Plug-in solar in Vermont
Vermont's plug-in solar law is in effect. It allows up to 1,200 W combined per meter, names UL 3700 as the product standard, and is one of the few state laws that speaks directly to renters.
What is Vermont's power limit?
One or more devices per electric meter, with a maximum combined inverter capacity of not more than 1,200 W. A device may only be connected to a system that uses a smart meter.
Do you need to tell your utility?
The act does not require notification to the utility. The utility may not require approval before installation or use, or fees, and the device is exempt from 30 V.S.A. 248 and interconnection agreements. Two conditions apply: a device may only be connected to a system using a smart meter, and a customer who already has a net-metering system may not also install a plug-in device. Any electricity exported to the grid is not compensated.
What if you rent?
Vermont's law addresses tenants directly: a tenant gives the landlord 10 days' notice before installing a device. The landlord then has 10 days to respond with reasonable restrictions on the device; if the landlord does not respond within that period, the tenant may proceed.
What certification does Vermont require?
The device must comply with UL 3700 for plug-in photovoltaic systems by UL Solutions, or an equivalent certification by an equivalent nationally recognized testing laboratory, and be installed and operated in compliance with IEEE 1547-2018.
How Vermont differs
Vermont is one of only two enacted laws here that name UL 3700 specifically, and one of the few that addresses renters: a tenant must give the landlord 10 days' notice. It requires no utility notification.
