide “permit-free” claim.
Check the enacted text and effective date, not just the introduction or signature date. Our earlier edition’s five-state headline has been removed because it mixed signed legislation with laws already in effect.
Selected primary bill records
| State | Primary record | What to verify |
|---|---|---|
| Utah | HB 340 (2025) | Enacted status, effective date, eligible capacity, certification, notification and installation conditions. |
| Colorado | HB26-1007 | Enacted status, effective date, eligible capacity, certification, notification and installation conditions. |
| Maryland | HB1532 (2026) | Enacted status, effective date, eligible capacity, certification, notification and installation conditions. |
| Maine | LD 1730 | Enacted status, effective date, eligible capacity, certification, notification and installation conditions. |
How to verify in any state
- Identify the utility that serves your address, including any cooperative or municipal utility.
- Read its customer-generation and interconnection pages.
- Search your legislature’s official bill record and enacted statute.
- Ask the local electrical authority about the exact listed system and connection method.
- Obtain written confirmation of required notices, permits and property permissions.
For states not listed above, no permission or prohibition is implied. We have not independently confirmed all 50 states’ current plug-in rules. The interactive calculator is a financial planning tool, not an installation authorization.
Safety and utility operation still matter
Confirm protective features, approved wiring and outage behavior. Do not connect a system based solely on a seller’s general claim of “legal everywhere.” Keep product documentation and the utility’s written response.
