Why the answer varies
Electricity interconnection is shaped by state law, utility tariffs, electrical code and local enforcement. Property rules add a separate layer. A state can exempt a qualifying device from a utility agreement without giving permission to attach panels to a rented balcony.
What an enacted framework usually defines
Recent laws tend to define the device, cap aggregated AC output, require recognized complete-system certification and require isolation during outages. The details are not interchangeable: use the actual statute for the state and effective date.
How to verify an address
Identify the electric utility, read the current state statute or regulator guidance, check the authority having jurisdiction, confirm property permission and match the exact product configuration to the required certification. Keep copies of the sources and written responses.
What does not count as proof
A retailer’s shipping availability, a social-media installation, a proposal that has not passed, or UL certification on one component is not conclusive. When evidence is incomplete, the responsible answer is “not verified,” not “probably allowed.”
Before you buy
- Confirm the current state, utility and local requirements for the exact address.
- Match certification evidence to the complete system and exact configuration.
- Verify safe mounting, the intended circuit and any landlord or association permission.
- Calculate savings from realistic production and onsite use, not headline wattage.
Quick answers
Which states have plug-in solar laws?
Our primary-source review found enacted specific frameworks in Utah, Colorado, New Jersey and California, with conditions and effective dates that differ.
Is plug-in solar legal if it is under 1,200W?
Not automatically. A wattage cap is only one condition in some laws; certification, isolation, utility and property rules still matter.
Can a utility ban plug-in solar?
Utility authority depends on the applicable law and tariff. Some enacted state laws restrict approval requirements for qualifying devices.
