Net metering & export compensation
Monthly retail-rate netting plus solar adjuster (varies by system size and REC ownership).
Interconnection process
PUC Rule 5.500 interconnection; Certificate of Public Good is required even for small residential systems via the simplified Net Metering Application.
Permitting & inspection
VT PUC issues the CPG; local jurisdictions handle building inspections.
Utilities operating in this state
Green Mountain Power, Vermont Electric Cooperative, Washington Electric Cooperative, plus municipal departments (Burlington Electric, Stowe, etc.).
Electrical code (NEC) considerations
The U.S. National Electrical Code (NEC) does not have a listed pathway for backfeeding a standard 120 V receptacle from a solar inverter. Article 705 covers interconnected power production sources and generally expects a dedicated, breakered, labeled circuit. Many AHJs that follow NEC 2017/2020/2023 will not approve a cord-and-plug PV connection on that basis, regardless of state policy.
HOA, landlord & solar access
Check your lease, HOA covenants, and condo rules. Many states have a 'solar access' or 'solar rights' law that limits HOA restrictions on rooftop PV, but those statutes were written for permanent installations and rarely mention plug-in or balcony kits explicitly. Renters almost always need written landlord permission.
Official sources to consult
- DSIRE — state policies & incentives
- Vermont PUC
- Your specific utility's interconnection application and net metering / net billing tariff
- Your local building department (the AHJ that will inspect any work)
Bottom line for plug-in solar buyers in Vermont
Even where state policy is favorable, U.S. utilities and inspectors generally do not recognize a cord-and-plug PV connection. If you want to be fully code-compliant and earn export credits, plan on a permitted, hard-wired install by a licensed electrician with a signed interconnection agreement. Off-grid uses (running a single appliance, charging a battery, RV/shed power) avoid most of these rules but still need to follow product instructions and basic electrical safety.
